Starday Wishes / Re: Happy Starday, Pangaea!
« on: July 14, 2021, 07:20:22 PM »
Hello, Gang of Five!  :olittlefoot :CeraHAPPY :ducky :petrieooohh :^^spike

I don’t know how many of you are left who have been active long enough to remember me when I was on the forum (roughly mid-2009 to 2013, with a few scattered posts through 2015), but I’m back just for today to celebrate a very special occasion:

11 years ago today, in this very thread, one of my best (and most dearly missed) friends on this forum—Malte279—introduced me to the concept of "schnappszahl” birthdays. A schnappszahl is a number consisting of a single repeating digit, and the name—German for “liquor number”—references the fact that these birthdays are considered particularly special in German culture. Incidentally, I am roughly 14.5% German (on my paternal grandfather’s side), but more significantly I’ve always had a fascination with numbers, dates, and words that are noteworthy in some way, not necessarily in meaning but the structure of the number/word itself. I also love any opportunity/excuse to let my oddball flag fly by celebrating something out of the norm. (Did I ever share the childhood story about the time my siblings and I invented “Cheese Day”?) So schnappszahl birthdays appealed to me immensely. I’ve celebrated every schnappszahl birthday in my family ever since, and whenever I see a friend turning 11, 22, 33, 44, 55, 66, 77, 88, 99, or 111 (though I have yet to witness someone turning 99 or 111), I make sure to pass on the knowledge of schnappszahl birthdays.

So for my third schnappszahl birthday, on the first schnappszahl anniversary of learning about schnappszahl birthdays, I felt obliged to drop by and commemorate the occasion. Thank you, Malte279, wherever you are! I hope we can get back in touch sometime. :DD

Note: if Google is to be trusted, it’s more commonly spelled “schnapszahl” with one ‘p’, but Malte—a native German speaker—spelled it with two when he introduced the word to me, and I’m sticking with that. (I think the word looks better with two ‘p's anyway.)

Wow!  I don’t think I've even thought to check this thread since 2014 since I’ve spent so much time inactive and figured I shouldn’t expect any starday wishes.  I certainly didn’t think anyone would bother to update the thread this year.  Thank you all! :DD

You know, I think Spike would do well if he was in a sport that catered more to his strength.  Like that of Wrestling.
Yeah, that's just what I was thinking. :yes

I also bet that Cera would go for Football.  She would try out for probably something defensive, like the Lineback.
I know next to nothing about football, but I bet Spike would be pretty good in a defensive role, too, being big, heavy, low-slung, and powerful, with a tail specialized for whacking things.

Quote
She would also stand up to coaches that make Football a "Boys Only" Game. :D
Stand up to them? I think she'd do more than that! :blink: We've never seen Cera in a situation in which someone told her she couldn't do something because she was a girl, but if anyone ever did, I'd advise them to run for their lives! :lol

^ I imagine Ducky would also do well if running track were involved. She's a pretty fast runner as well. Remember her keeping ahead of the fast biter in LBT XI? That was impressive. :o

Of course, Ruby would be the track team champion by far. :p

Actually, I think all of the gang would do well in Phy Ed, considering all the playing, traveling, and running they do. Spike might not be nearly as proficient as the others in some activities, being the slowest among them (except for Petrie when he's not in the air), but he's very strong physically.

Role Play Discussion / An idea for a Reboot "Members Meeting Chars" RP
« on: December 14, 2016, 07:10:39 PM »
I had a blast with the original RP, but sadly my passion for LBT is not what it once was, and I doubt that I would be able to find the time to compose posts with any degree of regularity. That said, I wish this reboot the best of luck, and hope you all have tons of fun. :)

Just to be clear, will participants be doing the same thing as we did in the original RP; playing "self-insert” OCs, with canon LBT characters played additionally? (Somehow, when I first skimmed these posts, my easily-mixed-up brain got the impression that some of you would be playing yourselves as canon LBT characters.)

I had hoped to offer some ideas for discussion regarding the different ways characters in the “Set-in Memories” and “Amnesiac” categories could be played, but for the life of me I can’t articulate them. :wacko So for the benefit of others who might potentially be uncertain about the categories, let’s just see if I have the basics straight:
  • “Set-in Memories” characters have no human memories, but they have histories within the LBT world as if they had always lived there (e.g., childhood memories; familiarity with LBT-specific customs, places, and terminology not revealed within the official series). Basically, they’ve had their human memories erased, but new memories implanted to allow them to integrate into the LBT world.
  • “Amnesiac" characters have no memories of human or LBT lives. Perhaps they retain a subconscious understanding of the LBT world based on their familiarity with the series (e.g., they know what the Great Valley is and can recognize a sharptooth when they see one), but they have no new memories added.
Is that about accurate?

Silver Screen / Mythbusters
« on: November 13, 2015, 04:01:12 AM »
A part of me died when I learned that MythBusters was ending. :cry Given how generally dispirited and unmotivated I've been these last few weeks, I think the grief is still affecting me. It's more than the end of one of the greatest shows in television history; it's the death of one of the brightest stars in a sky befogged with science illiteracy. Since the axing of Dirty Jobs, MythBusters has been my last reason to pay any attention to the Discovery Channel (excepting the rare Shark Week documentary that purveys something other than fearmongering, sensationalism, and outright propaganda [see Megalodon]). If it was Discovery's choice to end one of their flagship showsóone of their most popular and classic series everóthen I will not be surprised in the slightest if business for them takes a disastrous downward slide. (I've long worried that MythBusters' audience might be decreasing because many of its viewers are the same people who once flocked to Discovery for the science and education programming on which it originally built its reputation, and now that the channel and most of its branch networks are backed up with televisual sludge, they are no longer watching as much.)

I've been watching MythBusters for twelve years, and it has influenced me immensely. I first watched it mainly for its animal myths (indeed, my family first subscribed to cable so that my siblings and I could watch more animal shows), but quickly grew to appreciate the quirky and creative hosts; their unorthodox approach to the scientific method, and their journeys of trial, error, and discovery in search of answers. I soon learned to appreciate the wide variety of subjects they tackled. Over the years, I grew to love the blooming-flower-like beauty of explosions, absorbed more knowledge about physics than I had from my entire grade school education, learned how dozens of familiar devices functioned when I'd never even stopped to think about how they worked, developed a new appreciation for the art of building everything from muppet sharks to paper crossbows, was inspired and empowered to try my hand at constructing unique creations like my azhdarchid costume, became fascinated with animal color perception, was introduced to the hobo dinner, was indirectly tutored in how to speak in the most hilarious pirate voice ever, :lol and had myriads of my long-held impressions and assumptions about reality utterly upended. I saw things on this show that I never imagined were possible, from a lead balloon rising into the air to an elephant recoiling at the sight of a mouse. In short, MythBusters broadened my horizons by an incalculable degree. I weep for future generations if episodes of this amazing show are not regularly rerun, and hope that Discovery at least cares enough to provide MythBusters fans like me with complete, readily accessible copies of episodes, aftershows, and cut material, whether via DVD, YouTube channel, or iTunes downloads.

I have purchased tickets for Jamie and Adam's live stage show "MythBusters Unleashed: Jamie's Farewell Tour" in Minneapolis on November 18. If, by chance, any of my fellow GOFers will be attending the same show, I would love to meet up. In any event, I look forward to seeing the MythBusters in person, and just maybe getting the chance to thank them face-to-face for all the ways they have enriched my life, the lives of what must be hundreds of thousands of other people, and the field of science education.

I have decided that from here on in, whenever someone asks me a question, I will notify them by PM as soon as I answer it. That way, I hope to save you the trouble of checking this thread over and over again just to see if I have gotten around to answering your question.

I do have a part dinosaur-related question, involving the recent new discoveries about Spinosaurus. Since then, I've considered it to be like a mix between a crocodile and grizzly bear. I even thought about it being like its version of a stork, which got me to thinking:
Is there a remote possibility, though there is no record of it (as of now?), that if it got a hold of a small enough fish, it could swallow it whole, much like the way many aquatic birds do?
Spinosaurus almost certainly swallowed food whole. Its teeth certainly weren't any good for chewing, and I’m guessing the most it could have done as far as breaking up a large prey item was by pinning it down and ripping off strips of flesh, the way a bird of prey, a Komodo dragon, or a crocodile would. I don’t know much about the throats of Spinosaurus and other theropods, and how far they could distend to swallow food, but birds and reptiles today can swallow astonishingly big mouthfuls, as demonstrated in a number of videos that can be found on YouTube: this X-ray video of a tawny owl swallowing a bolus of food,
a darter (not a heron as the title claims) eating two fish, and a perentie (an Australian monitor lizard) catching and consuming a rabbit. (The last video is perhaps not recommended viewing for people who are sensitive about watching small mammals being eaten alive; you may console yourself with the knowledge that this is a wild reptile helping control an ecologically destructive invasive species.)

Quote from: Ptyra,Oct 5 2014 on  02:58 AM
Another dinosaur question relates to the Dromaosaurs. The more we learn about that family, the more bird-like they become. There's evidence to suggest that they were fairly intelligent. Could they have been intelligent enough to imitate human speech? I might never do it, but I'm considering writing a small AU Jurassic Park story as if it were being told in the modern era with all the new information we have. Some of which being tiny, feathered Velociraptors that are relatively annoying ankle-biters but not actual threats. I'm considering one of them hanging around with people enough that she starts imitating speech, which includes picking up on the "You didn't say the magic word" thing, and no one knows where she got it from until it was too late. Would it just be a bit of JP goofiness that would only serve the story (kinda?).
Hmm…the idea sounds a little far-fetched to me (but no more so than the dromaeosaur antics we’ve seen already in the JP series). It seems to me that the biggest issue isn’t whether dromaeosaurs were “intelligent” enough to mimic human speech, but whether their vocal apparatuses were capable of making the requisite sounds.

The reason some birds are able to imitate human speech is because of their sound-producing organ, the syrinx. Unlike our larynx (voice box), which is located high in the throat, a bird's syrinx sits deep in the chest, at the point where the lungs split off from the windpipe. Instead of vocal cords, there are membranes on the walls of the syrinx which can be made to vibrate at different frequencies, allowing some birds to mimic human speech sounds even though they have no lips or teeth. Some birds can even modulate the airflow from one lung independently of the other, allowing them to sing two notes at once.

The question is, did dromaeosaurs have a syrinx? Honestly I'm not 100% clear on the answer. The sources I've read imply that syrinxes themselves don't fossilize, but apparently one requirement for possessing a syrinx is a system of air sacs within the bones and body cavity, namely the clavicular air sac, meaning that if a dinosaur had a clavicular air sac, it may have had a syrinx (though we can’t tell for sure). Unfortunately, there are (according to at least one trusted resource) only three groups of archosaurs known to have had clavicular air sacsópterosaurs, the large theropod Aerosteon, and true birds of the group known as Ornithothoracesóand it is believed that all three evolved these air sacs independently of one another. I don't know if there's any evidence as to where on the bird-theropod family tree the clavicular air sac inherited by present-day birds first appeared, or at what point after that the syrinx itself evolved, but the case may be that dromaeosaurs didn’t have them. Even if they did, it’s no guarantee that they were good mimics; only a few of the 10,000+ bird species alive today are capable of replicating human speech, and all of them belong to the parrot and passerine (songbird) families.

That said, the dinosaurs in the Jurassic Park series certainly don’t adhere to paleontology’s predictions of what sounds they could make. For example, many paleontologists doubt that Tyrannosaurus was capable of roaring; it more likely bellowed, rumbled, growled, or hissed in the manner of an alligator.

I for one would love to see more research in the area of dinosaur (and pterosaur) vocalization: the internal structure of hadrosaur crests and what sounds they could have made; whether the hyoid bones of various dinosaurs might have influenced their vocal abilities; experiments with inflatable sacs and other soft tissues that might have served to resonate or modulate sounds; and so on. Until the vocal capabilities of Velociraptor and other dinosaurs are further researched, however, I would say giving your raptors the capacity to imitate human speech would be considered scientifically unlikely, but not necessarily impossible.

Now, it’s one thing for a creature to be able to mimic human words and phrases, but it’s something else entirely to grasp the meanings associated with them and to use them in the proper context. Human communication is extremely complex, and even especially “smart” animals with the capacity to mimic our language probably don’t usually understand the meaning and context of the phrases they repeat unless they’ve been expressly taught those connections (the most famous case probably being the late, great Alex, the African gray parrot).

However, it’s actually not that uncommon for animals to use communication signals to manipulate other creatures. For example, many prey animals, from squirrels, to monkeys, to antelopes, are attuned to the alarm cries of birds, recognizing that if a nearby bird makes a certain call, it means that it has spotted a potential threat. But at least one bird, the drongo, has twisted this to its advantage when foraging alongside meerkats (as seen in this amazing clip from the BBC series Africa). If it sees a meerkat unearth a particularly succulent morsel, it will give a false alarm call. When the meerkats run for cover, assuming a predator has been spotted, the drongo swoops down and helps itself to the abandoned meal. Moreover, the drongo has learned to mimic the alarm calls of other local bird species, and even the meerkats’ own sentries, as a backup strategy for when its hosts wise up to its false alarms. Even we humans aren’t safe from manipulative interspecies communication: as any cat owner could probably tell you, our beloved feline companions are masters of singling out the most pitiable, heartstring-tugging cries to use in persuading their owners to fill up the food dish, open the door, or otherwise give shower them with attention. One study found that the “solicitation purr” uttered by many cats contains a high-pitched element with a very similar frequency to the cry of a human infant. It’s not true mimicry, but it evokes the same nurturing response from us, and requires no research into human psychology and language on the part of the cat.

Here’s a scenario that I think might be feasible: the raptors in your story have the natural ability to mimic the sounds of other species for some natural purpose, such as impressing potential mates with their vocal repertoires (as lyrebirds do), or imitating the calls of more threatening animals to scare away predators approaching their nests or competing scavengers at a carcass. This particular dromaeosaur develops the habit of mimicking things she hears humans regularly say. To me it would be very feasible if she were to hear the “You didn’t say the magic word” phrase looping over and over again, learn to mimic it, and on a later occasion when she repeats it, it turns out to fit the context of the situation perfectly. For a more deliberate and sophisticated use of human-speech mimicry, let’s say the raptor hangs around the JP offices, and regularly hears the boss shouting, “Dennis, come to my office!” She starts mimicking it out of habit, and then learns that whenever she does so, Dennis gets up from his desk and leaves his snacks unprotected. So she develops the habit of mimicking the boss’s call, and as soon as Dennis leaves his desk, she swoops in and feasts on his beef jerky. It’s the same principle as the drongo fleecing the meerkats; the raptor would not need to understand anything more complicated than “when I make this human noise, that guy leaves his food”. Even if real dromaeosaurs weren’t “smart” enough to do this, it would certainly be a far less anthropomorphically exaggerated portrayal of their cognitive abilities than seen in the Jurassic Park films.

Have you seen The LEGO Movie?
Nope. :p I’ve heard good things about it, but it’s one of those films whose animation style just doesn’t appeal to me that much. Also the theatrical trailer gave me a bad first impression that left me disinclined to see it; even when I learned of its critical acclaim, I had little interest in seeing it. At any rate, it’s not very high on my list of movies to watch.

Role Play Discussion / Members Meeting the Characters
« on: March 21, 2015, 10:45:46 AM »
Unfortunately, it is probably safe to say that the "In The Land Before Time" RP has indeed fallen by the wayside, due to the unavailability of several crucial players and my own flagging enthusiasm in keeping it going. The RP was always going to end this way, I think, right from the moment I took up the post as GM. I hate conclusions, especially ones that put a permanent end to something by saying, "That's it, it's over. The end. Nothing more's ever gonna happen." I never like to close the door to the possibility of a continuation someday, no matter how tiny that possibility may be. Hope springs eternal, I guess.

Sad to say, at this time even I have little to no motivation to continue this RP. Most of my previous activity was invested in The Big Water subplot, which has dried up (so to speak) in the absence of FlipperBoidSkua and other key players. If those members (and other former participants) were to return with the express intention of continuing the RP, perhaps I would be willing to revive it. For now, however, I suppose I may as well officially declare this RP closed, at least for the time being. :neutral

Sorry to disappoint you, MC CJ's Revenge. :( As The Chronicler said, you are welcome to start a new RP with the same theme as this one (GOF members entering the LBT world). Just be sure to establish it as a separate RP from this one, so the players don't accidentally post in this RP or its discussion thread. :goodluck

The Fridge / Merry Christmas
« on: December 26, 2014, 01:09:40 AM »
Hello, my old friends; it's been too long.

A lot has happened to me in the past year: my mom got a new job in Nevada; I took two semesters of graduate school at the University of Minnesota to earn a certificate in environmental education; one of my brothers returned from a year in China, while another spent a month in Namibia (leaving me as the only person in the family who has never been outside the U.S.); and I built and wore the largest and most elaborate Halloween costume I think most of the people I met that season had ever seen. It was a year filled with frustrations, regrets, and bouts of depression (some of them rather severe). One of those regrets was that I did not spend more time on the GOF; that I have neglected my beloved forum to the point that I have virtually slid into obscurity. I felt that the least I could do was drop in to say hello on Christmas Day.

This was a very atypical Christmas for me. For one, the whole family convened at my mom's new house in Nevada; the first Christmas I think I've ever spent outside my hometown. The change in scenery permitted us to do something we have never been able to do in Minnesota: open our presents outside. :p Instead of the aluminum Christmas tree and decorations we usually dig out of the garage every year, we had a four-foot high tabletop tree with no decorations apart from pinecones (which we also moved outside along with the presents). One of my Christmas gifts was my first new cell phone in nearly nine years (and my second cell phone overall). :wow The phone was accompanied by a card depicting a Tyrannosaurus attempting to place a star on top of a Christmas tree, inside which my parents had written, "If you can find 10 things wrong with this picture, you can keep this phone." :lol And at dinnertime, for the first time ever, I ate dates stuffed with cream cheese (a traditional Christmas dinner treat from my mother's side of the family, which I had never heard about before).

I'm not sure what else I can say for now, other than that I've missed you all, and wish you a very happy holiday season. :celebrate

Saurus Rock: Member Hall of Fame / Award voting 2014
« on: September 12, 2014, 03:26:03 PM »
It fills me with regret to say that, for the first time in five years, I will not be participating in the GOF Awards. I simply have not been active enough over the past year to make any judgements on who I believe to be the most qualifying member for any of the rewards, and I would not consider it fair to anyone if I were to attempt to make those decisions based on my extremely limited personal interactions with other members, or a cursory review of the past year's forum activity made at the last minute.

Even though I will not be taking part in the award voting this year, I am very pleased to see that they are taking place as usual. I greatly enjoy and appreciate the GOF Awards, and dearly hope that my non-participation this year will not contribute to a lack of awards next year. Good luck to all members who are eligible for nomination, and thank you to all members who take part in the voting. :yes

The Party Room / What are you thinking about?
« on: August 24, 2014, 06:42:04 AM »
Wondering what it is about me that's so repellant to other people. :(

It seems to be my curse in life that no matter what social situation or relationship I find myself in, I either find myself stuck on the sidelines, feeling like an outsider with no place in the group; or, on the occasions when I try to take charge of my own social life and manage to heave myself into a position of acceptance, I unwittingly commit some social gaffe or expose some unidentified aspect of my personality that scares other people away, thus alienating myself from the person or social group I was attempting to interact with.

I can't understand what I'm doing wrong. Anyone who knows me should be aware of how quick I am to pontificate on my own flaws and deficiencies, but even with my rock-bottom level of self-esteem, I've long thought of myself (and strived to be) a friendly, easygoing, generous, courteous, patient, humble, moral, open-minded, non-judgmental person. So what am I doing wrong? Why is it that whenever I meet someone who shares my interests and to whom I express a desire to be friends with, they never return my e-mails or phone calls, or follow up on my appeals to communicate again sometime soon?

Keep in mind, these are all platonic relationships; I can't say I've never felt the slightest romantic or sexual interest towards anyone I've ever met. Could my problem be that I'm too friendly, too emotionally open, too quick to do generous things like pay for lunch or give a piece of artwork, that the people I try to befriend think I'm interested in them romantically? This is something I've often worried about, but at the same time I feel like it would make people uncomfortable if I were to put too fine a point on the fact that I am only looking for platonic friendships, or that I consider myself essentially asexual. Again, I feel like I'm doomed to failure at making friends, no matter which choices I make.

It's times like this when I feel like I'm beyond all hope of growing as a person; that my life's a dead end and that I'd be better off dying and sparing the rest of the world the inconvenience of having me around. My drive to accomplish things has all but withered away. Drawing and writing are slow, boring, agonizing processes for me now, and I take hardly any joy in them. Everything I do feels like an exercise in futility. Whenever I hear news about the world today (especially where wildlife and the environment are concerned), I grow ever more hopeful that I will not live long enough to witness the logical outcome of the events in question. Even my own ideas and ambitions for how I might potentially benefit the world look like impossible dreams with no chance of being fulfilled. I'm too slow, too eccentric, too forgetful, too inadequately skilled for this world. It's a depressing, lonely, pitiful thing to be me. :cry

General Land Before Time / A Theory about the Dinosaurs
« on: August 13, 2014, 10:31:09 AM »
Literal-minded as I am, when I first read your post, I assumed you were presenting this theory as a serious proposal of what The Land Before Time was intended to be. It only later occurred to me that you might have intended it as more of a playful "what if?" idea for the purpose of getting people thinking and provoking discussion, much like the content of the “Wild Mass Guessing” pages on TV Tropes. Am I correct in assuming that this is the case?

Just to be clear, I don't have a problem with people sharing WMG-type theories. (The way I see it, even proposing an idea that no one else buys into can be beneficial if it prompts people to evaluate and defend their established views and think outside the box.) Just to offer some constructive criticism, though, you might want to make it clear from the get-go when presenting a concept like this one that it is not about the creator-intended nature of the series in question, but more of a hypothetical alternative interpretation for your own headcanon. Otherwise you'll have a lot of people taking one look at your post (or even just the title, which, with all due respect, makes things even more confusing because it implies that your theory is that the LBT dinosaurs are mammals, not lizards), and either deciding that your theory (which they assume to be an "out-of-universe" explanation) is either too off-the-wall to be worth their time, or, after seeing someone like jansenov debunk all the points of the argument as they would apply to an "out-of-universe" theory, assume that the case is closed and that there is nothing more they can add. In either case, the reader may well avoid partaking in the discussion altogether. My point is that you're not asking, "Do you think maybe this is what LBT's creators really had in mind for their series?"; you're asking, "Do you think this reimagined version of the LBT universe I developed for my headcanon sounds feasible?", and I think it's important that the people who read your theory know that from the start.

I actually started writing a fairly long and elaborate response to your post last night, but it got too late (i.e., the sun started to come up :p), and I had to stop. By the time I was able to get back to writing the last 10% of my response, you had posted your follow-up and more or less confirmed my suspicions about this being an idea for your own headcanon, and much of what I had already written was rendered more or less irrelevant, as I had written them while I was still entertaining the possibility that your theory applied to the filmmakers' intentions for LBT. I hope this isn't inappropriate, but I decided to include most of this material anyway. Some of it might still be applicable, and at the very least, it provides insight into my initial reaction to this topic, which I think helps illustrate my point about why it helps to establish the context of a proposed theory right from the get-go.

Case in point, my original opening paragraph:

Unfortunately to say, I’m fairly certain that just about anyone on this forum who were to read this topic would have more or less the same conclusion: none of this argument holds water. The opening narration of pretty much every LBT movie explicitly establishes the setting as long before the time of humans, and the characters as dinosaurs.

First of all, the various species shown in the series never lived together in real life, neither geographically nor temporally.
The Mesozoic Melting Pot is one of the oldest and most ubiquitous tropes in portrayals of the prehistoric world. Most writers and filmmakers creating a story about prehistoric animals just can’t bear to limit themselves to the biodiversity that existed at just one time and place in the Mesozoic. (Truthfully I can’t really blame them; when presented with the full gamut of extraordinary creatures spread out across the fossil record like delicacies on a banquet table, it’s hard to pick just one plate and focus exclusively on it.) In almost all cases, they’ll find a way to showcase prehistoric animals from multiple periods, sometimes via a loophole (making their work an anthology, as in Walking With Dinosaurs, or bringing their cast of creatures to the present day, as in Jurassic Park), but more often by deciding, “To Hell with geochronological boundaries!” and mixing all their chosen prehistoric stars together in an anachronism stew.

For example, the length of time separating Stegosaurus from Triceratops is actually longer than the length of time separating Triceratops from modern humans. So showing a Stegosaurus with a Triceratops is even more inaccurate than showing a human with a Triceratops.
That statement about the time disparities is technically true (I've heard a very similar version of that quote multiple times before), but I feel inclined to point out that while Stegosaurus and Triceratops were separated by more geological time than Triceratops and humans, they were not separated by an extinction event that wiped out all known land animals larger than 25 pounds. So I would argue that depicting Stegosaurus surviving into the late Cretaceous would still be more plausible than depicting Triceratops surviving to the present day.

They are also anatomically inaccurate. For example, the tyrannosaurs are shown standing with their tail resting on the ground, like a kangaroo. This posture is now known to be inaccurate.
The original Land Before Time was made in the 1980s, when the paleontological epiphanies of the “Dinosaur Renaissance” were still struggling to work their way into mainstream educational media (and let’s face it: even a quarter century on, there’s still a disturbing prevalence of kangaroo-shaped tyrannosaurs and hadrosaurs, naked raptors with pronated “bunny hands”, elephant-footed sauropods, and leathery-skinned skeletal pterosaurs in pop culture depictions of dinosaurs.) Don Bluth’s designs were also clearly inspired by the paintings of classical paleoartists such as Charles R. Knight, Zdeněk Burian
Zdeněk Burian, and Rudolph F. Zallinger; magnificent, high-quality works well deserving of their pedestals in the paleoart hall of fame, but decades behind contemporary paleontological knowledge even then. So it should come as no surprise that the dinosaurs in LBT do not stand up to our current understanding of what dinosaurs looked like in life. (It does deserve applause, in my book, however, for being pretty much the only dinosaur movie ever to put fur on its pterosaursónamely Petrie with his neck ruff and the chirpy little black-and-white flyers that line up to meet Littlefoot at his birthósomething not even many educational films manage to get right.)

It has been said that global warming might make reptiles larger and more dominant. My theory is that, in the world of TLBT, global warming causes most of the mammals, including humans, to become extinct. After humans become extinct, the lizards take over as the dominant group of animals on Earth. Millions of years later, they evolve to look like dinosaurs. They also evolve the ability to communicate, like humans.
It’s not impossible that someday an extinction event will wipe out or severely impact mammals while giving reptiles the chance to flourish, but it’s probably not going to be anthropogenic global warming, if that’s what you’re talking about. While warm conditions are certainly very favorable to reptiles, they are not necessarily adverse to mammals. There are plenty of mammals living in hot climates, including tropical rainforests and deserts, ranging from rodents and bats to bears and ungulates. In fact, most of the major groups of placental mammals alive originated before or during the Eocene period, 10 million years after the Cretaceous extinction, when the global temperature suddenly and rapidly climbed as high or possibly higher than it was during the Mesozoic. Clearly mammals are adaptable enough that even if humans do not survive the inevitable mass extinction we are unwittingly instrumenting, it will probably not be the end for all mammals. I’m not sure what sort of environmental catastrophe could wipe out mammals while sparing the reptiles, and for the purposes of your theory (assuming you establish it as the “official” backstory for your version of the LBT universe), I would suggest you do some brainstorming until you settle on a more complex scenario for the disappearance of mammals. Or, just don’t specify what wiped them out. When in doubt, leave the details ambiguous. :p

It is certainly true that the lineage leading to lizards and the lineage leading to dinosaurs split from each other a considerably long time ago. However, that doesn't mean they couldn't evolve to be similar. For example, there was an animal called the thylacine that used to live in Australia until it became extinct in the 1930s. It looked amazingly similar to a wolf. In fact, anatomy students often have a difficult time telling the difference between the skull of a wolf and the skull of a thylacine. However, it is a marsupial, while the wolf is a placental mammal. The lineage leading to marsupials and the lineage leading to placentals split from each other at least 161 million years ago, but the wolf and the thylacine still look remarkably similar to each other. Given enough time, I don't see why a species of lizard couldn't evolve to look like a particular species of dinosaur.
It's not overly far-fetched that a lineage of lizards could evolve convergently with dinosaurs, resulting in certain forms that bear a close resemblance to actual dinosaurs. Ironically, T. rex and other large theropods were arguably incidental mimics of certain members of much older group of reptiles from the Triassic period, the pseudosuchians. More closely related to crocodiles than to dinosaurs (though they were still archosaurs), this group included a number of large predatory species such as Poposaurus, Postosuchus, and Arizonasaurus (which gets bonus points for resembling Dimetrodon[among the apex top predators of their respective ecosystems, but are now suspected by paleontologists to have been bipedal. Much like your thylacine example, the skulls of these reptiles were so theropod-like that virtually any layperson shown a picture of one would almost surely identify it as a T. rex. There were other Triassic pseudosuchians, too, that bore striking similarities to some of the dinosaurs that succeeded them: the beaked Shuvosaurus[/U] was actually thought to be an unusally ancient ornithomimosaur until a more complete specimen of a close relative, Effigia, was discovered (they look even more like Limusaurus, a bizarre toothless ceratosaur from the late Jurassic of China). And some might argue that the aetosaurs (including Desmatosuchus and Typothorax), low-slung armored herbivores, looked a bit like clubless-tailed ankylosaurs such as Nodosaurus and Gastonia (though I, and I’m pretty sure most paleontologists as wellówould be more apt to compare them to a cross between a crocodile and an armadillo).

Even with all these real-life examples of convergent evolution between dinosaurs and other reptiles, one aspect of the theory that seems unlikely to me is that these hypothetical future lizards would evolve to inadvertently replicate the exact diversity of dinosaurs seen in The Land Before Time (along with pterosaur-mimics, plesiosaur-mimics, and repetitions of the various other non-dinosaur species that appear in LBT) while at the same time not producing any forms that look noticeably unlike anything seen in the series. To put it another way, while a thylacine could be conceivably mistaken for a wolf (disregarding the more subtle aspects of its physiology that define it as a distinctly different animal), many of the species that shared its environment, such as wombats, platypuses, and pademelons, have no such evolutionary doppelg‰ngers in other parts of the world. A future Earth inhabited by squamate-descended dinosaur facsimiles would surely contain many other, much less familiar-looking organisms, a red flag to the fact that this is not the Mesozoic era, not even a melting pot version.

The variables involved in evolution are virtually infinite, and in order to really closely resemble the original dinosaurs (or even LBT’s versions of them), lizards would have to stumble upon many of the same evolutionary adaptations that the dinosaurs developed, or at least equivalent adaptations that served the same functions and allowed for similar evolutionary flexibility. For example, dinosaurs were able to walk with their hindlimbs permanently upright because the head of the femur fit into a sideways-facing hip socket, whereas pseudosuchians like Postosuchus had “pillar-erect” hindlimbs, with a shelf of bone at the top of the hip and a downward-facing hip socket (see diagram). The dinosaurian hip socket was also backed by cartilage rather than bone, which may have allowed the legs to move more smoothly. It’s not clear whether this adaptation has anything to do with the fact that dinosaurs survived the extinction event at the end of the Triassic while most pseudosuchians apart from crocodylomorphs became extinct.

One could also argue that lizards would never evolve to closely resemble the LBT dinosaurs, because the bodies of the dinosaurs in the series are biologically unfeasible, and so it would be unlikely for any species to adapt them. For example, the kangaroo-like upright posture of the bipedal dinosaurs in LBT is inaccurate because it is simply nonsensical: the function of the long, heavy tail in dinosaurs was to counterbalance the body (reptile tails also contain muscles that attach to the femur and provide extra leg power); in fact, the vertebrae and tendons in most dinosaur tails were arranged in such a way that the tail wouldn't droop, with most of the flexibility being in the horizontal plane. Allowing the tail to droop all the way to the ground and weigh the back half of the body down, with the head and neck held so high up that the animal would be required to practically perform a headstand every time it needed to take a drink or pick up a piece of food on the ground, seems positively biologically illogical. Kangaroos have the excuse that they use their tail as a fifth limb (literally; studies have found that, when walking on all fours, a kangaroo's tail contributes more mechanical work than the rest of its limbs combined), and as a prop when they rear back and kick with their hind legs. The LBT dinosaurs are never shown doing this, and I’m not sure it would even be biomechanically feasible for such large animals. To say nothing of why a large terrestrial animal would forgo a perfectly good counterbalancing appendage in favor of subjecting itself to perpetual caudal rugburn.

Admittedly, there are a couple of caveats with this issue. Firstly, if I know one thing about natural selection, it’s that it’s more than capable of generating adaptations so bizarre, complex, ungainly, or impractical in appearance to human eyes, that if we didn’t know they existed, not even the most creative human mind could have ever conceived them, let alone the evolutionary processes that led to them. (Seriously, could you imagine a creature that eats its way out of an egg; grows to 2,000 times its birth weight in less than two weeks; casts off the entire exterior of its body to become a featureless, leaflike pod; which later splits open, birthing a bloated creature that immediately redistributes its bodily fluids to inflate a set of wings so it can fly to the other side of a continent to sleep; if you had never heard of butterflies?) Maybe there is a biologically feasible evolutionary path that would lead to an enormous, upright-walking, droopy-tailed reptilian biped; I just can’t think of one. Secondly, I’ve noticed that, compared to the sequels, the bipedal dinosaurs in the original LBT are a lot better at keeping their spines in a realistic horizontal posture while walking, and both the bipeds and quadrupeds spend a lot more time with their tails held high off the ground (probably due to Bluth and co., making a stronger effort to maintain an element of realism in their dinosaurs than the makers of the sequels). So if you envisioned all the characters in your version of the LBT universe as being more like the dinosaurs in the first movie, you might be able to bypass the issue of improbably-kangaroo-shaped dinosaurs at least.

In any event, your scenario is a big fat honking heck of a lot more likely than the agonizingly ubiquitous clichÈ in science fiction of the evolutionary processes on different planets independently churning out species that look more or less identical to humans :rolleyes (made even worse when said humanoid species are depicted as being able to interbreed with one another :slap), or the idea that a humanoid species could “seed” a planet with genetic material destined to eventually replicate the body plan of its progenitor (as seen in the movie Prometheus). If you could see yourself creating a story or headcanon involving aliens with little or no qualms about scientific adherence, then your idea for dinosaur-mimicking future lizards is hardly worth fussing over.

Incidentally, a British paleontologist named Darren Naish has already imagined a speculative alternate Cenozoic in which lizards and snakes became the dominant large animals following the Cretaceous extinction: the Squamozoic era.

Global warming may or may not pressure lizards to develop in such a way. Mammals rapidly evolved during the Paleogene thermal maximum while lizards remained small animals, for example. There must be other factors involved.
Actually, it’s been recently discovered that that there were large lizards living alongside mammals during the Paleocene and Eocene epochs. The impressively named Barbaturex morrisoni (“[Jim] Morrison’s Bearded King”), from the Eocene of Myanmar, was at least three feet (1 meter) long not counting the tail, with an estimated mean body weight of almost 60 pounds (26.7 kilograms), ranking it among the larger animals in its habitat; which included a diverse assortment of primates, ungulates, and carnivorous mammals. This was a large reptile that clearly did quite well for itself despite being surrounded by potential mammalian competitors, casting doubt on the conventional wisdom that large herbivorous reptiles cannot evolve alongside herbivorous mammals because mammals supposedly always outcompete reptiles attempting to share the same niche. :rolleyes

And an increase in lizard intelligence is likely, since their fellow amniotes, the mammals and dinosaurs, also show an increase in brain size and complexity over time. However, lizards and crocodiles have not developed their brains nearly as fast as the above two until now, so they may take more time to get to their level.
This is going a bit off-topic, but there is a bastion of zoological dogma that desperately needs to be demolished, and that’s that reptiles are primitive, unsophisticated creatures possessed of limited intellect and with minimal capacity for social behavior. In the last several years, however, it is becoming increasingly apparent that this is absolute bunk. Far from simpleminded submarine bear-traps, crocodilians are now recognized as perceptive, flexible hunters that learn the favorite watering locations and even the habits of their prey, from migrating fish to humans washing at the riverbank. Moreover, American alligators and Indian mugger crocodiles have recently been discovered to lurk beneath heron and egret rookeries with sticks (a much-sought-after resource for the nesting birds) balanced across their snouts, enticing the birds within striking range.

Reptiles have been found to have problem-solving skills, too. An experiment with a red-footed tortoise given eight chances to collect eight treats, one at each end of an eight-spoked radial-arm maze (i.e., collect every treat without taking the same path twice), found that the tortoise used objects visible beyond the maze as landmarks to keep track of its progress, and when those were obscured, modified its behavior, systematically entering each arm of the maze adjacent to the one before it in turn (a strategy that not even all mammals are apparently able to replicate). Another experiment found that tortoises can learn to solve a problem they can’t figure out by themselves if they watch another tortoise complete the same task (in this case, taking a long detour around a wire fence separating them from a piece of fruit); in other words, they are capable of social learning.

On the subject of social behavior, shingleback skinks, while solitary for most of the year, have been found to form monogamous pair bonds, seeking out the same mate year after year for as long as two decades. Some pythons actively incubate their eggs by first raising their own body temperature through sunbathing and then coiling around the clutch. Mother caimans “adopt” the offspring of other females, which congregate in a single massive crËche guarded by a single female, who guards them against predators and leads them to new sources of water if the pool dries up. (The sheer number of hatchlings increases the odds that the “babysitting” mother’s own offspring will not be taken by predators, while the other adult females are free to disperse, allowing for less competition between them.)

Many reptiles have even been recorded engaging in play behavior in captivity, such as the case of a Nile softshell turtle that formed a habit of engaging in self-mutilation behavior (a common response to lack of enrichment among animals in captivity), which decreased after it was provided with toys such as basketballs and hoops of hose, which it would manipulate with its mouth in various ways or push around its enclosure. There was also a well-studied Komodo dragon who not only played with shovels, blankets, boxes, and other objects placed in her enclosure, but play tug-of-war with her keepers, pull hendkerchiefs and notebooks from their pockets, and yanking or nipping off their shoelaces (all while distinctly not treating the objects in question as food).

As more and more of these behaviors come to light, the more likely it appears that the traditional view of reptiles as unintelligent and asocial was based more on limited research and flawed lab studies biased towards mammalian behavior and living conditions than actual evidence. That prejudiced mindset subsequently became so deeply ingrained in scientific doctrine that reptiles were largely ignored in further studies of animal intelligence and social behavior, and herpetologists were trained to believe that such behavior in reptiles didn’t exist, so they seldom if ever thought to watch for it. Now that researchers are starting to give reptiles their due, it is becoming increasingly apparent that big-brained birds and mammals are not as special as we once thought they were.

Sorry for the ridiculously belated response, but I decided my mind would never be at ease unless I posted this.

I just wanted to thank you, Pterano and MurMur, for your star day greetings. I tremendously appreciate any and all birthday well-wishings, no matter how late they are. I am so utterly lonely and lacking in confidence these days that any gesture of friendship or good will offered to me is a much-savored treat. Thanks so much to you and everyone else who wished me a happy birthday. :)

Oh, for those of you who haven't seen them, I have now posted photos of me wearing the lobster hat and other quirky marine-life-themed accessories in the "Show us a picture of yourself" thread. Good place to go if you need a laugh. :lol

Aww, thank you all so much! :DD Really, it means a lot to me that you thought to wish me a happy birthday. :^.^:

My youngest brother and our cat Sasquatch are the only members of my family at home right now, and my brother had a summer art class that would keep him away for the morning, so I spent the first half of the day at the local aquarium, where I volunteer as an exhibit interpreter, where I could both enjoy myself sharing facts about the animals on exhibit, and receive birthday greetings from my friends on the aquarium staff. Oh, and in honor of the occasion and the setting, I spent the whole time wearing a lobster on my head :lol (a plush hat I had bought as a souvenir in Boston once), which was in turn wearing a dinosaur party hat I had dug out of a cupboard (an unused leftover from a dinosaur-themed party our family had held years ago). I received a great many amused grins and strange looks from visitors, and the aquarium staff loved it. Upon telling my supervisor my plans for the day, and informing her that I had not yet decided which local restaurant to visit for my birthday sunch (supper/lunch), she made the perfect recommendation: Red Lobster. I was, of course, bamboozled that I had not thought of that myself (especially after one or two other staff members later made the same suggestion). So after my brother came to meet up with me after finishing his class, that's where we went, the lobster hat (and its hat) still on my head. We had an excellent meal, made even better by the fact that literally everyone we met who was working at the restaurant that day completely loved the hat. My brother and I had planned to hit the nearby movie theater to (re)watch How To Train Your Dragon 2, but our lunch ran a bit long, so we just headed straight home, where we baked a triple-layer dark chocolate fudge cake with chocolate frosting and toasted marshmallow inter-layer filling (modified from a recipe I had found online). Due to the complexity of the recipe and the fact that I took a nap that afternoon due to being incredibly tired, we didn't get around to lighting candles and eating the cake until about 9 PM. Our mom and sister (each of whom had also called earlier to wish me a happy birthday) joined us via speakerphone to sing "Happy Birthday" (the most off-key rendition I think ever heard in our family, :p due to all three participating singers being in separate parts of the U.S. and thus having difficulty keeping their voices synchronized). The cake was very tasty, though I don't think the chocolate was quite rich enough to match the sweetness of the marshmallow filling. Afterwards, my brother gave me a spectacular hand-drawn birthday card, and I responded to e-mails sent from the respective iPhones of my dad and older younger brother (both of whom are in China right now and could therefore not communicate by other means).

Again, thank you, rhombus, bushwhacked, Ducky123, Kor, Chiletrek, Iris, jansenov, Malte, vonboy, and Chronicler, for the star day greetings. I really appreciate it. :) :smile

Quote from: Ptyra,Oct 8 2013 on  12:20 AM
So of course I have three Dalek storylines running around in my head, two developing more and more as I work on it.

There's one that I'm struggling with on a scientific standpoint. I have extended my work on the Daleks residing in New Skaro. In the last link I posted, you will see a discussion I had based on their reproductive biology...mainly the fact that they have eight genders.
My idea was that this was because their started as gonad-less androgenites (...yeah, I made that word up), and had to work up to having two separate genders.
It goes:
Androgynous - Gametes can mix with any other indiscriminately
Hermaphrodite - Masculine, feminine, and neutral
Male and female - There are also 'feminine males' and 'masculine females'...basically the same as seahorses.

My math is probably completely wrong, but there are 64 potential pairing mixes here, with only nine NOT resulting in offspring. Or less...since a masculine male and a masculine female technically can have their gametes mixed, it would just be a very difficult process...and I'm not really sure how it would get done.

One factor to keep in mind is that while they are socially monogamous, taking only one partner for a lifetime, they are sexually polygamous. For similar reasons to several species on earth. One sole partner to share a life and home with, but with short stands mixed in to propagate the species.

The person I was talking with stated that eight genders seems a bit complicated and senseless. And it's already clearly confusing as it is.

But with you as an 'armchair biologist', as you once called yourself...is there a way to make sense of it? With the New Skarorean Daleks having a fairly small population (at least compared to the Daleks during the Time War), how would having eight genders work?

I really need to write down their complicated social lives and gender structure...it's a mess.
Wow, this is a hard one. :blink: Though it’s no excuse for me taking so long to respond to this thread (my apologies for that :bang), part of the reason was that I honestly wasn’t sure how to respond to it. I don’t know of any species in nature with a system of sexes or genders* like what you described, and my first thought was that it would be incredibly unlikely for something like that to ever evolve. But then again, I am inconceivably, incalcuably far from knowing everything about the natural world, and if there’s one thing I’ve learned, it’s to never underestimate the ingenuity and complexity of evolution.

*For the purposes of this discussion, I will be using the term “gender” to describe distinct morphological and behavioral phenotypes within sexes of a species, ignoring the human social and cultural application of the term.

I wasn’t sure where to look for more information on the subject. I checked the “Real Life” section on the TV Tropes page for
”Bizarre Alien Sexes”
”Bizarre Alien Sexes”, which had a few examples of real-life organisms in which the division of sexes is different from what we humans are familiar with, including a species of nematode worm (Caenorhabditis elegans) in which individuals are either male or hermaphrodite, and the white-throated sparrow (Zonotrichia albicollis), which may be in the process of evolving a second set of sex chromosomes. The sparrows come in two color morphs: one with a black-and-white-striped head, the males and females of which tend to be flamboyant, aggressive, promiscuous, and participate little in the raising of young; the other with a brown-and-tan-striped head, in which males and females tend to be milder-mannered, more loyal to their mates, and care intensively for their offspring. However, these sparrows (which, by the way, are socially monogamous) virtually never choose mates of the same color morph; white-striped females almost always mate with tan-striped males, and tan-striped females with white-striped males. With the two color morphs unlikely to diverge into separate species anytime soon, these birds effectively have four genders. (See the list of sources at the bottom of this response for the article on the subject.)

The sparrows made me think of another bird with an unusually complex breeding system. The ruff (Philomachus pugnax) is a species of sandpiper in which there are three genetically distinct male morphs. The first is the territorial male, which, during the breeding season, sports a homegrown Elizabethan collar of (typically) dark plumes on his head and neck (the “ruff” for which the bird is named). These males form leksócongregations in which each individual displays on a shared courtship arenaóeach defending his own mating court while the females take their pick of mates. The second is the satellite male, which also develops a neck ruff, but one that is lighter in color than the territorial males’. Instead of holding their own territories, these males wander the leks in search of mating opportunities: younger, lower ranking satellites “steal” mating opportunities from territorial males, while older, higher-ranking individuals are apparently actively “recruited” by territorial males to stay on their courts, as females are evidently more likely to visit a court where satellite males are present. The third and rarest form of male ruff is the faeder, or cryptic male, which never develops a neck ruff and resembles a female in plumage and size (though it is thought that this form actually represents the ancestral male ruff courtship plumage prior to the evolution of the other two male variants and their elaborate collars). Like the satellites, these males move through the leks in search of females, their feminine appearance perhaps allowing them to get close to females without the ruffed males driving them off, but interestingly, faeders often end up coupling with other males as well. Moreover, these males seem to know that the faeders are not females, because whereas the female ruff is always mounted by the male during mating, the faeder is just as likely to be the one “on top” as the other male during these pairings. Apparently, female ruffs are excited by male-on-male couplings, and male ruffs (both territorials and satellites) who learn to recognize faeders deliberately engage in this behavior as a ploy to draw female attention. (I wonder if this means we can add yaoi to the list of supposedly human innovations that other species beat us to. :p)

If your concept is that the Daleks are initially unable to reproduce on their own (and omitting asexual reproduction as a possible option for the time being), and have to “invent” a means of doing so, I think the most logical first step would be isogamy (pronounced “eye-SOG-uh-mee”). Isogamous organisms reproduce sexually, but there are no males or females; if there are gametes involved, they are undifferentiated. Instead of a tiny, motile sperm and a large, energy-stocked egg, you might have two identical-looking gametes that fuse to form a zygote. The parents themselves might be undifferentiated, but it’s also possible for them to have unique characteristics. According to some sources I’ve seen, at some species of fungi are considered to have literally thousands of sexes, most of them compatible with one another (though only two are needed for reproduction at any one time).

There’s another form of isogamy that doesn’t involve gametes at all. It’s called conjugation, and it’s used by bacteria, fungi, algae, and ciliate protozoans such as Paramecium to transfer genes laterally from one individual to another. For example, bacteria deploy hollow structures called conjugation pili to inject DNA directly into other bacteria. For example, an individual of Escherischia coli with a gene that enables it to digest lactose can stab another bacterium (not even necessarily another E. coli) with a conjugation pilus and inject it with that gene, and that bacterium will be able to digest lactose. Furthermore, when that bacterium divides, its descendents will all receive copies of that gene. And if the E. coli also transferred the gene that allows a bacterium to form conjugation pili, then the recipient (and all its descendents) will be able to grow its own pili and pass genes on to other bacteria.

Assuming the Daleks in your headcanon do not start out as identical clones (in which case individuals would have no unique genes to bother transferring), perhaps they could start out using conjugation to swap desirable genetic traits with one another (Actually, it would seem that Daleks are already capable of conjugation, based on the one that stole Rose’s DNA in “Dalek”, even if it only intended to absorb the artron energy she had picked up through time travel.) Once they figure out how to engineer themselves to produce gametes, they could become a race of isogamous “androgenites”, with no sexual differentiation. From there, it would only be a matter of engineering separate strains with unique biological features and reproductive compatibilities, leading to an assortment of sexes/genders consisting of various combinations of male, female, masculine, and feminine traits. I’m not sure why they would devise such an elaborate system, but then, the Daleks are all about large-scale experimentation. Having achieved the capacity for sexual reproduction (presumably as a means of more efficiently propagating their species), perhaps they decided to try every conceivable version of it, to find out which method worked the best. Either they decided that every method was advantageous enough to keep, or the experiment is still in progress.

Sorry again for taking so long to actually come up with anything in response to your question. I hope this is helpful, at least, and I’d be happy to discuss it with you further. It’s really a very interesting subject. :yes

If I remember correctly, you've said that you like the show My Little Pony: Friendship is Magic. I'd like to ask a hypothetical question: If the Mane 6 watched MythBusters, what do you think their favorite myths would be? (I already have a good idea myself, but I'd like to wait and see what you have in mind before revealing my picks. :p )
Yes, indeed, I do like the show :yes (though, like LBT, I haven't watched it for a while now). And MythBusters + MLP:FiM is a formula that I've personally always thought of as fun. :p

I should note that, at this point, I have not yet watched Season 4 of MLP, so I am not privy to any new insights into the personalities of the characters that might influence my guesses as to which myths I think they’d enjoy. Also, with my choppy memory and the hundreds of myths the MythBusters have covered, I’m bound to come up with other ideas of myths the MLP characters might like that I hadn’t thought of at the time I posted this. Just thought I’d mention that.

I imagine Rainbow Dash’s favorite myths would generally fall into the category of “things moving fast and stuff blowing up”, so she’d probably enjoy myths like “Jato Rocket Car” (particularly the 10th anniversary revisit), “Torpedo Tastic”, “Water Heater Rocket”, and anything involving the New Mexico Tech rocket sled (e.g., the “Compact Compact” and “Snowplow Split” revisits). “Sonic Boom” might also pique her interest, if only because it involved creating sonic booms with the help of the Blue Angels (who are pretty much the Earthly equivalent of the Wonderbolts). EDIT: Oh, and “Beat the Speed Camera”; she’d definitely love that one.

EDIT: Completely forgot an obvious choice for one of Rainbow Dash’s top favorite myths that completely slipped my mind: “Beat the Speed Camera” (and its revisit).

Fluttershy would almost surely have a preference for animal myths, such as “Duck Quack”, “Skunk Cleaning”, “Bull in a China Shop”, “Teaching an Old Dog New Tricks”, and “Herding Cats”.

There’s a lot of myths I’m sure Pinkie Pie would love, but I think she’d be particularly fond of the flashy, quirky, cartoony ones, such as “Painting with Explosives”, “Carried Away” (via a massive bunch of party balloons), “Border Slingshot”, “360? Swingset” “Waterslide Wipeout”, “Diet Coke and Mentos”, “Square Wheels”, “Exploding Pants”, “Invisible Water”, “Bottle Rocket Blast-Off”, “Gunpowder Trail”, and “Party Balloon Pile-Up” (assuming she doesn’t have a problem with the fact that the clown would have died no matter what version of a party balloon airbag was used).

I can see Applejack enjoying a wide variety of myths, though I imagine she’d particularly like the ones that provide practical information, such as “Fire Without Matches”, “Walk a Straight Line” (though I’m not sure it applies the same to equines as it does to humans), “Slap Some Sense”, :lol and the duct tape myths (do they have duct tape in Equestria?). For some reason I think she’d also get a laugh out of the myths regarding idioms and proverbs, such as  “Finding a needle in a haystack”, “Does a rolling stone gather no moss?”, and “Can’t teach an old dog new tricks”. Given her love of competition and rodeos, myths like “Row Boat Water Skiier”, “Pants on Fire” (starring Pistol, the psychic stunt horse :lol), “Red Flag to a Bull”, and “Greased Pig” might also be favorites. Finally, I would cautiously posit that Applejack would enjoy “Talking to Plants”. (I suspect she’d appreciate knowing that all the talking and singing she does to her apple trees has some scientific grounding, :p though then again she’d probably be indignant at the conclusion that it doesn’t matter what you actually say to them.)

Rarity is a tricky one; compared to the rest of the ponies, I have a hard time envisioning her deriving entertainment from the MythBusters’ typical routine of shooting, exploding, and otherwise destroying things (including their own creations), and generally making a spectacular mess. Still, if she can appreciate sonic rainbooms and death-defying stunts by Rainbow Dash, I don’t think it’s impossible that there would be a MythBusters episode or two she’d like. I can imagine her enjoying stories like “Breaking Glass”, “Voice Flame Extinguisher”, and “Let There Be Light”, as they have a certain elegant, artistic quality to them that I think might hold an attraction for Rarity. I also consider it possible that some of the high-speed shots of certain explosions might appeal to her (“Trench Torpedo”, “22,000 Foot Fall”, the lava lamps in “Exploding Lava Lamp”, the spray can in “Hot Bullets”, and the “Painting With Explosives” revisit being a few possible examples); they have an aesthetic quality that I certainly love.

As the most scientifically minded character, I think Twilight would like the myths involving physics thought experiments, such as “Bullet Fired Vs. Bullet Dropped” and “Vector Vengeance” (if you fire an object from the back of a moving vehicle at the same speed said vehicle is moving, does it simply drop to the ground?). I think she would also enjoy “Sounds Bogus” (movie sound effects vs. the real world) and the “NASA Moon Landing” episode. Her favorite myth might be “Archimedes Death Ray”, specifically the “President’s Challenge” revisit, because it so epitomizes the process of learning through scientific experimentation. (I personally consider Jamie’s speech at the end of that episode to be one of the finest in MythBusters’ history.)

Bonus character: I can easily envision Spike as a huge fan of the flashier elements of MythBusters, namely fire and explosions. “Fire Dragon” (surprise, surprise :p), “Hwacha”, “Rocket Man”, “Fireworks Man”, and “RED Bazooka” would be among his top faves. Also “Diet Coke and Mentos” and the experiments that the “Do try this at home?” episode concluded were safe to try at home, because he would see fit to try them out for himself. :lol

It's good to hear from you. :yes What made you break the silence?
Well, I hope this explanation doesn't sound as petty as I fear it does, :unsure: but honestly the biggest reason was because of my 5th anniversary as an active GOF member. Anniversaries, milestones, and events or objects that mark some sort of achievement or turning point hold a very special significance to me. Although I don't post so much on the GOF anymore (and I no longer feel like I have much of a role here or anything to contribute), the forum has affected my life immensely, and I have a lot to thank it for. I felt obliged to acknowledge that, so I made a point of posting that day. Also, my post count at the time was 4,391, so I decided, why not bump it up to 4,400 and make my big anniversary post honoring the GOF even more special? (Big round commemorative numbers are also significant to me.) Besides, it gave me the motivation to have a bit of fun posting in a bunch of random threads (most of them humor-oriented).

I'd certainly like to engage in more social interaction on here (I'm awfully lonely these days), but most of the members I was once friendly with don't seem to be around much anymore, and I'm not sure how to get back into the habit of posting or where I can contribute to the forum. (I think I've had a relapse of shyness, self-consciousness, and social awkwardness.) I'm sorry that the few posts I've made on this forum recently haven't been more substantial or contributive, and that they didn't signify a true return to regular posting. :oops It's comforting to hear that you and the other members who posted in my five-year anniversary thread were glad to see me back, at least. :)
