Sharptooth is dead and gone.....
I think Ozzy and Strut got away and is probably looking for eggs elsewhere.
Ichy and Dil probably reunited. I find it hard to believe that a plesiosaur could actually kill a Deinosuchus. And the duo always had their fights throughout the whole movie and got back together. So it seems reasonable that the same applies here.
The Plated Sharptooth in movie 5 seems to have been washed away towards the mainland. So on the chance he wasn't attacked and eaten by the Megalodon, he might've swam ashore and is now living somewhere on the mainland.
Those poor sharpteeth in movie 6 are dead.
Sierra and Rinkus lived and are probably healing somewhere. I read a few times that Sierra was meant to appear in movie 12, but he was cut...unfortunately... (Anyone who knows me knows that Sierra is my ultimate fave character). Also, I wouldn't call them 'idiots'. Sierra seems a bit short in the brains department, but I wouldn't call him an idiot. And Rinkus was far from an idiot. He conned Pterano and the audience into thinking he was stupid coward, but revealed his true intentions when he revealed his conspiracy plan against Pterano. I think Rinkus knew exactly what he was doing the whole time and I would have no doubt he and Sierra woud've come out victorious if the rock did have it's special 'powers'.
The sharptooth in movie 8 is either dead or is in a coma like what happens to a lot of the other sharpteeth that falls off cliffs.
The Liopleurodon is living very happily as the top ocean predator!! I love Liopleurodon sooooooooo much!! It's so MAGICAL!!
The sharpteeth in movie 10 are off somewhere regretting being so terrified of a harmless eclipse
The 2 Fast biters in movie 11 are also off somewhere, doing whatever it is raptors do when they're embarrassed of their overly ticklish nature....
The sharptooth in movie 12 probably figured out that all he had to do to free himself is to back up and now he's living somewhere.
In movie 13..... I never watched that movie....And I plan to keep it that way...
And Redclaw, Screech, and Thud are doing their own thing.
