I liked that scene from JP3. It's actually my fav of the whole movie.
I watched a program the other day, where Jack Horner and someone else were debating whether or not Tyrannosaurus was hunter or scavenger, a warrior or a wimp. But in the end, the two sides have joined together, and they conclude that T-Rex was both hunter and scavenger, that he wasn't a warrior or a wimp, but one of the most magnificent animals ever to walk the earth.
While his arms couldn't do him any good, why not his feet? After all, modern day birds like the bald eagle and owl can use their feet to deliver painful wounds and such. So why not T-Rex?
I also saw a program that talked about Tyrannosaurus Rex's rise to fame and how fast it fell when rumors came in stating he was a scavenger. It was Steven Spielberg who saved him from being forgotten by putting him into Jurassic Park as a predator.
I also saw Dinosaur Face-Off, where scientists analyze possible data for dinosaurs, and through tests and experiments, discover some truth behind them. This is the program that found evidence for T-Rex being able to hunt. In this program, I learned that Tyrannosaurus not only had a great sense of smell, but also terrific sight, vision field (wolf-like), and he could bite down with the devastating force of 3-4 tons, and rip out 4 pounds of flesh. o_o He could easily rip apart a family car.
