Oh, and Dr. Lou, sorry, I don't know too much about t-rex. You see, I grew up in a grassroots household, the type that encouraged the throwing-of-rocks at black people, the beating-up-of gay people, the idea that t-rex was a carnivore, and the undying support for the republican party. (heheh not really)Please Register or Log in to view the hidden image! Alright, what about Allasaurus (possibly spelt incorrectly)? A-saurus was pretty big, although not the size of the t-rex. Was he a scavenger too? Where do you draw the line? Also, I think that your argument on rex falling over is incorrect, in that he would have had really tough bones because of his size. I think he was fairly succesful, he was around until the dinos were wiped out, so I guess that's the best that his species could have asked for. I simply cannot believe that a scavenger could get that big. That's my main problem with that argument, there's just no reason. Scavengers are small. Some carnivores are too, but some are not.
