allosaurus: specialized or genarlaized

Generlaized, though when the climate changed quickly, even Allosaurus was doomed.

i wonder why

No clue except that's what the fossil record tells us

Generalized, I think if the climate didn't change so suddenly it would probably be around to the late cretaceous. That's my opinion considering their speed, agility, and the huge population of allosaurus in the world. They are one of the most successful dinosaurs ever to exist.

Well, there were maastrichian(think i spelled that right) allosaurids, A.Fragilis barely made it until the jurassic-cretaceous boundary.

It was a generalized theropod, although it posessed several traits that would have lent a hand in killing the sauropods of its era. Climate change, my friends, is a bitch. It kills off animals that, unfortunately just weren't quite ready for that change.
