It was the size of a typical large predatory dinosaur--as long as a large Tyrannosaurus rex and as heavy as the top Jurassic predator, Allosaurus
But the stars of "Walking With Dinosaurs -- The Live Experience," those life-size replicas of the plateosaurus, liliensternus, stegosaurus, allosaurus
, ornithocheirus, brachiosaurus, torosaurus, ankylosaurus, Utahraptor and Tyrannosaurus rex, come with an abundance of attitude
They think it looked like Allosaurus
(AL-uh-SAW-rus), which lived in North America.
