Tyrannosaurus Rex

One of the largest dinosaurs that ever lived, Tyrannosaurus rex was a fierce carnivore. Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite. Fossils of T. rex prey, including Triceratops and Edmontosaurus, suggest Tyrannosaurus crushed and broke bones as it ate.
