Sep. 25, 2019 — A Tyrannosaurus rex could bite hard enough to shatter the bones of its prey. But how it accomplished this feat without breaking its own skull bones has baffled paleontologists.
This group of huge carnivores ruled the land during the Cretaceous period. Short but deep jaws, long hind limbs (legs), beady eyes, a long muscular tail, and tiny forelimbs (arms) make up a tyrannosaur. The Tyrannosauridae included such similar animals as Albertosaurus, Gorgosaurus, Daspletosaurus, Tarbosaurus, and of course Tyrannosaurus Rex.
