The name says it all. This group of huge carnivores must have tyrannically ruled the land during the last part of the Cretaceous, 85 to 65 million years ago. Short but deep jaws with banana-sized sharp teeth, long hind limbs, small beady eyes, and tiny forelimbs (arms) typify a tyrannosaur. The Tyrannosauridae included such similar animals (in rough order of increasing size) as Albertosaurus, Gorgosaurus, Daspletosaurus, Tarbosaurus, and of course Tyrannosaurus rex. A tremendous skeleton of Tyrannosaurus now stands guard in the Valley Life Sciences Building, which houses the UCMP and the Department of Integrative Biology at UC Berkeley. Tyrannosaurs belong to the Saurischia, or "reptile-hipped" dinosaurs. Within the Saurischia, tyrannosaurids belong to the group of carnivorous dinosaurs known as theropods. Traditionally, the tyrannosaurs have been included within the Carnosauria. In this classification scheme, carnosaurs represent the largest carnivorous animals to ever walk the land.
Tyrannosaurs are surprisingly common in many North American fossil beds, especially their large, serrated teeth, which they shed periodically like most archosaurs.
