Dinosaurs

Ceratosaurs

Eoraptor

One of the earliest known dinosaurs, Eoraptor was a carnivore. It was smaller and more lightly built than its relative Herrerasaurus. Its teeth were sharp and slightly serrated for cutting through meat, but it did not have the flexible jaw joint of Herrerasaurus.

​

Herrerasaurus

Like Eoraptor, Herrerasaurus was one of the earliest known dinosaurs. It would have moved upright on its legs, which were more than twice the length of its arms. Its Fingers were strong and had large curved claws for grasping prey. Sliding joints in the lower jaws allowed for more flexibility when biting.
