Ceratosaurus was a large predatory theropod dinosaur from the Late Jurassic Period found in the Morrison Formation of North America, and the Lourinhã Formation of Portugal. It was characterized by large jaws with blade-like teeth, a large, blade-like horn on the snout and a pair of hornlets over the eyes. The forelimbs were powerfully built but very short. The bones of the sacrum were fused (synsacrum) and the pelvic bones were fused together and to this structure (Sereno 1997) (i.e. similar to modern birds). A row of small osteoderms was present down the middle of the back.

Ceratosaurus vs Stegosaurus

In the late Jurassic segment, 3 Dryosaurus look for water but fail to find any. Suddenly, a Ceratosaurus comes out of ambush and attacks the Dryosaurus. The Ceratosaurus catches the slowest youngster. The  remaining Dryosaurushide under a CamarasaurusLater, a male Stegosaurus meets a female and tries to show off. Then the Ceratosaurus comes out of nowhere but the male's tail spikes hurt the predator. The Ceratosaurus walks off in defeat. Later, a much larger Allosaurus then attacks and kills the Ceratosaurus who is trying to hunt the Dryosaurus again. 

Errors Edit
