Ceratosaurus - Meaning: Horned Lizard

Ceratosaurus (Keh-RAT-oh-sore-us) was a large predatory dinosaur from the Late Jurassic Period, found in the North America, in Tanzania and possibly in Portugal. It was characterized by large jaws with enormous, bladelike teeth, a large, blade-like horn on the snout and a pair hornlets over the eyes.

The forelimbs were powerfully built but very short. The bones of the sacrum were fused and the pelvic bones were fused together and to this structure (i.e. similar to modern birds). Evidence suggests that there may also have been a row of small spurs or even a low sail, along the spine. Very scant remains of a Ceratosaurus-like theropod have been found in Tanzania and would have belonged to an animal at least 15 metres (50 feet) in length, much larger than Allosaurus.

Ceratosaurus was a herbivourous dinosaur.
