JFC Ceratosaurus
Ceratosaurus was a medium sized carnivorous dinosaur with a unique horn protruding out of the end of its skull. It was one of the earliest dominant predators. Named by Othneil Charles Marsh in 1884 it could grow up to 22 feet (6.8m).

It scavenged and also hunted small prey like Dryosaurus. Its main predator and rival was Allosaurus, which eventually drove it to extinction.


Ceratosaurus was a primitive medium-sized theropod that was an ancestor of Carnotaurus and the other abelisaurids. It had short forelimbs with five fingers, signs of it being more primitive than its rival Allosaurus. Its legs were long and muscular, with three toes with sharp claws on the end, designed for fast running. Its skull was double-hinged like a snake, and could open very wide to swallow prey bigger than its head. Ceratosaurus is most distinguishable by the horns above its eyes and the one on its nose. Its tail was somewhat short, but its teeth were thin and blade-like, designed to slice through flesh.
