This carnivorous dinosaur (meat eater) had a strong jaw with teeth like blades. Although it could have fed on large dinosaurs, scientist think it may have fed on fish and crocodiles.

Ceratosaurus timeline - Jurassic period

It lived in the late Jurassic period (about 153-148 million years ago). Around the same time as the Allosaurus and Brachiosaurus dinos.

Its dinosaur classification is Theropoda.

Ceratosaurus skull

It had horns above and forward of its eyes - and a large nose horn.

There are lots of suggestions about what it used its horn for - some scientists think it helped the hatchling dinos to break out of their eggs, others that it was used for non lethal fighting among males. Scientists don't think that it would have been much protection against predators.
