Today I'm going to tell you about Cryolophosaurus.
This dinosaur has a crest on its head. It lived in Antarctica during the Jurassic time period. It is special because not many dinosaurs have been in Antarctica. But during the Jurassic Antarctica was hot, not cold.
Crylophosaurus is smaller than an Allosaurus. Allosaurus doesn't have a crest, but Ceratosaurus had three horns on his head.
Crylophosaurus would eat meat and kill other creatures that lived in the Jurassic. In the Jurassic it was very hot. And that's it.
