Cryolophosaurus was a theropod, meat-eating dinosaur that lived in the Rainy Basin.
Cryolophosaurus had a long, narrow skull and walked on two legs like all other theropods. They show a mixture of both primitive and advanced theropod characteristics.
Their most recognizable feature is a crest that runs across the skull instead of along it like most theropods. It is an extension of the skull bones near the tear ducts fused to horns that are above the eyes.
