Cryolophosaurus had a forward-facing crest on its head. It is also known (informally) as Elvisaurus, due to the crest's likeness to Elvis Presley's hairdo. The Antarctic, where Cryolophosaurus was found, was warmer when Cryolophosaurus lived than it is now - during the Jurassic period, the Antarctic was closer to the equator and part of a larger continent - plus, the climate in general was warmer.
now he will be run in zoo tycoon 2.
thank to ~hellraptor for the awesome design
