Cryolophosaurus

Cryolophosaurus (Frozen Crested Lizard)

6m Long

Antarctica

Early Jurassic (170 MYA)

Carnivore

Theropoda

'''This slim and large predator was one of the few dinosaurs to have successfully colonized Antarctica, for Cryolophosaurus it was a paradise during the early Jurassic but the environment did have a lack of the normal amount of species of dinosaurs in Antarctica though this meant more territorial room for Cryolophosaurus to get bigger than most early Jurassic predators. This predator would have ambushed primitive sauropods or any other kind of plant eating dinosaur that were living around in the bottom of the world. The crest on the head is the most special feature of this dinosaur above all for it's crest and maybe even head color for males would have been brightly colored so that way when giving out a mating display to the females the bright colors make them more attractive and possible give out a courtship dance to entice the female into mating even more so.'''

Despite being thought to having a slim body it was actually a bit of a bulky large body which probably meant two things: 1 it needed body fat to survive slightly cold seasons in the south pole or 2 it needed a large body so that it can take on larger prey that either just as big or even bigger than Cryolophosaurus.
