Genera and Species
Classification: Theropoda, Tetanura, Coelophysoidea
Species: C. ellioti
It has a deep, narrow skull with a large lacrimal crest with orbital horn fused to the crest on each side. It was found in association with bones from a prosauropod, a pterosaur, synapsids and other unidentified theropods.
LENGTH: 6 m (27 - 36 ft).
It preyed upon the primitive sauropodomorphs. The crests were used for display in territorial or breeding contests.
History of Discovery
Discovered by Hammer and Hickerson, in 1994 it is the first carnivorous dinosaur found in Antarctica and the first dinosaur described from Antarctica.
Cryolophosaurus lived in central Antarctica and the environment has been reconstructed as a wet temperate forest with daylight dominated summers and dark cold winters. Antarctica was probably a collection of islands during the Mesozoic.
