Fossils of Cryolophosaurus were found in rocky outcroppings near the Beardmore Glacier in Antarctica, which is 13,000 feet (4,000 meters) above sea-level, and today lies just 400 miles (650 kilometers) from the South pole. At the time it lived, Antarctica was slightly further North, and so its position at the time would perhaps have been around 1000 miles (1,650 kilometers) from the South pole. In any case, this find (along with a number of other fossils found nearby, which include other dinosaurs, a pterosaur, and a Tritylodon mammal-like reptile, as well as fossilized tree trunks), seems to provide support to the theory that the Jurassic period was much warmer than today, and the Antarctic had forests, even at high altitudes.
Cryolophosaurus was about 20 to 26 feet (6 to 8 meters) long, and probably weighed around 1,100 pounds (500 kilograms).
Like its relative, Dilophosaurus, Cryolophosaurus had a crest on its skull. The unusual nature of its crested, caused Cryolophosaurus to gain the nickname "Elvisaurus", based on its supposed resemblance to one of Elvis Presley's hairstyles.
Cryolophosaurus was a carnivore (meat-eater) that lived from 196 to 1960 million years ago
