Cryolophosaurus was a carnivore (meat-eater) that lived in the Antarctic
during the early
Jurassic period,
between about 196 and 190 million years ago.
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 Tritylodonmammal-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 member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Cryolophosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
Cryolophosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Cryolophosaurus was not itself an ancestor of birds).
Cryolophosaurus lived between about 196 million years ago and 1960 million years ago.
Cryolophosaurus lived in Antarctica.
