Antarctica

When dinosaurs were alive, Antarctica was a warm, ice-free place, lying farther north than now. Cryolophosaurus, an Early Jurassic carnivorous dinosaur of 195 million years ago, and older Triassic reptiles such as Lystrosaurus were found here in the 1990s, in the vicinity of Mount Kirkpatrick. They had lived beside a river on a low-lying woodland plain. Long after they ceased to exist, the Earth's temperature cooled, glaciers spread, and the land was pushed up to form today's ice-capped mountains of Antarctica.

CRYOLOPHOSAURUS SKELETON

An almost complete Cryolophosaurus skull, together with other parts of its skeleton, was found high up near the summit of Mount Kirkpatrick. The skull, which is similar to that of Allosaurus, measures 25 in (65 cm) long, and its jaws hold many backward-pointing teeth with serrated edges—the teeth of a predatory meat-eater.
