Datu dibertigarriak

Cryolophosaurus was one of the earliest large meat-eating dinosaurs, living about 170 million years ago in the Early Jurassic.1

Its curved head crest is unique among early theropods and may have been used to attract mates or recognize other members of its species.1

Fossils of Cryolophosaurus were found alongside bones of a prosauropod, teeth from scavenging theropods, a pterosaur humerus, and a tritylodont molar.2

The discovery of Cryolophosaurus in Antarctica suggests that a mild climate existed there during the Early Jurassic.2

Cryolophosaurus walked on two legs and was a ground-dwelling carnivore.5 1

Cryolophosaurus: gehien egindako galderak

?How big was Cryolophosaurus?

About 6 to 7 metres (20 to 23 ft) long and weighed 350 to 465 kilograms (772 to 1,025 lb). Some adults may have reached 8 metres (26 ft).4 1

?What did Cryolophosaurus eat?

It was a carnivore, meaning it ate other animals. It had many sharp, pointed teeth for eating meat.1

?Why did Cryolophosaurus have a crest?

Scientists think the crest was used for display, like to recognize other members of its species or attract mates. It was not used as a weapon.4

?Where was Cryolophosaurus found?

Its fossils were discovered in Antarctica, on Mount Kirkpatrick near the Beardmore Glacier. It lived there about 170 million years ago.4 1

?When did Cryolophosaurus live?

It lived during the Early Jurassic Period, about 196 to 188 million years ago.4 1

?Is Cryolophosaurus a dinosaur?

Yes, it is a dinosaur. It is a large theropod dinosaur, which is a group of meat-eating dinosaurs that walked on two legs.1 4

?How fast could Cryolophosaurus run?

Nobody knows for sure. Since it was a large theropod that walked on two legs, it was probably a fast runner, but no exact speed has been estimated.1

?Was Cryolophosaurus bigger than T. rex?

No, it was much smaller. T. rex was over 12 metres long, while Cryolophosaurus was only about 6 to 8 metres long.4
