趣味知識

Atrociraptor was named in 2004, nine years after its fossil was found by a fossil hunter named Wayne Marshall.1

Only the front parts of its jaws and some teeth have ever been found, so scientists guess what the rest looked like from its relatives.1

Atrociraptor lived during the Late Cretaceous period, about 69 million years ago, in what is now Canada.1

It belonged to the dromaeosaur group, which includes fast, feathered hunters like Velociraptor.1

Scientists have debated whether Atrociraptor was more closely related to Velociraptor or to other dromaeosaurs like Saurornitholestes.2

?How big was Atrociraptor?

Atrociraptor was about 2 metres long and weighed about 15 kilograms, similar in size to Velociraptor.3 1

Atrociraptor lived during the Late Cretaceous period, about 72 to 69 million years ago, in what is now Alberta, Canada.3 1

?Where was Atrociraptor found?

Its fossils were found in the Horseshoe Canyon Formation in Alberta, Canada, about 5 kilometres from the Royal Tyrrell Museum.3 1

?Is Atrociraptor related to Velociraptor?

Yes, Atrociraptor is a relative of Velociraptor, but scientists are not sure how closely. It may be more closely related to Saurornitholestes.3 1

?Why is it called Atrociraptor?

The name means 'savage robber' in Latin, and the species name marshalli honors Wayne Marshall, who found the fossil.3 1

Yes, Atrociraptor appeared in the 2022 film Jurassic World Dominion, where it was shown as more 'brutish' than Velociraptor.3
