名字的意思： “evil lizard”1

吃：肉迅猛龍類白堊紀晚期

Adasaurus was a feathered raptor that lived in what is now Mongolia. It had a small, blunt sickle claw on its foot, unlike most other raptors. Scientists think it may have used this claw less often for hunting.1

趣味知識

Adasaurus had a small, blunt sickle claw on its second toe, unlike the big, sharp claw of most raptors.1

It lived about 70 to 68 million years ago, during the Late Cretaceous period.1

Adasaurus is a dromaeosaurid, a group of dinosaurs closely related to birds.1

The first fossils of Adasaurus were found in the 1970s and named by Mongolian paleontologist Rinchen Barsbold in 1983.1

Some scientists once thought the small sickle claw did not belong to Adasaurus, but later studies confirmed it was real.1

Adasaurus shared its home with giant dinosaurs like Tarbosaurus and Deinocheirus.1
