Xixiasaurus had 22 teeth in its upper jaw, and they had no serrations, which is unusual for a meat-eating dinosaur.2

Its skull was almost complete when found, but the back part was missing.1

The only known fossil includes part of the right arm and hand, with a complete first finger.2

Scientists think Xixiasaurus was closely related to Byronosaurus, another troodontid from Mongolia.1

The age of the rocks where it was found is debated, with estimates ranging from about 100 to 72 million years old.1

Because its nasal bones were not fused, the only known Xixiasaurus might have been a young animal.1

Las dumondas las pli frequentas davart Xixiasaurus

?How big was Xixiasaurus?

Xixiasaurus was about 1.5 metres (5 ft) long and weighed around 8 kilograms (18 lb). That is about as long as a small bicycle and as heavy as a large cat.1

?What did Xixiasaurus eat?

Scientists think Xixiasaurus may have been herbivorous or omnivorous because its teeth lacked serrations and could not slice meat. It probably ate plants and maybe small animals.1 2

?Did Xixiasaurus have feathers?

Yes, Xixiasaurus probably had feathers. Other troodontid dinosaurs like Jianianhualong had pennaceous feathers, so Xixiasaurus was likely covered in feathers too.1

?When did Xixiasaurus live?

Xixiasaurus lived during the Late Cretaceous Period, about 100 to 72 million years ago. The exact age of the rocks where it was found is still debated.1

Chatschader da mitus

Mitus: Xixiasaurus was a fierce meat-eater like other raptors.

Vardad: Its teeth had no serrations, so scientists think it may have eaten plants or a mix of plants and meat.2
