Utuntu dushimishije

1

Huallasaurus was first thought to be a species of Kritosaurus, but scientists later gave it its own name in 2022.1

2

Its name comes from the Mapudungun word 'hualla' meaning duck, because of its duck-like beak.1

3

Huallasaurus lived about 72 to 66 million years ago, near the end of the Age of Dinosaurs.6

4

This dinosaur is known from both adult and subadult fossils, including skull and body bones.2

5

Huallasaurus belonged to a group of South American duck-billed dinosaurs called Austrokritosauria.1

6

It shared its home with the long-necked sauropod Aeolosaurus rionegrinus.1

Scientists are still debating exactly how Huallasaurus is related to other South American hadrosaurs and whether it belongs in the group Kritosaurini or Austrokritosauria.21
