Chakisaurus was a fast-running, plant-eating dinosaur that lived in what is now Argentina about 90 million years ago. It had a strange tail that curved downward, unlike most other dinosaurs. It could run very quickly to escape predators.1

1

Chakisaurus had a tail that curved downward, which is very unusual for a dinosaur. Most dinosaurs held their tails straight out.1

2

It was a fast runner, and scientists think its curved tail helped it balance while running.1

3

Chakisaurus was about the size of a large dog, reaching 2.5 to 3 meters (8 to 10 feet) long.1

4

It lived during the Late Cretaceous period, about 90 million years ago.1

5

Chakisaurus is the first named ornithischian dinosaur from the Huincul Formation in Argentina.2

6

Its name comes from the Tehuelche word 'chaki' meaning guanaco, a fast South American animal, and 'saurus' meaning lizard.1

Scientists are still debating exactly how Chakisaurus used its downward-curved tail, and whether it helped with running or something else.1
