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

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

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

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

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

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

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