About Atlascopcosaurus
What it was like
Atlascopcosaurus was a small, two-legged plant eater, perhaps about 3 meters (10 feet) long. It is known mainly from jaws and teeth.
Its world
It lived about 113 to 110 million years ago, in the Early Cretaceous, in Australia. The land then lay close to the pole, with long dark winters. Its bones come from the Eumeralla Formation, where it lived alongside the small plant eater Leaellynasaura and the theropod Timimus.
How it was found
Rich and Vickers-Rich named Atlascopcosaurus in 1989. The name honors a company that provided tools for the dig.
