Atlascopcosaurus was a small, primitive-looking plant-eater from Australia known only from a jaw fragment and a few teeth.

It is a good example of how scientists can learn a great deal about a dinosaur from a very small amount of fossil material. Atlascopcosaurus's teeth are similar enough to other members of the Hypsilophodon  family to place it in that group, but different enough to establish a new genus.

The distinction that leads scientists to believe that it was a separate genus is the number of ridges on the teeth and their placement in the jaw.

Atlascopcosaurus was named for a sponsor of the expedition that discovered the dinosaur - the Atlas Copco Corporation.
