  Genus Ornithomimus
Ornithomimus was an ominovorous dinosaur that lived in the late Cretaceous period, about 76 to 65 million years ago. Fossils have been found in North America and Asia.

It was about 12 feet (3.7 meters) long. It would have held its body parallel to the ground, balanced by its extra long tail.

Ornithomimus was a fast runner, and could probably have reached speeds of about 30 miles per hour (50 kilometers per hour). It probably ate insects, small reptiles, mammals, fruit, and leaves. It may also have raided the nests of other dinosaurs to steal and eat their eggs.

The creature's name means "bird mimic" and was chosen by Othniel C. Marsh in 1890. Marsh chose the name based only on a foot and partial hand of the first species found, Ornithomimus velox. In 1933, a more complete skeleton of a second species, Ornithomimus edmontonicus was found in Canada.
