Fatgs divertents

Ornitholestes had big eyes, which were more than one quarter of the length of its skull. This might have helped it see at night.1

Its tail was very long and whiplike, making up more than half of its body length. The tail helped it balance while running.1

The front teeth of Ornitholestes were cone-shaped and not very serrated, but the back teeth were curved and had sharp serrations like steak knives.1

Only one nearly complete skeleton of Ornitholestes has been found. It was discovered in Wyoming in 1900 by a team from the American Museum of Natural History.1

Some scientists once thought Ornitholestes was the same dinosaur as Coelurus, but most now agree they are different genera.1 2

An early drawing by Charles R. Knight showed Ornitholestes chasing the bird Archaeopteryx, but scientists today think it mostly ate ground animals.1
