Datos curiosos

1

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

2

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

3

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

4

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

5

Some scientists once thought Ornitholestes was the same dinosaur as Coelurus, but most now agree they are different genera.12

6

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