Ornitholestes (ORN - ith - oh - LESS - tees) was a small theropod dinosaur that lived in the Late Jurassic Period in North America. The single existing specimen of Ornitholestes was found in Bone Cabin Quarry in Wyoming in 1900 and described by Henry Fairfield Osborn in 1903. It consists of an almost complete skeleton and a complete, but compressed skull. It is on display in New York at the American Museum of Natural History.
