Ornitholestes 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.
An oftenly-portrayed inaccuracy in media is that it has a horn on the tip of its snout, which has been disproven.
Jurassic Park franchise
Ornitholestes appeared in the website Jurassic Park: Institute on Dinopedia and it is shown to be inaccurate haveing a nasal crest similar to the portrayal of Walking with Dinosaurs.
Campers find the corpse of a large reptile on the beach of Rojas. Martin "Marty" Guitierrez invites Richard Levine to identify the creature. The corpse is destroyed by soldiers shortly after the scientists arrive. Levine identifies the creature as an Ornitholestes.
Levine manages to save a skin sample from the creature. The sample is sent to Ian Malcolm. Elizabeth Gelman analyzes the sample and shows the results to Malcolm. The skin has a structure comparable with pelicans; although it doesn't have feathers. It also has a 2 cm square green plastic radio tag.Elizabeth Gelman also notes that the skin contains a density of chromatophores, or pigment-bearing cells. The chromatophores could open and close, meaning that this animal could change color like a chameleon. Although there is no factual evidence that the dinosaur can.
Ornitholestes is no. 024 of the Carnivore Ones that can be created in Jurassic Park III: Park Builder. It is portrayed with a horn on its head, which has since been disproven.
Ornitholestes is set to be part of the "Attack Packs" assortment for the upcoming Primal Attack line in 2020. This will be the first time it has ever appeared in any Jurassic Park toy set. The coloration is brown with yellow face markings, white stripes on its back, and a white underbelly.
