A raptor (or Velociraptor) is a small, hostile, carnivorous dinosaur. Raptors are rather frail but run extremely fast and hit very hard. They are incorrectly depicted without feathers.
Oviraptor is a genus of small Mongolian theropod dinosaur, first discovered by the paleontologist Roy Chapman Andrews, and first described by Henry Fairfield Osborn, in 1924.
The Oviraptor uses the same model as the Raptor, but is not aggressive. You can put one in an enclosed space with a man and it will not attack, despite being a predator.
