Oviraptor is the most famous representative of a vast group of brevirostrate dinosaurs that lived at the end of the Cretaceous period about 75 million years ago in the territory of modern Mongolia, in the Gobi Desert, where their remains were first discovered in 1923. Oviraptor was a small agile dinosaur that ran fast on two legs. It had an unusually shaped head, similar to the head of a parrot, and sharp claws on the limbs, a powerful beak without teeth and rather large eyes compared to the size of the skull. There were three fingers on the forelimbs, each ending in a long sharp claw. The thick beak of the oviraptor was perfect for splitting shells of clams and crabs. It also hunted small animals. In the stomach of the only skeleton of oviraptor found, scientists found bones of a small lizard. Some scientists also believe that it could feed on plants. The rock in which the remains of this dinosaur were found was red, so scientists suggested that it lived in a dry and warm climate.
