Oviraptor was a small, feathered, theropod which lived during the Cretaceous. it was once thought to be an egg-eater, since its remains have been excavated near dinosaur nests. these were later found to be the nest of Oviraptor itself, one specimen even showed a mother which had perished while guarding its nest, probably due to a sandstorm or other natural disaster. Oviraptor had a large beak, once thought to be an egg-cracker, it was most likley used to catch lizards and other small creatures. male Oviraptors had flamboyant crests on their heads, most likley used in mating rituals.
