While the original specimen of Oviraptor was poorly preserved, especially the crushed and deformed skull, new and more complete oviraptorid specimens were assigned to the genus in the 1970s and 1980s.
Dok je originalni primjerak Oviraptora bio u lošem stanju, a posebno slomljena i deformirana lubanja, noviji i potpuniji primjerci oviraptorida su pridodati ovom rodu u 1970-im i 1980-im.
