Oviraptor
In 1976, Barsbold put six more brooding (nest sitting) specimens into the genus Oviraptor, but these were later reclassified in the new genus Conchoraptor. Another specimen, IGN 100/42, is perhaps the most famous, owing to its well-preserved complete skull and large size. This specimen was referred to the genus Oviraptor by Barsbold in 1981, and was presented as Oviraptor in popular magazines and scientific studies. However, this specimen, with its distinctive tall, cassowary-like crest, was re-examined by the scientists who described the nesting oviraptorids, and found to resemble them more closely than the original specimens of Oviraptor. For this reason, they removed IGN 100/42 from the genus Oviraptor, suggesting it was a species of Citipati.
