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".
