Nemegtomaia

''Nemegtomaia'' ("Nemegt mother") is a genus of oviraptorid dinosaur from the late Cretaceous Period of what is now Mongolia. The type species, ''Nemegtomaia barsboldi'', was described by Lü, Tomida, Azuma, Dong, and Lee in 2004.〔Lü, J., Tomida, Y., Azuma, Y., Dong, Z. & Lee, Y.-N. (2004). "New oviraptorid dinosaur (Dinosauria: Oviraptorosauria) from the Nemegt Formation of southwestern Mongolia." ''Bulletin of the National Science Museum, Tokyo, Series C'' 30: 95-130.〕 Lü ''et al.'' originally called the dinosaur ''Nemegtia'', a name which was found to have already been used for an ostracod from the same formation (in the Nemegt Basin). The dinosaur was therefore renamed ''Nemegtomaia'' in 2005.〔Lü, J., Tomida, Y., Azuma, Y., Dong, Z. & Lee, Y.-N. (2005). "''Nemegtomaia'' gen. nov., a replacement name for the oviraptorosaurian dinosaur Nemegtia Lü et al., 2004, a preoccupied name." ''Bulletin of the National Science Museum, Tokyo, Series C'' 31: 51.〕


''Nemegtomaia'' is known from relatively good remains and a notably well-preserved skull. The same authors had identified this skull in 2002, as a species of "Ingenia" (now ''Ajancingenia'').〔Lü, J., Dong, Z., Azuma, Y., Barsbold, R. & Tomida, Y. (2002). "Oviraptorosaurs compared to birds." In Zhou, Z. & Zhang, F. (eds). ''Proceedings of the 5th Symposium of the Society of Avian Paleontology and Evolution.'' Science Press (Beijing), pp. 175-189.〕 Despite this early misidentification, ''Nemegtomaia'' belongs to the subfamily Oviraptorinae, not Ingeniinae and may be a close relative of ''Citipati''. Two further specimens were described in 2012. One of these was found associated with a nest with eggs, and this specimen also showed evidence of having been scavenged upon by Skin beetles.〔Fanti F, Currie PJ, Badamgarav D (2012). "(New Specimens of ''Nemegtomaia'' from the Baruungoyot and Nemegt Formations (Late Cretaceous) of Mongolia )." ''PLoS ONE'', 7(2): e31330. doi:10.1371/journal.pone.0031330〕
