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.[1] 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.[2]
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).[3] 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.[4]
