Nomingia
Template:Short description Template:Automatic taxobox
Nomingia is a genus of oviraptorosaur theropod dinosaur hailing from the Late Cretaceous Bugin Tsav Beds of Mongolia.
Discovery and naming
The remains, consisting of most of the vertebral column, pelvic girdle and left tibio-tarsus, holotype GIN 100/119, were found in 1994 in layers of the Nemegt Svita, dating to the Maastrichtian. They were named and described as the type species Nomingia gobiensis by Barsbold, Halszka Osmólska, Mahito Watabe, Philip Currie and Khishigjaw Tsogtbaatar in 2000. The etymology of the binomial refers to the location where the fossils were found, with the generic name mentioning the Nomingiin Gobi (Template:Langx), one of the "Thirty-Three Gobis" which compose the Gobi Desert, which is itself mentioned in the specific descriptor.[1]
A 2021 article by Funston and colleagues suggested Nomingia is a synonym of Elmisaurus.[2]
Description
Nomingia is a medium-sized oviraptorosaur, estimated by Gregory S. Paul to have been Script error: No such module "convert". long and Script error: No such module "convert". in weight.[3] It is characterized by a pygostyle-like mass of five fused vertebrae at the tail end, which Barsbold et al. inferred probably supported a feather fan as in Caudipteryx.[1] A similar bone structure had only been found in birds before this fossil was discovered.
As other oviraptorids such as Chirostenotes, N. gobiensis would have been a medium-sized theropod sporting beaked jaws and, probably, a crest used for display.
Phylogeny
Barsbold et al. only formally assigned Nomingia to a more general Oviraptorosauria, though they considered that it was likely a member of the Caenagnathidae (=Elmisaurinae).[1] Subsequent cladistic analyses have been contradictory regarding to which precise subgroup it belonged.
