| Elmisaurus rarus Osmólska, 1981 |
Elmisaurus is an extinct genus of dinosaur from the Late Cretaceous. It was a theropod belonging to the Oviraptorosauria. Its fossils have been found in Asia and North America. It's known from only its feet and hands.
The type species, E. rarus, was described by Halszka Osmólska in 1981.[1] A second species, E. elegans (a North American form originally described as a species of Ornithomimus by William Parks in 1933), was referred in 1989 to Elmisaurus.[2][3] The frequent mis-assignment of this species is probably due to poor preservation and its geographical distance from the type species. More recently, Hans-Dieter Sues demonstrated that this supposed second species of Elmisaurus is actually a junior synonym of Chirostenotes pergracilis.[4]
