Genus: Rinchenia Osmólska, Currie & Barsbold, 2004
Species: Rinchenia mongoliensis (Barsbold, 1986)
Synonyms Oviraptor mongoliensis Barsbold, 1986
Rinchenia is a genus of Mongolian oviraptorid dinosaur from the late Cretaceous Period. The type (and only known) species, Rinchenia mongoliensis, was originally classified as a species within the genus Oviraptor (named Oviraptor mongoliensis by Rinchen Barsbold in 1986), but a re-examination by Barsbold in 1997 found differences significant enough to warrant a separate genus.
The name Rinchenia was coined for this new genus by Barsbold in 1997, though he did not describe it in detail, and the name remained a nomen nudum until used by Osmólska et al. in 2004.
