Rinchenia is a genus of oviraptorid dinosaur from the Late Cretaceous Period. It is only known by one species, R. mongoliensis. This specimen was originally named as an Oviraptor in 1986 by Rinchen Barsbold, but after further studies in 1997 by Barsbold, and in 2004 by OsmÃ³lska, the name was finally changed to Rinchenia.
Rinchenia is known only from a single specimen consisting of a complete skull and lower jaw, partial vertebrae, partial forelimbs, partial hind limbs, pelvis, and wishbone. It was a 5 foot long dinosaur. Although it was similar to an Oviraptor, many of its bones show some variation and uniqueness. Rinchenia also had a well-preserved crest.
