Rinchenia mongoliensis (Barsbold, 1986)

Name Means: Rinchens Length: 8 feet (2.5 m)
Pronounced: rin-Chen-ee-uh Weight: 300 pounds (136 kilos)
When it lived: Late Cretaceous - 70 MYA    
Where found: Mongolia, China    
   A complete fossil of this little dinosaur was found at Altan Ula in the Nemegt Formation in Mongolia.  It looked exactly like an Oviraptor and was originally named Oviraptor mongoliensis by Barsbold in 1986.  Subsequent and more detailed study revealed important differences.  The main one seems to be the shape of the crest on the top of its head, and how some of the bones that attached to this crest were formed.  The new species had  the tallest head crest of any oviraptorid. The dome-like crest that incorporates the parientals in addition to the premaxillae, nasals and frontals. The postcranium is more lightly built and the cervical vertebrae are rather low in comparison with those of Oviraptor.  These differences led to it being renamed Rinchenia mongoliensis by Barsbold in 1997.
   In recent studies of Oviraptors, it appears that each individual would have had a different crest shape and size. North American members of this family discovered to date are considerably larger than their Asian cousins. It is possible that Rinchenia merely exhibits individual traits and is in fact an Oviraptor. As of this writing, it has not been formally described.
