"Ingenia", the "one from Ingen Khoboor,"[1] comes from several formations in the Upper Cretaceous of the Mesozoic, approximately 70 million years ago, and derives most prominently from the Bugin Tsav beds of the Nemegt Formation, which has also yielded the holotype of Mononykus olecranus. It is known from only a few specimens, which includes only the arms, legs, pelvis, shoulder girdle, and partial skull, and a few vertebrae. Material referred to "Ingenia" comes from older formations, but these are not well described.

[edit] Etymology
"Ingenia yanshini" derives from the Mongolian Ingen Khoboor Depression of Bayanhongor Aimak Mongolia, from whence it was collected. yanshini derives from Prof. Aleksandr Leonidovich Yanshin (1911-1999), who was advisor and mentor to the describer Barbsold Rinchen during his time at the Paleontological Institute in St. Petersburg, Russia.
[edit] Taxonomy and Phylogeny
The name "Ingenia" is currently occupied by that of a nematode, Ingenia mirabilis Gerlach, 1957, neccesitating a replacement name, as mandated by the International Commision on Zoological Nomenclature.
Ingenia is a member of the Oviraptoridae, as distinguished by a pubis with a forward-curving shaft (among other features), and by the unique shape of the lower jaw with a strongly S-curved jaw margin, short snout, and rounded, fused cranial bones. Some material includes paired sternal plates fused along the midline and bearing a short keel (=carina).
