Caenagnathasia

Caenagnathasia ('recent jaw from Asia') is a genus of small caenagnathid oviraptorosaurian theropod from the Late Cretaceous of Uzbekistan.

==Discovery== The type species Caenagnathasia martinsoni was named and described in 1994 by Philip J. Currie, Stephen Godfrey and Lev Nessov. The generic name is a combination of a reference to the species' placement in the Caenagnathidae, with Asia, the continent of its provenance. The specific name honours Gerbert Genrikhovich Martinson. The genus is based on holotype N 401/12457, a pair of fused dentaries of the lower jaws. The specimen was found near Dzharakuduk in layers of the Bissekty Formation, dating to the Turonian-Coniacian, around 90 mya, making it the oldest known caenagnathoid. A second specimen was referred to the species, N 402/12457, a right dentary of a slightly smaller individual. Both individuals were adult. In 2015, new material of Caenagnathasia was described. From the same site as the holotype, the material includes various vertebrae, a dentary, and a femur.
