*"Y. dorngobiensis" Makovicky & Norell, 2006 (type)

"Yamaceratops" is a genus of dinosaur from the Early Cretaceous. It was a primitive ceratopsian which lived in the Gobi Desert of Mongolia.

The type species, "Yamaceratops dorngobiensis", was described by P.J. Makovicky and M.A. Norell in September, 2006. The authors consider the animal to have had an intermediate phylogenetic position between "Liaoceratops" and "Archaeoceratops" within Neoceratopia. Examination of the frill of "Yamaceratops" has convinced the authors that the frill was not used for display, and that the fossils " [hint] at a more complex evolutionary history for ceratopsian frills."cite journal |last=Makovicky |first=Peter J. |coauthors=and Norell, Mark A. |year=2006 |title="Yamaceratops dorngobiensis", a new primitive ceratopsian (Dinosauria: Ornithischia) from the Cretaceous of Mongolia |journal=American Museum Novitates |volume=3530 |pages=1–42 |url=http://digitallibrary.amnh.org/dspace/bitstream/2246/5808/1/N3530.pdf |format=pdf |doi=10.1206/0003-0082(2006)3530 [1:YDANPC] 2.0.CO;2 |doilabel=10.1206/0003-0082(2006)3530[1:YDANPC]2.0.CO;2]

The genus name refers to Yama, a Tibetan Buddhist deity; the species name to the Eastern Gobi. The holotype IGM 100/1315 consists of a partial skull; other material has been found in 2002 and 2003 and has been ascribed to the genus.

A fossilized embryo found within an ornithischian eggshell from sediments where "Yamaceratops" is common may belong to this genus.Balanoff A.M., Norell, M.A., Grellet-Tinner, G., and Lewin, M.R.
