Archaeoceratops oshimai

In a rather contradictory manner (arkhaios means "ancient" but neo means "new"), Archaeoceratops is one of the oldest neoceratopsians. It's also one of the smallest ceratopsians (ceratops means "horn face") with many features found in its later-living, giant horn-faced relatives. But funnily enough, a horned-face isn't one of them.
Etymology
Archaeoceratops is derived from the Greek "arkhaios" (ancient), "ceras" (horn) and "ops" (face). The species epithet, oshimai, honors Mr. Oshima, the director of Chunichi-Shinbuan; the Japanese newspaper publisher who supported the expedition that found its remains.
Discovery
The first fossils of Archaeoceratops were discovered in the Xinminbao Group, Gongpoquan Basin, Mazongshan Area, Gansu Province, China, during the Sino-Japanese Silk Road dinosaur expedition in 1992.
The Holotype (IVPP V 11114) includes a well preserved, nearly complete skull, partial vertebral column, and partial pelvis. The paratype (IVPP V 11115) is a partial vertebral column, a nearly complete tail, a partial pelvis, fragmentary hind limb bones, and a complete foot, from a much smaller specimen.

Second Species
Archaeoceratops yujingziensis ("from Yujingzi") is based on CAGS-IG-VD-003, a partial skeleton that wasn't found in the field but amongst the remains of an iguanodont that was being prep'd by Zhang Yu-Qing in 2002. It was named by You et al. in 2010 and is even smaller than the paratype of A.oshimai, being around 55cm in length and 23 high at the hip.
