Yamaceratops is an early ceratopsian genus that inhabited Asia during the Late Cretaceous period in what is currently recognized as the Javkhlant Formation. It was first discovered in the Javkhlant formation of the Gobi Desert in Mongolia. The dinosaur's name, "Yamaceratops," is derived from "Yama," the name of a local deity in Mongolian folklore, and "ceratops," which refers to the distinctive horned face shared by ceratopsians.

The dinosaur was classified and described by renowned paleontologist Makovicky and his team in 2006. It belongs to the family Protoceratopsidae, a group of small to medium-sized ceratopsians known for their beaked faces and unique frills.

Yamaceratops was a relatively small dinosaur, measuring around 0.5 metres (1.6 feet) in length. As a protoceratopsid, it had a compact body with sturdy limbs, suitable for supporting its weight and navigating its environment.

One of the most distinguishing features of Yamaceratops is its unique frill, which featured long, forward-curving extensions. This distinctive frill set it apart from other ceratopsians, making it easily recognizable in the fossil record. Additionally, like other members of the Protoceratopsidae family, Yamaceratops lacked the large nasal horn typically seen in some of its larger ceratopsian relatives.
