Sinoceratops (meaning “Chinese Horned-Face”) is a genus of ceratopsian to the tribe of pachyrhinosaurini from the Late Cretaceous of China. It was described by Xu Xing, et al in 2010. It is the only chasmosaurine not from North America. It is also one of the largest, at 23 feet (7 metres) long. The city of it’s discovery, Zhucheng, has also boasted other very large representations of families, such as the tyrannosaur Zhuchengtyrannus, the crestless hadrosaur Zhuchengosaurus ( now synonymous with Shantungosaurus), and not-so-large ones, such as the small ceratopsian Zhuchengceratops. They all co-existed. It’s closet relative is Xenoceratops foremostensis.
The type species described by Xu Xing, et al is Sinoceratops zhuchengensis. Although it is part of the tribe pachyrhinosaurini, it is not part of the clade pachyrostra. Members of this group include Achelousaurus and the three species of Pachyrhinosaurus: canadensis, lakustai, and perotorum. The main characteristic that sets Sinoceratops apart from the other pachyrhinosaurinis is the presence of 10 (or more) robust strongly curved horn-like structures on it’s frill.
