Xenoceratops (meaning “Alien Horned-Face”*) is a genus of centrosaurine ceratopsian of the tribe pachyrhinosaurini from the Late Cretaceous of Canada. Michael J. Ryan, David C. Evans, and Kieran M. Shepherd described the type species X. foremostensis in 2012. The species name, foremostensis means “from Foremost Formation”, the formation in Alberta, Canada where Xenoceratops was discovered. Although it was described in 2012, the fossils were collected in 1958 by Wann Langston, jr. He stored them at the Canadian Museum of Nature in the capital of Canada, Ottawa. Ryan and Evans first became interested in the specimen in 2003. By 2009, it was found go be a new genus. Shepherd helped them describe it and their description was published in 2012. It is the oldest genus of ceratopsian discovered from Canada and the first discovered from the Foremost Formation in Alberta. It is closely related to Sinoceratops.
*Some people translate Xenoceratops as “foreign horned-face”. I included the most popular translation. Another possible translation is “strange horned-face”.
