context_page_description: Vagaceratops is a genus of herbivorous ceratopsian dinosaur. It is a chasmosaurine ceratopsian which lived during the Late Cretaceous period in what is now Alberta. Its fossils have been recovered from the Upper Dinosaur Park Formation.
context_section_description: Vagaceratops was named by Scott D. Sampson, Mark A. Loewen, Andrew A. Farke, Eric M. Roberts, Catherine A. Forster, Joshua A. Smith, and Alan L. Titus in 2010, and the type species is Vagaceratops irvinensis.  This species was originally described as a species of Chasmosaurus (C. irvinensis) in 2001. Its relationships remain debated. Vagaceratops has variously been allied with Kosmoceratops or with Chasmosaurus.
