Bagaceratopidae is a family of neoceratopsian dinosaurs. It was named by Alifanov in 2003 but no definition has been proposed.[1] Because of lacking of the definition, Bagaceratopidae was considered inactive by Paul Sereno in 2005.[2] Alifanov in 2003 classified to this family four genera: Bagaceratops, Breviceratops, Lamaceratops and Platyceratops[1] and in a publication from 2008 he included in Bagaceratopidae also Magnirostris and newly described genus Gobiceratops. Alifanov suggested also that Bagaceratopidae, unlike other neoceratopsian families, is of Paleoasiatic origin.[3]
Bagaceratopids existed during the late Cretaceous period, between about 85.8 and 70.6 million years ago.[4]
