Platyceratops is a dinosaur from the Late Cretaceous, during the Campanian Age, about 75-72 million years ago. Its fossils have been found in Mongolia. Its skull is larger than Bagaceratops; it has been referred to Bagaceratopidae or the Neoceratopsia. The name platyceratops is derived from Greek, and means "flat horned face". The type specimen is Platyceratops tatarinovi, described by Aliafanov in 2003. It is considered to potentially represent the same species as Bagaceratops.
