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.
Platyceratops belonged to the Ceratopsia (the name is Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period, which ended roughly 66 million years ago. The validity of Platyceratops remains in doubt. Both Platyceratops and Bagaceratops were found at the same locality, the Red Beds at Khermeen Tsav, which raises the possibility that they are in fact the same species.
Platyceratops, like all ceratopsians, was a herbivore.
