Protoceratops (meaning 'First Horned Face') is a genus of sheep-sized (1.5 to 2 m long) herbivorous ceratopsian dinosaur, from the Upper Cretaceous Period (Campanian stage) of what is now Mongolia. It was a member of the Protoceratopsidae, a group of early horned dinosaurs. Unlike later ceratopsians, however, it lacked well-developed horns and retained some primitive traits not seen in later genera. Protoceratops had a large neck frill, which may have served to protect the neck, to anchor jaw muscles, to impress other members of the species, or combinations of these functions. Protoceratops was a relatively small dinosaur with a proportionately large skull. Although an herbivore, Protoceratops appears to have had muscular jaws capable of a powerful bite. These jaws were packed with dozens of teeth well suited for chewing tough vegetation.
