Protoceratops



Protoceratops was a quadrupedal dinosaur that was partially characterized by its distinctive neck frill at the back of its skull. The frill itself contained two large parietal fenestra (holes in the frill), while its cheeks had large jugal bones. undefined The exact size and shape of the neck frill varied by individual; some specimens had short, compact frills, while others had frills nearly half the length of the skull.

Protoceratops was approximately 6 ft in length and 2 ft high at the shoulder. A fully grown adult would have weighed less than 400 pounds. The large numbers of specimens found in high concentration suggest that Protoceratops lived in herds
