The Protoceratops is a herbivorous ceratopsian dinosaur that lived in the Upper Cretaceous Period in what is now Mongolia. It was a member of the Protoceratopsidae, a group of early horned dinosaurs. It was a quadrupedal dinosaur that was characterized by its distinctive neck frill at the back of its skull; the frill had two large parietal fenestrae (holes in the frill), and the cheeks had large jugal bones. Comparisons between the scleral rings of the Protoceratops and modern birds and reptiles indicate that the dinosaur had a cathemeral lifestyle- active throughout the day during short intervals.
The Protoceratops had an overall length between 4.9’-5.9’ (1.5-1.8 m), standing height of 19.7”-23.6” (50-60 cm), and body width of 13.8”-19.7” (35-50 cm). The weight of the Protoceratops was between 350-400 lb (159-181 kg).
