“[The creature was] hog sized but somewhat resembling an iguana.” — Arthur DenisonProtoceratops (meaning 'First Horned Face', derived from Ancient Greek proto-/πρωτο- 'first', cerat-/κερατ- 'horn' and -ops/-ωψ face) was a sheep-sized (1.5 to 2 metre long) herbivorous ceratopsian dinosaur, from the Upper Cretaceous Period. 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.
The protoceratops on Dinotopia are of a variety known as Protoceratops multilinguos. They are capable of mimicking a stunning array of sounds, and are thus one of the few dinosaur species capable of not only speaking various saurian languages, but human languages as well. As such, proteceratops are often employed as ambassadors and translators.
