Protoceratops is a remarkable dinosaur, mainly because there is so much fossil material left behind. Entire nests have been found, along with many individuals in various stages of development.
Because of this fossil evidence, scientists were able to piece together the growth stages of Protoceratops as it develops from infant towards adulthood.
Protoceratops was about the size of a modern day pig, and spent its life in what is now the Gobi Desert. This animal was one of the first ceratopsia, or horned dinosaurs. It did not have well developed horns, but instead had bumps on its prominent head frill.
Like other horned dinosaurs, Protoceratops also had a sharp parrot-like beak.
