PROTOCERATOPS

Protoceratops was a dinosaur of the Cretaceous period. Remains of Protoceratops were first discovered in Mongolia in 1922 and these remains included complete nests of eggs with skeletons of young and old. The adult Protoceratops was 180 centimetres long, walked on all fours, had a pointed beak and a small neck frill. Unlike later related dinosaurs, Protoceratops was devoid of horns but had thickened bony areas on top of the snout and above the eyes.
