What is a Ceratopsian?

Ceratopsians were a group of herbivorous dinosaurs that thrived during the late Cretaceous period. They are known for their distinctive headgear, which includes frills and horns. Ceratopsians started as small, bipedal creatures but evolved into large, quadrupedal dinosaurs. They were unique for their beaked mouths, which were excellent for cropping vegetation.

Examples of Ceratopsians: Ceratopsia

Ceratopsia, a major group within Ceratopsians, includes well-known dinosaurs like Triceratops and Pachycephalosaurus. These dinosaurs are characterized by their large bony frills, which likely served both defensive and social purposes. Triceratops, with its three facial horns, is one of the most recognizable dinosaurs and was a significant herbivore of its time, using its strong beak to munch on tough plants. Another member, Pachycephalosaurus, is famous for its thick, domed skull, believed to be used in head-butting behavior, although it's more closely related to ceratopsians through evolutionary links than to traditional horned patterns.
