ceratopsian, also called ceratopian, any of a group of plant-eating dinosaurs from the Cretaceous Period (146 million to 66 million years ago) characterized by a bony frill on the back of the skull and a unique upper beak bone, called a rostral.
What is one of the differences between Pachyrhinosaurines and ceratopsians?

What did ceratopsians look like?
Early members of the ceratopsian group, such as Psittacosaurus, were small bipedal animals. Later members, including ceratopsids like Centrosaurus and Triceratops, became very large quadrupeds and developed elaborate facial horns and frills extending over the neck.
Why did ceratopsians have frills?
The ceratopsian frill provided protection for the neck, normally one of the most vulnerable parts of the body to be targeted by predators. Horns on the nose and brow were undoubtedly dangerous weapons when thrust into action by an angry ceratopsian.
Where did ceratopsians originate?
Asia
Ceratopsia appears to have originated in Asia, as all of the earliest members are found there.

Diabloceratops was a medium-sized, moderately built, ground-dwelling, quadrupedal herbivore, that could grow up to an estimated 5.5 m (18.0 ft) long. At the time of its discovery, it was the oldest-known ceratopsid, and first centrosaurine known from latitudes south of the U.S. state of Montana.
What type of animal is a Ceratopsidae?
Ceratopsidae (sometimes spelled Ceratopidae) is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous.
What are the characteristics of ceratopsid teeth?

How did ceratopsids form herds inland?
This hypothesis portrays ceratopsids as living in small groups near the coasts during the rainy season and inland with the onset of the dry season. Support for the idea that ceratopsids formed herds inland comes from the greater abundance of bonebeds in inland deposits than coastal ones.
