These herbivorous dinosaurs shared common features including the bony frill at the back of the head, one Or more horns, And a mouth with a beak. All moved on four legs And may have roamed around in herds eating low-growing vegetation. Short think legs supported bulky bodies. It can be compared to the present-day rhinocerous in nature, but would have been twice the size.

The horns must have been used for defence with the dinosaur charging straight towards any potential enemy. Triceraptops, the most famous of the ceratopsians, had two large horns above the eyes And a shorter horn on the nose.
