Introduction

Ceratopsians were a group of herbivorous dinosaurs characterized by their horns, frills, and beaked mouths. They were common during the Late Cretaceous period, particularly in North America.

Anatomy and Features

Ceratopsians possessed a variety of horns and frills, which may have been used for display, defense, or species recognition.

Social Behavior

Fossil evidence suggests that some ceratopsians, such as Triceratops, lived in herds.

Evolution

The ceratopsians evolved from smaller, bipedal ancestors in Asia.
