It is a dinosaur resembling a rhinoceros, with a bulky appearance, thick legs, three horns on the head, and a large bone plate extending backwards at the back of the skull to form a neck shield. There is a short horn above the beak and two long horns above the eye sockets. The horns of Triceratops are defensive weapons that can scare off predators. The tail is short and pointed, and the feet are like hooves. Distributed in North America, it lived in the late Cretaceous period, approximately 68 to 65 million years ago. Triceratops often take advantage of their clustered lifestyle to protect their young; When facing enemies, often bow down and use horns to resist predators.
