Protoceratops, a ceratopsian dinosaur, lived in the late Cretaceous period (approximately 100-65 million years ago). It is a short legged quadruped animal with a body length of 2 meters and a weight of nearly 400 kilograms. The teeth are long and sharp. There are bony folds in the neck and large jaw muscles. May rely on palm leaves as a staple food. A quadrupedal dinosaur with a large head shield behind its head and no horns. Living in groups. They gave birth to small dinosaurs in their own nests. The heads of Protoceratops are of medium size, so they are relatively intelligent. It has a very similar appearance to the famous Triceratops, but is smaller in size and does not have long horns on its head.
