Triceratops was a herbivorous, ornithischian dinosaur, or of the order of bird hipped. Its beak had rows of grinding teeth suggesting they dined on tough vegetation. The discoveries of bone beds, which are large deposits of bones in the same area of the same species, suggests that Triceratops traveled in herds. (Many of the Triceratops fossils have been found in western Canada and western United States.) Fossils of young and adult Triceratops found in the same area, hint that they cared for their young. .

The Triceratops had a mysterious feature located on its head. It was called a frill. It was probably not used to attract mates. Many people originally thought that the frill was used for protection. This was probably not the case because the frill was very porous. The frill was probably used to make the animal bigger, serving as a form of intimidation. The holes in the frill were used to make the frill lighter, taking stress of the animals neck. As it turns out the frill was probably used as a heat radiator. Reese Barrick, who measured oxygen isotope levels in different parts of the Triceratops body, including the frill, found evidence to support this. Oxygen comes in two forms, oxygen 18, which tends to be attracted to cold, and oxygen 16, which tends to be attracted to heat. The horns were rich in oxygen 18 as well as were the feet. The sample taken from the body was rich in oxygen 16. This made sense because the body was very hot while the animal was alive. The frill had oxygen 16 in the middle, but had oxygen 18 on the outside. This suggests that the heat rose up into the frill, and then was released through the holes at the end.
