According to LiveScience, Triceratops was a quadrupedal animal with a powerful build, famously characterized by the large, bony frill surrounding its skull and the two pointed horns above its eyes. A smaller horn rested above the snout. Triceratops could grow up to 30 feet long, weighing up to 26,000 pounds.
Triceratops lived in North America near the end of the Cretaceous Period, around 68 to 65 million years ago. Its huge horns were unlikely to be used for aggressive acts and were reserved for defending itself or its young from predators. The impressive frill of the Triceratops is believed to have functioned for defensive purposes and possibly as a radiator.
