|Species||T. horridus; T. prorsus|
Triceratops ("three-horned face") was a large North American ceratopsian (horned) dinosaur. It had a large bony frill protecting its neck and three horns - one over each eye and a smaller one on its beaked snout.
Triceratops was herbivorous, up to 26 feet long, and could weigh up to 6 tons. The skull of Triceratops, which is approximately a third of the entire animal's length, is among the largest known for all land animals.
Paleontologists once believed there were several species of Triceratops, judging from the large number of fossil remains, but it is now thought that there were just two, T. horridus and the larger T. prorsus. In the evolutionary paradigm, they would have been among the last of the dinosaurs, living in the late Cretaceous period. Fossils of Triceratops have so far been found only in North America.
