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.
Several Paleontologists once believed there were several species of Triceratops are known, judging from a 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 were among the last of the dinosaurs, living in the late [[Cretaceous]] period. Fossils of Triceratops have been found only in North America.<ref>''The Complete Book of Dinosaurs'', by Dougal Dixon, Anness Publishing, 2006</ref>
