Triceratops, the "Three Horned Face," is a dinosaur of particular interest, being widely represented in both entertainment and in the fossil record. Its stout, powerful body reached lengths of nine meters and heights of three meters. Triceratops was a force of nature few reckoned with, emblazoned with its mighty frill and horns. These iconic ornaments grew as it reached maturity. Triceratops are commonly depicted using their headgear as weapons, but recent theories that note the presence of blood vessels in the skulls suggest that the frill was most likely used for courtship. Triceratops shared the warm North American climates of the Maastrichtian age of the Cretaceous with fearsome foes like the Tyrannosaurus. In the event of a confrontation, its horns could be used to ward off or gore oppontents into submission. It lived in relative harmony with other herbivores during its reign before he mass extinction at the end of the Cretaceous. It browsed low-hanging vegetation with its beak lined with rows of teeth, which sheared leaves off fibrous plants like palms, ferns, and cycads. Due to the large amount of Triceratops fossils that have been found, it is safe to say that Triceratops was one of, if not the, most common herbivores of the Period.
