Sterrholophus

Triceratops is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago on the island continent of Laramidia, now forming western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, which means 'three-horned face', is derived from the Ancient Greek words τρί- (trí-), meaning "three", κέρας (kéras), meaning "horn", and ὤψ (ṓps), meaning "face". Bearing a large bony frill, three horns on the skull, and a large, four-legged body, exhibiting convergent evolution with rhinoceroses, Triceratops is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around 8–9 m (26–30 ft) long and weighing up to 6–10 t (5.9–9.8 long tons; 6.6–11.0 short tons)
