Triceratops (Greek for "three-horn face") is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago (Mya) in what is now North America. It is one of the last known non-avian dinosaur genera, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago. The term Triceratops, which literally means "three-horned face", is derived from the Greek τρί- (tri-) meaning "three", κέρας (kéras) meaning "horn", and ὤψ (ops) meaning "face". In the Eur'uui Universe, the entire species survived when they were teleported into the world of Zhecronus by the Zhecrons in attempt to save them from extinction, where they now live within dense forests, tropical jungles, and vast plains. They are sometimes territorial creatures that usually charge upon those of predators (including Tyrannosaurus Rex and Spinosaurus), unlucky tourists, and foolish pranksters in the same manner as the rhino.
