Ceratopsidae (sometimes spelled Ceratopidae) is a family of dinosaurs including Triceratops, Torosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous, mainly of Western North America (though Sinoceratops is known from Asia^[1] as well as possible fossils in Japan, and Kazakhstan)^[source?] and are characterized by beaks and elaborate horns and frills. The group is divided into two subfamilies (see Taxobox).
