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 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).
