family of dinosaurs (fossil) From Wikipedia, the free encyclopedia
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).
