ceratopsia การใช้

• Brown in 1914 assigned " Anchiceratops " to the Ceratopsia.
• In 1890 Marsh classified them together in the family Ceratopsidae and the order Ceratopsia.
• "' Protoceratopsidae "'is a family within the group Ceratopsia.
• Their bony frill and horns were much smaller than more derived members of Ceratopsia.
• The new arrivals are somewhat taken back by the ceratopsia used as a shuttle bus.
• The evolution of a quadrupedal posture occurred four times, among the ancestors of Euornithopoda, Thyreophora, Ceratopsia and Sauropodomorpha.
• There was a trend towards increasing body size within many dinosaur clades, including the Thyreophora, Ornithopoda, Pachycephalosauria, Ceratopsia, Sauropomorpha, and basal Theropoda.
• The matter bounced back and forth, over the next few years, until R . S . Lull published his " Revision of the Ceratopsia ", in 1933.
• In clade-based phylogenetic taxonomy, Ceratopsia is often defined to include all marginocephalians more closely related to " Triceratops " than to " Pachycephalosaurus ".
• Although poorly known, " Ceratops " is important in the history of dinosaurs, since it is the type genus for which both the Ceratopsia and the Ceratopsidae have been named.
• Perhaps best known to laypeople were the horned dinosaurs called Ceratopsia of the Cretaceous Period, which were restricted to Asia and western North America ( which were connected for much of this era ).
• In 2011, cladistic analysis performed by Butler " et al . " showed that " Stenopelix " is a basal member of the Ceratopsia, and its sister taxon is " Yinlong ".
• Although John Bell Hatcher had been one of Marsh's workers and therefore in the'Yale Camp'of the Bone Wars, the rivalry between Cope and Marsh, after the death of both he was invited to complete Marsh's monograph on the Ceratopsia also using Cope's material.
