List Of Dinosaur ClassificationsThis article contains a list of dinosaur classifications. Textbook classification The following schema is based on the third edition of Vertebrate Paleontology (Benton, 2004), a respected college textbook. While it is structured as a cladogram (evolutionary tree), it also retains the traditional ranks used in Linnaean taxonomy. The classification has been updated from the second edition in 2000 to reflect new research, but remains fundamentally conservative. Benton classifies all dinosaurs within the Series Amniota, Class Sauropsida, Subclass Diapsida, Infraclass Archosauromorpha, Division Archosauria, Subdivision Avemetatarsalia, Infradivision Ornithodira, and the Superorder Dinosauria. Dinosauria is then divided into the two traditional orders, Saurischia and Ornithischia. The dagger (†) is used to indicate taxa with no living members. Order Saurischia †Order Ornithischia Another scheme Dinosaurs are divided into two major orders, the Saurischia and the Ornithischia, on the basis of hip structure.
