Plateosauria is a suborder sauropodomorpha, lived during the late Triassic to the Late Cretaceous period. Plateosauria by Gustav Tornie proposed in 1913. By the 1980s, Plateosaurus rarely used this term, until a new generation of paleontologists began to re-use it. Plateosauria contains plateosauridae and the famous Plateosaurus, and belong to the prosauropoda. Peter M. Galton and Paul Upchurch also included Coloradisaurus, Euskelosaurus, Lufengosaurus, Jingshanosaurus, Massospondylus, Mussaurus, Sellosaurus, and Yunnanosaurus. Some paleontologists believe Massospondylus its relatives belonging to another independent family, Massospondylidae.
