Plateosauridae is a family of plateosaurian sauropodomorphs. Plateosaurids were early sauropodomorph dinosaurs which existed in Asia, Europe and South America during the Late Triassic period. Although several dinosaurs have been classified as plateosaurids over the years, a 2007 study by Adam M. Yates found only Plateosaurus and Unaysaurus valid plateosaurids. In another study, Yates merged Sellosaurus into Plateosaurus. In 2011, Jaklapallisaurus, a plateosaurid from India was named.
