Genera[1]

Massospondylidae is a family of early massopod dinosaurs[3][4] that existed in Asia, Africa, South America and Antarctica[5] during the Late Triassic to the Early Jurassic periods. Several dinosaurs have been classified as massospondylids over the years. The largest cladistic analysis of early sauropodomorphs, which was presented by Apaldetti and colleagues in November 2011, found Adeopapposaurus, Coloradisaurus, Glacialisaurus, Massospondylus, Leyesaurus and Lufengosaurus to be massospondylids.[6] This result supports many previous analyses that tested fewer taxa.[4][7][8][9] However, this analysis found the two recently described North American massopods, Sarahsaurus and Seitaad, and the South African Ignavusaurus to nest outside Massospondylidae, as opposed to some provisional proposals.[10][11] Earlier in 2011, Pradhania, a sauropodomorph from India, was tested for the first time in a large cladistic analysis and was found to be a relatively basal massospondylid.[2] Mussaurus and Xixiposaurus may also be included within Massospondylidae.[12]

Phylogeny

Massospondylidae, which was first named by Huene in 1914, is a stem-based taxon. It was defined by Sereno as all animals more closely related to Massospondylus carinatus than to Plateosaurus engelhardti and Saltasaurus loricatus.[13]
