Gravisauria
Gravisauria is a clade of sauropod dinosaurs consisting of ''Vulcanodon'' and Eusauropoda.〔Allain, R. and Aquesbi, N. (2008). "Anatomy and phylogenetic relationships of ''Tazoudasaurus naimi'' (Dinosauria, Sauropoda) from the late Early Jurassic of Morocco." ''Geodiversitas'', 30(2): 345-424.〕
==Classification==
The clade Gravisauria was appointed by the French paleontologist Ronan Allain and Moroccan paleontologist Najat Aquesbi in 2008 when a cladistic analysis of the dinosaur found by Allain, ''Tazoudasaurus'', as the outcome was that the family Vulcanodontidae. The group includes ''Tazoudasaurus'' and ''Vulcanodon'', and the sister taxon Eusauropoda, but also certain species such as ''Antetonitrus'', ''Gongxianosaurus'' and ''Isanosaurus'' that do not belong in Vulcanodontidae but to an even more basic position occupied in Sauropoda. It made sense to have Sauropoda compared to this, more derived group that included Vulcanodontidae and Eusauropoda in a definition: Gravisauria (heavy lizards), defined as the group formed by the last common ancestor of ''Tazoudasaurus'' and ''Saltasaurus'' (Bonaparte and Powell, 1980) and all its descendants.〔
