Genera

Aeolosauridae is an extinct family of titanosaurian dinosaurs known from the late Cretaceous period of Argentina and Brazil. Thomas Holtz (2011) assigned Adamantisaurus, Aeolosaurus, Gondwanatitan, Muyelensaurus, Panamericansaurus, Pitekunsaurus and Rinconsaurus to Aeolosauridae.[1] Rodrigo M. Santucci and Antonio C. de Arruda-Campos (2011) in their cladistic analysis found Aeolosaurus, Gondwanatitan, Maxakalisaurus, Panamericansaurus and Rinconsaurus to be aeolosaurids.[2]

Phylogeny

Aeolosaurini was defined by Franco-Rosas, Salgado, Rosas and Carvalho (2004) as the stem-based taxon that corresponds to the most-inclusive clade containing Aeolosaurus rionegrinus and Gondwanatitan faustoi, but not Saltasaurus loricatus and Opisthocoelicaudia skarzynskii. Below is a cladogram showing the phylogenetic relationships of Aeolosaurini from Santucci and Arruda-Campos (2011).[2]
