Description
Summary:The description of new titanosaur specimens unearthed from deposits of the Serra da Galga Formation (Bauru Group, Late Cretaceous) at the BR-262 site, near Peirópolis (Uberaba, Minas Gerais State, Brazil), sheds light on the taxonomy of two taxa previously known from the same area and geological unit: and . A comparative revision indicates that represents a junior synonym of , and that the BR-262 specimens belong to that latter species. The information provided by the new specimens also revealed that the paratype of (MCT 1719-R), a caudal vertebral series, actually represents a new taxon, named here as gen. et sp. nov.
