Riassunto / AbstractA new titanosaur, Gondwanatitan faustoi n. gen., n. sp., is described and compared with other members of that sauropod clade. The specimen consists of an incomplete skeleton (MN 4111-V) that comes from the Alvares Machado region (State of Sao Paulo, Brazil) and was found in the continental deposits of the Late Cretaceous Bauru Group. This new taxon has the following autapomorphies : distal articular surfaces of proximal and mid caudals "heart-shaped"; deltopectoral crest of humerus very well developed and curved medially, tibia with anterior part of the proximal articulation projecting dorsally and cnemial crest only slightly curved laterally. Although its phylogenetical position is not clear, this new taxon is not closely related to members of the Saltasaurinae and can also be distinguished from more basal titanosaurs like Andesaurus and Malawisaurus. It shares at least one unique character with Aeolosaurus, a strongly anteriorly directed neural spine of the anterior and anterior midcaudals, but more material of both taxa is needed to confirm a close relationship
