[D] Gondwanatitan faustoi [sG] [T]
Kellner & de Azevedo, 1999
Saurischia Sauropodomorpha Sauropoda Titanosauria
Bauru Basin, Alvares Machado region (State of São Paulo) Brazil
Genus - Typespecies
The 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 Álvares Machado region (State of São 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 phylogenetic 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 and Andesaurus, 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.\\\"
