Uberaba Formation
The Uberaba Formation is part of the Bauru Group. It is located in Uberaba, Minas Gerais State. This formation has yielded only disarticulated dinosaur specimens. Santucci (2002) noted that sauropod remains from the Uberaba Formation represent possibly basal titanosaurs.

Description:
A new titanosaurid, Baurutitan britoi n. gen., n. sp., is described and compared with other taxa
of that sauropod clade. The specimen (MCT 1490-R) consists of the last sacral followed by a sequence of 18 caudal vertebrae that were found in the continental deposits of the Late Cretaceous Bauru Group that outcrop at the Peirópolis region, near the town of Uberaba, State of Minas Gerais, Brazil. This new taxon is distinguished from other titanosaurians by several features, including subrectangular to square outline of the anterior articulation surface of the anterior and middle caudals, strongly pointed laterally directed process intercepting the spinoprezygapophyseal lamina in caudal 1; dorsal prezygapophyseal tuberosity on the lateral margin of the prezygapophyses of caudals 2-4, that smoothens out in midcaudals. This material
demonstrates that the horizontal ridge present in middle and posterior caudals of some titanosaurs, in Baurutitan britoi is homologous with a dorsal tuberosity and not with the transverse process.

Arquivos do Museu Nacional, 63(3):565-593. Downloadable PDF
Description:
A new titanosaurid dinosaur from the Late Cretaceous continental deposits of the Bauru Group
is described. Trigonosaurus pricei n.gen., n.sp., is based on two specimens, both collected at the Caieira Quarry near Peirópolis, Minas Gerais. The holotype consists of the five most posterior cervical vertebrae, 10 dorsals, six sacrals and the left ilium (MCT 1488-R). The second specimen (paratype) consists of 10 caudal vertebrae that according to a quarry map, were found isolated but show a similar morphology and compatible size suggesting that they belonged to one individual (MCT 1719-R). Trigonosaurus pricei is diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals. The occurrence of this new taxon indicates a higher diversity of titanosaurids in the Brazil during the Cretaceous period.

Place: Adamantina Formation, Serra da Boa Vista, Minas Gerais State;
Time: Maastrichtian, Late Cretaceous;
Size: 13 meters-long;
Taxonomy: Saurischia, Sauropodomorpha, Sauropoda, Titanosauria, Saltasauridae;
Etymology: from Maxakali, ethnic group present in the Minas Gerais State where this fossil was found. The specific name is from Topa, a deity worshiped by the Maxakali people.

Description:
It is the biggest dinosaur found in Brasil, a titanosaur characterized by the following combination of features: tail composed of anterior and midposterior caudal vertebrae with the anterior (and posterior) surface of the centrum dorsoventrally compressed; midposterior caudal vertebrae with the lateral surface of the centrum strongly concave (spool-shaped); dorsal margin of neural spine in midposterior caudal vertebrae inclined anteriorly; presence of at least one midposterior caudal with biconvex centrum; metacarpal IV about 12% shorter than metacarpal II; sacral centrum with keel-shaped ventral surface. Associated material – The distal end of a right scapula (MN 7048-V) and two sternal plates (MN 7049-V and MN 7050-V) of a second animal attributed to Maxakalisaurus
topai, one caudal vertebra (MN 7051-V) that may or not pertain to this species, and crocodylomorph and theropod teeth.
