摘要: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
