We summarize here the Late Cretaceous vertebrate record of the Triângulo Mineiro (western portion of the Minas Gerais State, southeastern Brazil). All the specimens come from the Bauru Group (Bauru Basin) from the Adamantina (Campanian), Uberaba (Campanian) and Marilia (Maastrichtian) formations. Vertebrate-bearing sites are distributed throughout the Triângulo Mineiro, but the Uberaba County has the largest diversity of Late Cretaceous vertebrate from the Bauru Group, mainly concentrated in the Serra da Galga Member of the Marilia Formation. So far, the following taxa have been recognized in the Triângulo Mineiro, from the Adamantina Formation: Amiiformes indet., cf. Atractosteus sp. (Lepisosteiformes), Mesoeucrocodylia indet., Sphagesaurus sp. (Sphagesauridae), Campinasuchus dinizi and Pissarrachampsa sera (Baurusuchidae), Maxakalisaurus topai (Titanosauria), Titanosauria indet., and Abelisauridae indet.; from the Uberaba Formation: Titanosauria indet. and Megaraptora indet.; from the Marilia Formation: Ceratodus sp. (Dipnoi), Vidalamiine indet. (Amiiformes), Lepisosteiformes indet., Siluriformes indet., Characiformes indet., Perciformes indet., Baurubatrachus pricei and Uberabatrachus carvalhoi (Neobatrachia), Cambaremys langertoni, Peiropemys mezzalirai and Pricemys caiera (Podocnemididae) and Podocnemididae indet., Pristiguana brasiliensis (Iguania), Itasuchus jesuinoi (Trematochampsidae), Labidiosuchus amicum (Notosuchia), Peirosaurus torminni and Uberabasuchus terrificus (Peirosauridae), Trigonosaurus pricei, Baurutitan brittoi, Uberabatitan ribeiroi, Aeolosaurini indet. (Titanosauria), Abelisauroidea indet., Abelisauridae indet., cf. Carcharodontosauridae indet., Maniraptora indet., Avialae indet., and Enantiornithes indet. The Triângulo Mineiro region has a great paleontological potential which will generate future results amplifying the diversity and knowledge of the Late Cretaceous vertebrates of Brazil.
