We summarized here the hitherto known Late Cretaceous vertebrate record of the Triângulo Mineiro (west portion of Minas Gerais State, southeastern Brazil). All specimens come from the Bauru Group (Bauru Basin) from the Adamantina (Campanian), Uberaba (Campanian) and Marília (Maastrichtian) formations. Vertebrate-bearing sites are distributed along the Triângulo Mineiro, but the Uberaba County has the largest diversity of Late Cretaceous vertebrate from the Bauru Group, mainly concentrated into the Serra da Galga Member of the Marília Formation. At present, the following taxa were recognized at 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 Marília Formation: Ceratodus sp. (Dipnoi), Vidalamiine indet. (Amiiformes), Lepisosteiformes indet., Siluriformes indet., Characiformes indet., Perciformes indet., Baurubatrachus pricei and Uberabatrachus carvalhoi (Neobachachia), Cambaramys langertoni, Peiropemis 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., Aviale indet., and Enantiornithes indet. The Triângulo Mineiro region has a great paleontological potential which will generate future results amplifying the diversity and knowledge of Late Cretaceous vertebrates of Brazil.
