Baurutitan is a genus of sauropod dinosaur that lived during the Late Cretaceous in what is now Brazil. The type species, Baurutitan britoi, was described in 2005 by Kellner and colleagues, although the fossil remains had already been discovered in 1957. Baurutitan is classified as a lithostrotian titanosaur, and is distinguished from related genera based on its distinctive caudal vertebrae. This South American dinosaur was found in the Serra da Galga Formation near Uberaba, in the Brazilian state of Minas Gerais.
Trigonosaurus, is a genus of saltasaurid dinosaurs from the Maastrichtian Serra da Galga Formation of Brazil. The type species, Trigonosaurus pricei, was first described by Campos, Kellner, Bertini, and Santucci in 2005. It was based on two specimens, both consisting mainly of vertebrae. The two specimens were believed to have come from the same individual. However, one specimen was described as the holotype of Caieiria in 2022. Before its description, it was known as the "Peirópolis titanosaur", after the place it was found.
Maxakalisaurus is a genus of titanosaur dinosaur, found in the Adamantina Formation of Brazil, in the state of Minas Gerais in 1998. The genus name is derived from the tribe of the Maxakali; Topa is one of their divinities.
Mariliasuchus is an extinct genus of Late Cretaceous notosuchian mesoeucrocodylian found near Marilia, Brazil. The first bone remains were found and collected in 1995 by Brazilian paleontologist William Nava, in red rocks from the fossiliferous Adamantina Formation. Four years later, it was described as Mariliasuchus amarali, by Brazilian paleontologists Ismar de Souza Carvalho and Reinaldo J. Bertini.
Adamantinasuchus is an extinct genus of notosuchian crocodylomorph from and named after the Late Cretaceous Adamantina Formation of Brazil. It is known from only one fossil, holotype UFRJ-DG 107-R, collected by William Nava. The fossil consists of a partial skull, fragmentary limb bones and a few broken vertebrae, and was found 25 km SW of the town of Marilia, near a reservoir dam. Adamantinasuchus was approximately 60 cm long from nose to tail, and would have only weighed a few kilograms.
Sphagesaurus is an extinct genus of sphagesaurid notosuchian crocodylomorph from the Late Cretaceous of southwest São Paulo, southern Brazil.
Peirosaurus is an extinct genus of peirosaurid crocodylomorph known from the Late Cretaceous period of Minas Gerais, southern Brazil. It contains a single species, Peirosaurus torminni. It is the type genus of the family Peirosauridae.
Yacarerani is an extinct genus of Late Cretaceous notosuchian crocodylomorph. Fossils have been found in 2002 in the Cajones Formation in Amboró National Park of central Bolivia and are Turonian-Santonian in age. The genus was described in 2009 in the Journal of Vertebrate Paleontology. The material represents two individuals and was found in association with eggs that are thought to have been part of a nest. Yacarerani was a small crocodylomorph at around 80 centimetres (31 in) in length. It may have lived in small groups, creating burrows to lay eggs in.
Stratiotosuchus is an extinct genus of baurusuchid mesoeucrocodylian from the Adamantina Formation in Brazil. It lived during the Late Cretaceous. The first fossils were found in the 1980s, and the type species Stratiotosuchus maxhechti was named in 2001. A hyperpredator, it and other baurusuchids may have filled niches occupied elsewhere by theropod dinosaurs.
Pepesuchus is an extinct genus of carnivorous metasuchian from the Late Cretaceous period. It is a peirosaurid which lived during the Campanian and Maastrichtian stages of the Late Cretaceous in what is now state of São Paulo, Brazil.
Campinasuchus is an extinct genus of baurusuchid mesoeucrocodylian from Minas Gerais State of Brazil.
Pissarrachampsa is an extinct genus of baurusuchid mesoeucrocodylian from the Late Cretaceous of Brazil. It is based on a nearly complete skull and a referred partial skull and lower jaw from the ?Campanian - ?Maastrichtian-age Vale do Rio do Peixe Formation of the Bauru Group, found in the vicinity of Gurinhatã, Brazil.
Caipirasuchus is an extinct genus of sphagesaurid notosuchians known from the Late Cretaceous of northern São Paulo State, southeastern Brazil. The type species, C. paulistanus, was named in 2011. A second species, C. montealtensis, was referred to Caipirasuchus in 2013 after having been named in 2008 as a species of Sphagesaurus. A third species, C. stenognathus, was described in 2014. A fourth species, C. mineirus, was described in 2018. A fifth species, C. attenboroughi, was named in 2021 in honour of David Attenborough.
Caryonosuchus is an extinct genus of sphagesaurid notosuchian known from the Late Cretaceous of São Paulo State, southeastern Brazil.
Sahitisuchus is an extinct genus of sebecid mesoeucrocodylian known from Rio de Janeiro State of southeastern Brazil. It contains a single species, Sahitisuchus fluminensis. It is a terrestrial sebecid, however also adopted to a semi-aquatic lifestyle to some degree, most probably coexisting with the semi-aquatic alligatorid Eocaiman itaboraiensis.
Ypupiara is an extinct genus of unenlagiine theropod from the Late Cretaceous Serra da Galga Formation of Brazil. It was the first member of the Dromaeosauridae to be discovered in South America and the first member of the Unenlagiinae to be discovered, but not the first to be identified as such. The type and only species, Y. lopai, is known solely from a specimen that was destroyed in a fire in 2018.
Antaeusuchus taouzensis is a species of peirosaurid notosuchian from the Late Cretaceous Kem Kem Group of Morocco. It was described in 2021, and it is the only species in the genus Antaeusuchus. It is the fourth notosuchian described from the region and the second Kem Kem peirosaurid after Hamadasuchus.
Barrosasuchus is a genus of peirosaurid notosuchian from the Santonian of Argentina and part of the extensive peirosaurid record of Late Cretaceous Patagonia. It contains one species, Barrosasuchus neuquenianus. B. neuquenianus is known from an almost complete skull and the majority of the articulated postcranial skeleton, making it the best preserved Patagonian peirosaurid.
Kyhytysuka is an extinct genus of ophthalmosaurian ichthyosaur from Early Cretaceous Colombia. The animal was previously assigned to the genus Platypterygius, but given its own genus in 2021. Kyhytysuka was a mid-sized ophthalmosaurian with heterodont dentition and several adaptations suggesting that it was a macropredatory vertebrate hunter living in shallow waters. It contains a single species, Kyhytysuka sachicarum.
The Serra da Galga Formation is a geological formation in Minas Gerais state of southeastern Brazil. Its strata date back to the Maastrichtian, and are part of the Bauru Group.It was originally considered a member of the Marília Formation.
