Marília Formation

Trigonosaurus (meaning "triangle lizard" after Triangulo Mineiro, where it was found), 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 originally believed to have come from the same individual. However, one specimen was described as the holotype of Caieiria in 2022, while the holotype may have instead come from Baurutitan. Before its description, it

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.

Uberabasuchus ("Uberaba crocodile") is an extinct genus of crocodylomorph from the Late Cretaceous Serra da Galga Formation of Brazil. It appears to have a high skull like that of the sebecosuchians, but differs from them in having teeth with circular cross-section. Thus, rather than slicing flesh and blood vessels, it is likely to have inflicted powerful crushing bites . The post-crania and the geology suggesting an arid climate indicate that Uberabasuchus was likely a terrestrial predator.

Peirosaurus is an extinct genus of peirosaurid crocodylomorph known from the Late Cretaceous period (late Maastrichtian stage) of Minas Gerais, southern Brazil. It contains a single species, Peirosaurus torminni. It is the type genus of the family Peirosauridae.

Itasuchus is an extinct genus of crocodyliforms from the Late Cretaceous of Brazil. Fossils of the type species I. jesuinoi, first described in 1955 by Llewellyn Ivor Price, have been found from the Marília Formation, though later finds also support its presence in the sediments of the Presidente Prudente Formation.
