The Bauru Group is a geological group of the Bauru Sub-basin, Paraná Basin in Minas Gerais, São Paulo, General Salgado, Itapecuru-Mirim, Mato Grosso, Brazil whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1]
Subdivisions
The Bauru Group was divided by Fernandes and Coimbra (1996) in four formations, namely Adamantina, Uberaba, Araçatuba and Marília.[2] In 1998, Fernandes revised the group and recognize six formations, Uberaba, Vale do Rio do Peixe, Araçatuba, São José do Rio Preto, Presidente Prudente and Marília.[3] The Adamantina Formation was divided in Vale do Rio do Peixe, São José do Rio Preto and Presidente Prudente Formations.[3]
