Subdivisions

According to a 2016 study:
The Bauru Basin covers an area of approximately 379.362 km2 located almost exclusively in Brazil.., with selected outcrops in Northeastern Paraguay. This Cretaceous sedimentary succession reflects changing nonmarine environments, such as eolian, lacustrine, fluvial and alluvial fans.

The Bauru Group was divided by Fernandes and Coimbra in four formations, namely Adamantina, Uberaba, Araçatuba and Marília. In 1998, Fernandes revised the group and recognize six formations, Uberaba, Vale do [Rio do Peixe Formation|Vale do Rio do Peixe], Araçatuba, São José do [Rio Preto Formation|São José do Rio Preto], Presidente [Prudente Formation|Presidente Prudente] and Marília. The Adamantina Formation was divided in Vale do Rio do Peixe, São José do Rio Preto and Presidente Prudente Formations.
