Uberaba Formation
The Uberaba Formation is a Campanian geologic formation belonging to the Bauru Group of the Bauru Sub-basin, Paraná Basin located in Minas Gerais state of southeastern Brazil. The Uberaba Formation, intercalating the fossiliferous older Adamantina and younger Marília Formation, comprises limestones, sandstones, and conglomerates, often cemented by calcite with volcaniclastic sediments.[1] The formation interfingers with the Adamantina Formation.[2]

Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[3] A megaraptoran similar to Aerosteon is known from the formation.[4]
The crocodylomorph Uberabasuchus was described from the overlying Marília Formation.
