  Uberaba Formation (Brazil) | |
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.
