Marília Formation

The Marilia Formation is part of the Bauru Group. It's named after Marilia, Sao Paulo State, but it included locations in Minas Gerais and Goias State too. Its age is dated from Upper Maastrichtian, in Latest Cretaceous.

A Formação Marília é parte do Grupo Bauru. Apesar de nomeada a partir de terrenos situados no município de Marília, Estado de São Paulo, apesar de incluir sítios nos estados de Minas Gerais e Goiás. Sua idade é considerada como do Maastrichtiano Superior, a última divisão do período Cretáceo.

Uberaba Formation

The Uberaba Formation is part of the Bauru Group. It is located in Uberaba, Minas Gerais State. This formation has yielded only disarticulated dinosaur specimens. Santucci (2002) noted that sauropod remains from the Uberaba Formation represent possibly basal titanosaurs.
