The Tremembé Formation located within the Taubaté Basin in the state of São Paulo.[1]

Geology

[edit]

The formation is characterized by lacustrine deposits[2] which were laid down during the Oligocene.[3]

Paleontology

The Tremembé Formation contains many fossils which are of interest to paleontologists.[1][4] Fish are particularly well preserved.[5] Among other mammals significant Sparassodonta and Proborhyaenidae finds have been made.[6]
