The Maria Farinha Formation is a geological formation of the Parnaíba Basin in Pernambuco, northeastern Brazil whose strata date back to the Danian stage of the Paleocene, or Tiupampan in the SALMA classification.

The formation comprising limestones, dolomites, marly and sandy limestones has been deposited in a shallow marine platform environment.

The formation has provided fossils of reptiles and fish.

Description

The Maria Farinha Formation crops out in the Parnaíba Basin in the northeastern state of Pernambuco of Brazil. The formation registers the Cretaceous-Paleogene boundary at the base of the formation, where it overlies the Maastrichtian Gramame Formation. The 14 metres (46 ft) thick formation is overlain by the Eocene Tambaba Formation which is overlain by the Plio-Pleistocene Barreiras Formation.[1]
