Caiuá Formation
From Wikipedia, the free encyclopedia
Not to be confused with Caiuá Group.
The Caiuá Formation is an Early Cretaceous geologic formation in Brazil and Paraguay. Fossil theropod tracks have been reported from the formation.[1] The formation, the lowermost unit of the Bauru Group, was deposited in the Barremian and Aptian epochs of the Early Cretaceous, around 130 to 120 Ma. The formation is unconformably overlain by the Santo Anastácio Formation and the unconformity probably represents the start of the opening of the South Atlantic and the formation of the Santos Basin.[2]
