Santana Formation, Geological formation in Pernambuco, Brazil

The Santana Formation contains horizontal calcareous beds mixed with shales, siltstones, and sandstones within the Araripe Basin of northeastern Brazil.

Johann Baptist von Spix first documented the fossiliferous record of the region in 1819, noting fish fossils in calcareous concretions and limestones.

The formation holds extensive collections of preserved fossils, including pterosaurs, fish, insects, and plants from the Early Cretaceous period.

Local mining activities extract limestone for cement and construction materials, while researchers conduct regular paleontological studies in designated excavation areas.

The limestone nodules formed around deceased organisms preserved soft tissue details, enabling scientists to study ancient predator-prey relationships.
