Description

edit

This rock formation is located in the geopark of Paleorrota, and is located to the south of another geopark. The formation dates to 249 million years ago and belongs to the Lower Triassic.[2]

The Sanga do Cabral Formation is correlated with the "impoverished zone" (Procolophon subzone) of the Lystrosaurus Assemblage Zone of the Karoo Basin of South Africa by some authors on the basis of the abundant records of Procolophon.
