Stratigraphy comments: Lower Cretaceous Recôncavo Basin, Bahia Supergroup, Ilhas Group (Late Hauterivian–Early Barremian)

"no exact stratigraphic precedence was recorded by Mawson. Rocks from the Recôncavo Basin, Bahia Supergroup, crop out in those localities. The formations from which the material could have come have all been dated as Lower Cretaceous, based on microfossils (Viana et al., 1971)." (Rodrigues & Kellner 2010)
