The marine influence in the Aptian-Albian of the Araripe Sedimentary Basin, has always been suggested from fossils of several different taxonomic groups. Although the Romualdo Formation presented fossil assemblages of these invertebrates, relevant for the indication of this marine influence during the Aptian-Albian, they spent many years without receiving appropriate studies. Only after the recent work done with both the equinoids and the molluscs represented there allowed the paleoecological…
