Abstract

The Jatobá Basin, part of the Recôncavo-Tucano-Jatobá rift has been stratigraphically correlated to the Araripe Basin. Both basins were deposited during the South Atlantic opening process that culminated in the separation between South America and Africa. Although there is an abundance of works related to the Araripe Basin, the same does not occur with the Jatobá Basin, which until now had records of fossil bivalves only in the Inajá Formation (Late Devonian) and the Romualdo Formation (Aptian). The presence of the Salvador Formation (Berriasian Late) was recently describe in Jatobá Basin, which occured only in Recôncavo and Tucano Basins until now. This work aims to bring a systematic classification of the bivalves collected supposedly in this formation by the CPRM. (AU)
