Short summary
This paper gives an overview, preliminary results, and perspectives of a drilling project in northeastern Brazil. It presents a promising new record of mid-Cretaceous rocks from the South Atlantic Ocean, which may have registered significant geologic events that affected the distribution of marine ecosystems, as well as major paleoclimatic events. It is also important to assess if a correlation exists between the biotic assemblages of the South Atlantic Ocean and the Tethys Sea.
