Geologic events related to the opening of the South Atlantic Ocean deeply influenced the sedimentary record of the Araripe Basin. As consequence, upper stratigraphic units of the …
The tectonic evolution of the Equatorial Atlantic Gateway (EAG) throughout the early Cretaceous had global implications. This break-up of western Gondwana has played a …
Abstract The Cretaceous (upper Aptian) Romualdo Formation of the Araripe Basin, northeastern Brazil, is a marine-influenced, predominantly fine-grained siliciclastic unit. In …

Abstract The Ipubi Formation of the Santana Group, Araripe Basin, Brazil, is characterized by black shales and overlying evaporite deposits and is suggested to record the transition from …
The transition between Aptian and Albian stages of the Lower Cretaceous (∼ 113 Ma) was a critical moment in the development of the proto–South Atlantic Ocean. At this time, marine …

The goal of this study is to investigate the Aptian–lower Albian microfossil association present in the Romualdo Formation, Araripe Basin, Pernambuco State, northeastern Brazil …
Abstract The Aptian Romualdo Formation (Araripe Basin, NE Brazil) was deposited in a restricted epeiric sea, during the opening of the South Atlantic Ocean, with a coeval record to …
Abstract The Aptian Romualdo Formation is a siliciclastic-dominated sedimentary unit recording the last marine ingression within the Cretaceous interior basins of northeastern …
The Tonnoidea is a moderately diverse group of large, predatory gastropods with∼ 360 valid species. Known for their ability to secrete sulfuric acid, they use it to prey on a diversity …
