Integrated foraminiferal biostratigraphy, bioevents and sea‐level reconstruction in the Campanian–Maastrichtian succession at Gabal Nezzazat, south‐western Sinai, Egypt

Abstract

Age assignment: Late Campanian.Van Hinte (1976) discussed the occurrence of B. decoratus in the Campanian type section as being in general agreement with the widely held view that it does not extend above the Campanian. As shown by Barr (1970), the B. decoratus Zone spans the entire Upper Campanian, and not the Lower Campanian as indicated by Van Hinte (1976). | Bolivinoides miliaris ZoneType: Lowest Occurrence Zone. Definition:The lower limit of this zone is marked by the LO of the nominate species, whereas the upper one is defined by the LO of Bolivinoides draco.Benthic foraminiferal association: Beside the index species, the associated diverse benthic foraminifera includes: Bolivinoides rhomboi-
