Foraminiferal bioevents in the upper Campanian to lowest Maastrichtian of the Middle Vistula River section, Poland

The Upper Campanian–Lower Maastrichtian interval of the Middle Vistula River Valley section records the following benthic foraminiferal bioevents in ascending stratigraphical order: LO of Globorotalites michelinianus, FO and LO of Globorotalites emdyensis (=G. hiltermanni), FO of Bolivina incrassata, FO of Bolivinoides miliaris, FO of Angulogavelinella gracilis (=A. bettenstaedti), LO of Gavelinella monterelensis, FO of Osangularia navarroana, FO of Bolivina decurrens and FO of Neoflabellina reticulata. These events are recorded in very similar stratigraphic positions in the Lägerdorf-Kronsmoor succession (northern Germany) and in the succession of eastern England and, at least some of them, in eastern Europe. Accordingly they can serve as important markers for stratigraphic correlation across Europe. The FOs of the planktonic species, Rugoglobigerina milamensis, R. hexacamerata and R. pennyi, in the uppermost part of the “Inoceramus” redbirdensis Zone,are very close to the Campanian–Maastrichtian boundary as defined by inoceramid bivalves (Walaszczyk, 2004) and we propose these planktonic foraminiferal bioevents as a good proxy for this boundary in temperate regions.
