Unusually large Late Campanian – Early Maastrichtian foraminifera from the Southern North Sea Basin
Abstract. A low diversity fauna of unusually large (individuals of two to three times the normal size) agglutinated and calcareous benthic foraminifera is recorded from the Late Campanian – Early Maastrichtian Chalk sequences of two boreholes (Shell 49/19.1 and Shell 49/20.2) in the Southern North Sea Basin. Associated planktonic species are extremely rare. This distinctive assemblage provides a useful local stratigraphical marker.
