摘要：A new study based on calcareous nannofossil and benthicand planktonic foraminifer biostratigraphy is presented forthe upper Campanian – Maastrichtian chalk of the FemernBælt (Denmark and Germany; Fig.1). Te results are consistent with recent studies of the Danish chalk for this interval,allowing correlation across the Danish Basin and forming thebasis for correlation further afeld within the Boreal Realm.Numerous studies have been carried out recently on the upper Campanian – Maastrichtian chalk of the Danish Basin,covering aspects such as sedimentology, depositional environment, macrofossil biostratigraphy, carbon isotope stratigraphy as well as nannofossil and dinoﬂagellate biostratigraphy. However, very few published studies on foraminifersexist across this interval in this area. Te 09.A.006, 09.A.007and 09.A.008 boreholes (Fig. 2) were drilled in 2009 in preparation for construction of a fxed link across the FemernBælt, which will connect Denmark to Germany (RambøllArup JV 2011). Te boreholes penetrated glacial till, Paleocene–Eocene clay and chalk (Sheldon et al. 2012). Here, forthe frst time, the Boreal foraminifer biostratigraphy of thelate Campanian – Maastrichtian interval is investigated andpresented alongside nannofossil biostratigraphy.
