Detailed nannofossil biostratigraphy of the cored upper Maastrichtian – Danian section of the E-5X well was carried out as part of the PhD study ‘Upper Maastrichtian – Danian nannofossils of the Danish Central Graben and the Danish Basin: a combined biostratigraphic – palaeoecological approach’ (Sheldon 2006). The E-5X well was drilled in 1991 as an appraisal well on the Tyra-SE Field in the Danish Sector of the North Sea (Figure 1). The following report presents a biostratigraphic breakdown of the cored chalk section of the well, based on nannofossils.
