Calcareous nannofossils from the Boreal upper Campanian-Maastrichtian Chalk of Denmark

Abstract

Boreal calcareous nannofossil assemblages have been documented from three sections in Denmark. from the Upper Campanian to Upper Maastrichtian (nannofossil zones UC16a(BP) to UC20d(BP)): the Stevns-1 borehole, next to the Cretaceous/Palaeogene boundary section of Stevns Klint, eastern Sjaelland, the Rordal-1 borehole and the Rordal quarry section, North Jylland. The moderately-preserved nannofossil assemblages consist of a total of 138 species, comprising several rarely-documented species. several species that were recently described from lower latitudes, two new species of heterococcolith (Prediscosphaera borealensis, Tranolithus stemmerikii). and one new combination (Staurolithites dicandidula).
