Abstract K÷the, A., 1996; Dinoflagellatenzysten- und Kalknannoplankton-Untersuchungen im Grenzbereich Eozän/Oligozän am Doberg bei Bünde ('Piepenhagen-Profil', Westfalen). Newsletters on Stratigraphy 33(3): 145-155 Dinocysts and calcareous nannoplankton were investigated from the Brandhorst Formation, the Piepenhagen Formation and the Septarian Clay Formation of the "Piepenhagen Section" near Doberg/B³nde (Westphalia). The formations were dated biostratigraphically in accordance with the international subdivision of the Tertiary. Based on these results, the Eocene/Oligocene boundary level lies within the Brandhorst Formation or at the base of the Piepenhagen Formation, respectively.
