Figure 3. Comparison of the sequence of last occurrences in Hole 985A, Hole 643A (Vøring Slope), and in quantitative biozonation of the Vøring Plateau and northern North Sea (Norwegian margin) of Gradstein and Bäckström (1996). Taxonomic names are listed in order of their stratigraphic occurrence and have been updated to facilitate comparison. The species given in bold occur at the top of the Eocene succession.
