New dinocyst taxa from the Eocene of the North Sea
Abstract. Dinoflagellate cysts (dinocysts) are abundant in the Eocene of the North Sea and provide a high-resolution biostratigraphic zonation. Twelve species are erected to accommodate zonal markers that have not been previously described. These are Areosphaeridium ebdonii, Areosphaeridium michoudii, Cerebrocysta magna, Diphyes brevispinum, Diphyes pseudoficusoides, Hystrichosphaeropsis costae, Hystrichostrogylon clausenii, Membranilarnacia compressa, Phthanoperidinium clithridium, Phthanoperidinium distinctum, Phthanoperidinium powellii and Phthanoperidinium regalis.
