New dinoflagellate cyst species from Cretaceous/Palaeogene boundary deposits at Ouled Haddou, south-eastern Rif, Morocco

A palynological investigation of the recently described and foraminifera-dated Ouled Haddou section (south-eastern Rif Corridor) in northern Morocco yielded eight new dinoflagellate cyst species within a rich and well-preserved assemblage as follows: Batiacasphaera rifensis, Cerodinium mediterraneum, Damassadinium spinosum, Eisenackia msounensis, Impagidinium maghribensis, Lejeunecysta izerzenensis, Pterodinium cretaceum and Ynezidinium tazaensis. They are described because they are likely to be important for recognition of the Cretaceous/Palaeogene boundary elsewhere in Morocco and at other locations.
