Selected Cribroperidinium species (Dinophyceae) from the Kimmeridgian and Volgian of northwest Europe
Abstract. Two new dinoflagellate species, Cribroperidinium complexum and C. erymnoseptum are described from the Kimmeridgian of the Norwegian Continental Shelf and Spitzbergen. The morphotypes described as Cribroperidinium sp. A by Davey (1982) from the Portlandian of Denmark, are thought to be conspecific with Cribroperidinium gigas Raynaud 1978. The holotype of Cribroperidinium longicorne (Downie) Lentin & Williams 1985 has been examined and is discussed.
