摘要: Abstract Three dinoflagellate cysts species are formally described from Selandian and Danian sedimentary rocks of the North Sea Norwegian Sea. The taxa well known within regional biostratigraphy community as important age markers, but have never been described. Thalassiphora lacunata sp. nov. differs delicata by possessing large, subcircular openings on dorsal surface periphragm. For Spiniferites magnificus nov., morphology processes development high sutural crests main diagnostic features to distinguish this other genus Spiniferites. Operculodinium magnum its larger size thicker wall, also distinctive numerous solid, fibrous processes. O. a stratigraphic range restricted Danian. has short mainly early Selandian.
