Impagidinium obscurum sp. nov., a Marker Dinoflagellate Cyst for the Thanetian (Paleocene) of the North Sea and the Barents Sea
This paper presents the formal description of Impagidinium obscurum sp. nov. from the Thanetian strata of northwest Europe. The palaeogeographic distribution of this species covers a wide area, ranging from the North Sea to the Barents Sea. Palynologists working in the region have long referred to I...
