Abstract

A new radiolarian genus and species, Joergensenium rotatile, is described. This species is restricted to recent sediments and plankton samples from the North Atlantic. Its recent distribution in the Norwegian Sea and West Norwegian fjords shows a strong affinity to the neritic province and reaches almost 2% in Hryangerfjord. This species is only known from late Glacial and Holocene sediments in the Nordic seas. This genus shows, however, a patchy stratigraphic distribution with its first occurrence in the south-west Pacific within Paleocene, in the Middle to Late Miocene from the Norwegian Sea, and in the Labrador Sea at the base of biozone NN 21. Two fjords are compared for the general radiolarian distribution, but with special emphasis on the occurrence of J. rotatile in both sediment and plankton.
