Dinoflagellate cyst and spore-pollen spectra from the Lower Oligocene Krabbedalen Formation at Kap Brewster, East Greenland

Shallow-marine deposits of the Krabbedalen Formation (Kap Dalton Group) from Kap Brewster, central East Greenland, yielded rich dinoflagellate cyst and pollen-spore assemblages. Previously, this formation yielded also rich mollusc and foraminifer age-diagnostic assemblages. A Lower Oligocene age of the Krabbedalen Formation seems to be supported by the dinoflagellate cyst assemblage analysis, while the pollen-spore assemblages point to a wider stratigraphic age range within Oligocene-Middle Miocene.
