Results are presented of a high-resolution study of foraminifers, ostracods and marine palynomorphs from the continuous succession of Middle Volgian – Lower Valanginian (Upper Jurassic to Lower Cretaceous) deposits of the Nordvik section (NE Siberia). Six foraminiferal and six dinoflagellate cyst (dinocyst) zones and subzones have been identified. Volgian foraminiferal assemblages (Dorothia tortuosa JF51 zone and Ammodiscus veteranus, Evolutinella emeljanzevi JF52 zone) may be regarded as correlative markers for Arctic regions as they are also observed in Barents Sea shelf sediments and different regions of Siberia. Marine palynomorph assemblages provide a reliable correlation with northern areas of Western Europe and Canada at three stratigraphic levels: (a) the base of the Upper Volgian, (b) the middle of the Berriasian and (c) the lowermost Valanginian.
