Abstract. Ten sediment samples from Upper Oxfordian strata of Skye and six from the uppermost Lower Oxfordian of southern Dorset were processed for palynomorphs. Of the dinoflagellate cysts recognized, the genus Furzidinium and species F. sentum, Cleistosphaeridium sarmentum and Prolixosphaeridium floccum are described for the first time. The new combination Polygonium bavarica is proposed and Cleistosphaeridium ehrenbergii is retained.
