Abstract
SUMMARY: A palynological investigation of the Hettangian to Upper Kimmeridgian strata penetrated by the Nettleton Bottom Borehole yielded 56 genera and 80 species of dinoflagellate cysts, many of which are of biostratigraphical significance. The large stratigraphical extent of the borehole enables the principal changes in dinoflagellate cyst floras throughout the Jurassic System of the East Midlands to be demonstrated. Comparison of the dinoflagellate cyst assemblages with those reported from Europe and other areas, principally Arctic Canada, illustrates marked global provincialism during the Middle Jurassic. Two new species, Endoscrinium asymmetricum sp. nov. and Meiourogonyaulax planoseptata sp. nov. are described from the Upper Bathonian to Lower Callovian and Lower Callovian respectively.This publication has 38 references indexed in Scilit:
