PLANT FOSSILS FROM THE WRITHLINGTON-GEOLOGICAL-NATURE-RESERVE

This is currently the best locality for upper Westphalian D plant foss ils in the Radstock Basin, one of the classic areas for studying the p alaeobotany of this age. The assemblage includes a diverse range of gy mnosperms, ferns, 'horsetails; and 'club-mosses', and reflects the veg etation of the levee-banks within the Late Carboniferous coal-forming swamps. The assemblage belongs to the Dicksonites plueckenetii Subzone (upper Lobatopteris vestita Zone) and can be compared with coeval ass emblages from South Wales, the Forest of Dean and the Maritime Provinc es of Canada.
