Planularia kintradwellensis sp. nov. (Foraminifera), a distinctive biostratigraphical marker species for the Lower Kimmeridgian of the U.K.

Francis John Gregory

Abstract. A foraminiferal species, Planularia kintradwellensis sp. nov., previously left in open nomenclature, is shown to have a useful short stratigraphical range. It has been recovered from several onshore sites within the UK and only from the Lower Kimmeridgian.
