Pliensbachian and Toarcian ostracods are described from an interbedded marlstone/carbonate-mud •sequence in South-West England. Sediments of this age in other parts of Britain rarely offer a lithology favourable to the examination of calcareous microfossils. The fauna possesses similarities with other European sequences, particularly to the south. The presence of one species, Ektyphocythere dharennsourensis Boutakiout, Donze & Oulmalch, 1982 suggests possible links with North-West Africa at this time.
