Article: Marine-brackish bands and their microfauna from the lower part of the Weald Clay of Sussex and Surrey

A brackish-marine microfauna is described from the lower part of the Weald Clay (Cypridea tubercu-lata Zone) of Sussex. The fauna is dominated by ostracods; eight species are described, one subgenus and three species are new. One species of arenaceous foraminifera, and cirripedes, have also been found. The salinity range of the various species is critically examined and the fauna is compared with other Lower Cretaceous microfaunas outside the Weald.
