Abstract:The stratigraphy of the Weald Clay of Sussex in the region of Burgess Hill is summarized. The Hauterivian/Barremian boundary, using ostracod evidence in the Ripe borehole, appears to lie at the top of a red clay bed just below BGS Bed 3c2. Detailed sections of the sediments exposed in Keymer Tileworks clay pit are given. BGS Bed 3a is exposed at the top of the pit, indicating that the sediments below belong to the Lower Weald Clay and are late Hauterivian in age. The pit has yielded a diverse non-marine fossil fauna and flora consisting of insects, dinosaurs, crocodiles, turtles, sharks, bony fish, crustaceans, molluscs, ferns, conifers and a new herbaceous, aquatic or marsh-dwelling plant. The insects include the first Wealden records of the family Sciaridae (fungus gnats) and of the superfamily Coccoidea (scale insects). The sediments exposed and their fossil content indicate changes from terrestrial conditions through fluvial, culminating in a lacustrine environment.
