Lithology description: Insects are abundant and can be found in sideritic and rarely, phosphatic mudstone and siltstone lenses. Unfortunately, most specimens were recovered from lenses that were not in situ. A few came from in situ lenses which can be seen projecting from the weathered south-west face. The lowest horizon is generally barren. Some of the loose insect-bearing lenses probably came from other horizons between the ripple-bedded micaceous sandstone and BGS Bed 3a. A few insects, consisting of beetle wing cases and cockroach forewings. have been found in the clay above the ripple-bedded sandstone
Environment:pond Tectonic setting:passive margin
Geology comments: The Weald Clay was deposited in a non-marinelacustrine/lagoonal/mudplain environment in the subsiding Wealden basin (Allen, 1981, 1990). The Keymer sediments illustrate a change in depositional environment from over-bank to generally low-energy fluvio Iacustrine conditions.
