Stratigraphy
Geological group:Wealden Formation:Wadhurst Clay
Stratigraphic resolution:bed
Stratigraphy comments: The Wadhurst Clay Formation of the Hastings Beds Subgroup has an ages of Lower Valanginian according to Radley (2006; vide Allen & Wimbledon 1991)
Lithology and environment
Primary lithology: claystone
Includes fossils?Y
Environment:lacustrine - small
Geology comments: Shallow, freshwater to slightly brackish lakes, including horsetail ‘reed’ bed and terrestrial fauna. Fossils throughout the Wadhurst Clay Formation include ostracods, conchostracans (‘clam-shrimps’), pond-snails and the low-salinity bivalve Neomiodon. Widespread siltstone and fine sandstone gutter- and scour-fills indicate storm activity and/or fluvial runoff into the Wadhurst lakes (Radley 2006)
