Lithology and environment
| Primary lithology: | not reported |
| 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) | |
