Hollington Quarry (BMNH) (Cretaceous of the United Kingdom)

Also known as Little Ridge Quarry

Where: England, United Kingdom (50.9° N, 0.5° E: paleocoordinates 41.7° N, 10.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Wadhurst Clay Formation (Wealden Group), Early/Lower Valanginian (140.2 - 136.4 Ma)

• The Wadhurst Clay Formation of the Hastings Beds Subgroup has an ages of Lower Valanginian according to Radley (2006; vide Allen & Wimbledon 1991)

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithology not reported

• 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)

Size class: macrofossils
