Where: England, United Kingdom (50.9° N, 3.3° W: paleocoordinates 39.2° N, 0.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Hysteroceras varicosum ammonoid zone, Blackdown Greensand Formation, Late/Upper Albian (105.3 - 99.6 Ma)

• Horizon B - 2.26 m above the base of the section. Belongs to H. varicosum zone. (upper Albian). This is possibly equivalent top Downes (1882) Bed 7. The total section thickness was 7 m. Blackdown Greensand is an informal unit, describing a 30 m+ Cretaceous sequence of decalcified sands with layers of cherty sandstone concretions. The Greensand unconformably overlies Triassic and Jurassic strata..

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, shelly/skeletal sandstone

Size class: macrofossils

Collection methods: No repository mentioned, but presumably this is the British Geological Survey.
