Where: England, United Kingdom (50.9° N, 3.3° W: paleocoordinates 39.2° N, 2.3° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Blackdown Greensand Formation, Albian (113.0 - 100.5 Ma)
• Horizon C - 3.2 m above the base of the section. This is possibly equivalent top Downes (1882) Bed 8 or 9. 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, concretionary, shelly/skeletal, cherty/siliceous sandstone
Size class: macrofossils
Collection methods: No repository mentioned, but presumably this is the British Geological Survey.
