Where: England, United Kingdom (50.7° N, 1.1° W: paleocoordinates 49.2° N, 5.0° W)
• coordinate estimated from map
• local area-level geographic resolution

• Forbes calls this bed 11, and calls the subunit the Nettlestone Grits (numbering starts with the St. Helen's Sands above them), a naming that I'm not sure anyone else follows. Bed thickness is 8 ft.
• bed-level stratigraphic resolution
Environment/lithology: concretionary, argillaceous, calcareous sandstone and concretionary, shelly/skeletal, cherty/siliceous limestone
Size class: macrofossils
Preservation: cast, mold/impression
