Where: England, United Kingdom (51.7° N, 1.2° W: paleocoordinates 42.5° N, 8.6° E)
• coordinate estimated from map
• outcrop-level geographic resolution

• "Here only about 100 feet thick. At its base are scattered a few Coprolites; a few feet upward we find Thracia depressa, Gryphsea virgula; still higher, two 'flats' of Ostrea deltoidea; and at a height of fifteen feet a limestone-band, partly septariate, yielding Rhynchonella inconstans, and occasionally Pleiosaurian, Ichthyosaurian, and Steneosaurian bones, which also occur below it."
• group of beds-level stratigraphic resolution
Environment/lithology: marine; unlithified, fine-grained, glauconitic, green claystone
