Also known as Hordwell

Where: England, United Kingdom (50.7° N, 1.6° W: paleocoordinates 49.2° N, 5.5° W)

• local area-level geographic resolution

When: Headon Beds Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• The Marchioness calls these units "Strata 6 and 7" and they are grouped by Cray, 1973 as the "blue and green clays"

Environment/lithology: ferruginous, sandy, calcareous claystone and green, blue, argillaceous, sandy, carbonaceous marl

Size class: macrofossils

Collection methods: In 1852, the Marchioness of Hastings published an almost identical paper to her 1853 report. I used the later English version, but the earlier paper is the more primary reference.
