Hordle Cliff shell bed (within Mammal Bed), Hampshire (Eocene of the United Kingdom)

Also known as Hordwell

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

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• this horizon occurs immediately above the ironstone band (number 8 in Tawney and Keeping, 1883) which is usually considered to mark the base of the Mammal Bed. Age is Upper Eocene (Lower Ludian).

• bed-level stratigraphic resolution

Environment/lithology: shelly/skeletal packstone and concretionary, ferruginous, sandy, calcareous claystone

• the Headon Beds are predominantly clays, with varying amounts of sand, limestone and ironstone

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.
