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)
• The Unio bed lies between the Rodent bed (above) and a green clay unit (below), as described by Cray, 1973. The Marchioness herself describes it as "Stratum 3"
• bed-level stratigraphic resolution
Environment/lithology: shelly/skeletal, gray, yellow claystone and lignite
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.
