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 Marchioness calls this unit "Stratum 8". Cray, 1973 locates this unit between the blue and green clays and the Ironstone Bed. Age is Upper Eocene (Lower Ludian). Thickness of this bed is approx 3-10 inches.

• bed-level stratigraphic resolution

Environment/lithology: ferruginous, sandy, calcareous claystone and packstone

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.

Primary reference: M. Hastings. 1853. On the Tertiary Beds of Hordwell, Hampshire. Philosophical Magazine and Journal of Science, Fourth Series 6(36):1-11 [J. Alroy/E. Leckey/E. Leckey]more details

Purpose of describing collection: taxonomic analysis
