Hordle Cliff, Stratum 16, Hampshire (Eocene of the United Kingdom)

Also known as Hordwell

Where: England, United Kingdom (50.7° N, 1.6° W: paleocoordinates 47.5° N, 5.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Eocene (56.0 - 33.9 Ma)

• The Marchioness calls this Stratum 16, but she's including everying in the sequence. Based on a comparison of her and Cray, 1974, it is unclear whether this is part of the Headon Beds (and part of the Mammal Bed) or the Barton Beds.

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; gray, green claystone and lignite

• the top has a band of lignite which is succeeded by a stratum of very dark mottled green and gray clay, then there is another narrow band of lignite and under that the same clay as above.

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
