Hordle Cliff, Stratum 17, Hampshire (Eocene of the United Kingdom)

Also known as Hordwell

Where: England, United Kingdom (50.7° N, 1.6° W: paleocoordinates 48.5° N, 5.5° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Barton Beds Formation, Bartonian (41.3 - 38.0 Ma)

• The Marchioness calls this Stratum 17 (numbered top to bottom), but she's including everying in the sequence. Based on a comparison with Bosma, 1974 Cray, 1973, it seems likely that this is part of the Barton Beds. This unit is about 20 ft in thickness

• bed-level stratigraphic resolution

Environment/lithology: ferruginous, shelly/skeletal, gray, yellow sandstone

• this bed consists entirely of sand that is variable in color, from gray to light yellow, some iron bands are seen within it, and these contain shells

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
