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
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
