Lee-on-the-Solent, Elmore Formation (Eocene of the United Kingdom)

Where: England, United Kingdom (50.8° N, 1.2° W: paleocoordinates 47.6° N, 4.6° W)

• coordinate stated in text

• local area-level geographic resolution

When: Elmore Formation (Bracklesham Group), Lutetian (47.8 - 41.3 Ma)

• authors are erecting this as a new formation, within the Huntingbridge division, Bracklesham Group. They equate it with the Selsley division, so I'm calling it Lutetian. The sequence is 9.05 m thick and is overlain by Pleistocene and Recent deposits.

• formation-level stratigraphic resolution

Environment/lithology: marginal marine; sandy claystone and argillaceous, silty sandstone

• sandy clays with thinner beds of silty sand and silty clays

Size classes: macrofossils, mesofossils

Preservation: concretion

Reposited in the BMNH

• and Gosport Museum
