Hempstead Cliff, Bembridge Marls (bed 1), Isle of Wight (Eocene of the United Kingdom)

Where: England, United Kingdom (50.7° N, 1.5° W: paleocoordinates 49.2° N, 5.3° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Bembridge Marls Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• Forbes doesn't give a thickness of these beds. He uses a different numbering system with the units at this locality than ones he uses at other localities (numbers vs. letters), for this locality he doesn't even give bed thicknesses, making them difficult to correlate. He does begin the sequence at this locality with the "Black Band" with which he ended the series of Hempstead series. This bed is right below it.

• bed-level stratigraphic resolution

Environment/lithology: concretionary marl and bioturbated, shelly/skeletal, green marl

• This unit is green marl, with scattered individual shells and a seam of crushed shells and vertical root-like bodies. The Bembridge Marls at this locality are concretionary marls and clays.

Size class: macrofossils
