Cliffend, Osborne Beds (bed 2), Isle of Wight (Eocene of the United Kingdom)

Where: England, United Kingdom (50.7° N, 1.5° W: paleocoordinates 49.2° N, 5.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Osborne Beds Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• It is not clear how these beds correlate with the section Forbes describes at Seafield, even the yellow limestone that marks the boundary between the "St. Helen's Sands" and the "Nettlestone Grits" is absent here. The bed is 25-30 ft thick.

• bed-level stratigraphic resolution

Environment/lithology: concretionary, ferruginous, calcareous claystone and concretionary, green, red, argillaceous marl

• This bed is a succession of various coloured marls, with nodular concretions, in which fossils occasionally occur, and bands of argillaceous limestone. The Osborne Series here are clays and marls, in places concretionary and ferruginous, as well as laminated

Size class: macrofossils

Preservation: concretion
