Cliffend, Osborne Beds (bed 4), 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 10 ft thick.

• bed-level stratigraphic resolution

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

• This bed is reddish and bluish calcareous clays, with pale green nodular concretions containing shells, passing below into red and green mottled clay, and becoming a white marl at thebase. The Osborne Series here are clays and marls, in places concretionary and ferruginous, as well as laminated

Size class: macrofossils

Preservation: concretion
