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: os 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 6 ft thick.

• bed-level stratigraphic resolution

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

• This bed is dark blue and brown clay alternating with concretionary ironstone bands, and bands in red and green marls. The Osborne Series here are clays and marls, in places concretionary and ferruginous, as well as laminated.

Size class: macrofossils
