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
Size class: macrofossils
Preservation: concretion
