Where: England, United Kingdom (50.7° N, 1.1° W: paleocoordinates 49.2° N, 5.0° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Upper Member (Barton Beds Formation), Late/Upper Eocene (37.2 - 33.9 Ma)
• I was unable to correlate this unit, which Gardner et al. call the Chama-bed with Prestwich either on the basis of fossils or lithology, it might correlate with bed 16 or 17, but I couldn't be sure.
• bed-level stratigraphic resolution
Environment/lithology: marine; yellow sandstone and blue, sandy claystone
Size class: macrofossils
