Where: England, United Kingdom (50.7° N, 1.1° W: paleocoordinates 48.5° N, 5.0° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Barton Beds Formation, Bartonian (41.3 - 38.0 Ma)
• This bed is one of the thickest in the "London Clay" sequence recognized by Prestwich and Bowerbank. I'm using Prestwich's numbering system for the unit (Bowerbank numbers it 12). I have correlated it with Bosma's naming system as the Barton Beds.
• bed-level stratigraphic resolution
Environment/lithology: marine; pebbly, shelly/skeletal, sandy, calcareous claystone and brown, gray, sandy, calcareous claystone
Size classes: macrofossils, mesofossils
