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 part of 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. When adding the occurrences from Gardner et al., this is a best-guess (based on fossil occur.) in correlating this bed with their Lower Barton fossils.
• bed-level stratigraphic resolution
Environment/lithology: marine; pebbly, shelly/skeletal, sandy, calcareous claystone and concretionary, green, calcareous sandstone
Size class: macrofossils
