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

• This bed is dark greenish gray sand and clay. This unit in general is clay with sands and marls, in places it has pebble or shell beds.

Size classes: macrofossils, mesofossils
