Where: Washington County, Alabama (31.1° N, 88.0° W: paleocoordinates 33.1° N, 73.7° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: upper Hatchetigbee Bluff Member (Hatchetigbee Bluff Formation), Ypresian (56.0 - 47.8 Ma)

• Four fossiliferous beds are exposed. The lower three are characterized by abundant shells of Venericardia hatcheplata, most of which consist of both valves oriented in living position. These lower beds contain a few shells of other mollusks. The uppermost fossil bed is characterized by single valves of Venericardia turneri and a large number of well preserved shells of other mollusks.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; unlithified, fine-grained, glauconitic, sandy marl

Size class: mesofossils
