AWa-1c Hatchetigbee (Eocene of the United States)

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

• Paleocoordinates: 34.8° N, 64.7° W (Wright 2013)

• 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, this is the uppermost. 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 marl

• None specific to this site, glauconitic marly sand is lithology description for the upper beds of Hatchetigbee formation in general.

Size class: mesofossils
