Also known as (H-79-11)

Where: Hinds County, Mississippi (32.3° N, 90.2° W: paleocoordinates 33.2° N, 80.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Yazoo Clay Formation, Lutetian to Lutetian (47.8 - 33.9 Ma)

• "Late Lutetian - early Priabonian." (T. Hansen, pers. comm.)

• bed-level stratigraphic resolution

Environment/lithology: offshore; unlithified, burrowed, silty, calcareous shale

• "very poor preservation, shells were identified and counted by sorting through the sediment by hand. too fragile to be sieved."
