Where: Monroe County, Alabama (31.8° N, 87.4° W: paleocoordinates 34.3° N, 70.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Bells Landing Marl Member (Tuscahoma Formation), Thanetian (59.2 - 56.0 Ma)

• replicates are all from 7 ft above water level, about 1m apart.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; unlithified, glauconitic, muddy sandstone

Collection methods: bulk, sieve,

• Gastropod shells were only counted if they contained the apex of the shell; bivalves shells were only counted if they contained the umbo.
