ammonites
Little Stave Creek 3 (Gosport Sand, AL) (Eocene of the United States)

Where: Clarke County, Alabama (31.5° N, 87.9° W: paleocoordinates 32.1° N, 79.3° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Gosport Sand Formation (Claiborne Group), Bartonian (40.4 - 37.2 Ma)

• "At each site, the horizon sampled was in the lower third of the exposure, approx. 2m above the base of the formation, but stratigraphic equivalence is undetermined."

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, glauconitic, shelly/skeletal, calcareous sandstone and shale

• the gosport sand is a deposit of early late eocene (bartonian) age, and consists of 2-10m of extremely fossiliferous, unconsolidated, glauconitic, calcareous quartz sand, with occasional indurated ledges and thin lenses of carbonaceous shale and lignite.

Size class: mesofossils

Collection methods: bulk, mechanical, sieve,

• "Numbers of specimens reflect number of identifiable gastropod apices and total number of bivalve umbos; unidentifiable fragments were not counted."
