ammonites
Choctawhatchee Formation (unspecified localities) (Miocene of the United States)

Where: Florida (30.5° N, 84.2° W: paleocoordinates 30.7° N, 82.5° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Choctawhatchee Formation (Alum Bluff Group), Late/Upper Miocene (11.6 - 5.3 Ma)

• LITHOSTRATIGRAPHIC RELATIONS: From the Choctawhatchee Fm of the Alum Bluff Gp; alternatively the Red Bay Fm of the Chochtawhatchee Fm. AGE: Late Miocene age based on recent lithostratigraphy. STRATIGRAPHIC POSITION: From the Arca zone within the Choctawhatchee Fm.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified sandstone

• No reported geologic or paleoenvironmental data. Probably shallow water siliciclastic depositional environment.
• LITHOLOGY: Unknown, but assumed to be similar to other parts of the Choctawhatchee Fm. LITHIFICATION: Unlithified, as for other collections from the Choctawhatchee Fm.

Size class: macrofossils

Collection methods: COLLECTOR: Unknown, possibly Sellards or Mansfield. REPOSITORY: Unknown, possibly USNM or Florida Geological Survey.
