Also known as Mansfield Loc. #22

Where: Gadsden County, Florida (30.7° N, 84.8° W: paleocoordinates 31.0° N, 79.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tampa Limestone Member (Arcadia Formation), Chattian to Chattian (28.1 - 20.4 Ma)

• LITHOSTRATIGRAPHY: Formerly referred to as the Tampa Limestone. Scott et al. (2001) assign the Tampa to the rank of member and place it in the Arcadia Formation. AGE: Mansfield suggests age equivalencies (based primarily on faunal similarities) with the Chipola Fm., the Trent Marl of North Carolina, and the Anguilla Fm. of Anguilla. Placed here into the Chattian-Aquitanian on the basis of most recent chronostratigraphy.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, white, sandy, cherty/siliceous limestone

Size class: mesofossils

Preservation: cast, mold/impression, permineralized, replaced with silica
