Also known as Mansfield station #8
Where: Marion County, Florida (29.3° N, 82.2° W: paleocoordinates 29.5° N, 77.3° 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.
• member-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, white, sandy, cherty/siliceous limestone
Size class: mesofossils
Preservation: cast, mold/impression, permineralized, replaced with silica
