Cherokee sink [Tampa Limestone] (Oligocene to of the United States)

Also known as Mansfield locality #15

Where: Wakulla County, Florida (30.2° N, 84.3° W: paleocoordinates 30.5° N, 79.4° 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

• Sand size quartz grains and an abundance of freshwater molluscs in the Tampa Limestone indicate nearshore deposition.
• The Tampa LS member of the Arcadia Fm. is more quartz sand rich and poorer in calcium carbonate than the underlying Suwannee LS. Fossils are often preserved via silicification and can be found in fully replaced, partially replaced or unaltered states. From several localities, a buff to dirty limestone matrix is reported, speckled with quartz sand grains of medium size.

Size class: mesofossils

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