Unspecified localities [Tampa Limestone] (Oligocene to of the United States)

Where: Florida (27.9° N, 82.5° W: paleocoordinates 28.1° N, 77.7° W)

• coordinate based on nearby landmark

• local area-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, quartzose, brown, sandy limestone

• Sand size quartz grains and an abundance of freshwater molluscs in the Tampa Limestone indicate nearshore deposition.
• Buff to dirty limestone matrix is reported, speckled with quartz sand grains of medium size.

Size classes: macrofossils, mesofossils

Preservation: cast, mold/impression, replaced with silica
