Where: Hillsborough County, Florida (27.9° N, 82.5° W)

• Paleocoordinates: 30.6° N, 72.8° W (Wright 2013)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Tampa Limestone Member (Arcadia Formation), Chattian to Chattian (27.3 - 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 classes: macrofossils, mesofossils

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

Collection methods: Collections made from Ballast Point are noted to be, at least in part, the product of channel dredging activities and come from the the point and the local vicinity. Presumably (although not directly noted) this resulted in float collection.
