Swift Mine (Neogene of the United States)

Where: Polk County, Florida (27.9° N, 81.8° W: paleocoordinates 28.1° N, 80.1° W)

• coordinate based on political unit

When: Bone Valley Member (Peace River Formation), Late/Upper Hemphillian (10.3 - 4.9 Ma)

• Latest Hemphillian, Palmetto Fauna; Morgan (1994) lists the age as latest Hemphillian (Zanclean, early Pliocene); upper beds

•JA: changed to Zanclean by Pyenson (?), but the primary temporal information is the "Hemphillian" age assignment and the AEO data are inconsistent with a Pliocene age

Environment/lithology: terrestrial; carbonate

Size class: macrofossils
