Where: Walton County, Florida (30.6° N, 86.2° W: paleocoordinates 30.7° N, 85.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Jackson Bluff Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)
• LITHOSTRATIGRAPHY: From the Choctawhatchee, which overlies the Shoal River Fm (Middle Miocene) as originally entered; placed here in Jackson Bluff Fm. AGE: Late Miocene, on the basis of macrofossil and microfossils biostratigraphy as originally entered; placed here in Late Pliocene. STRATIGRAPHIC RELATIONS: From either the Arca or Ecphora (more likely) zones of the Choctawhatchee Fm (upper part); Smith designated these the Permenter's Farm beds, which comprise 25 ft of fossiliferous gray marl.
