The Polk County paleontological sites are assemblages of Early Miocene to Late Pleistocene vertebrates occurring in Polk County, Florida, United States.

Age[edit]

Era: Neogene
Period: Miocene to Pleistocene, ~17.7—1.5 Mya. (calculates to a period of approximately 16.2 million years).
Faunal stage: Hemingfordian through early Clarendonian
Geological Formation: Bone Valley Formation.

Sites[edit]

Polk County can boast more individual fossil recovery sites than any other Florida county due to the phosphate mining concerns. Bone Valley Formation is a prime geologic formation. Some of these sites are: Agricola Road (AEO),[1] Agrico Pierce Mine (AEO), American Agricultural Chemical Company Mine, Brewster Phosphate Mine, Fort Meade Mine,[2] Kingsford Mine, Phosphoria Mine, Fort Green Mine, Payne Creek Mine, and Palmetto Mine.
