Introduction Jefferson County during the Miocene would have a shoreline dividing the county with land occupying the northern half.Florida during the MioceneFlorida during the PleistoceneThe '''Jefferson County, Florida paleontological sites''' are assemblages of Mid-Miocene to Late Pleistocene vertebrates from Jefferson County, Florida, United States.
Age '''Era''': Neogene'''Period''': Miocene to Pleistocene, ~23.03 Mya—11,000 years ago. (calculates to a period of approximately ). '''Faunal stage''': Clarendonian through early Rancholabrean
Sites '''Ashville site''' (Miocene) Time period: ~13.5—12.7 Mya. '''Aucilla River site''' (Pleistocene) Time period: ~126,000—11,000 years ago. The Aucilla site specimens were discovered by amateur paleontologist Dr. Richard Ohmes of Bremerton, Washington in 1969.Coordinates: '''Wacissa River site''' (Pleistocene) Time period: ~126,000—11,000 years ago.
