Georgia Journal of Science
The early Pleistocene (ca. 2.588–1.806 Ma) Santa Fe River 1B fossil site (SF1B) of Gilchrist County, Florida has yielded turtle fossils representing nine genera and at least 10 species. Of these, at least six genera are aquatic turtles (Macrochelys and/or Chelydra, Apalone, Trachemys, Pseudemys, Sternotherus, and Kinosternon) and three are terrestrial (Hesperotestudo, Gopherus, and Terrapene). Hesperotestudo and an undescribed cf. Trachemys are the only extinct turtles identified in the paleoherpetofauna. Overall, the generic composition of the turtle fauna is predominantly modern and indicative of the southeastern United States today.
