Vertebrate correlations and Miocene stratigraphy of north Florida fossil localities

Five previously recorded and three newly reported Miocene vertebrate localities in northern Florida are discussed in relation to shoreline positions of Miocene seas previously established by lithologic and invertebrate fossil evidence. Remains of the anchitherine horse Parahippus, restricted to the Miocene in North America, are found in all eight localities and can be used as an ecologic indicator as well as for dating the beds; teeth from the new localities, Chattahoochee, Alum Bluff, and Colclough Hill, are illustrated. Deposits at the Thomas Farm and Newberry localities indicate terrestrial conditions; those of the other six localities contain a mixture of terrestrial and lagoonal vertebrates. Vertebrate evidence supports the lithologic and invertebrate evidence.
