Map of localities in Tennessee.
Drawn after Hackley et al, 2006.
The paleoenvironment, reconstructed from the micro and megaflora and depositional profiles, was warm temperate to cool subtropical. These sediments have been dated by stratigraphic and palynological means as Paleocene/Lower Eocene (Wilcox)- Middle Eocene (Claiborne) in age (~65-41 MYBP)
