Where: Florida (26.9° N, 82.1° W: paleocoordinates 27.1° N, 80.5° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Peace River Formation (Hawthorn Group), Tortonian to Tortonian (11.6 - 3.6 Ma)
• Data a composite of Peace River Formation localities in Florida
•Previously Barstovian, but Missimer (1999) suggested that the Peace River Formation in Florida was likely deposited between 11-4.3Ma. The lower sequence is Tortonian, deposited between 11-8.5Ma, and the upper sequence is Zanclean and deposited between 5.2-4.3Ma
• formation-level stratigraphic resolution
Environment/lithology: marine; poorly lithified, fine, medium, dolomitic, phosphatic, gray, argillaceous sandstone and lithified, dolomitic, phosphatic, gray, yellow, silty, sandy claystone
