| Stratigraphy comments: Bradley Fauna; lower beds
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 | |||||
