Where: Florida (27.2° N, 81.8° W: paleocoordinates 27.4° N, 80.2° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Peace River Formation (Hawthorn Group), Tortonian to Tortonian (11.6 - 3.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Peace River Fm, Hawthorn Grp, which is overlain by the Bayshore Fm. Correlative with the St Marys and Shoal River Fms. THICKNESS: Varies between 100 and 200 m across areal extent. AGE: late Midde-early Late Miocene. Based on macrofossil biostratigraphy the unit is throught to represent the Serravallian-early Tortonian; here assigned to Serravalian. STRATIGRAPHIC POSITION: Checklist representative of entire member.

•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: lagoonal or restricted shallow subtidal; lithified, medium, dolomitic, phosphatic, argillaceous sandstone

Size class: macrofossils

Preservation: cast, mold/impression

Collection methods: COLLECTOR: Unknown, presumably the authors and others. REPOSITORY: No repository stated.
