Unit 4, Fruitville Mbr, Tamiami Fm (Pliocene of the United States)

Where: Florida (27.3° N, 82.4° W: paleocoordinates 27.4° N, 81.8° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Fruitville Member (Tamiami Formation), Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Fruitville Mbr of the Tamiami Fm, Okeechobee Grp, which is overlain by the Fordville Mbr of the Caloosahatchee Fm, and overlies the Golden Gate Mbr of the Tamiami Fm. Correlative with the Yorktown, Chowan RIver, Waccamaw, Jackson Bluff Fm, and the upper Golden Gate Mbr of the Tamiami Fm. THICKNESS: Varies between 5 and 8 m across areal extent. AGE: Late Pliocene. Based on macrofossil biostratigraphy the unit is throught to represent the latest Piacenzian. STRATIGRAPHIC POSITION: Checklist representative of beds representing unit 4, at the top of the member, at the top of the APAC section.

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; unlithified, shelly/skeletal, silty sandstone

• ENVIRONMENT: Lagoonal and subtidal carbonate; mangrove forests and mudflats, sand flats and turtle grass beds.
• SPECIFIC LITHOLOGY: Interbedded unit variably composed of organic rich quartz sand and muddy quartz sand with densely packed skeletal material.. LITHIFICATION: Unlithified, based on figured specimens and facies description.

Size class: macrofossils

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