Where: Florida (25.9° N, 81.3° W: paleocoordinates 26.0° N, 80.5° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Sarasota Member (Murdock Station Formation), Early/Lower Pliocene (5.3 - 3.6 Ma)
• STRATIGRAPHIC RELATIONS: From the Sarasota Mbr of the Murdock Station Fm, Hawthorn Grp, which is overlies the Jupiter Waterway Mbr of the Murdock Station Fm and is overlain by the Tamiami or Fort Thompson Fms.
