Where: Florida (27.2° N, 81.9° W: paleocoordinates 27.6° N, 77.9° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Arcadia Formation (Hawthorn Group), Chattian to Chattian (28.1 - 11.6 Ma)
• The Arcadia Formation is a composite sequence containing four high-frequency sequences composed of multiple vertically stacked carbonate cycles. Most cycles do not show evidence of subaerial exposure and were deposited under more temperate conditions, relative to the Suwannee Limestone. The Arcadia Formation in southernmost Florida is bounded by regional unconformities representing third-order sequence boundaries.
• formation-level stratigraphic resolution
