Also known as Marks Head Formation fauna
Where: Florida (28.9° N, 82.5° W: paleocoordinates 29.1° N, 79.6° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Marks Head Formation (Hawthorn Group), Aquitanian to Aquitanian (23.0 - 5.3 Ma)
• Data a composite of Marks Head Formation localities in Florida.
• formation-level stratigraphic resolution
Environment/lithology: marine; lithified, phosphatic, argillaceous, sandy dolomite and sandy claystone
•From another source: consists of interbedded sands, clays and dolostones throughout its extent. Carbonate beds are more common in Florda than in Georgia. Also defined as complexy interbedded shell limestone, clay, clayey sand and fine-grained sandstone. Carbonate is typically well-indurated to poorly consolidated dolostone, quartz sandy, phosphatic and clayey.
