Mollusca of the "Glades" Unit of Southern Florida: Part I Introduction and Observations

Abstract

In southern Florida there is a shell deposit lying above the Caloosahatchee Marl of late Tertiary age and below the Pleistocene Fort Thompson Formation. This paleontologically distinctive unit was temporarily designated as "Unit A" by Olsson (in Olsson and Petit, 1964, Bulls. Amer. Paleontology, v. 47, no. 217, p. 513, 521), pending its formal naming by Druid Wilson of the U. S. Geological Survey. To date this name has not been published and until it is formally proposed we must refer to it by some sobriquet. Appropriately, most local workers have been terming it the "Glades" for some time, so this name will continue to serve. To date, the deposit has been identified from the following south Florida counties: Glades, Indian River, St. Lucie, Martin, Palm Beach, Broward, and Hendry.
