Edisto Island Fossil Vertebrates 
25 
Seminole Field (Simpson 1929b) share 19 mammalian genera; Edisto 
Island and Melbourne (Ray 1958) share 20. Of the 14 vertebrate species 
recovered from the Georgia estuaries (Frey et al. 1975), 9 appear at 
Edisto Island. Although the Edisto Island fauna is in some repects similar 
to the Ladds Quarry fauna (Ray 1967), Edisto Island lacks the species 
associated with a colder climate and upland terrain (e.g., Maries pen- 
nanti, Sylvilagus transitionalis, and large sciurids). However, Edisto 
Island has several savannah dwelling species (e.g., Palaeolama, 
Glyptotherium) that are not present at Ladds Quarry, in addition to the 
marine taxa. 
The Edisto Island records of Glyptotherium, Palaeolama, and 
Geochelone constitute northern range extensions for these genera in 
eastern North America. In fact, the Charleston region of South Carolina 
represents the approximate northern limit of the range of other Late 
Pleistocene taxa including Tapirus, Mylohyus, and Neochoerus. 
The taxa occurring at Edisto Island in the Late Pleistocene represent 
essentially a coastal plain assemblage similar to late Pleistocene faunas 
found throughout Florida and the Gulf coastal region at least as far west 
as Texas (Lundelius 1972).
