lumbar vertebrae (.313), (USNM); 1 metacarpus (.401); 1 lunar scaphoid 

 pisiform (.314); 1 neural process (USNM), 1 right hoof core (S.C. 

 92.22.1). 



Remarks: Leidy (1860) reported the first bison material from South 

 Carolina, as B. latifrons. Hay (1923) mentions a fossil which he refers 

 to as Bison sp., and Allen (1926) identified a single molar as Bison 

 sp. cf. B. bison. Allen also mentions a horn core and suggests that it 

 belongs to a bovid. The Edisto Island fossil assemblage (Roth and 

 Laerm 1980) contains bison material and is identified only as Bison 

 sp. The molars and postcranial material from the Ardis site are assigned 

 to B. antiquus based on size. These specimens are larger than modern 

 B. bison and comparable in size to B. antiquus. 



This is the first report of Bison antiquus from South Carolina. 



Order Rodentia 

 Family Sciuridae 

 Glaucomys volans - Southern Flying Squirrel 

 Material: 1 left femur (.171). 



Remarks: The specimen, a femur broken just below the distal end, is 

 assigned to G. volans based on the length of the shaft compared to 

 the width of the proximal end, and overall smaller size compared to 

 G. sabrinus. 



This species is found commonly today in the eastern United 

 States. It ranges as far north as Canada and southwest into Mexico 

 and Guatemala (Kurten and Anderson 1980). 



Typical habitats are deciduous and mixed hardwood forests. Glaucomys 

 fossils found in the southeastern United States are commonly collected 

 from cave deposits frequented by birds of prey during the time of 

 deposition (Guilday 1962; Guilday et al. 1969, 1977, 1978; Grady 

 and Garton 1982). The femur is believed either to have been "washed 

 in" or carried by a non-avian predator. There is no evidence of regurgitated 

 pellets from roosting raptors, and the entrances and the chambers of 

 the solution tunnels throughout the site were too small to facilitate 

 large roosting birds. 



This represents the first fossil evidence of a southern flying 

 squirrel in South Carolina.
