14 C. C. Bentley, J. L. Knight, and M. A. Knoll 



1980), based on mandibular fragments and postcranial remains. The 

 material from the Ardis local fauna represents the second report of 

 fossil P. lotor from South Carolina. 



Family Ursidae 

 Tremarctos floridanus - Florida Cave Bear 

 Material: 1 right m3 (.264); 1 first right metatarsal (.265) 



Remarks: The m3 of Tremarctos floridanus differs from Ursus americanus 

 in that it lacks the double root, and is substantially smaller than any 

 other ursid in the eastern United States. The Florida cave bear has 

 been recovered from Rancholabrean sites in Florida, Georgia, Tennessee, 

 Kentucky, New Mexico, Texas, and northern Mexico (Kurten and 

 Anderson 1980). Based on the fossil record it would appear that the 

 Florida cave bear had a more southeastern distribution during the late 

 Pleistocene. The material from the Ardis local fauna represents the 

 second report of this species (Roth and Laerm 1980), from South 

 Carolina. Both reports are from deposits along the Coastal Plain of 

 the State. 



Order Proboscidea 

 Family Mammutidae 

 Mammut americanum - American Mastodon 

 Material: 1 partial milk tooth (.332); 2 partial molars (.333, .334). 



Remarks: The American mastodon was first reported in the fossil 

 record for South Carolina from Edisto Island by Roth and Laerm 

 (1980). 



Family Elephantidae 

 Mammuthus columbi - Columbian Mammoth 

 Material: 1 complete molar (.335); partial molar (.336); partial scapula 

 (in the collections of Lander University). 



Remarks: All identifiable Mammuthus remains from the area of the 

 Ardis local fauna have been recovered from the quartz sand layer 

 above the Harleyville clay, and not in direct association with the 

 Ardis fauna proper. Identification is based on the lamellar frequency 

 (7) of the occlusal surface coupled with the late Pleistocene date of 

 the site (Kurten and Anderson 1980). Carbon dating of the bone from 

 a scapula associated with a complete and a partial molar of M. columbi 

 gave a date of 18,530 ± 725 y.p.b., within the range of the Ardis 

 local fauna and here considered contemporaneous with it.
