Mammals of the Ardis Local Fauna 15 



All other Mammuthus material reported previously from South 

 Carolina has been assigned to M. columbi as well (Hay 1923, Allen 

 1926, Roth and Laerm 1980). 



Order Proboscidea 

 gen. et spec, indet. 



Material: 1 distal fragment of tibia (.337); 1 vertebra (.340); 1 proximal 

 rib end (.338); 6 fragments of ivory (.339a-c), (3 USNM). 



Remarks: Identification to a particular family is not possible because 

 of the fragmentary nature of these remains. Because the openings of 

 the solution cavities to the surface were small, and large mammals 

 are only represented by isolated fragments, these animals probably 

 died on the surface nearby and were washed in by periodic flooding. 



Order Perissodactyla 



Family Equidae 



Equus cf E. complicatus - Complex-toothed Horse 



Material: 2 partial incisors (2 USNM); 1 left Ml or M2 (1 USNM); 

 1 left DP3 or DP4 (.320); 1 right P3 or P4 (.319); 2 right M3s 

 (1 USNM), (1 UF); 1 left m3 (1 USNM); 1 canine (.322); associated- 

 1 axis, 3 caudal vertebrae, 1 incisor, and 3 rib fragments (.321a-h); 1 

 left distal radial end (.323); 1 right fourth metatarsal (.324); 1 left 

 second metacarpal (.331); 2 left cuneiforms (.325, .326); 1 right magnum 

 (.327); 1 right lunar (.328); 2 medial phalanx (.329, .330). 



Remarks: The Equus cheek teeth from the Ardis local fauna have 

 been tentatively assigned to the species E. complicatus based on the 

 extremely complex nature of the occlusal surface. All other remains, 

 because of the ambiguity in postcranial elements between E. complicatus, 

 E. fraternus, and E. occidentalism are referred to only as Equus sp. 



Fossil remains assigned to the genus Equus were reported from 

 South Carolina by Hay (1923), Allen (1926), and Roth and Laerm 

 (1980). 



Family Tapiridae 

 Tapirus veroensis - Vero Tapir 



Material: 1 partial right m3 (1 USNM); 1 partial m2 (UF); 2 partial 

 left m3 (.316, .317); 1 partial right molar (.318).
