76 Kenneth T. Wilkins 



Ursus americanus 



Material— Two upper M3's (UF 8951-8952); femur (UF 8953). 



Remarks. — The black bear presently occurs throughout much of 

 Florida. An unfossilized femur attests to its relatively recent occurrence 

 in the Rock Springs vicinity. Generic identity of other ursid material is 

 uncertain: distal humerus (UF 49203); canine fragment (UF 49204). 



Family Felidae 



Felis amnicola Gillette 1976 



Material— Right dentary with P3-MT (UF 4522) 



Remarks. — This specimen was originally recognized and illustrated 

 by Ray (1964) as a jaguarundi, Felis yagouaroundi. Subsequently, 

 Gillette (1976) described a new species of small river cat, F. amnicola, to 

 which he referred this Rock Springs dentary. 



cf. Felidae 



gen. et sp. indet. 



Material— Phalanx (UF 8954) 



Remarks. — Webb's (1974) tabulation of "Felis sp." at Rock Springs 

 probably refers to this specimen, which compares favorably in size with 

 the modern Florida panther, Felis concolor coryi Bangs 1899. 



Order Proboscidea 



Family Mammutidae 



Mammut americanum (Kerr) 1791 



Material. — Right dentary fragment (V-4378); molar fragments (UF 

 48986, V-4385, V-4464); molar enamel fragment (V-4465). 



Family Elephantidae 

 Mammuthus sp. (Falconer) 1857 



Material— Molar (V-4473); molar plates (UF 48987, V-4383); tusk 

 fragments (V-4384). 



Remarks. — In accordance with Kurte'n and Anderson (1980), 

 mammoth material is provisionally referred to Mammuthus sp. pending 

 comprehensive study of the genus.

Material— Cheektooth (UF 48981); cheektooth fragment (UF 

 48982); edentulous maxillary fragment (V-4451); ear ossicle (UF 48983);
