Pleistocene Mammals Central Florida 77 



tympanic (UF 48984); vertebrae material (UF 48979-48980, V-4469); 

 ribs (UF 48977-48978, V-4380). 



Remarks. — Various states of preservation are evident in this mana- 

 tee material. Some is well permineralized, whereas other specimens are 

 only slightly fossilized. The material was probably deposited during sev- 

 eral different intervals, including times when the site was marine or 

 estuarine, or when it comprised a freshwater system occupied by mana- 

 tees much as are many other river systems in Florida today. 



Order Perissodactyla 



Family Tapiridae 



Tapirus veroensis Sellards 1918 



Material— Palate with left U, 13, PJ_, M3 and right PJ_-M3 (UF 

 18702); left maxilla with MNM3 (V-4389);_upper molar fragment (UF 

 48970); left dentary and_symphysis with P4-M3 (V-4390/4391); partial 

 right dentary with_P4-M3 (UF 12485); left 12 (UF 48971); deciduous P2 

 (UF 8945); left P2 (V-4396); lower molar (UF 48969); 5 isolated teeth 

 (V-4454). 



Remarks. — All referred material resembles T. veroensis rather 

 than the larger T. copei Simpson 1945. 



Family Equidae 



Equus sp. 



Material— Upper cheektooth (UF 48975); lower molar (UF 48974); 

 incisors (UF 48972-48973); radius (V-4471). 



Remarks. — The material represents several states of preservation. 

 The unfossilized radius, that of an immature individual, probably 

 represents the domestic Equus caballus. The dental material is fossilized 

 and is provisionally referred to Equus sp. 



Order Artiodactyla 



Family Tayassuidae 



Mylohyus nasutus (Leidy) 1869 



Material— Partial right mandible with P3-M3(UF 17720). 



Remarks. — This specimen is particularly interesting because of its 

 preservation. Overall coloration of the specimen is black, in contrast to 

 buff or chalky colors of most other Rock Springs material. The ventral 

 surface of the dentary is broken away to expose the mandibular canal. 

 External surfaces of the jaw, as well as the internal surfaces of the man- 

 dibular canal, are encrusted with growths of various marine organisms, 

 including barnacles. Assuming in situ deposition, this specimen further
