Deirochelys reticularia - Chicken Turtle (Agassiz, 1857) 



Material: 2 peripherals (.542-.543). 



Characters used for identification: Identification is based upon the distinctive 

 "spike-like" pattern of the dorsal sculpturing on these elements (Jackson 1964, 

 Holman 1978). 



Remarks: This turtle today has a continuous range from Texas and Oklahoma 

 through the Gulf states and along the southern half of the Atlantic Coastal Plain 

 states into North Carolina, with isolated populations in southeastern Virginia 

 (Conant and Collins 1991). Still-water habitats, such as ponds, swamps, marsh- 

 es, and temporary pools, are commonly occupied by chicken turtles, which 

 reportedly do not favor moving water (Ernst and Barbour 1989). 



This is the first fossil record of Deirochelys from South Carolina. The 

 species most extensive fossil record and probable origin is in Florida (Jackson 1978).
