Trachemys inflata

Reptilia - Testudines - Emydidae

Taxonomy
Chrysemys inflata was named by Weaver and Robertson (1967). Its type specimen is UF 12469 (holotype), a partial shell (nuchal plate), and it is a 3D body fossil. Its type locality is Palmetto Mine, which is in a Hemphillian marginal marine sandstone in the Peace River Formation of Florida.

It was considered a nomen dubium by Vlachos (2018); it was recombined as Trachemys inflata by Holman and Parmley (2005) and Weems (2023).

Diagnosis
ReferenceDiagnosis
R. E. Weems 2023Vlachos (2018) observed that this species was based originally only on a nuchal plate that was differentiated from other emydid species by the presence of a deep nuchal notch associated a significant cervical scute protrusion. He concluded that these characteristics are common among emydids, they are not diagnostic for any particular species, and therefore this species is a nomen dubium. I, however, can find no other turtle material reported from the Miocene or Pliocene of the Atlantic Coastal Plain that can be confused with this taxon, and the morphology of the posterior peripheral and costal elements reported here (Figure 1.16C–E) and in Auffenberg (2001) clearly indicates that this material pertains to a species of Trachemys and not Chrysemys.
