Pseudemys caelata
Taxonomy
Pseudemys caelata was named by Hay (1908) [nuchal plate designated as the holotype by Hay 1908]. Its type specimen is USNM 2508, a partial shell (nuchal plate), and it is a 3D body fossil. Its type locality is Mixson's Bone Bed, which is in a Hemphillian terrestrial horizon in the Alachua Formation of Florida.
It was recombined as Chrysemys caelata by Jackson (1976); it was considered a nomen dubium by Vlachos (2018).

| R. E. Weems 2023 | Vlachos (2018) felt that the holotype nuchal described by Hay (1908) was insufficient to erect a new species of Pleistocene Pseudemys, but the Late Miocene age of this material and the fact that the material of its junior synonym Chrysemys carri includes a nearly complete carapace and plastron together provide ample evidence that this is a valid taxon. |
