See text Clemmys is a genus of turtles currently containing a single extant species, the spotted turtle (Clemmys guttata).
In the past, several other species were included in the genus, including a number of fossil species.
DNA analysis has restricted the genus to containing only the spotted turtle.
[1][2] Fossil species are now restricted to the Neogene of North America as far back as the Miocene.
