Clemmys is a genus of turtles currently containing a single extant species, the spotted turtle (Clemmys guttata).

Taxonomy

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.[3]

Extant species formerly in Clemmys

Wood turtle - now Glyptemys insculpta
Bog turtle - now Glyptemys muhlenbergii
Western pond turtle - now Actinemys marmorata

Fossil species

†Clemmys hesperia Hay, 1903 - Pliocene
†Clemmys owyheensis Brattstrom & Sturn, 1959 - Miocene (Hemphillian)
