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. Fossil species are now restricted to the Neogene of North America as far back as the Miocene.

'*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)
