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