Regional distribution of Pleistocene Actinemys pallida

Actinemys pallida (Seeliger 1945)—Southern Western Pond Turtle

Until recently, Actinemys marmorata was considered to consist of a single species; two species are now recognized (Spinks et al. 2014): A. marmorata to the north and A. pallida to the south. Fossils noted here fall into the current range of A. pallida and are recognized here as that species solely on the basis of the current geographic distribution.

The Western Pond Turtle is an aquatic species of the west coast of temperate North America west of the crests of the Cascade and Sierra Nevada ranges.

Synonyms. Actinemys marmorata, Clemmys marmorata.
