The evolution of Trachemys, while being heavily documented with various fossil representatives, is not well understood.

A review of previously named Trachemys taxa reveals that a huge majority of them are not valid or have been previously misinterpreted. A phylogenetic analysis preformed on modern emydids and supposed fossil representatives of those genera also shows the evolution of a portion ...
