Turtle classification

Turtles have been classified in different ways by different authors. While they were previously considered anapsids, they are now considered more derived. Recent analyses of molecular evidence have strongly suggested that they belong in the clade Archosauromorpha (also known as Archelosauria). Below are many of the possible classifications of Testudines and Testudinata:
