FIGURE 25 in Chinlechelys from the Upper Triassic of New Mexico, USA, and the origin of turtles
FIGURE 25. Phylogeny resulting from our cladistic analysis, excluding Eunotosaurus as well as all Chinlechelys skull characters, adding in the two autapomorphies of the Pareiasauridae and testing the position of Testudines within the Reptilia. This was based on the modified version of the Szczygielski matrix presented in this paper and run through the program TNT with multistate characters ordered. Bremer support values above one are listed above nodes and bootstrap values above 50% are listed below nodes.
