<li>{{Note_label|A|a|none}} Studies using [[molecular phylogenetics]], which examine the genes and proteins of living organisms, suggest that testudines (turtles) are diapsids. These studies show that mesosaurs do not form a clade with turtles that excludes diapsids, but fossil evidence still suggests that mesosaurs form a group with parareptiles. In most recent studies, Reptilia is not used as a crown group and still contains mesosaurs and Parareptilia.
