The classical phylogeny of living reptiles pairs crocodilians with birds, tuataras with squamates, and places turtles at the base of the tree. New evidence from two nuclear genes, and analyses of mitochondrial DNA and 22 additional nuclear genes, join crocodilians with turtles and place squamates at the base of the tree. Morphological and paleontological evidence for this molecular phylogeny is unclear. Molecular time estimates support a Triassic origin for the major groups of living reptiles.
现存爬行动物的经典系统发育关系将鳄鱼与鸟类归为一类，喙头蜥与有鳞目归为一类，并将龟鳖目置于进化树基部。来自两个核基因的新证据，以及对线粒体DNA和另外22个核基因的分析，将鳄鱼与龟鳖目归为一类，并将有鳞目置于进化树基部。这种分子系统发育的形态学和古生物学证据并不明确。分子时间估计支持现存主要爬行动物类群起源于三叠纪。
