Extant subclades

Ankylopoda was a proposed clade that hypothetically contains turtles and lepidosaurs (tuatara, lizards and snakes) and their fossil relatives. This clade was historically supported based on microRNA analysis as well as some morphological cladistic analyses. However, it was strongly contradicted by molecular evidence which supports Archelosauria (the grouping of turtles and archosaurs), as well as some morphological analyses.
