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[1] as well as some cladistic analyses.

[2] However, it was strongly contradicted by molecular evidence which supports Archelosauria (the grouping of turtles and archosaurs),[3] and other recent cladistic analyses have supported Archelosauria over Ankylopoda.

[4] The cladogram below follows the most likely result found by another analysis of turtle relationships, this one using only fossil evidence, published by Rainer Schoch and Hans-Dieter Sues in 2015.

This study found Eunotosaurus to be an actual early stem-turtle, though other versions of the analysis found weak support for it as a parareptile.
