Investigatio altera, ab aisdem auctoribus, Lissamphibia intra Temnospondylos posuit, Lepospondylis sic extra grege coronali Tetrapodis, Temnospondylis intra eum. <!--Another prevailing theory not represented by either of the cladograms is a [[diphyletic]] grouping of Lissamphibia with both Lepospondyli and Temnospondyli, with [[gymnophiona]]ns belonging to the former clade and [[anura]]ns and [[caudata]]ns belonging to the latter.-->}}
