Bootstrap tree obtained from the published matrix used by Pardo et al. (2017a) when all characters are unordered (analysis b). The bootstrap tree shows moderate support (52%) for the diphyly of extant amphibians. Colors and boldface as in Fig. 3, bootstrap values ≥ 50% also in boldface; darker brown rectangle for Lapillopsis, a small temnospondyl thought to be a stereospondyl convergent to dissorophoids. The blue rectangle for Temnospondyli is omitted because all OTUs except Greererpeton and Proterogyrinus are (inferred to be) temnospondyls; the cyan rectangle for Lissamphibia is omitted because the name Lissamphibia does not apply on this tree. Tr.-oidea = Trematosauroidea. The Dendrerpetidae OTU was called “Dendrerpeton acadianum” by Pardo et al. (2017a) but is mostly based on its apparently close relative Dendrysekos. In this and the following figures we have also corrected spelling mistakes in taxon names compared to the matrix and the figures of Pardo et al. (2017a).
