Inclusive 33-taxon, 108-character dissorophoid analysis; recovered lissamphibians within Amphibamiformes while documenting polytomies, homoplasy and alternative origin scenarios.
A 33-taxon, 108-character dissorophoid analysis recovered sampled lissamphibians within Amphibamiformes near Gerobatrachus, supporting a monophyletic temnospondyl-origin hypothesis while retaining polytomies, homoplasy and unresolved support.
claim:taxon:lissamphibia:temnospondyl-hypothesisAfter documenting 4,200 corrected matrix cells and adding 56 terminal taxa, one expanded morphology analysis recovered a lepospondyl-origin tree as 9–10 steps shorter than constrained temnospondyl alternatives, while reporting generally low bootstrap support.
