Dissorophoideans are a clade of medium-sized, temnospondyl amphibians that appeared during the Late Pennsylvanian in Euramerica, and continued through to the Late Permian and even possibly the Early Triassic of Gondwana (if Micropholis belongs here). They are distinguished by various details of the skull,[1] and many forms seem to have been well adapted for life on land.
It has been suggested that they may be ancestral to the Frogs (Reisz, no date) or even the Lissamphibia as a whole, in which case the latter would be included in this clade.
It is possible that the small Permo-Carboniferous Micromelerpetontidae and the large Late Permian Melosauridae may also belong in this clade.
