... are discussed; the appendicular skeleton of Eryops is considered hypermorphic. Within the Temnospondyli, the Eryops appendicular skeleton is most similar to that of the Dissorophoidea, and most dissimilar to both the most plesiomorphic temnospondyls and the secondarily aquatic Mesozoic stereospondyls...

...David W. Dilkes Abstract Restudy of the only indisputable larval temnospondyl from the Lower Permian (Arroyo Formation: Clear Fork Group) of North America has revealed the presence of a narial flange, which supports its assignment to the superfamily Dissorophoidea. Two families of dissorophoids...

... transformation. Dilkes identified UCLA VP 3686 as Dissorophoidea incertae sedis, but he did exclude trematopids from consideration. Dissorophids (which at the time comprised dissorophids and amphibamiforms in the modern framework) were not excluded from consideration. Dilkes noted that an increased...

The historical recovery of lapillopsids as the sister group to Dissorophoidea in some previous analyses with fewer small-bodied taxa (Schoch, 2013 ; Pardo et al., 2017 ) also confers support to our hypothesis. Lapillopsis nana was originally considered to be a micropholid...
