Comparative histology of sculptured dermal bones in basal tetrapods, and the implications for the soft tissue dermis
The histology of the sculptured dermal bones of skull and pectoral girdle of 19 taxa of Palaeozoic and Mesozoic basal tetrapods and of the porolepiform Laccognathus is investigated. The dermal bones
THE POSTCRANIUM OF ARCHEGOSAURUS DECHENI, AND A PHYLOGENETIC ANALYSIS OF TEMNOSPONDYL POSTCRANIA
TLDR
A phylogenetic study of the gharial-like Archegosaurus decheni and 16 other temnospondyls results in a single most parsimonious tree that agrees in many aspects with cranium-based analyses: Trimerorhachis and Dvinosaurus form a basal clade (Dvinosauria), followed by monophyletic euskelians (dissorophoids plus eryopids).

ABSTRACT Morphology and ontogenetic changes in the skull and hyobranchium of the Permo-Carboniferous temnospondyl Archegosaurus decheni from the Saar–Nahe Basin (SW Germany) are described in detail,
Osteology and relationships of the temnospondyl genus Sclerocephalus
TLDR
The complete osteology of the genus Sclerocephalus is reviewed, indicating that the large temnospondyls of the Permian and Mesozoic probably formed a natural group, and that the terrestrial adaptations of Eryops and the dissorophoids probably evolved by convergence.
Sculpture and vascularization of dermal bones, and the implications for the physiology of basal tetrapods
TLDR
Dermal bone histology indicates a consolidation of the integument in basal tetrapods by strong, mineralized Sharpey's fibres in the sculptural ridges and tubercles, and by the presence of metaplastic tissue in several taxa.
LARVAL ONTOGENY OF MICROMELERPETON CREDNERI (TEMNOSPONDYLI, DISSOROPHOIDEA)
TLDR
Transformation into the adult stage took place gradually and in a longer period of time during ontogeny than in extant amphibians.
Deep-time evolution of regeneration and preaxial polarity in tetrapod limb development
TLDR
It is shown that preaxial polarity in limb development was present in various groups of temnospondyl amphibians of the Carboniferous and Permian periods, including the dissorophoids Apateon and Micromelerpeton, as well as the stereospondyomorph Sclerocephalus, demonstrating that both features were already present together in antecedents of modern salamanders 290 million years ago.

TLDR
The delayed formation of scales, scapulocoracoid, and basibranchial, in comparison with the Permo-Carboniferous temnospondyls Sclerocephalus and Onchiodon, may be correlated with the secondary aquatic adaptation of A. decheni throughout its life history.
