Peltobatrachus pustulatus (Panchen 1959; Late Permian; 70cm length) is traditionally considered a temnospondyl. Here it nests with Sclerothorax. Each rib is wide enough to touch its neighbor. Sagittal osteoderms appear as spine tables. The distal limbs and teeth are not known.
Sclerothorax hypselonotus (Huene 1932, Schoch et al. 2007; Early Triassic, 70?cm) had unusual elongate dorsal spines. The ribs had costal plates. The skull was wider than long.
