Peltobatrachus pustulatus was named by
Panchen (1959) [Amphibia with distinctive pustular ornament on the dermal bones.
Skull about 15 em long, broad, apparently parabolic in outline. Skull table long, the raised orbits being about halfway along the length of the skull. Cheek broad and smoothly curved. Occipital condyle single. Occipital surface sloping slightly back from the skull table. No intertemporal bone. Large supratemporal just reaching the border of the short otic notch, and having a wide suture with the interparietals; so that the tabular is widely separated from the parietal. Tabular bearing a large globular horn. Circumorbital bones large; lacrimal apparently excluded from the orbit. Quadrate articulation apparently slightly anterior to the corner of the skull, so that the latter forms adistinctquadratojugal horn. Large interpterygoid vacuities separated by a slender processus cultriformis. Short basicranial suture between the parasphenoid and pterygoid. Parasphenoid and pterygoid ornamented with small denticles. Distinct backwardly-directed quadrate ramus of the pterygoid. Neurocranium heavily ossified: massive cylindrical sphenethmoid extending far anteriorly; ossified basioccipital and supraoccipital; tabular and exoccipital separated by a long paroccipital process but meeting dorsal to the deep post-temporal fossa. Lower jaw ornamented laterally and bearing a well-developed retroarticular process. Dorsal vertebrae consisting of single elongate, notochordal centra, bearing 'intervertebral' neural arches. Neural spines high and conical. Rib articulation terminates a wide massive transverse process formed by the diapophysis of the neural arch combined with the parapophysis of the centrum in front of it. Caudal vertebrae of pleurocentra and small crescentic intercentra bearing haemal arches. Anterior pleurocentra open ventrally, posterior pleurocentra complete notochordal rings, finally becoming fused to the neural arches. Ribs bearing capitulum and tuberculum at the end of an undivided shaft. Dorsal ribs massive, curved, bearing posteriorly a broad surface for the dermal armour. Caudal ribs forked distally. Scapulocoracoid very broad antero-posteriorly and with a deep coracoid plate. Four foramina in the glenoid region. Cleithrum splint-like ventrally, clasping the front of the scapula blade and overlapping the clavicle anteriorly but not laterally. Humerus broad, tetrahedral and well-ossified. Pelvic girdle with a deep puboischiadic plate and deep symphysis anteriorly. Slender iliac shaft borne on a single highly adapted sacral rib. Massive dermal trunk armour of dorsal pectoral and pelvic shields, separated by overlapping bands of sutured scutes, divisible for at least some of the trunk into neural and flanking costal series. Apparently a flexible ventral armour of minute gastralia. Tail region also armoured dorsally with sutured scutes.]. It is a 3D body fossil. Its type locality is
B4, Katumbi Vawili (Lower Bonebed K6), which is in a Wuchiapingian terrestrial horizon in the Usili Formation of Tanzania.
