Pelobates View in CoL sp. ( Fig. 9 View FIG )
MATERIAL EXAMINED. — Three maxillae ( ISER Tt-0390/- 1-3), one squamosal ( ISER Tt-0391), one presacral vertebra ( ISER Tt-0392), one scapula ( ISER Tt-0393), one ilium ( ISER Tt-0394).
DESCRIPTION
Maxilla
The bone is covered on its labial surface by a pit and ridge sculpture ( Fig. 9 View FIG A-B’). Most ridges tend to have a longitudinal orientation; they are less
elevated and even absent near the orbital margin and

on the pars dentalis. In a smaller individual (ISER Tt-0390/3) the sculpture is less prominent.
Squamosal
The only specimen preserves most part of the processus posterolateralis, a minute fragment of the lamella alaris and the base of the processus zygomaticus. The processus posterolateralis is strongly curved laterally and displays a medial groove delimited by bony lamellae.The remnants of the lamella alaris and processus zygomaticus is covered dorsally by a pit and ridge sculpture.
Presacral vertebra
The only vertebra is procoelous with a relatively short centrum; the cotyle and condyle are slightly flattened dorsoventrally. In dorsal view the anterior margin of the neural arch is deeply indented, while the tip of the neural spine does not exceed the posterior margin of the postzygapophyses ( Fig. 9C View FIG ). The spinal nerve foramen is absent.
Ilium
The bone is fragmentary and most of the acetabular part is broken off ( Fig. 9D View FIG ). The iliac shaft is curved ventrally and slightly medially and the iliac crest is reduced to a ridge of very low height. A weak waisting is observed between the acetabulum and the iliac shaft; the remnant of the so-called spiral groove ( Evans & Milner 1993) is also present.
REMARKS
The morphology and pattern of sculpture on the maxilla and squamosal is highly typical for the genus Pelobates . On the other hand, due to the fragmentary state of the available material a more precise assignment of the fossils was not possible.
