Family Palaeobatrachidae COPE, 1865 Genus Pliobatrachus FEJÉRVÁRY, 1917 Pliobatrachus cf. langhae FEJÉRVÁRY, 1917 (Figure 2: A-D) Material — Osztramos 1/b: 1 fragmentary frontoparietal, 1 fragmentary right ilium (HNHM. No. V.99.4). Description and comments — The dorsal surface of the frontoparietal fragment is smooth, and slighdy concave in its median part. The anterior margin was presumably trifurcated with observable evidence of overlying the sphenethmoid (SANCHÍZ 1998). The fragmentary ilium belonged to a relatively small specimen. The tuber superius, situated anterodorsally from the acetabulum, is without any trace of division into gluteus tubercle and iliofibularis-iliofemoralis attachment (as it is usually observed in Palaeobatrachus); the preacetabular fossa is lacking; the pars descendens os sis ilii (which was probably weakly defined) and the interiliac process are broken off. The basis for the assignment of the specimens to the genus Pliobatrachus was the morphology of the tuber superius and the shape of the outer surface of the frontoparietal. However, it could be mentioned that in Central Europe both genera survived up to the Upper Pliocene (MLYNARSKJ et al. 1984). In the case of Pliobatrachus the latest occurrences are from the Lower Pleistocene (SANCHÍZ 1998). Figure 2 — Pliobatrachus cf. langhae (A-D) and Eopelobates sp. (E-H) from Osztramos 1. — A, B: frontoparietal (Ol/b); C, D: ilium (Ol/b); E: sacral vertebra (Ol/c); F: presacral vertebra (Ol/c); G: humerus (Ol/c), H: ilium (Ol/c). — A, E: dorsal views; B, F, G: ventral views; C: posterior view; D, H; lateral views. Family Pelobatidae BONAPARTE, 1850 Genus Eopelobates WAGLER, 1830 Eopelobates sp. (Figure 2: E-H) Material — Osztramos 1 /b: 1 scapula, 1 vertebra, 1 sacral vertebra, 5 ilia (HNHM. No. V.99.5); Osztramos 1/c: 1 fragmentary maxilla, 2 presacral vertebrae, 2 sacral vertebrae, 2 humeri, 4 ilia (HNHM. No. V.99.6); Osztramos 1/e: 1 vertebra, 1 fragmentary humerus (HNHM. No. V.99.7). Description and comments — The outer surface of the fragmentary maxilla is covered by an incipient pit­and-ridge sculpture. The few presacral vertebrae from the posterior trunk region are procoelous, and provided with small transverse processes directed anteriorly. A peculiarity of these vertebrae is the presence of spinal nerve foramina, a character observed in Eopelobates by VERGNAUD-GRAZZINI (1970), SANCHÍZ & MLYNARSKJ (1979), and HODROVA (1987). The sacral vertebra has an extremely widened diapophyses. The sacral vertebra is not fused with the urostyle, and the sacral—urostylar articulation is monocondylar. The fragmentary ilia are of two size categories. In all the specimens the pars descendens is damaged. The humerus lacks any characters of diagnostic value.
