M a t e r i a l. One angular, one ilium, EUNHM PV- 13228, 13229, Mercan 1, late Pliocene, MN 16; one angular, one ilium, EUNHM PV-13230, 13231, Mercan 2, Early Pleistocene, MN 17; one ilium, EUNHM PV-13232, Nasrettinhoca 1, early Pliocene, MN 14; one ilium, EUNHM PV-13233, Hamamkarahisar A, early Pliocene, MN 14; three ilia, EUNHM PV-13234, 13235, 13236, Hoyhoytepe 1, 2, and 3, late Pliocene, MN 16.
D e s c r i p t i o n. The angulars are preserved only as small pieces including the coronoid process. The specimens are somewhat sinuous. The coronoid process is prominent having a concave dorsal surface with weak rugosity. The crista mandibulae externa is sharp. Laterally, the bone has a deep depression above the crista mandibulae externa. The groove for Meckel’s cartilage is wide but markedly constricted at the level of the coronoid process. The coronoid process is rectangular and crinkled dorsally. All ilia are fragmentary, having only the anterior part of the acetabular portion and posterior part of the shaft. The dorsal crest, pars ascendens and pars descendens are mostly missing. The supraacetabular and tubercular fossae are well developed and relatively wide. In the best preserved ilia the dorsal tubercle is robust and prominent. It is located anteriorly to the acetabulum. In the posterior half of its length the dorsal tubercle is distinctly thickened. Laterally the dorsal tubercle is flattened.
R e m a r k s. The specimens are assigned to the genus Pelophylax based on the sharp crista mandibulae externa, dorsally crinkled coronoid process of the angulars and laterally flattened dorsal tubercle of the ilia (see Bailon 1999, Böhme 2001, Ratnikov 2001). In Turkey several living species of Pelophylax ( P. caralitanus (ARIKAN, 1988) , P. bedriagae (CAMERANO, 1882) , and P. ridibundus (PALLAS, 1771)) and one fossil species ( Pelophylax barani (RÜCKERT- ÜLKÜMEN, 1980)) are distinguished. Due to the poorly known or missing osteological characteristics of the extant species, it is currently impossible to determine to which of them the specimens from Mercan 1, 2, Nasrettinhoca 1, Hamamkarahisar A and Hoyhoytepe 1, 2, and 3 should be referred.
