- Rhinocerotinae indet. (Fig. 5 S-U) LOCALITY. — Quarry 3, Ivand district, north of Tabriz, Iran. MATERIAL EXAMINED. — Femur (HMNH-IV 137; Fig.5 S- U; Table 2). DESCRIPTION An almost complete left femur is preserved (Fig. 5 S- U). In the proximal part, the femoral head (caput femoris) and trochanter major are missing. The A Hipparion sp. large Ivand H. giganteum Gromova, 1952 Grebeniki H. primigenium Meyer, 1833 Inzersdorf H. prostylum Gervais, 1849 Saloniki H. sp. Large Samos H. brachypus Hensel, 1862 Pikermi H. mediterraneum Roth & Wagner, 1855 Pikermi H. moldavicum Gromova, 1952 Tarakilia H. proboscideum Studer, 1911 Samos Hipparion sp. large Ivand H. moldavicum Gromova, 1952 H. gettyi Bernor, 1985 H. campbelli Bernor, 1985 H. prostylum Gervais, 1849 third trochanter is broken, but the basal part is preserved. The diaphysis becomes stockier distally from the third trochanter. The distal end is well preserved, and only the posterior and anterior sides are abraded. The medial and lateral trochleas are at the same level. The trochlear trough is damaged. The two condyles somehow diverge downward and the medial condyle is higher in elevation. The intercondyloid fossa is filled with sediment. COMPARISON Figure 6A shows the scatter plot of the femoral length against the distal width of well-preserved rhinocerotid femurs from several localities in Greece, Turkey, Iran, and China. The femur from Ivand locality, as illustrated, is clearly distinct from those of Chilotherium wimani Ringström, 1924 and C. persiae Pohlig, 1887 which are smaller, slenderer, and less massive (Deng 2002). The femur IV137 clusters among the material assigned to Ceratotherium neumayri (Osborn, 1900) and Stephanorhinus pikermiensis (Toula, 1906) from eastern Mediterranean localities such as Pikermi, Maragheh, and Akkaşdaği (Fortelius et al. 2003; Antoine & Saraç 2005). In general, the femur of these species is about 50 cm long and 15 cm wide distally. The total length of the Ivand femur, due to its missing proximal end, is unknown but it is estimated to be about 45 cm. Therefore, the rhinocerotid femur from Ivand locality can be assigned to Ceratotherium neumayri / Stephanorhinus pikermiensis primarily by size. Order PROBOSCIDEA Illiger, 1811
