Gazella View in CoL sp. ( Fig. 7 View FIG A-D, G, H)

LOCALITY. — Quarry 3, Ivand district, north of Tabriz, Iran.

MATERIAL EXAMINED. — Two left and one right broken frontlets with horn-cores ( HMNH-IV 138-140; Fig. 7 View FIG A-D, G, H).

DESCRIPTION

Frontlet HMNH-IV138 ( Fig. 7C, D View FIG ) preserves an almost complete horn-core (80 mm above the pedicle), unfortunately broken in the middle and preserving little of the frontal or orbit. IV139 ( Fig.7G, H View FIG ) features the preserved supra-orbital fossa, but lacks the tip of the horn-core. IV140 ( Fig. 7A, B View FIG ) preserves a partial orbit and a small part of the parietal, but lacks the tip of the horn-core and has a broken inner side.

Frontlets IV139 and IV140 bear similar sizes and horn-core morphologies. The DAP and DT at the base of IV139 are 25 mm and 21.5 mm, respectively. The horn-cores are located above the orbits, moderately curved posteriorly in lateral view, and straight in anterior view. The base of the horn-core is relatively robust and laterally compressed, and the cross section diminishes greatly upwards. The maximum width lies at the anterior side of the horn-core while the posterior side is narrow. Longitudinal grooves are also present. The supra-orbital fossa is large and oval-shaped, and is located slightly towards the middle of the horn-core mid-line. The dorsal orbital rim is wide and features a postcornual fossa. Frontlet IV138 differs from the two frontlets described above in that it is less curved in lateral view and is less robust at the base; its cross section diminishes gradually from the base upwards.

COMPARISON

According to the morphology of horn-cores,the three frontlets found at Ivand locality can be separated into two groups. Frontlets IV139 and IV140 show homogenous characteristics and should be classified into one form; IV138 may belong to another form. Horn-cores IV139 and IV140 show great similarities to Gazella deperdita (Gervais, 1847) in that they fea- ture a robust base, rapidly diminishing cross section, a curved outline in the side view, and a maximum width located at the anterior part. IV138 however, is much less curved in the side view, with the cross section gradually changing from the base upwards. These characteristics fit Gazella gaudryi Schlosser, 1904 ( Arambourg & Piveteau 1929).
