MATERIAL AND MEASUREMENTS. — Küçükçekmece West: right horn-core MNHN.F.TRQ628 (L = c. 60 mm, HCBTD = 16.0 mm, HCBAPD = 16.4 mm). Küçükçekmece East: right horn-core ITU 351 (HCBTD = 17.4 mm, HCBAPD = 18.4 mm); horn-core ITU no No. (HCBTD = 18.0 mm, HCBAPD = 18.2 mm); rolled horn core ITU no No. (HCBTD = 17.1 mm, HCBAPD = 20.9 mm); part of left mandible with m1-m3, ITU 370 (m1: L = 9.1 mm, W = 5.0; m2: L = 9.4 mm, W = 5.2; Lm1-m3 = 30.6 mm).
DESCRIPTION AND REMARKS
The preserved horn-cores are short, straight or faintly curved backwards and circular in cross section with a well-marked posterior longitudinal furrow ( Fig. 8A, B View FIG ). The pedicles are high anteriorly compared to the horn-core length. The postcornual groove is round and moderately deep and the supraorbital foramens open into oval depressions. The lower molars lack mesial folds or basal pillars and their lingual wall is slightly undulated ( Fig. 8C View FIG ). The hypoconid is angular and both the hypoconid and the protoconid direct distally.The third lobe of m3 is singlecuspid, round and large relatively to the tooth size.
Malik & Nafiz (1933) referred several teeth and horn-cores from Küçükçekmece East to the genus Gazella but as this material has been lost, a direct comparison is not possible. Nonetheless, a left horn-core illustrated by these authors under the binomen G. gaudryi Schlosser, 1904 ( Malik & Nafiz 1933: pl. XII, fig.1) looks identical with those described here. The general morphological and metrical characters of the Küçükçekmece West gazelle is strongly reminiscent of Gazella ancyrensis Tekkaya, 1973 from the MN9 assemblage of Yassiören, Middle Sinap, Turkey. The relatively high pedicles, the weak medio-lateral compression, the short horn-cores with small diameters ( Fig. 9 View FIG ) and the near absence of curvature are distinctive features of G. ancyrensis and usual characters of early Gazella (or Gazella -like; e.g., Bouvrain 1997: 9; Gentry 2003: 361) populations recovered from several Vallesian to early Turolian mammal assemblages of SE Europe and beyond ( Tekkaya 1973; Köhler 1987; Bouvrain 1997; Gentry 2003; Kostopoulos & Bernor 2011).
