Hír, J.: Subfossil Mesocricetus population from the Toros Mountains (Turkey) (Mammalia)

The vertebrate bone material was collected from the surface and from the uppermost 10 cm of the soil in the cave. The 40 kg soil sample was washed in sieve at the Meydan spring. The sorting of the washed material was effected in the field. The elaboration began after returning, home. The aim of this article is to give the results of the metrical and morphological investigation of the numerous Mesocricetus material from the fauna. THE MATERIAL 4 fragmentary crania and 9 maxillae with complette toothrowes, 49 max. fragm. with incomplette toothrowes, 51 M 1, 42 M 2, 39 M 3. 6 mandibulae with complette toothrowes, 23 mand. fr. with incomplette toothrowes, 66 m 1, 76 m 2, 50 m 3. METH00S The elaboration was effected by an MBS-9 -type stereomicroscope. The measurements were taken using the ocularmicromether of it to an eccuracy of 0.01 mm. The following dimensions were measured: (Fig. (3, 5, 7, 9, 11, 13) (After PRA0EL, A. 1981). I - length of the tooth crown Wa - anterior width of the crown at the protocene-pafacone height in the upper teeth end, correspondly at the protoconid-paraconid height In the lower teeth. At the M2, M3, m3 molars the Wa = W maximal Wp - posterior width at the hypocone-metacone height in the upper teeth and at the hypoconid-metaconid height in the lower teeth. At the Ml, ml molars the Wp=K maximal L M 1-3 - length of upper row of molars l m 1-3 - length of lower row of molars. The measurements obtained were used to trace l/W scatter diagrams (Fig. 4, 6, 8, 10, 12, 14) and worked aut by the basic statistical parameters: N - sample size mln.-max. - observation range X - arithmetic mean 50 standard deviation The morphological investigation based on the nomenclature of FAHL8USCH, V. (1964) and MEIN, P. - FREUOENTHAL, M. (1971). The separation of the different morphotypes is after the presence (+) or absence (-) of certain elements of the tooth crown. The extremely worned teeth are not counted into the morphological analysis. SUBSCRIPTION M 1. (Flg.3) The molar Is 4 rooted. The anterocone is always well divided and connected with the protocene. On the labial and on the lingual edge of the tooth crown there are strongly developed ridges between the anterocone and the protocene - paracone cone pairs. By the side of the anterocene there are 3 accessory conulets (Fig. 3.): the preanterocone cingulum (PAC) on the anterior side, the parastyle (PAST) on the postero-lingual side, the protostyle (PRST) on the postero-labial side. The frequency and the combination of these elements are visible on the distribution of the morphotypesi 109
