There is a single dormouse tooth in the whole material (from the layer 5), this is a fourth upper premolar (P 4 ). It is round shaped and has two roots, an ante­rior narrower and a posterior thicker one. According to the measurements (L= 1.35 mm, W= 1.55 mm) it is an edible dormouse premolar (Glis glis L.). The tooth is rather worn, so we are not allowed to preclude the possibility of mixing by redeposition. I classified also on the basis of LAV datas the hamster remains into the Crice­tulus migratorius Pallas species (Fig. 7). This classification is apparently inconsis­tent with the Riss-Würm age, because in the Hungarian faunas this species is known since the Early Würm, however in Bulgaria it was found from the end of the Günz-Mindel Interglacial, too (lowermost part of Middle Pleistocene), to­gether with Allocricetus bursae Schaub (Popov 1988). Among the vole lower first molars there are 12 M l of Arvicola. Studying their enamel thickness I determined them as Arvicola terrestris L. species. On the teeth the enamel was thicker at the anterior wall of triangles and it was thinner at the posterior walls. By a broken M x from layer 5 the enamel thickness was equal, hence in this case also the Arvicola canúana-terrestris determination is possible. Measuring the length of the molars, they fell into the Late Pleistocene large size­category (Jánossy 1986, p. 113). (Table 5) Very important fact is the presence of the steppe lemming (Lagurus lagurus). The five M b collected from Tbkod, show theL. lagurus type morphology without exception; the "Pitymys-rhombus" is absent, the anterior caps are deeply impressed laterally, hence the T6 and T7 are well developed. At one part of the specimens these triangles are situated symmetrically to the longitudinal axis, at their other part the T7 is placed more anteriorly, the cap is assymmetrical. In the case of the Mi from layer 6 the T6 is rather isolated. These forms (Fig. 8) are not characteris­tic in stratigraphical aspect. One can find such variants for example in the materi­al of Ördöglyuk Cave at Solymár (end of the Middle Pleistocene) or at Subalyuk Cave (Late Pleistocene, Lower Würm) and such forms were described also from the upper part of Mindel Glaciation from Dobrogea in Romania (Radulesco & Samson 1974, p. 120, and fig. 1/6 on p. 119). More interesting is the fact that 1 mm « 1 Fig.8: Lagurus lagurus first lower molars from Tbkod, 1-2: Tbkod II/l, V.9 1.109, 3: Tokod II/4, V.91.187, 4: Tbkod II/6, V.91.294
