The first appearence of this cricetid is in the 1st layer of the Tarko Rocksheiter (JÁNOSSY D. 1979, 1986), but during the Middle- and the Late Pleistocene its occurence was not continuous. Beyond the above mentioned Cricetus sp. of some Late Middle Pleistocene faunas the Cricetus cricetus was substituted by Cricetus major (WOLDRICH) in the Late Pleistocene Varbó-type faunas (JÁNOSSY D. 1979, 1986). Arvicola terrestris B, KOLFSCHOTEN, 1990 (Fig. 14.) Material and measurements 8 th layer: 2M3, 4ml; SDQ: 90.0 - 119.0 X= 101.0 7 th - 6 th layers:4ml; SDQ: 60.0 - 96.0 X= 79.4 4 th layer: IMI, 3M3, 4ml, 4m2 SDQ: 80.0 - 123.0 2 nd layer (4 th sample): 4M3, 3ml, 6m2, lm3; SDQ: 93.0-117.0 2 nd layer (2nd sample): 1M3, lm2; SDQ: 94.8 - 96.7 X= 97.5 X= 99.6 X= 95.7 Comments The systematical and biochronological importance of the enamel thickness of the Arvicola teeth was elaborated by KOENIGSWALD W. 1973, HEINRICH W. 1978, 1982, 1987, KOLFSCHOTEN T. 1990. In Hungary the method was adopted by JÁNOSSY D.1976, 1977, 1979, 1986 and HiR J. 1987, 1989, 1990. The means of the enamel thickness quotient (SDQ) of the material from the 8th layer of the Lök-völgyi Cave is very close to the corresponding parameters of the Hungarian Late Middle Pleistocene (Saalian) and Early Late Pleistocene (Eemian) Arvicola populations.
