The former includes horse's, cattle's, dog's and pig's bones; the latter, brown bear's, wolf's, horse's, deer's and roe deer's remains. In the present paper, the authors report their analysis of the traces on the surface of animal bones, the making techniques of the bone and antler objects, the proportion of animal husbandry to hunting reflected from the site, and the then natural-ecological settings. These researches resulted in the achievement of a great amount of important information on man's action and other fields.
