    LIBS and LA-ICP-MS were utilized for microspatial analyses of a fossil bear (Ursus arctos) tooth dentine. The distribution of selected trace elements (Sr, Ba, Fe) was measured transversal cross section of canine tooth. These elements tracers were recognized and it is possible to say, that these elements are changing its concentration in according to the seasonal increments of dentine. The concentration is lower in winter, when the bear is in his hibernation, contrary to summer, which is affluent for its substances. Secondly, concentration of Sr shows us a seasonal migration between the place of hibernating and territory where bear searched for feed. From measurement of concentrations it is possible to claim, that the bear was hunted in his season of searching for feed, when he was ensuring his fat reserve for winter.
