Abstract: | Using incremental patterns in tooth cementum is a powerful tool for age assessment. Recent developments have shown that the method has a large potential as an indicator of the season of death of the individual in question. In this paper, the results of a study comparing thin sections of teeth of the modern Hardangervidda reindeer population to those of Iron Age, eleventh, and thirteenth century reindeer hunting stations from the same area are presented. The tooth wear stages were compared to the actual age of the individual (based on the number of incremental lines and the age at eruption). It was established that in the studied reindeer populations wear stages sometimes result in too low an age estimate. Having identified the start of the period of deposition for rest lines in the modern reindeer population as early autumn and winter, analysis of the outermost layer in the tooth cementum at the archaeological sites points to a prolonged hunting season in the thirteenth century, while in the earlier phases hunters were probably present on fewer and shorter visits. |
