MIS 3 mammoth remains from Sweden - implications for faunal history, palaeoclimate and claciation chronology

Research output: Contribution to journalReview article

Abstract

The distribution of low-arctic megafaunal remains in time and space from the area previously covered by the Scandinavian Ice Sheet(SIS) suggests the presence of breeding mammoth populations in the circum-Baltic region during the time interval from 44 to 26 ka ago. The transport history of 30 mammoth teeth and bones from southern and north-central Sweden was estimated and the remains were subjected to osteological analyses and 14C dating. Oxygen isotope analyses of tooth enamel indicate a palaeoclimate considerably more homogenous than that experienced in Sweden today, showing moderate north–south gradients in the d18O value of precipitation and temperature. In general, the results support the model of restricted ice sheet distribution during the second half of the Middle Weichselian. The clear discrepancy in the inferred absence of glaciation in the central Swedish uplands and the Baltic basin as evidenced by the Swedish mammoth data versus the Danish OSL-based glaciation chronology in the period from 40 to 30 ka ago is discussed in the light of radiocarbon calibration and glacial dynamics.
