| Zusammenfassung |
| Remains of the woolly mammoth (Mammuthus primigenius Blumenbach) are found all
over Eurasia except in mountainous areas of Scandinavia and in western Iberian
Peninsula. In the core area of the Scandinavian Ice Sheet, they are the only group of
animal remains to have survived until today in abundant numbers, and so are an
important source of information about the past fauna, their environment, and the
climate.
Our data include mammoth remains found in Sweden, Denmark, Lithuania, Latvia, Estonia
and Finland. Mammoth finds from northern Germany are not included in this study, but some
dates have been published elsewhere. We lack data from northern Poland, but we include
finds from southern Poland, approximately 500 km directly south of the main study area, as a
point of comparison. Approximately 300 localities with mammoth molars, tusks and bones
are known from the study area. Most of the finds (90%) are isolated skeletal elements. In
marginal areas of the SIS, in Denmark and Lithuania, associated elements are also found
together at some localities, but whole or partial skeletons are found only in southern
Poland.
The mammoth data were collected by the authors from published papers and reports as well
as by direct survey of museum collections. A total of 104 radiocarbon dates were
documented: 78 from the circum-Baltic area and 26 from southern Poland. From the dates, 73
were previously published by the authors, and eight by other researchers. A total of 23 dates
are new. Most of the specimens (93) were dated using AMS, and 11 using conventional
radiocarbon dating. Finite dates were calibrated using the download version of CalPal-2007
(Weninger et al., 2008) with calibration data set CalPal-2007Hulu (Weninger and Jöris,
2007).
The spatio-temporal distribution of mammoth remains around the Baltic Sea suggests that the
species was widely spread in north-eastern Europe during ice-free intervals of the
Weichselian glaciation. Mammoths were present in north-eastern Europe nearly continuously
from 53 ka to 11 ka, completely disappearing from the area only during the Last Glacial
Maximum (LGM). From the northern parts of the study area, mammoths disappeared ca. 27
ka ago. In the south they survived until the LGM, and occupied the area again during
deglaciation. Mammoths survived in the eastern part of the study area until the end of
Younger Dryas.
