英文摘要: The unearthing in 1977 of a complete frozen carcass of a young mammoth, known as the Kirgilyakh mammoth or Dima: 1) provided the first opportunity for detailed study of the anatomy of a mammoth calf; 2) provided a more detailed understanding of interstadial landscapes; and 3) suggested paleoclimatic variability occurred in Western Beringia during marine isotope stage (MIS) 3. Limited access to early Russian literature resulted in unfortunate misinformation in English-language publications. Since then, six other juvenile carcasses have been discovered in northern Siberia and additional Late Pleistocene paleobotanical records have increased understanding of MIS2 and MIS3 environments. Given the new data, it seems timely to re-examine information about the Kirgilyakh mammoth in the context of: 1) correcting mistakes about the age and environments of the site, including the manner of the mammoth's death; 2) comparing paleoenvironmental settings with that of other young mammoth carcasses; and 3) revisiting the concept of mammoth-steppe. This re-examination, which places the Kirgilyakh results in a broader spatial-temporal setting, reinforces the idea that climatic variability, including the Kirgilyakh cool interval, characterized MIS3. Unstable landscapes in mountains and lowlands were key factors in deaths of the Siberian mammoth calves. The prevalence of tundra in MIS2 model reconstructions and abundance of paleobotanical data indicating mesic tundra and forest during MIS3 suggest that classification of these intervals as mammoth-steppe is problematic. © 2016 Elsevier Ltd. 资助项目: The Russian Foundation for Fundamental Research (15-05-06420) and the Russian Academy of Sciences (15-I-2-067) provided support during the preparation of this manuscript.
