Holocene palaeoenvironmental reconstruction based on fossil beetle faunas from the Southern Altai region, north‐west China
ABSTRACT We present here the results of the first‐ever Quaternary entomological research in China. The Halashazi Wetland, located in the southern Altai Mountain region in the northernmost part of Xinjiang Province, yielded Holocene insect fossils (mostly beetles) from two peat profiles. In total, 55...

The interval from 10 424 to 9705 cal a BP was probably a cold and wet period, and the study site was above the treeline.

Of the 37 identified beetle species from the Halashazi site, 34 (92%) have modern records in Siberia. The Altai Mountains probably served as a dispersal corridor between the Siberian arctic and alpine regions of northern China. Copyright © 2019 John Wiley & Sons, Ltd.
