A new terrestrial palaeoenvironmental record from the Bering Land Bridge and context for human dispersal
Palaeoenvironmental records from the now-submerged Bering Land Bridge (BLB) covering the Last Glacial Maximum (LGM) to the present are needed to document changing environments and connections with the dispersal of humans into North America. Moreover, terrestrially based records of environmental chan...
