New evidence for early human activity in Shigatse, Southern Tibetan Plateau during Late MIS3 epoch

Tibetan Plateau (TP) is a hotspot for early human history research. However, there is limited evidence of prehistoric human activity on southern TP, and the validity of these dates requires additional investigation. Here, we present 21 AMS ¹⁴C dating results of bones collagen and charcoal remains from a newly discovered lithic site (including paleolithic and microlithic) in Shigatse, Yarlung Zangbo River Valley basin, southern TP. The dating results for collagen and charcoals show strong conformity. These two Our extensive chronological data reveal that people occupied in the Yarlung Tsangpo River basin from 960 to 680 cal yr B.P, 2730 to 2370 cal yr B.P, and 29110 to 23090 cal yr B.P. To the best of our knowledge, our new finds provide the first evidence for early human activity in the Southern TP during Late MIS3 epoch.
