Abstract
This study presents the first proteomic evidence of yak milk consumption, dating back to the 13th century. Analysis of human dental calculus from elite individuals in Mongolia revealed yak-specific milk proteins, highlighting the importance of yak dairy in the Mongol period and local resource control. The exceptional preservation in permafrost sites also allowed identification of a diverse range of other proteins from milk, tissue, and blood, providing insights into diet and resource use.
