To better understand the characteristics of coffin materials during the Han Dynasties in Inner Mongolia, we conducted wood identification on 76 burial utensils from the Jihulangtu Xiongnu cemetery (dating from the late Western Han Dynasty to the Eastern Han Dynasty). The results show that the wood used were Pinus sp., Betula sp., Larix sp., and Ulmus sp., with Pinus sp.being the predominant material, accounting for 80% of the total. This preference likely reflects the composition of local vegetation. Based on the archaeological context of the samples, there was no significant difference in the choice of wood materials used for burial utensils among tombs of different ranks, suggesting that this pattern may have been shaped by the burial customs of Xiongnu, or constrained by the availability of local wood resources.
