We present here a pilot study to examine trophic level effects and migration patterns at the middle Shang Dynasty site of Xiaoshuangqiao in Henan Province usingδD results combined withδ13C andδ15N values. A total of 33 specimens (17 humans, 7 cattle, 5 pigs, 3 sheep, 1 dog) of bone collagen were isotopically analyzed forδ13C,δ15N, anddD values. A strong positive correlation (R2= 0.94) between meanδ15N andδD values of herbivores (cattle and sheep), omnivores (pig), carnivores (dog) and humans was observed. TheδD results were found to increase by ∼10‰ to 20‰ from herbivores to omnivores to carnivorous, evidence that collagenδD results are a useful indicator for the study of trophic levels and dietary patterns at archaeological sites. TheδD results were also used to examine the origins of two different groups of individuals buried at Xiaoshuangqiao. Individuals buried in sacrificial pits of district V had meanδD values (−47.0 ± 2.9‰, n = 11) that were significantly (p = 0.049) elevated compared to the people buried in the stratigraphy of district IX (−51.3 ± 3.3‰, n = 3), indicating that they were ingesting water from different locations. In addition, the D values of the people buried in the stratigraphy were similar to the pigs (−54.5 ± 4.2‰, n = 5) at Xiaoshuangqiao, suggesting that they were most probably of the local population, and that the individuals buried in the sacrificial pits were most possibly from the coast and prisoners of the Dongyi (“东夷”) people. Thus,δD results have the potential to examine human origins and migration patterns and should be increasingly used in conjunction withδ13C andδ15N values at archaeological sites.
