Situated at the northern extremity of the Hengduan Mountains,the upper reaches of the Dadu River is a significant area for investigating the cultural exchange between the North and the South.The excavation of the Shidaqiu site bridges gaps and provides evidences for restoring the subsistence economy of the people.This study focuses on the animal remains unearthed in 2007,and reports the AMS14C dating and Carbon and Nitrogen stable isotope data of this site.The scientific methods and other evidences all assign the settlement to the period between the Han Dynasty and the Jin Dynasty.Isotopic data from animal bones reveals that domestic pigs primarily consumed C3 food,whereas the diet of sheep and cattle was a C3/C4 mix,predominantly C3 plants.The dietary differences suggest that domestic pigs were possible pen-raised,while cattle and goats were primarily grazed with a minor supplementation of C4 food.○verall,the site's inhabitants led a sedentary lifestyle,primarily procuring food through the cultivation of triticeae crops and the rearing of livestock such as goats,cattle,and pigs.This subsistence strategy should have been formed with the strengthened cultural exchanges between the North and the South in the late Neolithic period,and was further intensified during the Qin-Han period.
