This paper provides new information about the social structure of the Late Classic (ad 600–800) Maya by using stable isotope analysis to analyze dietary practices and migration histories of 22 elite individuals from three residential compounds at the archaeological site of Chinikiha in Chiapas, Mexico. The research assess whether intra-elite social differentiation was practiced through consumptive practices and simultaneously explores residential histories of individuals in the sample. Diet is determined by carbon- and nitrogen-stable isotope analysis of both bones and teeth; residential mobility is studied by stable oxygen isotope analysis. The results find no significant differences in stable isotope values between the sexes, between residential compounds, or between individuals with different burial treatments. However, children may have had diets with higher maize consumption than adults. Additionally, three individuals with childhood locations outside of Chinikihá are identified. This study contributes a nuanced understanding of the social structure of the ancient Maya elite, and at least in the case of Chinikiha, suggests minimal intra-household status differentiation in terms of diet.

本文提供了有关晚期经典（ad的社会结构600–800）玛雅人，通过使用稳定同位素分析来分析墨西哥恰帕斯州奇尼基哈考古现场来自三个居住区的22名精英个体的饮食习惯和迁徙历史。该研究评估了是否通过消费实践来实现精英内部的社会分化，并同时探索了样本中个人的居住历史。通过骨骼和牙齿的碳和氮稳定同位素分析确定饮食。通过稳定的氧同位素分析研究了居民流动性。结果发现，男女之间，居住的化合物之间或经过不同埋葬处理的个体之间的稳定同位素值无显着差异。但是，儿童饮食中的玉米消费量可能比成年人高。另外，确定了三个在奇尼基哈（Chinikihá）以​​外有童年生活的人。这项研究有助于对古代玛雅人精英的社会结构有细微的了解，至少就奇尼基哈而言，这表明在饮食方面家庭内部地位差异最小。
