Strontium, oxygen, and carbon isotopes were measured in human tooth enamel from 66 burials in 9L-22 and 9L-23 residential groups at the Classic Maya site of Copan in western Honduras. These results are discussed in relation to earlier studies at Copan and baseline measurements from the surrounding region and the Maya area in general. Nearly 50% of the individuals are identified as non-local based on combinations of strontium, oxygen, and carbon isotope ratios. They came from a variety of places in the Maya area. This migratory pattern at the 9L-22 & 9L-23 residential complex from the Early to Late Classic (ca. 400–800 CE) is compared with 10J-45 sector from the mainly Early Classic occupation (ca. 400–650 CE) and an interesting change is noted. The social privileges observed among the Early Classic immigrants from the north Maya Lowlands were apparently revoked in the Late Classic. New immigrants, probably from the “non-Maya” regions of Western/Central Honduras, appear to have gained those social privileges. High-status Honduran individuals in the urban core suggests a strategy by the Copan dynasty in the Late Classic that incorporated the emerging “non-Maya” elites from Western/Central Honduras.

在洪都拉斯西部科潘的Classic Maya地点的9L-22和9L-23居住群体的66个墓葬中，从人的牙釉质中测量了锶，氧和碳同位素。这些结果与Copan的早期研究以及周围区域和Maya区域的基线测量值进行了讨论。根据锶，氧和碳同位素比的组合，将近50％的人被确定为非本地人。他们来自玛雅地区的许多地方。从早期到晚期经典（约公元400-800年）的9L-22和9L-23住宅区的这种迁移模式与主要是早期经典职业（约400-650 CE）的10J-45区域进行了比较。注意到一个有趣的变化。在北玛雅低地地区的早期经典移民中观察到的社会特权显然在经典后期被撤销。可能来自洪都拉斯西部/中部“非玛雅”地区的新移民似乎已经获得了这些社会特权。处于城市核心地位的洪都拉斯高地位人士建议说，科潘王朝在后期经典中提出了一项策略，其中纳入了来自洪都拉斯西部和中部的新兴“非玛雅”精英。
