Parallel chemical analyses of ribs and femurs from the Middle Woodland Gibson site and the Late Woodland Ledders site show that the elements most closely related to diet (strontium, zinc, magnesium) are found in identical proportions in the two bones. Elements associated with soil contamination (iron, aluminum, potassium, manganese) are found in a significantly higher proportion in the rib. The major elements calcium and sodium are found in lower levels in the ribs. Thus the rib is more sensitive to diagenetic processes that alter elemental proportions than is the femur. Conclusions concerning subgroupings by sex or site, derived from the diet-related elements (Sr, Zn, Mg), were found to be essentially the same for the rib and the femur.
对中世纪林地吉布森遗址和晚期林地莱德斯遗址的肋骨和股骨进行的平行化学分析表明，与饮食关系最为密切的元素（锶、锌、镁）在这两块骨头中的比例相同。与土壤污染相关的元素（铁、铝、钾、锰）在肋骨中的比例明显更高。主要元素钙和钠在肋骨中的含量较低。因此，肋骨比股骨对改变元素比例的成岩作用更敏感。从与饮食相关的元素（锶、锌、镁）得出的关于按性别或遗址进行分组的结论，在肋骨和股骨上基本相同。
