This study sought to examine the paleodiet and temporality of a Middle Woodland group from five sites in north central Kansas. This goal was accomplished by submitting 21 samples for stable isotope ratios analysis (SIRA) and 12 samples for bone collagen AMS radiocarbon dating. Results of AMS radiocarbon dating indicated a temporal range of cal. 349 B.C. to A.D. 376. Results of SIRA indicated mixed dietary patterns. Through visual assessment and statistical analyses, it was determined that their dietary patterns formed two clusters. Cluster 1 was defined by low stable carbon and nitrogen values and Cluster 2 was defined by high stable carbon and nitrogen values. Results were interpreted in terms of flora and fauna from the archaeological record of nearby contemporaneous sites. Other causal factors for stable isotope distribution were taken into account, including paleopathology, sex and age, time, social stratification, and multiple group usage. Based on the evidence available, it was determined that stable isotope ratio distribution was caused by limited nutritional stress, and a varied consumption of fauna and flora.
