Report on the Osteological Assessment of the "Kennewick Man" Skeleton (CENWW.97.Kennewick)
Joseph F. Powell and Jerome C. Rose

Figure 1

Figure 1 shows a the skeletal element recovery patterns for the Kennewick remains as compared with those for skeletal elements from three natural contexts: remains from water deposits such as rivers and lake, beach deposited remains, and remains scavenged by canids. The skeletal elements are provided on the x axis of the chart and from left to right are: Cranium, Mandible, Cervicle, Thoracic, Lumbar, Sacrum, Sternum, Clavicle, Scapula, Humerus, Radius, Ulna, Hand, Pelvis, Femur, Tibia, Fibula, and Foot. Each type of remains is shown using a different symbol on the graph. The Kennewick remains are a solid line. The beach remains are depicted as red diamonds, the water remains are squares, and the canid remains are triangles. Powell and Rose also compared the Kennewick recovery pattern with another natural pattern (bear scavenged remains) and a cultural one (intentional burials).

Statistical test results (Kolmogorov-Smirnoff two-tailed test) are presented in Table 4 and suggest that the Kennewick pattern could not be distinguished from the pattern of an intentional burial, yet was different from the natural patterns. Specifically, the sternum was the only major skeletal element missing from the Kennewick remains, while the natural patterns all reflect variable levels of recovery. By contrast, Powell and Rose note the sternum has been recovered in 40% of the canid scavenged remains and 80% of the patterns associated with rivers and lakes.
