ABSTRACT
The Crow Creek cranial sample is important because there are no other large Middle Missouri Region cranial samples as early or as far south as Crow Creek. Crow Creek is important because it links the earlier Central Plains Tradition with the later Arikara samples both geographically and temporally. All relatively complete Crow Creek skulls were reconstructed by Mark Swegle and Willey during January 1979. The outlier analysis is performed using the principal component scores of cranial measurements to determine if morphologically dissimilar skulls were present in the ditch. The principal component scores for each individual are employed. In addition to these analyses of variation within the Crow Creek sample, skulls are used to estimate morphological distances between Crow Creek and those from other sites. Ossicles are isolated pieces of bone in sutures which are large enough to be observed without difficulty.
