This thesis specifically examines prehistoric shell artifacts recovered from excavations at Wupatki Pueblo, an Ancestral Puebloan site located in northern Arizona. The shell artifacts from Wupatki Pueblo were analyzed in order to accurately determine the genus and species, artifact types, and uses of shell. By looking at manufacturing techniques, this research determined if the Hohokam traded or brought shell artifacts to Wupatki Pueblo as finished products or if shell manufacturing occurred at Wupatki Pueblo. To determine the significance of shell artifacts at Wupatki Pueblo, the shell assemblage was compared to shell assemblages from Sinagua sites and Hohokam shell manufacturing sites. Ultimately, this research adds valuable information about trade, migration, and social networks between the Hohokam, Sinagua, and Ancestral Puebloans, which is important to the understandings of function, complexity, ideology, adaptation, resilience, and the foundation of modern Pueblo cultures.
