A Comparative Analysis of Portable X-ray Fluorescence Spectrometry and Stable Isotopes in Assessing Ancient Coastal Peruvian Diets by Theresa Jane Gilbertson A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Applied Anthropology Department of Anthropology College of Arts and Sciences University of South Florida Major Professor: Robert H. Tykot, Ph.D. John Arthur, Ph.D. Arlene Fradkin, Ph.D. David Himmelgreen, Ph.D. Erin Kimmerle, Ph.D. Date of Approval: November 17, 2015 Keywords: Nasca, Lima, Moche, cultures, marine, terrestrial Copyright © 2015, Theresa Jane Gilbertson DEDICATION This dissertation is dedicated to the memory of both my mother, Betty Asher Smith and father, Lewis J. Smith, with love and profound admiration for instilling in me the belief that a dream can be fulfilled at any age. ACKNOWLEDGMENTS Many years ago as an undergraduate student, I had the profound experience of studying under the tutelage of Robert Barylski at USF Sarasota-Manatee. He pushed me towards pursuing a degree in that which I loved rather than that which was particularly practical at the time. The late Amy Sparks, remembered fondly, became my friend and adviser as I finished a Master’s Degree in the Department of Humanities and American Studies. She encouraged me to continue along my path towards a doctorate with a focus remaining on Peru. James Strange, biblical archaeologist, drew me back into archaeology, dabbled in when I had earlier lived in Peru, although when a doctoral program with an archaeology track was launched in the Anthropology Department, he encouraged me to pursue my love. Victor Manuel Olivera and his business partner, Leo Little, Margot Beyersdorff, Lynn Meisch, and many other anthropologists and archaeologists who passed through Cuzco when I lived there in the early 1980s, as well as the Bolivian researchers who befriended me, including Laurie Adelson, Arthur Tracht, Roger and Amparo Yorke, and William Siegel, are all remembered in gratitude for their encouragement. Robert Tykot, who I first studied with on the Mediterranean archipelago of Malta, drew me into bioarchaeology and worked with me through my mother’s eight year plus fight with Alzheimer’s disease, through which I was her primary caregiver. Michael Gilbertson and Antonio Zas helped me juggle caregiving, teaching as an adjunct instructor, and continuing slowly on my pursuit of this degree. Christian Wells guided me through SPSS statistics. I am especially grateful to David Himmelgreen, John Arthur, and Erin Kimmerle, who agreed to serve on my committee, as well as Arlene Fradkin, the zooarchaeologist with whom I had the pleasure of working with while under the direction of James Strange in Israel during both the 1996 and 1999 excavation seasons. Ryan Williams of The Field Museum holds a place of honor in this dedication for being the first to finally accept my request for samples for destructive analysis in order for this dissertation to proceed. Christopher Philipp, Collections Manager at The Field, also was instrumental in allowing me access to that which I needed on two sampling trips to their halls. In the Smithsonian Museum, it was David Hunt who granted me the permission for the pXRF non- destructive analysis that allowed me to include a portion of the Hrdlicka collection of Moche crania in this report from at least the perspective of an elemental analysis. My host family while working at The Field Museum in Chicago was that of Eileen and James Ross, and while working in Suitland, Maryland, at the Smithsonian Research Center, I thank Karen-Ann Lichtenstein and her husband, James Luceno. I am grateful to Ethan Goddard, the Lab Director at USF St. Petersburg who processed my samples. Fawn Ngo and Richard Reiche, professors of criminology and psychology, respectively, friends and coworkers at USF Sarasota-Manatee, and Rheta Lanehart, Tampa campus, all helped to refresh my memory of SPSS as I worked through the data. I also want to thank Mike Sutherland, Professor Emeritus from the University of Massachusetts Amherst and currently with New College of Florida, for being a reader and one who kindly checked my statistics. My final thanks are to Michael Gilbertson for his time and expertise in editing, and to Antonio Zas, who is responsible for drawing, or redrawing from Kroeber’s original maps, all of the maps used in this paper.
