ACKNOWLEDGMENTS There are many people whose contributions and assistance made this thesis possible. To thank all of them would require a second thesis worth of space, but this thesis would not be complete without recognizing a few of them. Firstly, I would like to thank my parents, Nathan and Susan Ramsey, for their constant support and for instilling in me a love for history and the natural world. Secondly, I would like to thank Dr. Kilby for offering me the opportunity to work at Bonfire Shelter and be a part of the long history of research carried out at such an incredible site. I would also like to thank the other members of my thesis committee: Dr. Black for sharing with me his years of experience and insight and Dr. Jacobson for her willingness to teach me zooarchaeology and her patience with me along the way. I also owe a huge debt of gratitude towards my undergraduate professor, Dr. Ashley Lemke, for introducing me to the wonders of archaeology and for continuously going out of her way to help me on my academic journey. iv TABLE OF CONTENTS Page ACKNOWLEDGMENTS ................................................................................................. iv LIST OF TABLES ........................................................................................................... viii LIST OF FIGURES .............................................................................................................x CHAPTER I.
