Abstract In this dissertation, I examine the representation of projectile points in the Middle Stone Age (MSA) and Later Stone Age (LSA) of Tanzania, and the way in which such tools were used over time and space. This study reviews the different strategies used to produce points during the MSA and LSA. It also examines the mechanisms involved in raw material procurement, hafting technology, and the use of these tools as projectile weapons and how they evolved over time. It is clear that there were different kinds of multi-weapon systems in use in Tanzania during the MSA, LSA and the transition between them. The points examined here are from three archaeological sites: Mumba, Nasera and Magubike. The samples analysed here reveal that triangular blanks were preferred for the production of points. Most of them were modified on their proximal ends to provide a suitable binding portion for hafting as well as for aerodynamic movement. Results from the Tip Cross Section Area (TCSA) and weight values suggest that spear and arrow projectiles coexisted in these three sites during the MSA and MSA/LSA transition. Both local and exotic rocks were used for the production of points. In previous studies, the appearance of exotic rocks in the archaeological assemblages was correlated with trade and exchange. But here the use of exotic rocks seems to be influenced by functional values such as durability, sharpness and brittleness. Sharp and durable rocks such as chert and quartzite were needed for spears because of their high compression strength. This makes them better able to withstand unintentional breakage after being stressed by the force of impact. Points made of brittle rocks, such as quartz and obsidian, were mainly used for light duty projectiles such as throwing spears (darts) and arrows, because they penetrate the body of an animal better and sometimes break more easily. The presence of points made of exotic or local rocks shows that functional variables were important for projectile technologies. The overall morphological and technological patterns revealed in this study suggest that foragers who made and used points had elaborate technological skills, abstract thinking and developed behavioural capability similar to those of other modern foragers. Acknowledgements The success of this dissertation is due to the efforts and support of a large number of people and institutions, all deserving of my appreciation. Any academic merit in this study owes much to the guidance of my advisor, Dr. Pamela Willoughby. Throughout my study and field research, she has been a true advisor and supporter, providing substantial ideas and suggestions for my studies. The criticisms she made of my work and writing have been genuine and legitimate. Always she has been a true friend, ready to help, to answer questions, and to give advice. Special thanks go to the members of my supervisory committee. I am thankful for their inspiration and ideas, and that I have had the great opportunity to have studied with them. Every member of the supervisory committee has provided essential advice and assistance. I wish to thank Dr. Raymond Le Blanc and Dr. Christopher Fletcher for their advice. Different institutions provided important and much appreciated financial support. First, I would like to thank the Wenner-Gren Foundation for giving me a Wadsworth International Fellowship for three years as well as a Dissertation Write-up Fellowship. Second, my sincere thanks go to the Department of Anthropology and the Faculty of Graduate Studies and Research at the University of Alberta for their support through a Provost Doctoral Entrance Award, Graduate Interim Tuition Awards and Graduate Research and Teaching Assistantships. Field research was supported by the University of Dar es Salaam, through a Research and Publication Grant, by the University of Complutense, Madrid, through a UCM Cooperation Grant and the University of Alberta through a SSHRC (Social Sciences and Humanities Research Council of Canada) Standard Research Grant held by my supervisor. Together, these fellowships and grants made my studies possible and successful. Thanks are also due to the Antiquities Department, Ministry of Natural Resources and Tourism, Government of Tanzania, and the Tanzania Commission of Science and Technology (COSTECH) for granting research clearance and for providing permits to borrow artefacts for study at the University of Alberta and to the Regional Community Museum, Madrid for laboratory analysis. I would also like to thank the Vice Chancellor of the University of Dar es Salaam who approved a leave of absence from my position so that I could study for my PhD. Thanks are also due to my colleagues, the members of the Department of History and Archaeology, University of Dar es Salaam, for their encouragement and interest in my research. Special thanks are owed to Dr. Audax Mabulla for his kindness, encouragement, advice, and endless support and care of my family while I was abroad. I would also like to convey my appreciation to all the members of my family. I acknowledge the deprivations that they have endured in my absence. I would like to thank Dr Manuel Dominguez-Rodrigo and other members of the Olduvai Research Project for their support and encouragement during my field research at Olduvai Gorge and in the Lake Eyasi basin. I would also like to express my gratitude to Ms. Márquez Balén for her enthusiastic work on microscopic usewar analysis for the sampled points from Mumba. I appreciate her generosity for endless consultations. My field work in Iringa was largely supported by my supervisor and was facilitated by the hospitality we encountered from the people of that region. The field work could not have been accomplished without the help of a large number of people. Among these are Mrs. Joyce Nachilema, Iringa District Cultural Officer, Mr. Marungu, our driver, Mr. Frank Masele, Mr. Emmanuel Bwasiri and Mr. Peter Abwalo, Antiquities representatives during my field work at Olduvai and Iringa. Thanks also go to my fellow graduate students and colleagues Katie Biittner, Katherine Alexander and Ben Collins, for their tireless work during our field survey and excavations. Should anyone’s name have been omitted, it does not reflect on their contributions, but on my involuntary oversight. Table of contents Chapter 1. Introduction 1.1.
