Contributions to this volume detail paleontologic research in Manonga Valley, and shed important light on the evolutionary development of eastern Africa. Chapters provide novel insights into the taxonomy, paleobiology, ecology, and zoogeographic relationships of African faunas, as well as lay the foundation for future geological, paleontological, and paleoecological studies in this important area. The book concludes with a discussion of the importance of investigations on broader geographical sites, including the Manonga Valley, for human evolution research. The text is supported by 143 illustrations.
