The second volume in a series dedicated to fossil discoveries made in the Afar region of Ethiopia, this work contains the definitive description of the geological context and paleoenvironment of the early hominid Ardipithecus kadabba. This research by an international team describes Middle Awash late Miocene faunal assemblages recovered from sediments firmly dated to between 5.2 and 5.8 million years ago. Compared to other assemblages of similar age, the Middle Awash record is unparalleled in taxonomic diversity, composed of 2,760 specimens representing at least sixty five mammalian genera. This comprehensive evaluation of the vertebrates from the end of the Miocene in Africa provides detailed morphological and taxonomic descriptions of dozens of taxa, including species new to science. It also incorporates results from analyses of paleoenvironment, paleobiogeography, biochronology, and faunal turnover around the Pliocene-Miocene boundary, opening a new window on the evolution of mammals, African fauna, and its environments.

About the Book
Reviews
"The late F. Clark Howell had a vision of paleoanthropology as a fully integrated set of many scientific disciplines. This meticulously documented work is the first in a series that fulfills his vision. It is a magisterial synthesis of important early hominid fossils and their contemporaneous mammals placed in regionally dated stratigraphic sequences and reconstructed paleoenvironments. It is enhanced by images of sites and moments of discovery that are usually left to popular articles and that will give the reader a glimpse of the rigors of field work in a remote region of Africa."—Alan Walker, Pennsylvania State University"This carefully planned and creatively crafted book is a record of a previously little-known niche of Africa's past. It recounts the tale of more than three thousand fossils, including twenty hominid specimens representing the new ancestral species Ardipithecus kadabba and their location in space, time and environment. Together they paint a picture of Africa in the late Miocene, of five to six million years ago. It was a part of northeast Africa, the Middle Awash of Ethiopia, at a time when it was rent by volcanoes and rifting. From this tectonically ravaged past, one marvels at such beauteous byproducts as this book reveals. To do justice to Ethiopia's surprises needs an exceptional book. This volume is worthy of the challenge: it is a model of its kind and will be hard to surpass. Happily, this is the first great volume on such matters to be edited by two sons of Africa, Doctors Haile-Selassie and WoldeGabriel, with a cast of twenty-five contributors from eight countries."—Phillip V. Tobias, F.R.S., For.M.NAS, University of the Witwatersrand, Johannesburg
