Book Description
Fossils from fluvial deposits of early Oligocene age in Egypt document the earliest known diverse avifauna from Africa, comprising at least 13 families and 18 species. Included are the oldest fossil records of the Musophagidae (turacos), Pandionidae (ospreys), Jacanidae (jacanas), and Balaenicipitidae (shoebilled storks). Other families represented are the Accipitridae (hawks and eagles), Rallidae (rails), Gruidae (cranes), Phoenicopteridae (flamingos), Ardeidae (herons), Ciconiidae (storks), and Phalacrocoracidae (cormorants). A highly distinctive rostrum is described as a new family, Xenerodiopidae, probably most closely related to herons. A humerus lacking the distal end is tentatively referred to the same family. Two new genera and three species of large to very large jacanas are described from the distal ends of tarsometatarsi. This Oligocene avifauna resembles that of modern tropical African assemblages. The habitat preferences of the constituent species of birds indicate a tropical, swampy, vegetation-choked, fresh-water environment at the time of deposition.

Book Description
This second, completely revised edition of “Paleogene fossil birds” gives a comprehensive, updated overview of the avian fossil record from a geological period that lasted from the end-Cretaceous mass extinction event (66 million years ago) to the end of the Oligocene epoch (23 mya). Paleogene avifaunas are highly diversified and not only feature unusual archaic groups without close living relatives but also offer unique insights into the evolution and biogeographic history of extant birds. The main body of the book constitutes an in-depth survey of the known diversity of Paleogene avifaunas. The reader is introduced into basic skeletal features of extinct avian taxa, with these fossil forms being placed into a phylogenetic context in the light of current hypotheses on the interrelationships of extant birds. The geographical and temporal occurrences of the various fossil groups are outlined and their evolutionary significance is discussed. Concluding sections inform more general aspects of Paleogene avifaunas, such as possible causes of major faunal changes. In addition to being a reference work for the early evolution of modern birds from a paleornithological perspective, the present work also enables researchers in other fields of vertebrate paleontology to gain an improved understanding of Paleogene ecosystems. Numerous color photos of representative specimens furthermore make the new edition attractive to a wider audience interested in the avian fossil record.

Book Description
Biology of Marine Birds provides the only complete summary of information about marine birds ever published. It analyzes their breeding biology, ecology, taxonomy, evolution, fossil history, physiology, energetics, and conservation. The book covers four orders of marine birds in detail and includes two summary chapters that address the biology of shorebirds and wading birds and their lives in the marine environment. Summary tables give detailed information on various aspects of their life histories, breeding biology, physiology and energetics, and demography. It provides a guide to ornithologists and students for research projects.

Book Description
The Phanerozoic Geology and Natural Resources of Egypt includes a series of chapters written by highly qualified group of researchers whose expertise is recognized and appreciated not only in Egypt, but also in the world over. The chapters span a wide range of geological subdisciplines including tectonics, paleogeography, stratigraphy, sedimentology, paleontology, groundwater, and energy resources, just to name a few. In this regard, the book provides the reader with ample knowledge about the different facets of the fascinating and always intriguing geology of Egypt since the Precambrian time. For a junior researcher or a geoscience student, the book is a comprehensive, multidisciplinary one-stop resource that they will continue to reference and rely on for years to come. For a more experienced scientist, the book summarizes the current state of knowledge, highlights the magnitude of complexity of the geology of Egypt and northeast Africa, and reveals potential areas where future research should be directed. The book is written in simple, easy to understand English language and contains very useful high-quality illustrations. Last but not least, The Phanerozoic Geology and Natural Resources of Egypt has been reviewed and edited by world class, highly ranked geoscientists from Egypt, Europe, and USA.

Book Description
For nearly a half century, Dr. Simons has dominated the study of primate evolution. This volume summarizes the current state of knowledge in many aspects of primate and human evolution that have been studied by Simons and his colleagues and place it in a broader paleontological and historical perspective. The book contains the results of new research as well as reviews of many of the critical issues in primate and human evolution during the last half of the twentieth century.

Book Description
Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

Book Description
The transition from the Eocene to the Oligocene epochs was the most significant event in earth history since the extinction of dinosaurs. As the first Antarctic ice sheets appeared, major extinctions and faunal turnovers took place on the land and in the sea, eliminating forms adapted to a tropical world and replacing them with the ancestors of most of our modern animal and plant life. Through a detailed study of climatic conditions and of organisms buried in Eocene-Oligocene sediments, this volume shows that the separation of Antarctica from Australia was a critical factor in changing oceanic circulation and ultimately world climate. In this book forty-eight leading scientists examine the full range of Eocene and Oligocene phenomena. Their articles cover nearly every major group of organisms in the ocean and on land and include evidence from paleontology, stable isotopes, sedimentology, seismology, and computer climatic modeling. The volume concludes with an update of the geochronologic framework of the late Paleogene. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
