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.

Excerpt: Species: Eremopezus is a prehistoric bird genus. It is known only from the fossil remains of a single species, the huge and presumably flightless Eremopezus eocaenus. This was found in Upper Eocene Jebel Qatrani Formation deposits around the Qasr el-Sagha escarpment, north of the Birket Qarun lake near Faiyum in Egypt. The rocks its fossils occur in were deposited in the Priabonian, with the oldest dating back to about 36 million years ago (Ma) and the youngest not less than about 33 Ma. It is not precisely known from which strata the first few remains of this bird were collected. They were formerly considered of Early Oligocene age-some 33-30 Ma-but this is now assumed incorrect, as only the upper and not the entire Jebel Qatrani Formation is of Oligocene age. It is also possible that they are from the slightly older...

Book Description
Carbonate sediments are of increasing relevance for archives of past environmental conditions and for economical reasons in areas of geothermal energy and hydrocarbon reservoirs. Complex interaction of physical and chemical parameters with biological parameters determines the architecture and composition of carbonate sedimentary bodies. This book closes some of the still existing gaps in our understanding of the influence and interplay of physical, chemical, and biological parameters with carbonate sedimentation. An understanding of this interaction is not only required for reliable prediction of reservoir quality but also for a robust interpretation of environmental conditions in the past and the present. It is written by geologists for geologists in order to provide an easily accessible overview of the large amount of relevant information provided by the neighbouring sciences. The approach of the book is to document the modern depositional environments of three classical areas of carbonate deposition, each characteristic for a specific sedimentological setting (isolated platform, attached shelf, ramp) in order to assess both the range of physical, biological and chemical parameters and their sedimentary response. This book presents a comprehensive compilation based on data from published work and unpublished theses, and the integration of these data in order to extract previously undiscovered relationships between the discussed parameters and carbonate deposition.

Book Description
Unearthing the amazing hidden stories of women who changed paleontology forever. For centuries, women have played key roles in defining and developing the field of vertebrate paleontology. Yet very little is known about these important paleontologists, and the true impacts of their contributions have remained obscure. In Rebels, Scholars, Explorers, Annalisa Berta and Susan Turner celebrate the history of women "bone hunters," delving into their fascinating lives and work. At the same time, they explore how the discipline has shaped our understanding of the history of life on Earth. Berta and Turner begin by presenting readers with a review of the emergence of vertebrate paleontology as a science, emphasizing the contributions of women to research topics and employment. This is followed by brief biographical sketches and explanations of early discoveries by women around the world over the past 200 years, including those who who held roles as researchers, educators, curators, artists, and preparators. Forging new territory, Berta and Turner highlight the barriers and challenges faced by women paleontologists, describing how some managed to overcome those obstacles in order to build careers in the field. Finally, drawing on interviews with a diverse group of contemporary paleontologists, who share their experiences and offer recommendations to aspiring fossil hunters, they provide perspectives on what work still needs to be done in order to ensure that women's contributions to the field are encouraged and celebrated. Uncovering and relating lost stories about the pivotal contributions of women in vertebrate paleontology doesn't just make for enthralling storytelling, but also helps ensure a richer and more diverse future for this vibrant field. Illuminating the discoveries, collections, and studies of fossil vertebrates conducted by women in vertebrate paleontology, Rebels, Scholars, Explorers will be on every paleontologist's most-wanted list and should find a broader audience in the burgeoning sector of readers from all backgrounds eager to learn about women in the sciences.

Book Description
The consummate guide to the ultimate sabertooth. Few animals spark the imagination as much as the sabertooth cat Smilodon. With their incredibly long canines, which hung like fangs past their jaws, these ferocious predators were first encountered by humans when our species entered the Americas. We can only imagine what ice age humans felt when they were confronted by a wild cat larger than a Siberian tiger. Because Smilodon skeletons are perennial favorites with museum visitors, researchers have devoted themselves to learning as much as possible about the lives of these massive cats. This volume, edited by celebrated academics, brings together a team of experts to provide a comprehensive and contemporary view of all that is known about Smilodon. The result is a detailed scientific work that will be invaluable to paleontologists, mammalogists, and serious amateur sabertooth devotees. The book • covers all major aspects of the animal's natural history, evolution, phylogenetic relationships, anatomy, biomechanics, and ecology • traces all three Smilodon species across both North and South America • brings together original, unpublished research with historical accounts of Smilodon's discovery in nineteenth-century Brazil The definitive reference on these iconic Pleistocene mammals, Smilodon will be cited by researchers for decades to come.

Book Description
This book is designed as a source and reference for people interested in the history and fossil record of North American tertiary mammals. Each chapter covers a different family or order, and includes information on anatomical features, systematics, the distribution of the genera and species at different fossil localities, and a discussion of their paleobiology. Many of these groups have never been covered in this fashion before.
