Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Fossil mammals and birds have been found at many localities in Britain, and there is a long history of collection and study, dating back to the earliest days of palaeontology. This volume of the GCR Series contains a description of around 30 representative sites, selected for the Mesozoic-Tertiary part of the history of these vertebrates.

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.

An exploration of all that is known about the origin of birds and of avian flight. It draws on fossil evidence and studies of the structure and biochemistry of living birds to present knowledge and data on avian evolution and to propose a new model of this evolutionary process.

Living Dinosaurs offers a snapshot of our current understanding of the origin and evolution of birds. After slumbering for more than a century, avian palaeontology has been awakened by startling new discoveries on almost every continent. Controversies about whether dinosaurs had real feathers or whether birds were related to dinosaurs have been swept away and replaced by new and more difficult questions: How old is the avian lineage? How did birds learn to fly? Which birds survived the great extinction that ended the Mesozoic Era and how did the avian genome evolve? Answers to these questions may help us understand how the different kinds of living birds are related to one another and how they evolved into their current niches. More importantly, they may help us understand what we need to do to help them survive the dramatic impacts of human activity on the planet.

In 1861, paleontologists unearthed a dinosaur fossil that looked like a bird! Archaeopteryx, as this species is known today, was a link between ancient dinosaurs and modern birds. In this guide, based on fundamental elementary science concepts, readers view amazing bird fossils and learn how they formed. Readers also learn how scientists know birds are descended from dinosaurs by comparing traits from both. Amazing photographs are paired with accessible text to make this book both educational and fun. Sidebars provide additional chances to dazzle young readers.

Scientists have recovered more than a billion fossils, but no discovery has been more breath-taking than the fossils recently found in northern China, findings which prove that several families of dinosaurs had feathers, or feathery hair-like coverings, adorning their bodies. Now in the beautifully designed Feathered Dinosaurs, paleontologist John Long and illustrator Peter Schouten provide a stunning visual record of these extraordinary prehistoric creatures, illuminating the evolutionary march from primitive, feathered dinosaurs through to the first true flying birds. Schouten, an acclaimed natural history artist, has created 80 full-color paintings that capture the striking physical traits of these feathered dinosaurs. Drawing on his extensive knowledge of the lifestyles of modern birds and mammals, plus the extant scientific data regarding how these dinosaurs might have looked and behaved, Schouten has produced not only the most beautiful but also the most accurate visual representations of these animals in print. Equally important, John Long, a noted paleontologist and widely published science author (with some 24 books to his credit), provides an engaging companion text that places these feathered dinosaurs within the larger family of dinosaurs--for instance, outlining their relationship to T. Rex and Velociraptor, species well known to Jurassic Park fans--and discusses the factual information that can be deduced from their fossil remains, in effect providing an insightful natural history of this remarkable group. A true marriage of art and science, Feathered Dinosaurs presents an unprecedented visual record of one of the most significant breakthroughs in the history of vertebrate paleontology--the discovery that many predatory dinosaurs were cloaked with feathers, perhaps just as colorful and fanciful as those of their living relatives.
