Book Description
The defining masterwork on the evolution of reptiles. Over 300 million years ago, an early land vertebrate developed an egg that contained the embryo in an amnion, allowing it to be deposited on land. This moment marked the first step in the fascinating and complex evolutionary journey of the reptiles. In The Rise of Reptiles, paleontologist Hans-Dieter Sues explores the diversity of reptilian lineages, discussing the relationships among turtles, crocodylians, lizards and snakes, and many extinct groups. Reflecting the tremendous advances in the study of reptilian diversity and phylogeny over recent decades, this book is the first detailed, contemporary synthesis of the evolutionary history of these remarkable animals. Reptiles have always confused taxonomists, who have endlessly debated and rewritten their classifications. In this book, Sues adopts an explicitly phylogenetic framework to sift through the evidence and discuss the origin and diversification of Reptilia in a way no one has before. He also examines the genealogical link between dinosaurs and birds and sheds new light on the Age of Reptiles, a period that saw the rise and fall of most dinosaurs. With this single meticulously researched volume, Sues paints a complete portrait of reptilian evolution. Numerous photographs of key specimens from around the world introduce readers to the reptilian fossil record, and color images of present-day reptiles illustrate their diversity. The extensive bibliography provides an invaluable guide for readers who are interested in exploring individual topics more deeply. Accurate, synthetic, and sweeping, The Rise of Reptiles is the definitive work on the subject.

Book Description
One of the most geologically complex and diverse states, California spent much of the age of dinosaurs under water. While most of the fossils found in the state are those of reptiles that lived in the sea (thalattosaurs, ichthyosaurs, mosasaurs, plesiosaurs, and turtles), some are those of birds and pterosaurs that soared above it. Other fossils come from terrestrial animals that died and were washed into the ocean. These include turtles, crocodiles, lizards, and dinosaurs such as armored ankylosaurs, duck-billed hadrosaurs, and a variety of carnivorous dinosaurs. Richard Hilton is the first to tell the unsung story of the dinosaurs and reptiles of land, sea, and sky that lived in California and Baja California during the Mesozoic era (245 million-65 million years ago), in addition to the history of their discovery. Vibrantly illustrated with more than three hundred photographs, paintings, and drawings, this book provides geological and environmental details, describes the significance of the major fossils, and chronicles the adventures involved in the discovery, preparation, and publishing of the finds. Hilton also includes accounts of the scientists, teachers, students, ranchers, and weekend fossil hunters who endured (and continue to endure) harsh weather, fires, wild animals, and the usual challenges of fieldwork to collect fossil remains and make major discoveries. These enthusiasts managed to safeguard an abundance of fossil resources, some of which would otherwise have been destroyed by quarrying, paving, and housing developments. Dinosaurs and Other Mesozoic Reptiles of California takes this legacy one step further by documenting information about the fossils and their finders in accessible prose and vivid artistic renderings, creating a valuable contribution to our understanding of California’s prehistoric past.

Book Description
Vertebrate evolution has led to the convergent appearance of many groups of originally terrestrial animals that now live in the sea. Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and others) that have become sea creatures. Most of these marine reptiles, often wrongly called "dinosaurs", are extinct. This edited book is devoted to these extinct groups of marine reptiles. These reptilian analogs represent useful models of the myriad adaptations that permit tetrapods to live in the ocean. - First book in more than 80 years devoted exclusively to fossil marine reptiles - Documents the most current research on extinct marine reptiles - Prepared by the world's most prominent experts in the field - Well illustrated
