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

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
In the days when dinosaurs dominated the earth, their marine counterparts - every bit as big and ferocious - reigned supreme in prehistoric seas. In this book, Richard Ellis takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. fierce predators, speculates on their habits, and tells how they eventually became extinct - or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs and mosasaurs who swam the ancient oceans - and who may, according to some, still frequent the likes of Loch Ness. animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to a giant snake threaded through the body of a turtle. At a length of nearly 60 feet, Mosasaurus hoffmanni boasted powerful jaws that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long - more than twice that of Tyrannosaurus rex - with teeth to match. reconstruct their lives and habitats. Their fossils have been found all over the world - in Europe, Australia, Japan and even Kansas - in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries and competing theories that compose the world of vertebrate paleontology. The text is also accompanied by Ellis' own illustrations of how these creatures probably appeared and, through these likenesses, we are invited to speculate on their locomotion, their predatory habits and their lifestyles.

Book Description
Using a series of case studies, the book demonstrates the power of dynamic analysis as applied to the fossil record. Written in an engaging and informative style, Dynamic Paleontology outlines the best application of quantitative and other tools to critical problems in the paleontological sciences including such topics as analysis of the Cambrian Explosion and the question regarding the presence of life on Mars. The book considers how we think about certain types questions and shows how we can refine our approach to analysis right from the beginning of any particular research effort. The analytical tools presented here will have wide application to other fields of knowledge; as such the book represents a major contribution to our deployment of modern scientific method.
