Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Water Reptiles of the Past and Present It was just forty years ago that the writer of these lines, then an assistant of his beloved teacher, the late Professor B. F. Mudge, dug from the chalk rocks of the Great Plains his first specimens of water reptiles, mosasaurs and plesiosaurs. To the youthful collector, whose first glimpse of ancient vertebrate life had been the result of accident, these specimens opened up a new world and diverted the course of his life. They were rudely collected, after the way of those times, for modern methods were impracticable with the rifle in one hand and the pick in the other. Nor was much known in those days of these or other ancient creatures, for the science of vertebrate paleontology was yet very young. There were few students of fossil vertebrates - Leidy, Cope, and Marsh were the only ones in the United States - and but few collectors, of whom the writer alone survives. Those broken and incomplete specimens, now preserved in the museum of Yale University, will best explain why this little book was written. The author offers it, so far as lies within him, as an authoritative and accurate account of some of the creatures of earlier ages which sought new opportunities by going down from the land into the water. So far as possible he has endeavored to make the text understandable, and, he hopes, of interest also, to the non-scientific reader. He will not apologize for such scientific terms as remain, since only by their use can precision be attained: there are no common English equivalents for them. The reader will find their explanations in the chapter on the skeleton of reptiles, and especially in the illustrations. The author has had the opportunity during recent years of critically studying nearly all the reptiles described in the following pages, but, if that were the only source of his information, the accounts of many would have been meager. He has endeavored, briefly at least, to mention the names of all those to whom we are chiefly indebted for our knowledge, but in such a work as this it is manifestly impracticable to give due credit to every one.

Download or read book Dinosaurs and Other Mesozoic Reptiles of California written by Richard Hilton and published by Univ of California Press. This book was released on 2003-08-29 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ancient Marine Reptiles written by Jack M. Callaway and published by Academic Press. This book was released on 1997-03-12 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 2022-10-18 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: An authoritative illustrated guide to the mighty reptiles that dominated the seas of the Mesozoic for 185 million years New discoveries are revealing that many ancient oceangoing reptiles were energetic animals capable of inhabiting an array of watery habitats and climates, including polar winters. The Princeton Field Guide to Mesozoic Sea Reptiles provides the most up-to-date and comprehensive coverage of the great Mesozoic groups that commanded the seas for tens of millions of years. This incredible field guide covers 435 species and features stunning illustrations of swimming reptiles ranging in size from little lizards to others with great necks longer than their bodies. It discusses the history of sea reptiles through 185 million years of the Mesozoic, their anatomy, physiology, locomotion, reproduction and growth, and extinction, and even gives a taste of what it might be like to travel back to the Mesozoic. This one-of-a-kind guide also challenges the common image of these reptiles as giants of the prehistoric waters, showing how the largest weighed far less than today’s biggest whales. Features detailed species accounts of 435 different kinds of sea reptiles, with the latest size and mass estimates Written and illustrated by the acclaimed researcher and artist who helped to redefine our understanding of dinosaur anatomy Describes placodonts, plesiosaurs, ichthyosaurs, mosasaurs, sea snakes, sea turtles, marine crocs, and more Covers everything from biology to the colorful history of sea reptile paleontology Includes dozens of original skeletal drawings and full-color life scenes
