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.

The plesiosaurus had a long, slender neck that it used to sneak up on prey. The ichthyosaurus was a strange cross between a dolphin and a crocodile. Learn about these amazing creatures as you experience what the dinosaur age was like from the bottom on the ocean. Illustrations on every page bring these creatures to life in all their razor-sharp, long-necked, spiny, scaly glory.

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

Dive into prehistoric waters and discover extraordinary sea monsters who reigned the ocean for 150 million years Ancient Sea Reptiles: Plesiosaurs, Ichthyosaurs, Mosasaurs, and More examines the anatomy, behavior, diversity, lifestyle, and evolutionary rise of creatures who conquered the seas for 150 million years during the Mesozoic era. Expert paleontologist Darren Naish puts these fearsome and mighty creatures under the microscope and transports readers to wild and primeval waters. In this gorgeously illustrated book, amazing creatures leap off the page, including: Mosasaurs, known as “T-Rexes of the deep" Cretaceous sea snakes Long-necked plesiosaurs Crocodile-like thalattosuchians, the earliest sea turtles Ancient Sea Reptiles features fossil photography and artistic reconstructions of ancient creatures, from evolutionary anomalies to apex predators who survived extinction events, with chapters that include: Chapter 1: Introduction Chapter 2: Evolution Chapter 3: Form and Function Chapter 4: Invading the Mesozic Oceans Chapter 5: Shark-Shaped Reptiles: The Ichthyosaurs Chapter 6: Long Necks, Big Mouths: Plesiosaurs and Their Kin Chapter 7: Sea Crocs: The Thalattosuchians Chapter 8: Mosasaurs: The Great Lizard Lizards Chapter 9: Sea Turtles Chapter 10: After the Mesozoic More than 80 percent of the world’s vast ocean is unmapped and unobserved, prompting the imagination to run wild on what might lurk in its depths. But Ancient Sea Reptiles proves that what stirs the imagination even more are the spectacular prehistoric creatures that have already been discovered. The book is a feast for the eyes and the scientific mind.
