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
In the Mesozoic Era, while dinosaurs roamed on land, giant carnivorous reptiles ruled the seas. These enormous underwater creatures have enthralled the public imagination since Mary Anning discovered spectacular reptile skeletons on Dorset's 'Jurassic Coast' in the early 1800s. Join palaeontologist Darren Naish on a tour of these incredible animals, ranging from shark-shaped ichthyosaurs and long-necked plesiosaurs to gigantic, predatory mosasaurs. Occupying roles similar to those of modern sharks, seals and whales, they filled the ancient oceans for a period of 180 million years. Naish charts the evolutionary rise of the ancient sea reptiles and their domination of the Mesozoic Seas. He reveals how these reptiles moved in water, the anatomical advantages of their soft tissue, skin and blubber, how their jaws were specialized for aquatic prey, and the sensory organs that enabled them to see, smell or hear underwater. Later chapters focus on each of the major lineages: the shark-shaped ichthyosaurs, the long-necked plesiosaurs; the crocodilelike thalattosuchians, the fast-swimming mosasaurs, and the first sea turtles. The book is richly illustrated with photographs of striking specimens and artistic reconstructions which bring these giants of the sea to life.

Book Description
This is a detailed study of the Plesiosaurs, a group of giant, long-necked marine reptiles that belong to the order Plesiosauria. These animals emerged in the Late Triassic period and became especially predominant during the Jurassic period.

Book Description
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.

Book Description
Excerpt from Water Reptiles of the Past and Present In many respects the internal structure of the amphibians of the present time is widely different from that of reptiles, though there can be no doubt that the early amphibian ancestors of the modern toads, frogs, and salamanders were also the ancestors of all living and extinct reptiles, and it is a fact that the living amphib ians differ more from some of the ancient ones than those early amphibians did from their contemporary reptiles. Discoveries in recent years have bridged over nearly all the essential differ ences between the two classes so completely that many forms can not be classified unless one has their nearly complete skeletons. We know that some of the oldest amphibians, belonging to the great division called Stegocephalia, were really water-breathers during a part of their lives, because distinct impressions of their branchiae, or water-breathing organs, have been discovered in the rocks with their skeletal remains, but we are not at all sure that some of the more highly developed kinds were not air-breathers from the time they left the egg; indeed, we rather suspect that such was the case. We are also now quite certain that, from some of the early extinct reptiles - the immediate forbears probably of the great dinosaurs - the class of birds arose, since the structural relation ships between birds and reptiles are almost as close as those between reptiles and amphibians.

Book Description
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
