Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages that have become sea creatures (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and other). Mos t o f these marine reptiles, often wrongly called 'dinosaurs' are extinct. (This 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 i n t he ocean. Key features: 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 illu str at ed.
