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

"About four hundred million years ago earthquake activity and possibly major storms caused sudden movements of large quantities of muddy sediment along the seafloor. Animal communities in the path of these sediment-laden flows were instantly engulfed, the inhabitants "frozen" in the last moment of their lives. Amazingly, many of the creatures lost in this ancient catastrophe were almost perfectly preserved through the eons, fossilized in a thick series of muds now known as the Hunsrück Slate west of the Rhine Valley in western Germany. Excavations there have yielded the most diverse and surpassingly beautiful collection of marine fossils of the Devonian period ever discovered. This book pays tribute to the exquisite fossils of the Hunsrück Slate. Large full-color photographic plates display fossil sponges, brachiopods, clams, starfish, sea lilies, trilobites, worms, sea spiders, sea stars, crustaceans, corals, and many other species. An accessible commentary recounts the discovery of the fossils and explains how the slate was formed, how the animals are preserved, the significance of the fossils, and the controversies that surround them. A special presentation in every way, this book makes an exceptional contribution to the fascinating history of life on Earth"--Provided by publisher.

This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became co

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later. Michael J. Everhart vividly captures the history of these startling finds over the decades and re-creates in unforgettable detail these animals from our distant past and the world in which they lived--above, within, and on the shores of America's ancient inland sea.
