Describes the age after the dinosaurs where huge beasts, reptiles, and flying creatures terrorized the earth.

In the days when dinosaurs dominated the earth, their marine counterparts - every bit as big and ferocious - reigned supreme in prehistoric seas. In this book, Richard Ellis takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. fierce predators, speculates on their habits, and tells how they eventually became extinct - or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs and mosasaurs who swam the ancient oceans - and who may, according to some, still frequent the likes of Loch Ness. animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to a giant snake threaded through the body of a turtle. At a length of nearly 60 feet, Mosasaurus hoffmanni boasted powerful jaws that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long - more than twice that of Tyrannosaurus rex - with teeth to match. reconstruct their lives and habitats. Their fossils have been found all over the world - in Europe, Australia, Japan and even Kansas - in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries and competing theories that compose the world of vertebrate paleontology. The text is also accompanied by Ellis' own illustrations of how these creatures probably appeared and, through these likenesses, we are invited to speculate on their locomotion, their predatory habits and their lifestyles.

A companion volume to the 3-D "Sea Monsters" film reveals the terrifying predators that lurked in the underwater Cretaceous world, in a volume that also profiles the scientists who study these ancient monsters and the technology that made the film possible.

“Excellent . . . Those who are interested in vertebrate paleontology or in the scientific history of the American midwest should really get a copy.” —PalArch’s Journal of Vertebrate Paleontology 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. “Oceans of Kansas remains the best and only book of its type currently available. Everhart’s treatment of extinct marine reptiles synthesizes source materials far more readably than any other recent, nontechnical book-length study of the subject.” —Copeia “[The book] will be most useful to fossil collectors working in the local region and to historians of vertebrate paleontology . . . Recommended.” —Choice

Dinosaurs are usually pictured in warm, tropical environments, but fossils found at the poles are filling in the gap of knowledge about how and where these creatures lived. Evidence from bones and teeth to trackways and skin impressions raises important questions: How did dinosaurs cope with three months of total darkness in winter? What plants grew in the polar regions? How cold was it? What are the implications for today, as glaciers retreat, ice shelves melt, and permafrost thaws? The polar regions are a unique "library" of the past, and Caroline Arnold introduces readers to the gigantic prehistoric creatures that inhabited them.

The ocean is filled with giant, strange, and scary creatures such as whales, octopuses, and sharks—but the prehistoric megalodon was powerful enough to crush a killer whale. Other sea beasts of the past could hold their own against even the most mysterious of modern sea creatures. Sea scorpions had claws the size of tennis rackets. Tanystropheus used its long neck to catch fish from land. And Leedsichthys had as many as 40,000 teeth! What would happen if these extinct beasts came to life? Imagine prehistoric sea beasts chasing dolphins, fighting crocodiles, and hunting humpback whales—and learn all about the prehistoric creatures of the deep!

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

Meet the incredible animals that have disappeared due to competition, mass extinctions, hunting, and human activity. Lost Animals brings back to life some of the most charismatic creatures to inhabit the planet. It captures the imagination with more than 200 incredible photographs, artworks of fossils, and scientific drawings of charming creatures like dodos, paraceratherium (the largest land mammal), spinosaurus (the biggest carnivorous dinosaur), placeoderm fishes (the sharks of their day), and more! Lost Animals is a captivating documentation of evolution and extinction. Each chapter focuses on a specific time in Earth's history, from the Cambrian explosion (the most intense surge of evolution the world has ever experienced) to present times, with profiles of the key species that lived then. From long extinct animals to Lazarus species--animals that were thought to be extinct before being rediscovered--this book takes readers on a journey through Earth's natural history, highlighting the world's biggest animal losses and its moments of conservational hope.
