Ancient Marine Reptiles by Jack M. Callaway


Original Title: Ancient Marine Reptiles

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. 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 illustrated

Evolution by Donald R. Prothero


Original Title: Evolution

Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before. The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process. Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

The Complete Idiot S Guide To The Oceans by Joe Kraynak


Original Title: The Complete Idiot S Guide To The Oceans

Although our oceans are some of the most beautiful and diverse environments in the world, most people know very little about the ocean's ecology or just how much humans depend on the oceans for survival. The Complete Idiot's Guide' to the Oceans will be a marine-lover's reference for mapping the world's oceans and their exploration. Authors will provide key illustrations to help readers understand important concepts along the way with a color photo insert presenting a wide array of marine creatures and habitats.

At The Water S Edge by Carl Zimmer


Original Title: At The Water S Edge

Everybody Out of the Pond At the Water's Edge will change the way you think about your place in the world. The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

Deep Alberta by John Acorn


Original Title: Deep Alberta

Alberta is well known for its fossil treasures, and author John Acorn is as keen on the long-dead creatures of Alberta as he is on the living. Here, John features 80 of the most noteworthy fossils, fossil locations, and fossil hunters from this most palaeontological of provinces. There's more to the story of "deep Alberta" than dinosaurs, but dinosaur fans will find all their favourite beasts here as well -- from Edmontosaurus to Tyrannosaurus rex, and everything in-between. Then there are the surprises, such as the world's oldest pike, the discovery of a venomous mammal, and the fossils found in such unlikely places as Edmonton and Calgary. Prepared with the collaboration of palaeontologists around Alberta, and the world-renowned Royal Tyrrell Museum, this is a book that is long overdue, and that deserves a place on everyone's bookshelf.
