Mr. Gould is an exceptional combination of scientist and science writer. . . . He is thus exceptionally well placed to tell these stories, and he tells them with fervor and intelligence."—James Gleick, New York Times Book Review High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

Book excerpt: Since its discovery in 1909 by Charles Doolittle Walcott, then Secretary of the Smithsonian Institution, the Burgess Shale in the Canadian Rocky Mountains has fascinated both scientists and the public with its plethora of weird wonders - life forms of the past so unfamiliar they cannot easily be assigned to known taxonomic groups. This century's most significant invertebrate fossil discovery, the Burgess Shale provides an unprecedented window into the explosive evolution during the Cambrian period that began about 540 million years ago, one of the most enigmatic episodes in the history of life. This book provides the first comprehensive set of illustrations of the extraordinary life forms revealed in the Burgess Shale. In addition to the more common fossilized hard skeletons, the Burgess Shale preserved the soft parts of these organisms, which provide a key to understanding the early evolution of the major groups of animals that inhabit the earth today. The Fossils of the Burgess Shale shows much remarkable detail - including digestive tracts and other internal organs - of creatures preserved in particles of mud fine enough to penetrate every crack and unevenness. The book begins with the history of exploration and research in the Burgess Shale, the geologic setting and preservation of the fossils, and a discussion of the Cambrian radiation, the period when almost all the major phyla of animals evolved. These introductory chapters are followed by 199 high-quality photographs and line drawings with detailed species accounts that describe important features of each specimen, as well as the ecology and taxonomy of each group. A complete list of all currently accepted species described from the Burgess Shale and a comprehensive bibliography follow the illustrations. The Fossil of the Burgess Shale is a compendium of fascinating Cambrian treasures that offer a rare glimpse into the nature of early life on our planet. They have figured prominently in recent evolutionary debates. The National Museum of Natural History, which houses more than 65,000 fossils collected by Walcott from the Burgess Shale, will open a new exhibition of the specimens in 1995.

Available in PDF, EPUB and Kindle. Book excerpt: Most nonscientists are usually aware of fossils, and it is commonly believed that they are extremely rare. In fact, fossils are exceptionally common in many sedimentary rocks and are used extensively in geology for age dating, interpretation of ancient environments, and the discovery of natural resources. However, there is another type of fossil deposit that is truly rare. These rare fossil deposits, called Lagerstätten, preserve the remains of the soft tissues or the articulated skeletal remains of ancient creatures in truly astonishing fine detail. Some of these deposits are world-famous, such as the Burgess Shale, or Solnhofen but there are others dating from many different geological eras from the Paleozoic, up to the Eocene. Recently, a concerted effort has been made to understand the overall significance of these rare fossil deposits. Whereas in the past these deposits were considered novelties, modern researchers are trying to understand what they can tell us about ancient life and environments. New sophisticated techniques (including image and geochemical analyses) are providing enormous new contributions to our knowledge of Lagerstätten sites and to paleobiology in general. This volume describes many of the most famous Lagerstätten locations worldwide and is complete with over 70 superb halftones showing some of these exotic fossils in all their glory. Paleontologists are beginning to understand why such deposits occur, how they have varied since the advent of marine metazoan life, and how their presence effects our understanding of the evolution of life in the Earth's oceans. In this way, the study of Lagerstätten continues to move towards the mainstream of paleobiological, biological, and geological research, and away from its former status as the examination of mere curiosities. All those interested in these beautiful and sometimes enigmatic deposits will want to own this book.

Download or read book The Ecology of the Cambrian Radiation written by Robert Riding and published by Columbia University Press. This book was released on 2001 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambrian radiation was the explosive evolution of marine life that started 550,000,000 years ago. It ranks as one of the most important episodes in Earth history. This key event in the history of life on our planet changed the marine biosphere and its sedimentary environment forever, requiring a complex interplay of wide-ranging biologic and nonbiologic processes. The Ecology of the Cambrian Radiation offers a comprehensive and surprising picture of the Earth at that ancient time. The book contains contributions from thirty-three authors hailing from ten countries and will be of interest to paleontologists, geologists, biologists, and other researchers interested in the global Earth-life system.

Download or read book Fossil Ecosystems of North America written by Paul Selden and published by CRC Press. This book was released on 2008-03-20 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most major recent advances in understanding the history of life on Earth have been through the study of exceptionally well preserved biotas (Fossil-Lagerstätten). These are windows on the history of life on Earth and can provide a fairly complete picture of the evolution of ecosystems through time. This book follows the success of Evolution of Fossil Ecosystems by the same authors which covered Fossil-Lagerstätten around the world. The success of the first book prompted this new book which draws on four localities from the original book and adds another ten, all located in North America. Following an introduction to Fossil-Lagerstätten, each chapter deals with a single fossil locality. Each chapter contains a brief introduction placing the Lagerstätte in an evolutionary context; there then follows a history of study of the locality; the background sedimentology, stratigraphy and palaeoenvironment; a description of the biota; discussion of the palaeoecology, and a comparison with other Lagerstätten of a similar age and/or environment. At the end of the book is an Appendix listing museums in which to see exhibitions of fossils from each locality and suggestions for visiting the sites.
