Exceptional Fossil Preservation: A Unique View on the Evolution of Marine Life (The Critical Moments and Perspectives in Earth History and Paleobiology) - Tapa blanda

Reading Exceptional Fossil Preservations is like a refreshing slap in the face...I found myself paging through this book, thinking, 'Wow. What other cool stuff is in here?' -- David Kendrick American Paleontologist An inordinate amount of what we know about the fossil record comes from a handful of spectacular fossil sites... Each of these deposits has a unique story to tell, and this volume is here to tell them... Recommend[ed] to any serious student of paleontology who wishes to know more about a dozen and a half of the most spectacular fossil sites worldwide. -- Lynne M. Clos Fossil News Exceptional Fossil Preservation provides the reader with the opportunity to see and read about exceptional fossils that normally appear only in professional journals. Jack's Stacks Will do much to encourage more fieldwork by scientists and amateur fossil hunters. Exceptionally well-referenced to the technical literature. An essential reading and browsing book for all who have an interest in this fascinating subject. An exceptionally fine book. Northeastern Naturalist

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 Lagerstatten, 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 Lagerstatten sites and to paleobiology in general. This volume describes many of the most famous Lagerstatten 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 Lagerstatten 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.
