Book Description
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.

Book Description
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.

Book Description
Taphonomy: A Process Approach is the first book to review the entire field of taphonomy, or the science of fossil preservation. It describes the formation of animal and plant fossils in marine and terrestrial settings and how this affects deciphering the ecology and extinction of past lifeforms and the environments in which they lived. The volume emphasises a process approach to taphonomy and reviews the taphonomic behaviour of all important taxa, plant and animal. It will be useful to anyone interested in the preservation of fossils and the formation of fossil assemblages, but it is aimed primarily at advanced students and professionals working in paleontology, stratigraphy, sedimentology, climate modeling and biogeochemistry.

Book Description
If one does not understand the biology of the coral reef, one does not understand the reef at all. So, using more than 250 illustrations and specially drawn ecological reconstructions of reef communities, Rachel Wood provides a unique evolutionary approach to the understanding of ancient coral reef ecosystems. Marine organisms have aggregated to form reefs for over 3.5 billion years--creating the largest biologically constructed feature on earth, some visible from space. However, their study has been largely descriptive. Reef Evolution, documents the fundamental biological processes and innovations which have molded the evolution of reef ecosystems and given rise to the highly complex communities found today. The appearance of clonality, the acquisition of photosymbiosis, and the radiation of predator groups are all discussed in depth. Data from the fossil record documents the evolutionary development of reef ecosystems. Although reefs only occupy a small percentage of the oceans, their importance to the marine environment is many-faceted and global. They create harbors and allow the development of shallow basins with associated mangrove or seagrass communities; they protect coastlines from erosion; are involved in the regulation of atmospheric carbon, which in turn contributes to climate control. can provide extensive oil and gas reservoirs. From a biological standpoint, however, the great significance of reefs lies in their ability to generate and maintain a substantial proportion of tropical marine biodiversity. This unique interdisciplinary approach provides students and researchers in evolution, marine biology, ecology, paleontology, biodiversity, and geology with a text that will allow them to truly understand the biological innovations which have molded the evolution of coral reefs and given rise to the highly complex communities found today.

Book Description
Over the past decade, fossil finds from China have stunned the world, grabbing headlines and changing perceptions with a wealth of new discoveries. Many of these finds were first announced to English speakers in the journal Nature.Rise of the Dragon gathers together sixteen of these original reports, some augmented with commentaries originally published in Nature's "News and Views" section. Perhaps the best known of these new Chinese fossils are the famous feathered dinosaurs from Liaoning Province, which may help end one of the most intense debates in paleontology—whether birds evolved from dinosaurs. But other finds have been just as spectacular, such as the minutely preserved (to the cellular level) animal embryos of the 670 million-year-old Duoshantuo phosphorites, or the world's oldest known fish, from the Chengjiang formation in southwestern Yunnan Province. Rise of the Dragon makes descriptions and detailed discussions of these important finds available in one convenient volume for paleontologists and serious fossil fans.
