Containing papers by leading authorities on several of the major extinction events of the geological record, this volume brings together new data on a wide range of floral and fuanal groups. Several of the papers describe the recovery and recolonization processes following the extinction events while others discuss the problems of survivor taxa, disaster taxa and progenitor species. The examples chosen come from geological successions in North America, South America, Europe, Asia and the Indian subcontinent. The text is aimed at palaeontologists, palaeobiologists, sedimentary geologists and all those involved in the debate over the cause and nature of extinction events.

The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

This book examines the arguments and behavior of the scientists who have been locked in conflict over two competing theories to explain why, 65 million years ago, most life on earth—including the dinosaurs—perished.

The first book to review all the evidence concerning both the dinosaur extinctions and all the other major extinctions - of plant, animal, terrestrial, and marine life - in the history of life. All the extinction mechanisms are critically assessed, including meteorite impact, anoxia, and volcanism. - ;Why do mass extinctions occur? The demise of the dinosaurs has been discussed exhaustively, but has never been out into the context of other extinction events. This is the first systematic review of the mass extinctions of all organisms, plant and animal, terrestrial and marine, that have occurred in the history of life. This includes the major crisis 250 million years ago which nearly wiped out all life on Earth. By examining current paleontological, geological, and sedimentological evidence of environmental changes, the cases for explanations based on climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions are all critically evaluated. -

Fiction and the Sixth Mass Extinction is one of the first works to focus specifically on fiction's engagements with human driven extinction. Drawing together a diverse group of scholars and approaches, this volume pairs established voices in the field with emerging scholars and traditionally recognized climate fiction ('cli-fi') with texts and media typically not associated with Anthropocene fictions. The result is a volume that both engages with and furthers existing work on Anthropocene fiction as well as laying groundwork for the budding subfield of extinction fiction. This volume takes up the collective insistence on the centrality of story to extinction studies. In various and disparate ways, each chapter engages with the stories we tell about extinction, about the extinction of animal and plant life, and about the extinction of human life itself. Answering the call to action of extinction studies, these chapters explore what kinds of humanity caused this event and what kinds may live through it; what cultural assumptions and values led to this event and which ones could lead out of it; what relationships between human life and this planet allowed the sixth mass extinction and what alternative relationships could be possible.

This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. The most famous is the mass extinction that happened about 65 million years ago, and that caused the death of the dinosaurs. But that was not the worst mass extinction: that honour goes to the extinction at the end of the Permian Period, about 250 million years ago, when over 90% of life is thought to have become extinct. What caused these catastrophes? Was it the effects of a massive meteorite impact? There is evidence for such an impact about 65 million years ago. Or was it a period of massive volcanic activity? There is evidence in the rocks of huge lava flows at periods that match several of the mass extinctions. Was it something to do with climate change and sea level? Or was it a combination of some or all of these? The question has been haunting geologists for a number of years, and it forms one of the most exciting areas of research in geology today. In this book, Tony Hallam, a distinguished geologist and writer, looks at all the different theories and also what the study of mass extinctions might tell us about the future. If climate change is a key factor, we may well, as some scientists have suggested, be in a period of mass extinction of our own making.

The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea level. This volume highlights contributions from a broad range of geological sub-disciplines currently striving to understand these critical intervals of geologically rapid, global-scale changes. * Provides updated, current models for the mid-Late Devonian and Permian-Triassic mass extinction episodes * Highlights several new analytical approaches for developing quantitative datasets * Takes an integrated approach presenting datasets from a broad range of sub-disciplines
