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. -

Complements the many popular and often sensational accounts, multi-author volumes, and studies on a particular mass extinction with a focuses scientific investigation of all the known mass extinctions with sufficient technical detail to excite geologists and paleontologists. Discusses the Big Five, one late in each of the Ordovician, Devonian, Permian, Triassic, and the famous Cretaceous that saw the end of the Dinosaurs; and minor mass extinctions from the early Cambrian the Cenozoic. Also examines the current paleontological, geological, and sedimentological evidence of environmental change; and sets out the cases for causes by climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions.

"260 million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst--the end-Permian extinction--wiping out nearly every species on the planet. This book delves into the mystery behind these extinctions and sheds light on the fateful role the primeval supercontinent, known as Pangea, may have played in causing these global catastrophes. Drawing on the latest discoveries as well as his own field expeditions to remote corners of the world, Paul Wignall reveals what scientists are only now beginning to understand about the most prolonged period of environmental crisis in Earth's history. He describes how a series of unprecedented extinction events swept across the planet in a span of eighty million years, rapidly killing marine and terrestrial life on a scale more devastating than the dinosaur extinctions that would come later. Wignall shows how these extinctions--some of which have only recently been discovered--all coincided with gigantic volcanic eruptions of flood basalt lavas that occurred when the world's landmasses were united into a single vast expanse. Unraveling one of the great enigmas of ancient Earth, this book also explains how the splitting apart of Pangea into the continents we know today ushered in a new age of vibrant and more resilient life on our planet." -- Publisher's description

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 becomeextinct.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.

This new anthology, which integrates explanatory text, primary source readings, and case studies, provides students of any major (philosophy, science, or other) with an accessible and comprehensive introduction to the philosophy of science. The anthology is organized around a unique “three-pronged” approach: the metaphysical (what), the epistemological (how), and the axiological (why). The coverage of issues builds coherently and logically: from issues of scientific method to ethical issues, to the most current social and political implications of science — demonstrating how philosophy of science is relevant in a modern day context. The anthology carefully examines the theoretical apparatus of the philosophy of science and applies it to rich case studies from the history of science.

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.

In Catastrophes and Lesser Calamities, renowned geologist Tony Hallam takes us on a tour of the Earth's history, and of the cataclysmic events, as well as the more gradual extinctions, that have punctuated life on Earth throughout the past 500 million years. While comparable books in this field of study tend to promote only one likely cause of mass extinctions, such as extraterrestrial impact, volcanism, and or climatic cooling, Catastrophes and Lesser Calamities breaks new ground, as the first book to attempt an objective coverage of all likely causes, including sea-level and climatic changes, oxygen deficiency in the oceans, volcanic activity, and extraterrestrial impact. - ;In Catastrophes and Lesser Calamities, renowned geologist Tony Hallam takes us on a tour of the Earth's history, and of the cataclysmic events, as well as the more gradual extinctions, that have punctuated life on Earth throughout the past 500 million years.

Hallam focuses on the so-called 'big five' mass extinctions, at the end of the Ordovician, Permian, Triassic, and Cretaceous periods, and the later Devonian, and he also includes less well-known examples where relevant. He devotes attention especially to the attempts by geologists to distinguish true catastrophes from more gradual extinction events, and he concludes with a discussion of the evolutionary significance of mass extinctions, and on the influence of Homo sapiens in causing extinctions within the last few thousand years, both on land and in the seas. -

Picture a world of dog-sized scorpions and millipedes as long as a car; tropical rainforests with trees towering over 150 feet into the sky and a giant polar continent five times larger than Antarctica. That world was not imaginary; it was the earth more than 300 million years ago in the Carboniferous period of the Paleozoic era. In Carboniferous Giants and Mass Extinction, George R. McGhee Jr. explores that ancient world, explaining its origins; its downfall in the end-Permian mass extinction, the greatest biodiversity crisis to occur since the evolution of animal life on Earth; and how its legacies still affect us today. McGhee investigates the consequences of the Late Paleozoic ice age in this comprehensive portrait of the effects of ancient climate change on global ecology. Carboniferous Giants and Mass Extinction examines the climatic conditions that allowed for the evolution of gigantic animals and the formation of the largest tropical rainforests ever to exist, which in time turned into the coal that made the industrial revolution possible—and fuels the engine of contemporary anthropogenic climate change. Exploring the strange and fascinating flora and fauna of the Late Paleozoic ice age world, McGhee focuses his analysis on the forces that brought this world to an abrupt and violent end. Synthesizing decades of research and new discoveries, this comprehensive book provides a wealth of insights into past and present extinction events and climate change.
