Mass Extinctions and Their Aftermath

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.
