This site discusses and defines a number of extinction concepts and provides a survey of some important extinction and extinction-like events, primarily from the Phanerozoic. There is information about species transitions, abrupt and mass extinctions, patterns and causal mechanisms of extinction, and isotope studies. Events that occurred during the Proterozoic, Vendian-Cambrian, Upper Cambrian (Dolgellian, Marjuman-Steptoean), Permian-Triassic, Triassic-Jurassic, and Cretaceous-Tertiary are discussed as well as extinction events of the modern era.
