During the recovery of life in the Triassic Period, the relative importance of land animals grew.The largest extinction event in Earth’s history—far more devastating than the more famous Cretaceous extinction when the dinosaurs disappeared—marks the end of the Permian. Scientists estimate that more than half (53%) of all taxonomic families were lost.That cataclysmic event, the largest mass die-off in planetary history, has become fittingly known as the Great Permian Extinction, and also happens to serve as the end line for the entire Paleozoic era. Trilobites evolved continually throughout their incredibly long march through “deep time” history. During that extended stay they inhabited ...

About 90% of the species living at the time went extinct, including most of the dominant land vertebrates at the time, the synapsids. Scientists are studying this event to figure out whether it was caused by climate change, volcanic eruptions, sea level change ...In fact, this mass extinction was really 8-10 different extinction events over 20 million years; compounded together, they created one massive loss of genetic diversity, as about 75% of the world ...(Phys.org)—The Permian geologic period that ended the Paleozoic era climaxed around 252 million years ago with a sweeping global mass extinction event in which 90 to 95 percent of marine life ...Updated on March 17, 2017.

End-Permian extinction: trigger and kill mechanisms The event that ended the Paleozoic Era is generally regarded as the most severe of all recorded mass ex-tinctions [10]. Estimates of proportional diversity loss depend on the metric and time frame adopted, but compilations by Sepkoski [11,12] indicate that someTo test the predicted intensity of regional extinction, we used fossil occurrence data to estimate the extirpation of marine genera across the end-Permian extinction .
