Here, we assess the changes in wildfire activity in the high-latitude lowlands of eastern ...Although the end-Permian was uniquely ruinous to life, it was probably just the end of a spectrum of warming-driven extinction events in Earth's history. If the environmental conditions that led ...The End-Permian Mass Extinction (EPME) (also known as Permian-Triassic Mass Extinction, PTME) is one of the most studied geobiological events of the past. It is the most severe mass extinction of all life—"the mother of all extinctions"—and promoted the evolution of modern ecosystems (e.g., Raup and Sepkoski 1982; Erwin 1993, 2006).extinction? 3. 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 somePermian Period - Geology, Extinction, Climate: The Permian Period is subdivided into Early (Cisuralian), Middle (Guadalupian), and Late (Lopingian) epochs corresponding to the Cisuralian, Guadalupian, and Lopingian rock series. Rocks laid down during these epochs and ages have been assigned to corresponding depositional series and stages, respectively.The demise of this predator and the end of the entire Permian era 250 million years ago was caused by global warming and volcanic activity. The 'Great Dying' is the most intense extinction wave ever, including the extinction of up to 95 % of all species (Benton and Twitchett 2003). The restoration of species diversity took 10-20 million ...
