Mass extinction permian
The end-Permian extinction (EPE) was one of the most severe mass extinctions in the history of metazoan life. The effects of the EPE were pronounced for marine organisms, including a nearly ...After some mass extinction recoveries (e.g., after the End-Triassic extinction recovery), the rate of diversification is relatively slow, reflected in a gradually sloping line. After other mass extinctions (e.g., the End-Permian mass extinction), the standard rate of diversification is much quicker and new species are churned out at a rapid ...

The end-Permian mass extinction (252.3 Ma) was an abrupt and severe loss of diversity on land and in the oceans, the largest extinction of the Phanerozoic. Recent palaeontological, geochemical and ...It has been hypothesized that Siberian Traps volcanism caused enhanced weathering and collapse of vegetation on land before the end-Permian mass extinction, thereby modulating the flux of bioavailable phosphorus and, thus, marine productivity and redox conditions (Schobben et al., 2020).quences of major extinctions and other events in the history of life. Inthis paper,we explore the relationships among physiology, evolutionary history, and environ-mental catastrophe through the example of end-Permian mass extinction and its aftermath. We argue that ex-tinction resulted from the synergistic effects of severalThe end-Permian mass extinction was the most catastrophic event for life in the Phanerozoic eon because it impacted numerous organisms, from micro-sized photosynthetic organisms to large (meter ...
At the end of the Permian period, around 252 million years ago, approximately 70% of life on land and 90% of species in the oceans went extinct. Determining the cause of this extinction, which was the most severe in Earth's history, requires a high-quality timeline of precisely when the extinction began and how quickly it progressed.end-Permian mass extinction to diversify during the.
