What is the permian extinction
In the geologic timescale, the Capitanian is an age or stage of the Permian.It is also the uppermost or latest of three subdivisions of the Guadalupian Epoch or Series.The Capitanian lasted between 264.28 and 259.51 million years ago. It was preceded by the Wordian and followed by the Wuchiapingian.. A significant mass extinction event occurred at the end of this stage, which was associated ...The end-Permian mass extinction, which took place 251.9 million years ago, killed off more than 96 percent of the planet's marine species and 70 percent of its terrestrial life—a global...

These are the Cretaceous-Paleogene extinction event (~65 million years ago), the Triassic-Jurassic extinction event (~200 million years ago), extinction near the Permian-Triassic boundary (~260 million years ago), the late Devonian extinction (~380 million years ago), and extinction near the Ordovician-Silurian boundary (~440 million years ago). The end-Permian extinction occurred 252.2 million years ago, decimating 90 percent of marine and terrestrial species, from snails and small crustaceans to early forms of lizards and amphibians. “The Great Dying,” as it’s now known, was the most severe mass extinction in Earth’s history, and is probably the closest life has come to being ...The end-Permian extinction (EPE), the most severe biotic crisis of the Phanerozoic (Wignall, 2015), led to the fundamental restructuring of terrestrial and marine ecosystems.The consensus view is that the EPE occurred as a consequence of Siberian Traps volcanism, which generated large volumes of sulfate aerosols and CO 2 over a short interval (Burgess et al., 2017), with further contributions ...A team of scientists has found new evidence that the Great Permian Extinction, which occurred 252 million years ago was caused by massive volcanic eruptions in what is now Siberia, which led to catastrophic environmental changes. The above shows parts of the volcanic rock today. Image courtesy of Linda Elkins-Tanton.
Evidence of the Permian catastrophe is abundant and clear, but what was the culprit? Researchers are looking for clues in the geology and chemistry of Earth and its oceans. Prime Suspects. Gregory Retallack is a geologist at the University of Oregon. His prime suspect for the Permian extinction is an asteroid smashing into the Earth. A team of ...The end-Permian extinction was the most influential on the physiological composition of the marine fauna (figure 2c,f), whether or not physiological selectivity is adjusted for tiering. After adjusting for tiering, the Frasnian/Famennian, end-Triassic and Pliensbachian/Toarcian events also exhibit a relatively strong influence ( figure 2 f ).The Permian-Triassic extinction. The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the ...Usually, extinction operates at a fairly constant rate, culling some species while speciation generates new ones. However, at a few points in life's history the humdrum of regular extinction has been interrupted by mass extinctions. Learn more about these biodiversity crises. View details >>
