The fourth and final suggestion that paleontologists have formulated credits the Permian mass extinction as a result of basaltic lava eruptions in Siberia. These volcanic eruptions were large and sent a quantity of sulphates into the atmosphere. Evidence in China supports that these volcanic eruptions may have been silica-rich, and thus ... Oct 2, 2017 · 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. The end-Permian mass extinction (EPME) at ∼252 Ma was the most severe extinction in the Phanerozoic. Marine ecosystems devastated by the EPME had a highly prolonged recovery, and did not substantially recover until after the Smithian–Spathian substage boundary (SSB) of the Lower Triassic (5 to 9 Ma after the EPME).

The end-Permian mass extinction (EPME) is one of five deep-time intervals when Earth System perturbations resulted in extreme biodiversity loss, resetting the trajectory of life, and leading to a new biological world order. Erwin (1996) coined this critical interval in Earth history as the “Mother of Mass Extinctions”. The available data at the time led the geoscience community to ...

The latter (synapsida) were the most important and successful Permian animals. The end of the Permian saw a major turnover in fauna during the Permian–Triassic extinction event: probably the most severe mass extinction event of the phanerozoic. There was a protracted loss of species, due to multiple extinction pulses.

New research from the University of Washington and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe.

Mar 1, 2022 · The end-Permian mass extinction (EPME) was known as the most severe biocrisis of the past 600 Ma.
