Some 252 million years ago, life on Earth faced the “Great Dying”: the Permian-Triassic extinction. The cataclysm was the single worst ... Permian Extinction. The largest extinction ever in the history of Earth is the Permian extinction, an event that occurred roughly 252 million years ago. Scientists estimate that 90 percent of marine species disappeared over the course of about 60,000 years. The extinction was a response to dramatic changes in the Earth's atmosphere. "The end-Permian mass extinction may be less well known than the end-Cretaceous, but it was by far the biggest mass extinction of all time. Perhaps as few as 10 percent of species survived the end of the Permian, whereas 50 percent survived the end of the Cretaceous. Fifty percent extinction was associated with devastating environmental upheaval.

During the end-Permian extinction, a substantial amount of methane (CH4) was likely released into the ocean-atmosphere system associated with the Siberian Traps volcanism, although fluctuations in the global CH4 cycle in the aftermath of the extinction remain poorly understood. The carbon (C) isotopic composition of carbonate (δ13Ccarb) across the Permian-Triassic boundary (P-TB) was analyzed ...

The mass extinction at the end of the Permian Period 252 million years ago — one of the great turnovers of life on Earth — appears to have played out differently and at different times on land and in the sea, according to newly redated fossils beds from South Africa and Australia.

TLDR. This study tests the concept of refugia by examining the fate of a single community that lived ∼50 k.y. after the end-Permian mass extinction in Shangsi, south China, and found that the microbial community was vital to the success of the refuge, acting as a stable substrate, food source, and oxygen supply. 29.

The release of greenhouse gases, augmented by the positive climate feedback of melting permafrost, is the probable cause of the large negative δ 13 C excursion during the PTTI (Joachimski et al., 2019).10) Permian extinction - the Great Dying At the end of the Permian period, most of life on Earth would be wiped out. According to Britannica , that includes the elimination of about half of all families, approximately 95 percent of marine species, and about 70 percent of land species.2014) indicate stable temperatures in the pre-extinction phase of the late Permian (Fig. 3D). A gradual pre-extinction warming, as indicated by the ostracod-based data, was also suggested from brachiopod data in South China (Wang et al. 2020), but this observation is based on a very limited number of specimens in this key time interval.anoxia has long been invoked both as a cause of the extinction (6-8) and as a barrier to rediversification (9). Numerous lines of evidence demonstrate widespread anoxic conditions around the time of the end-Permian mass extinction (e.g., refs. 6 and 10-12). In contrast, the prevalence of anoxia during the 5- to 10-million-Oct 19, 2020 · The end-Permian mass extinction was linked with ocean acidification due to carbon degassing associated with Siberian Trap emplacement, according to boron isotopes from fossil shells and ...
