Extinction Events: There have been numerous large extinction events in the Earth's history with some arguing that we're in the middle of the sixth extinction.

The Permian-Triassic mass extinction (PTME; ca. 252 Ma) coincided with rapid global warming that produced one of the hottest intervals of the Phanerozoic 1,2,3,4,5, which was likely triggered by ...The extinction began roughly 380 million years ago, midway through the segment of geologic time known as the Devonian period, or the age of fish. (Vertebrates hadn't yet made the leap onto land.) The prehistoric waters teemed not with the likes of tuna, sardines and salmon, but with their bizarre, long-dead predecessors.A recent study has examined climate change during the Permian-Triassic (P-Tr) boundary mass extinction using terrestrial sections. It is thought that global warming on Earth played a role in the 'Great Dying' that occurred about 252 million years (Ma) ago. Evidence of this temperature rise has been documented for tropical sea-surface ...It was an extinction event of truly epic proportions, one that dwarfed even the catastrophic bolide impact that wiped out the non-avian dinosaurs. Also known as the Great Dying, the Permian-Triassic mass extinction saw the disappearance of 96% of all marine species and 70% of terrestrial vertebrates.Evidence from correlative nonmarine strata elsewhere in the world containing fluvial Permian-Triassic boundary sections suggests that a catastrophic terrestrial die-off of vegetation was a global event, producing a marked increase in sediment yield as well as contributing to the global delta(13)C excursion across the Permians-Tri Jurassic …

The end-Permian mass extinction was the greatest biological calamity in the history of the planet. It is estimated that around fifty percent of marine families and perhaps ninety percent of marine species perished in the debacle—a loss of diversity unequaled in any other extinction event (Jin et al., 2000; Raup, 1979).Mar 27, 2020 · 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 ...
