An ‘end-Guadalupian’ extinction, distinct from that at the end of the Permian, was first recognized in the marine realm in the 1990s [1,2].Shortly afterwards it was calculated to be one of the most catastrophic extinction events of the Phanerozoic [] and since then a considerable body of work has attempted to explore it, focusing on carbonate platforms of southern China ...The Permian-Triassic Extinction was such a devastating event that it had the nickname the “Great Dying” because of its significance.

Some call ...For an extinction event to be considered as a major extinction event, at least half of all the life forms existing during that period under review must be wiped out.

According to a new study, the mass extinction that occurred 215 million years ago was not caused by an asteroid hitting Earth or by climate change. A team of University of Rhode Island scientists and statisticians conducted a sophisticated quantitative analysis of a mass extinction that ...Scientists call it the Permian-Triassic extinction or "the Great Dying" -- not to be confused with the better-known Cretaceous-Tertiary extinction that signaled the end of the dinosaurs 65 million years ago. Whatever happened during the Permian-Triassic period was much worse: No class of life was spared from the devastation.

Around the time of the end-Permian extinction, scientists have found that the Earth was likely experiencing a sudden and massive disruption to the carbon cycle, abnormally high air and sea temperatures, and an increasingly acidic ocean — all signs of a huge and rapid addition of greenhouse gases to the atmosphere.Death by acid was the fate of the sea monsters that perished in Earth's biggest mass extinction, some 251 million years ago, a new study finds. Nearly every form of ocean life disappeared during ...At the Permian–Triassic boundary (252 million years ago), a series of environmental crises triggered by the Siberian Traps eruptions caused the extinction of 81–94% of marine species and 70% ...The Permian extinction wiped out 70 percent of known land species. Those who survived had to get creative. Others fought for their last gasp.
First, we need to be clear on what we mean by ‘mass extinction’. Extinctions are a normal part of evolution: they occur naturally and periodically over time. 1 There’s a natural background rate to the timing and frequency of extinctions: 10% of species are lost every million years; 30% every 10 million years; and 65% every 100 million …End Permian (252 million years ago): Earth’s largest extinction event, decimating most marine species such as all trilobites, plus insects and other terrestrial animals.
