Permian–Triassic extinction event (End Permian): 252 Ma, at the Permian – Triassic transition. [13] Earth's largest extinction killed 53% of marine families, 84% of marine genera, about 81% of all marine species [14] and an estimated 70% of terrestrial vertebrate species. [15] This is also the largest known extinction event for insects. [16]Permian Extinction: 250 million years ago, huge numbers of species on our planet vanished from the fossil record. Called the Permian extinction, only a lucky few percentage of animals survived to the next era, the Mesozoic.Permian Extinction: 250 million years ago, huge numbers of species on our planet vanished from the fossil record.

It is the most severe mass extinction of all life—"the mother of all extinctions"—and promoted the evolution of modern ecosystems (e.g., Raup and Sepkoski 1982; Erwin 1993, 2006).Even during the Permian-Triassic extinction, which was the worst extinction event so far in terms of die off, the CO2 still rose at a slower rate. It was probably still related to carbon fuels though: the Siberian Traps that kept erupting over several thousand years or more are theorized to have erupted up through a giant bed of carbon rich ...Of the five major extinctions, the End-Permian proved to be the most massive — the mother of all extinction events.

Perhaps the most dramatic example of the potential impact of plate tectonics on life occurred near the end of the Permian Period (roughly 299 million to 252 million years ago).

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 occurred 215 million years ago and found that the cause of ...- Before the Mid-Permian, radiolarian cherts contained hematite, a highly oxidized iron mineral. The presence of hematite indicates that the deep ocean was oxygen-rich - at the end-mid-permian extinction gray sediments suddenly replaced red chert, signaling the onset of low-oxygen in the deep seaThe Siberian Traps are believed to be the primary cauThe end-Permian extinction is perhaps best asso The end of the Permian was characterized by the greatest mass extinction event in Earth's history. 252 million years ago, a series of volcanic eruptions in Siberia led to a massive release of greenhouse gases.

The end-Permian mass extinction, which their study calls the “most severe biodiversity crisis in earth history,” wiped out 95% of marine life ...A singular event. 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.A mass extinction is a short period of geological time in which a high percentage of biodiversity, or distinct species—bacteria, fungi, plants, mammals, birds, reptiles, amphibians, fish, invertebrates—dies out. In this definition, it’s important to note that, in geological time, a ‘short’ period can span thousands or even millions of years.Permian: [adjective] of, relating to, or being the last period of the Paleozoic era or the corresponding system of rocks — see Geologic Time Table.
