It happened about 252 million years ago, and, over the course of just tens of. The most extensive mass extinction took place about 252 million years ago. But the exact cause and the sequence of events that led to the mass extinction remained highly controversial
The extinction 252 million years ago was so dramatic and widespread that scientists call it The Great Dying. The catastrophe killed off more than 95 percent of life on Earth over the course of hundreds of thousands of years, said researchers from the University of Cincinnati (UC) in the US Hello, and welcome back to Extinction's past, present, and future. In this class, we'll talk about the worst of all past mass extinctions, the one geoscientists cheerfully nicknamed The Great Dying.

The Late Devonian Extinction was less severe than the other mass extinctions. At least 70% of all species went extinct . It occurred 375-360 million years ago at the end of the Frasnian Age and in the Devonian Period. This mass extinction lasted for over 20 million years. Though opinions vary, the biggest evidence is attributed to global anoxia One of the key effects of the end-Permian mass extinction, 252 million years ago, was rapid heating of tropical waters and atmospheres. How this affected life on land has been uncertain until now
The most extensive mass extinction took place about 252 million years ago. It marked the end of the Permian Epoch and the beginning of the Triassic Epoch. About three quarters of all land life and about 95 percent of life in the ocean disappeared within only a few thousand years Eddie Gonzales Jr. - MessageToEagle.com - The most extensive mass extinction took place about 252 million years ago.It marked the end of the Permian Epoch and the beginning of the Triassic Epoch. About three-quarters of all land life and about 95 percent of life in the ocean disappeared within only a few thousand years The mass deaths began in shallow sea areas. Eventually it spread deeper into the ocean. The researchers were able to find evidence of this on Svalbard because they studied both what was a shallow sea and what was a slightly deeper sea 252 million years ago The mass extinction at the boundary of the Permian and Triassic eras 252 million years ago was caused by the acidification of the world's oceans, as a consequence of an increase in atmospheric carbon dioxide. The Permian Extinction - sometimes called the Great Dying - seemed to all but obliterate life in the oceans, and perhaps on land The severest mass extinction occurred in the Late Permian period 251 to 252.2 million years ago. It lasted only 20,000 years and decimated over 95 percent of life on Earth in what became known as the Great Dying. Its causes remain a geological mystery

With more than 95% of marine species becoming extinct, life in Permian seas, once a thriving and diverse ecosystem, was wiped out within only tens of thousands of years, a geological blink of an eye 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 The end-Permian extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the Earth's most severe mass extinction that peaked about 252.3 million years ago
The end-Permian mass extinction was the most severe biodiversity crisis in Earth history. To better constrain the timing, and ultimately the causes of this event, we collected a suite of geochronologic, isotopic, and biostratigraphic data on several well-preserved sedimentary sections in South China. High-precision U-Pb dating reveals that the extinction peak occurred just before 252.28 ± 0. An extinction-level event (also known as a mass extinction or biotic crisis) is a widespread and rapid decrease in the biodiversity on Earth.Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms.It occurs when the rate of extinction increases with respect to the rate of speciation.Estimates of the number of major mass extinctions in the last. . Instead, scientists have found that the extinction of a wide variety of species was not linked to any single catastrophic event
. But this extinction was preceded by a burst of biodiversity in the Cambrian Period, then an even bigger burst in the Ordovician Unlike other mass extinction events, this extinction event happened relatively recently, only 66 million years ago. Also unlike the other extinction events, scientists have a fairly good idea of what caused the massive extinction. An asteroid crater in the Gulf of Mexico was found that dated to the time of the extinction

Five major mass extinctions are generally recognised.This comes from a landmark paper published in 1982. There Jack Sepkoski and David M. Raup identified the five. The biggest most dramatic was the third one, the Permian-Triassic extinction event about 252 million years ago. 57% of all families, 83% of all genera and 90% to 96% of all species were wiped out, and yes this is the event that. The Permian extinction did not happen 252 million years ago it stopped at that time. That date is the low point in biodiversity - the point where rate of arrival of new species equals the rate of extinctions. The decline in biodiversity started 10 to 15 million years before that and increased gradually to the trough at 252 mya 252 million years ago. The worst extinction event, killing 90 to 96 per cent of species. The cause is debated but could have been a meteorite, volcanism or methane release that led to rapid climate change.

Mass extinction at the end of the Permian Period Scientists estimate about 90% of the plant and animal species on Earth during the Permian Period were extinct by the end of the period. Marine animals living in reefs and shallow waters were especially hard hit, and the loss of marine species reached about 96%
A mass extinction is a sharp spike in the rate of extinction of species caused by a catastrophic event or rapid environmental change. Scientists have been able to identify five mass extinctions in Earth's history, each of which led to a loss of more than 75 percent of animal species. 1. ORDOVICIAN-SILURIAN EXTINCTION 440 MILLION YEARS AGO (MA The most extensive mass extinction took place at the end of the Permian—approximately 252 million years ago. During this mass extinction, there was a shift from the divergence of the Paleozoic reptiles and marine animals such as trilobites and brachiopods to Mesozoic dinosaurs as well as marine animals such as mollusks
Another mass extinction - the 'End-Permian' extinction, 252 million years ago - provides further evidence for how rapidly things can go awry.

The extinction events divided the Cretaceous Period (which marked the end of the Mesozoic Era) and the Tertiary. It happened about 252 million years ago and geological evidence shows that it may have taken no more than 200,000 years. In terms of geological time the extinction occurred quickly. Who became extinct? Important groups of marine animals disappeared at the end-Permian extinctions

Several ideas have been proposed for what devastated marine life, but scant direct evidence exists. Clarkson et al. measured boron isotopes across this period as a highly sensitive proxy for seawater pH. It appears that, although the oceans buffered the acidifiying effects of carbon. Mass extinctions are episodes in which a large number of plant and animal species become extinct within a relatively short period of geologic time—from possibly a few thousand to a few million years. After each of the five major mass extinctions that have occurred over the last 500 million years, life rebounded
Earth's largest-ever mass extinction event 252 million years ago may have been greatly exacerbated by a thinning ozone layer, researchers have discovered..
