Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially as the Great Dying) [7] [8] forms the boundary between the Permian and Triassic geologic ...

2024年12月20日 · The Permian extinction was characterized by the elimination of about 90 percent of the species on Earth, which included more than 95 percent of the marine species and 70 percent of the terrestrial species. In addition, more than half of all taxonomic families present at the time disappeared.

About 250 million years ago, at the end of the Permian period, something killed some 90 percent of the planet's species. Less than 5 percent of the animal species in the seas survived. On land...

2018年12月6日 · Scientists have debated until now what made Earth's oceans so inhospitable to life that some 96 percent of marine species died off at the end of the Permian period. New research shows the "Great Dying" was caused by global warming that left ocean animals unable to …

2022年7月22日 · The Permian-Triassic extinction, aka the Great Dying, eradicated more than 90 percent of earth’s marine species and 75 percent of terrestrial species 252 million years ago. It was the deadliest mass extinction event in the history of our planet, and its legacy lives on in the flora and fauna of the modern world.

2017年1月23日 · The Permian extinction—the worst extinction event in the planet's history—is estimated to have wiped out more than 90 percent of all marine species and 70 percent of land animals.

The largest mass extinction in the Earth’s history occurred during the latter part of the Permian Period. This mass extinction was so severe that only 10 percent or less of the species present during the time of maximum biodiversity in the Permian survived to the end of the period.

2002年1月28日 · 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.

2025年1月24日 · On land, four-legged vertebrates and plants suffered significant reductions in diversity across the Permian-Triassic boundary. Only 30 percent of terrestrial vertebrate genera survived into the Triassic. Many possible causes have been …

2023年4月28日 · The largest extinction event in Earth’s history—far more devastating than the more famous Cretaceous extinction when the dinosaurs disappeared—marks the end of the Permian. Scientists estimate that more than half (53%) of all taxonomic families were lost.
