It is Earth 's most severe known extinction event, [10][11] with the extinction of 57% of biological families, 83% of genera, 81% of marine species [12][13][14] and 70% of terrestrial vertebrate species. [15] It is also the greatest known mass extinction of insects. [16]
30 lis 2022 · We see the spikes in extinction rates marked as the five events: End Ordovician (444 million years ago; mya) Late Devonian (360 mya) End Permian (250 mya) End Triassic (200 mya) – many people mistake this as the event that killed off the dinosaurs. But in fact, they were killed off at the end of the Cretaceous period – the fifth of the "Big ...
22 lut 2022 · The Permian–Triassic mass extinction (252 million years ago) substantially reduced global biodiversity, with the extinction of 81–94% of marine species and 70% of terrestrial vertebrate...
24 wrz 2024 · 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.
23 sty 2017 · 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.
We present a high-precision age model for the end-Permian mass extinction, which was the most severe loss of marine and terrestrial biota in the last 542 My, that allows exploration of the sequence of events at millennial to decamillenial timescales 252 Mya.
28 lip 2020 · According to the most recent version of the International Chronostratigraphic Chart (v2019/5; Cohen et al. 2018), the boundary between the late Permian and the Early Triassic is set at a CA-ID-TIMS Uranium-Lead derived age of 251.902 ± 0.024 million years ago.
