But The Long Dead Venusians story (whether or not it happened in the manner that Mitski sings about, or happened at all) rather stymies our self-congratulatory instincts. ...recovery of end permian extinction took millions of years. In many ways the Triassic can be thought of as the time when the earths biota started to become modern During this time we get the first mammals, dinosaurs, lizards, turtles, frogs, salamanders etc Can be called the Dawn of Modern Ecosystems Mollusks were abundant, bivalves, sea urchins.The Permian extinction appears to have happened in two or three pulses of extinction. Two or more separate impacts could have possibly accounted for these pulses. Some possible evidence for impact events are meteorite fragments in Australia, rare shocked quartz in both Australia and Antarctica, and craters in Australia.Here, new Bayesian analyses suggest that diversification turnover between the two was not driven by biotic competition but the end-Permian extinction.

Aug 25, 2023 · Permian Period, in geologic time, the last period of the Paleozoic Era, lasting from 298.9 million to 252.2 million years ago. The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.
