Long before dinosaurs, our planet was populated with plants and animals that were mostly obliterated after a series of massive volcanic eruptions in Siberia. The great Permian Extinction was possibly caused by a number of natural disasters, including possibly a collision with a comet, just like the end-Cretaceous extinction. Another possible cause might be an increased amount of volcanic activity around the world, with the infamous Siberian Traps being the possible epicenter of these eruptions. ...The end-Permian extinction occurred 252.2 million years ago, decimating 90 percent of marine and terrestrial species, from snails and small crustaceans to early forms of lizards and amphibians. “The Great Dying,” as it’s now known, was the most severe mass extinction in Earth’s history, and is probably the closest life has come to being ...Although the end-Permian was uniquely ruinous to life, it was probably just the end of a spectrum of warming-driven extinction events in Earth's history.

The Permian Extinction - the worst extinction in history PreThe K-T extinction was not the first such massive die-off This uncertain extinction threshold is varied around a central value that is calibrated by the end-Permian extinction (fig. S6; 17, 19). We also considered the widest possible range of species capacities to colonize new habitat, denoted 0 and 100% colonization (Fig. 1B; 19), using the median of these scenarios as our central extinction case. Previous ideas proposed for the Permian The end-Permian mass extinction event of roughly 252 million years ago – the worst such event in earth’s history – has been linked to vast volcanic emissions of greenhouse gases, a major temperature increase, and the loss of almost every species in the oceans and on land. Now, it seems that even the lakes and rivers were no safe havens.The worst mass extinction event was the Permian extinction, which occurred about 266 million to 251 million years ago.
