The end-Permian (c. 252 Ma) and end-Triassic (c. 201 Ma) mass-extinction events are commonly linked to the emplacement of the large igneous provinces of the Siberia Traps and Central Atlantic Magmatic Province, respectively.Accordingly, scenarios for both extinctions are increasingly convergent and cross-fertilization of ideas has become important.The Permian is the last Period of the Paleozoic Era. It ended with the greatest mass extinction known in the last 600 million years. Up to 90% of marine species disappeared from the fossil record, with many families, orders, and even classes becoming extinct. On land insects endured the greatest mass extinction of their history.Similarly, 250 million years ago, the world saw the worst mass extinction event in history: the End-Permian Extinction. Also known as the Great Dying, the event was caused by a series of volcanic ...

Mercury (Hg) emissions associated with the emplacement of Large Igneous Provinces (LIPs) were first recognized by Sanei, Grasby & Beauchamp (Reference Sanei, Grasby and Beauchamp 2012), who showed a large Hg spike associated with the Siberian Traps eruptions.This event was coincident with the Latest Permian Extinction (LPE), the largest extinction in Earth's history that had a ...In the modern world, we tend to think of extinction as the loss of species of animals and plants. Sometimes those species are also the last members of major groups. For example, the extinction of the last species of trilobite at the end of the Permian Period terminated a group of marine arthropods that existed on Earth for more than 250 million ...At the end of the Permian period, around 252 million years ago, approximately 70% of life on land and 90% of species in the oceans went extinct. Determining the cause of this extinction, which was the most severe in Earth’s history, requires a high-quality timeline of precisely when the extinction began and how quickly it progressed.
