Permian extinction. Permian extinction - Carbon Cycle, Mass Extinction, Marine Life: The ratio between the stable isotopes of carbon (12C/13C) seems to indicate that significant changes in the carbon cycle took place starting about 500,000 to 1,000,000 years before the end of the Permian Period and crossing the boundary into the Induan Age (the ...The emplacement of the Siberian Traps, the Central Atlantic Magmatic Province (CAMP) and the Wrangellia have been linked to the end-Permian, the end-Triassic mass extinctions, and to the Carnian Pluvial Episode (CPE), respectively. Exploring the timing, eruptive styles, and volatile degassing of these Large Igneous Provinces (LIPs) is crucial to understand their causal link to the catastrophic ...The Capitanian (Guadalupian Series, Middle Permian) crisis is among the least understood of the major mass extinctions. It has been interpreted as extinction comparable to the "Big 5" Phanerozoic crises (Stanley and Yang, 1994; Bond et al., 2010a, 2015; Stanley, 2016) or, alternatively, as a gradually attained low point in Permian diversity of regional extent and therefore not a mass ...

The End-Permian Extinction, which occurred around 250 million years ago, marks the end of the Paleozoic Era. It destroyed over 96% of all life on Earth and defines the border from "old life" to "middle life", or the Mesozoic Era. The Mesozoic era began the reign of the dinosaurs with the remnants of the Permian Mass Extinction.The end-Permian extinction was arguably the most significant event in the past 600 million years of Earth's history (Raup and Sepkoski, 1982, Sepkoski, 1984; Fig. 1).The loss of over 90% of all species brought the Palaeozoic Era to an end, reduced biological diversity for the following 25 million years of the early Mesozoic, and shaped the subsequent course of the evolution of life toward ...
