Detailed explanation-1: -The largest extinction in Earth’s history marked the end of the Permian period, some 252 million years ago. Long before dinosaurs, our planet was populated with plants and animals that were mostly obliterated after a series of massive volcanic eruptions in Siberia.
Detailed explanation-2: -Permian–Triassic Extinction (Great Dying) Earth’s largest extinction event in history killed 96% of all marine species and an estimated 70% of land species, including insects. The Permian-Triassic Extinction was such a devastating event that it had the nickname the “Great Dying” because of its significance.
Detailed explanation-3: -252 Million Years Ago: Permian-Triassic Extinction But you don’t get a nickname like the Great Dying for playing favorites; almost no form of life was spared by this extinction, which caused the disappearance of more than 95 percent of marine species and upward of 70 percent of land-dwelling vertebrates.
