The Permo-Triassic period occurred approximately 248 million years ago; this is an era that witnessed the largest extinction that is ever known. According to research, about 95% of species and 60% of the genera phased out including marine organisms. The main cause of Permian extinction is thought to be volcanic eruptions, global cooling, and decrease in the continental shelf during the formation of Pangaea. The continental rearrangement and catastrophic extinction paved way to the rise of new mammals and dinosaurs.
