Mass extinctions can be either gradual or sudden. The process of extinction follows five different phases: First is the extinction phase, which features a rapid decrease in biotic diversity. The second phase is the survival phase. The mother of all mass extinctions, the Permian-Triassic Extinction Event was a true global catastrophe, wiping out an unbelievable 95 percent of ocean-dwelling animals and 70 percent of terrestrial animals.
