What is the permian extinctionWhat is the permian extinction - The largest mass extinction in Earth's history occurred at the end of the Permian period, about 250 million years ago. In this catastrophe, it is estimated that more than 95% of marine species on Earth went extinct. Marine species with calcium carbonate shells and skeletons suffered worst. About 70% of terrestrial vertebrate species (land animals) suffered the same fate.

The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event, the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated with the eruption of the Siberian Traps. These plants and animals died off at about the same time, during the end of the Permian period—around 252 million years ago—and the beginning of the Triassic Period.

Mass extinctions are episodes in which a large number of plant and animal species become extinct within a relatively short period of geologic time—from possibly a few thousand to a few million years. After each of the five major mass extinctions that have occurred over the last 500 million years, life rebounded.Highlights of the Permian.
