The Permian-Triassic mass extinction is one of five catastrophic events the planet has experienced throughout its geological history. Although it is popular belief that the extinction process in which the dinosaurs disappeared has been the most devastating, it is not.The Permian mass extinction came closer than any other extinction event in the fossil record to wiping out life on Earth. Yet the extinctions of species were selective and uneven. Finding a cause that would affect both land-dwelling and marine organisms is challenging.

Jul 15, 2023 · The Early Triassic after the end-Permian mass extinction was a time of repeated environmental degradation, which delayed biotic recovery.
