The Permian extinction reminds him of Agatha Christie's Murder on the Orient Express, in which a corpse with 12 knife wounds is discovered on a train. Twelve different killers conspired to slay the victim. Erwin suspects there may have been multiple killers at the end of the Permian.

The end-Permian mass extinction was the greatest biological calamity in the history of the planet. It is estimated that around fifty percent of marine families and perhaps ninety percent of marine species perished in the debacle—a loss of diversity unequaled in any other extinction event (Jin et al., 2000; Raup, 1979).On land, more than sixty percent of vertebrate families seem to have ...The end-Permian extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the Earth's most severe mass extinction that peaked about 252.3 million years ago.
