The smaller, at the end of a time interval called the Capitanian, occurred about 260 million years ago.

The Permian extinction, 251.4 million years ago, devastated the marine biota: tabulate and rugose corals, blastoid echinoderms, graptolites, the trilobites, and most crinoids died out. One lineage of crinoids survived, but never again would they dominate the marine environment. Paleozoic fossil localitiesSome beds dated from the latest Permian ages are renowned for their fossils; strata (rock layers) in the Russian Platform contain a remarkable vertebrate faunal assemblage as well as fossil insects and plants. The Permian Period derives its name from the Russian region of Perm, where rocks deposited during this time are particularly well developed.Roughly 250 million years have passed since Earth experienced an extinction so profound, it's become colloquially known as the Great Dying.

Distinguished vertebrate paleontologist Michael J. Benton's latest book, "When Life Nearly Died: The Greatest Mass Extinction Of All Time", is a long overdue popular account of the worst mass extinction in Earth's history, the end Permian extinction of approximately 251 million years ago."The end-Permian mass extinction may be less well known than the end-Cretaceous, but it was by far the biggest mass extinction of all time. Perhaps as few as 10 percent of species survived the end of the Permian, whereas 50 percent survived the end of the Cretaceous. Fifty percent extinction was associated with devastating environmental upheaval.The organisms of the Guiyang biota lived around 251 million years ago, just one million years after the world’s worst known mass-extinction event, at the end of the Permian period.
