The timing of the postextinction recovery is not well constrained, although on the basis of unpublished data, we prefer an estimate of approximately 5 million years, which is similar to the estimate of more than 3 million years for the recovery of marine ecosystems after the end-Cretaceous extinction (ref. 4; see also ref. 5 ).One of the most current theories for the mass extinction of the Permian is an agent that has been also held responsible for the Ordovician and Devonian crises, glaciation on …Thus, it's looking increasingly like The Great Dying was more staggered than we thought.
