Recovery information may be outdated
The article that talks about recovery after the Permian-Triassic extinction appears to be from 1636 and according to newer research, the recovery of certain groups of marine animals, such as vertebrates, was likely quick. See http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0088987 for an example. — Preceding unsigned comment added by Vvardenfell (talk • contribs) 13:26, 23 November 2017 (UTC)
