  • “Rapid” Recovery The Permian-Triassic extinction 252 million years ago was Earth's most severe biotic crisis since the Precambrian and is thought to have depressed diversity in its wake for millions of years. Brayard et al. (p. 1118; see the Perspective by Marshall and Jacobs) show, however, that ammonoids, a large group of marine organisms that were severely affected, recovered remarkably quickly. Only 1 million years after the extinction, ammonoids had recovered to levels higher than in the… CONTINUE READING
