The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover. Recovery of life in the sea may have been much faster.A. The extinction rate between the end-Permian and the end-Triassic extinctions indicates this was a time of global ecological stress. (Choice B) The tetrapod families that were lost during the end-Permian extinction returned after a lag of a few million years as they re-populated previously occupied habitats. B.Pseudophillipsia (Late carboniferous to Late Permian) Final extinction.
