Simply so, what caused the mass extinction of the Permian period?
"So we can rule out that ocean temperature was a driver of the extinction." The leading hypothesis is that the end-Permian extinction was caused by massive volcanic eruptions that spewed more than 4 million cubic kilometers of lava over what is now known as the Siberian Traps, in Siberia, Russia.
Furthermore, how did animals survive the Permian extinction? Due to the dry climate, the interior of Pangaea was mostly desert. In higher latitudes, gymnosperms survived and conifer forests began to recover from the Permian Extinction. Mosses and ferns survived in coastal regions. Spiders, scorpions, millipedes and centipedes survived, as well as the newer groups of beetles.
Beside this, what caused the great dying at the end of the Permian period?
Evidence for widespread ocean anoxia (severe deficiency of oxygen) and euxinia (presence of hydrogen sulfide) is found from the Late Permian to the Early Triassic. This spread of toxic, oxygen-depleted water would have devastated marine life, causing widespread die-offs.
When did the Permian mass extinction occur?
251.941 (+/- 0.037) million years ago - 251.88 (+/- 0.031) million years ago
