The final extinction of Permian biota both on land and in the sea ( 1 ) occurred at the climax of the superanoxia.Marine primary productivity is a key control on the stability of marine ecosystems. Decreasing marine primary productivity might have led to the end-Permian mass extinction, although this is debated. However, the changes in primary productivity at different seawater depths during the end-Permian mass extinction remain poorly constrained.
