The end-Permian mass extinction, the most severe biotic crisis in the Phanerozoic, was accompanied by climate change and expansion of oceanic anoxic zones. The partitioning of sulfur among different exogenic reservoirs by ...

In post-Cambrian time, life on Earth experienced five major extinction events, likely instigated by adverse environmental conditions. Biodiversity loss among marine taxa, for at least three of these mass extinction events ...

Changes in plankton productivity have been connected with the end-Permian mass extinction. A box-model – proxy data comparison suggests that an increase of microbial sulfate reduction (MSR) can explain excursions in δ34SCAS ...
