Geochemical, biomarker, and isotopic evidence suggests that the end-Permian was characterized by extreme oceanic anoxia that may have led to hydrogen sulfide buildup and mass extinction. We use an earth system model to quantify the biogeochemical and physical conditions necessary for widespread oceanic euxinia and hydrogen sulfide release to the atmosphere. Greater than threefold increases in ocean nutrient content combined with nutrient-trapping ocean circulation cause surface-water H 2 S…

End-Permian marine extinction due to temperature-driven nutrient recycling and euxinia

Extreme warming at the end-Permian induced profound changes in marine biogeochemical cycling and animal habitability, leading to the largest metazoan extinction in Earth’s history. However, a causal

A nutrient control on marine anoxia during the end-Permian mass extinction

Oxygen deprivation and hydrogen sulfide toxicity are considered potent kill mechanisms during the mass extinction just before the Permian–Triassic boundary (~251.9 million years ago). However, the

Flourishing ocean drives the end-Permian marine mass extinction

Significance This study provides geochemical evidence that links some of the most important finds associated with the end-Permian mass extinction, including climate warming, enhanced weathering,

Eutrophication, microbial-sulfate reduction and mass extinctions

A plankton community turnover from a high-diversity eukaryote to high-biomass bacterial dominated food web is the catalyst proposed in this anoxia-extinction scenario and stands in stark contrast to the postulated productivity collapse suggested for the end-Cretaceous mass extinction.

Simulating Permian–Triassic oceanic anoxia distribution: Implications for species extinction and recovery

The biggest mass extinction in the Phanerozoic, at the end of the Permian, has been associ- ated with oceanic changes, but the exact dynamics are still debated. Intensifi ed stratifi cation,

Permo–Triassic boundary carbon and mercury cycling linked to terrestrial ecosystem collapse

A new biogeochemical model is built that couples the global Hg and C cycles to evaluate the distinct terrestrial contribution to atmosphere–ocean biogeochemistry separated from coeval volcanic fluxes, and shows that a massive collapse of terrestrial ecosystems linked to volcanism-driven environmental change triggered significantBiogeochemical changes, and cascaded organic matter, nutrients, HG and other organically-bound species into the marine system.

The authors' evidence for widespread photiczone euxinic conditions suggests that sulfide toxicity was a driver of the extinction and a factor in the protracted recovery of the Permian-Triassic superanoxic event.
