Global ocean redox changes before and during the Toarcian Oceanic Anoxic Event [PDF]
Nature Communications, 2023 Geochemical modeling shows that just a several percent expansion of O2-free areas with toxic sulfide build-up likely contributed to biodiversity loss or reorganization during the Toarcian mass extinction 183 million years ago.

Charcoal evidence that rising atmospheric oxygen terminated Early Jurassic ocean anoxia [PDF]
Nature Communications, 2017 Numerical models predict that during an oceanic anoxic event (OAE), increased organic carbon burial drives a rise in atmospheric oxygen leading to the event’s termination. Here, the authors present evidence suggesting that the Toarcian OAE was terminated

Evidence for the early Toarcian Carbon Isotope Excursion (T-CIE) from the shallow marine siliciclastic red beds of Arabia [PDF]
Scientific Reports, 2022 The Toarcian Oceanic Anoxic Event (T-OAE) and its corresponding Carbon Isotope Excursion (CIE) have been reported widely across the Tethyan region and globally.

Ocean acidification at the Toarcian Anoxic Event captured by boron isotopes in the lime mud record [PDF]
Communications Earth & EnvironmentThe Toarcian Oceanic Anoxic Event (ca. 183 million years ago) marks a global mass extinction coincident with dramatic changes in climate and ocean circulation, likely driven by large igneous province emplacement.

Ocean warming affected faunal dynamics of benthic invertebrate assemblages across the Toarcian Oceanic Anoxic Event in the Iberian Basin (Spain). [PDF]
PLoS ONE, 2020 The Toarcian Oceanic Anoxic Event (TOAE; Early Jurassic, ca. 182 Ma ago) represents one of the major environmental disturbances of the Mesozoic and is associated with global warming, widespread anoxia, and a severe perturbation of the global carbon cycle.
