An enormous sulfur isotope excursion indicates marine anoxia during the end-Triassic mass extinction

Science Advances, 2020
Low ocean sulfate levels at the end-Triassic mass extinction linked to rapid development of marine anoxia. The role of ocean anoxia as a cause of the end-Triassic marine mass extinction is widely debated.
