Oceanic anoxic events are geologically abrupt phases of extreme oxygen depletion in the oceans that disrupted marine ecosystems and brought about evolutionary turnover. Typically lasting approximately 1.5 million years, these events occurred frequently during the Mesozoic era, from about 183 to 85 million years ago. One hypothesis suggests that anoxic events resulted from enhanced chemical weathering of Earth’s surface in a greenhouse world shaped by high volcanic carbon outgassing. Gernon et al. tested this hypothesis using a combination of plate reconstructions, tectonic-geochemical analysis and global biogeochemical modeling. Image credit: University of Southampton.
