MASSIVE DISRUPTION. “The Great Oxidation Event (GOE) was a time interval when the Earth’s atmosphere and the shallow ocean first experienced a rise in the amount of oxygen. This occurred approximately 2.4–2.0 Ga (billion years ago). The sudden injection of toxic oxygen into an anaerobic biosphere caused the extinction of many existing anaerobic species on Earth. The event is inferred to have constituted a mass extinction.”
