Oceans lost oxygen 8 million years before end-Triassic mass extinction, study finds

Right out the toaster. Reliable, with some real depth.
Summary
New research reveals that oceans began losing oxygen nearly 8 million years before the end-Triassic mass extinction, not just during the extinction event itself. The study links the deoxygenation to massive volcanic eruptions that warmed the planet, accelerated rock weathering, increased ocean acidity, and created marine dead zones. This earlier-than-expected oxygen loss provides a longer timeline for understanding how warming oceans lead to mass extinction events, and the findings may serve as a warning for modern climate change impacts on ocean health.
