- •
Temporal trace metal drawdown suggests a global expansion of oxygen deficiency prior to euxinia.
- •
Modeling Mo drawdown suggest the marine inventory reduction could be biolimiting with <7% euxinia.
- •
Eukaryotic biomarkers contribution decreases during the metal-depleted OAE.
- •
Progressive global deoxygenation and nutrient limitations coincide with known turnover pattern.
