Oceanic anoxic events, photic-zone euxinia, and controversy of sea-level fluctuations during the Middle-Late Devonian
This paper reviews global records of anoxic events of the Middle Devonian–earliest

Major Early-Middle Devonian oceanic oxygenation linked to early land plant evolution detected using high-resolution U isotopes of marine limestones
Abstract The middle Paleozoic (∼ 420-350 Myr) records a major increase in ocean-

Atmosphere–ocean oxygen and productivity dynamics during early animal radiations
TW Dahl, JN Connelly, D Li… - Proceedings of the …, 2019 - National Acad Sciences
The proliferation of large, motile animals 540 to 520 Ma has been linked to both rising and
declining O2 levels on Earth. To explore this conundrum, we reconstruct the global extent of …
