This paper reviews global records of anoxic events of the Middle Devonian–earliest
Mississippian, as well as the possible triggers and controls of these events. These “anoxic …

The dramatic decline in atmospheric CO2 evidenced by proxy data during the Devonian
(416.0–359.2 Ma) and the gradual decline from the Cretaceous (145.5–65.5 Ma) onwards …

Although the prime causation of the Late Devonian Frasnian–Famennian (F–F) mass
extinction remains conjectural, such destructive factors as the spread of anoxia and rapid …

Abstract The Frasnian-Famennian (FF) global event, one of the five largest biotic crises of
the Phanerozoic, has been inconclusively linked to rapid climatic perturbations promoted in …

Abstract The Late Devonian (383-359 Ma) was a time of prolonged climate instability with
catastrophic perturbation of global marine ecosystems at the Frasnian-Famennian (FF) and …

Widespread oceanic anoxia marked by globally extensive deposition of organic-rich black
shale during the Late Devonian was a major factor in the mass extinctions at the Frasnian …

Abstract The Late Devonian was an epoch of dramatic evolutionary and environmental
changes linked primarily with the Frasnian-Famennian (FF) mass extinction. Current data …

Abstract The Late Devonian envelops one of Earth's big five mass extinction events at the
Frasnian–Famennian boundary (374 Ma). Environmental change across the extinction …
