Theory regarding the causation of mass extinctions is in need of systematization, which is
the focus of this contribution. Every mass extinction has both an ultimate cause, ie the trigger …

Abstract The global Hangenberg Crisis near the Devonian–Carboniferous boundary (DCB)
represents a mass extinction that is of the same scale as the so-called 'Big Five'first-order …

Icehouses are the less common climate state on Earth, and thus it is notable that the longest-
lived (c. 370 to 260 Ma) and possibly most extensive and intense of icehouse periods …

The Paleozoic emergence of terrestrial plants has been linked to a stepwise increase in
Earth's O 2 levels and a cooling of Earth's climate by drawdown of atmospheric CO 2 …

Milankovitch cycles are quasi-periodic fluctuations in insolation forced by variations in the
Earth's astronomical parameters, inducing climate change, and in turn affecting …

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 …

There is an unexplained terrestrial mass extinction at the Devonian-Carboniferous boundary
(359 million years ago). The discovery in east Greenland of malformed land plant spores …

Abstract The Devonian–Carboniferous transition marks a fundamental shift in the surface
environment primarily related to changes in ocean–atmosphere oxidation states,, resulting …

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 …

The Late Devonian was a protracted period of low speciation resulting in biodiversity
decline, culminating in extinction events near the Devonian–Carboniferous boundary …
