The largest extinction was the Kellwasser Event (Frasnian - Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods, and trilobites.
Extinction: The Facts is a 2020 documentary film by the natural historian David Attenborough which aired on the BBC. It depicts the continuing sixth mass extinction, caused by humans, and the consequences of biodiversity loss and climate change. It also suggests positive action which can be taken to halt or reverse these effects.
Permian–Triassic extinction event: 252 Ma Large igneous province (LIP) eruptions [23] from the Siberian Traps, [24] an impact event (the Wilkes Land Crater), [25] an Anoxic event, [26] an Ice age, [27] or other possible causes End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling and ...
The Permian ended with at least one mass extinction, an event sometimes known as "the Great Dying", caused by large floods of lava (the Siberian Traps in Russia and the Emeishan Traps in China). This extinction was the largest in Earth's history and led to the loss of 95% of all species of life. [19] [20]
The climate across the Cretaceous–Paleogene boundary (K–Pg or formerly the K–T boundary) is very important to geologic time as it marks a catastrophic global extinction event. Numerous theories have been proposed as to why this extinction event happened including an asteroid known as the Chicxulub asteroid, volcanism, or sea level changes.
The Late Devonian extinction consisted of several extinction events in the Late Devonian Epoch, which collectively represent one of the five largest mass extinction events in the history of life on Earth. The term primarily refers to a major extinction, the Kellwasser event, also known as the Frasnian-Famennian extinction, [ 1 ] which occurred ...
The Hangenberg event, also known as the Hangenberg crisis or end-Devonian extinction, is a mass extinction that occurred at the end of the Famennian stage, the last stage in the Devonian Period (roughly 358.9 ± 0.4 million years ago).
The Cenomanian-Turonian boundary event, also known as the Cenomanian-Turonian extinction, Cenomanian-Turonian Oceanic Anoxic Event (OAE 2), and referred to also as the Bonarelli Event or Level, [ 2 ] was an anoxic extinction event in the Cretaceous period. The Cenomanian-Turonian oceanic anoxic event is considered to be the most recent truly ...
