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.
Unprecedented global warming will wipe out all mammals during a mass extinction event in about 250 million years, according to a new study.. The world’s continents are predicted to eventually ...
