Introduction" modelling Late Devonian climates and extinctions Over three decades have passed since McLaren (1970) proposed that the Frasnian/ Famennian (F/F) mass extinction was triggered by an asteroid impact with the Earth, yet still no consensus exists as to the actual cause of the biodiversity crisis (see the reviews of McGhee, 1996; Walliser, 1996). It is generally agreed that the end
- The Late Devonian mass extinction occurred over a wide period of time and has many speculated causes. This event caused 20 % of all families and 50% of all genera to go extinct. Nearly 70% of all invertebrate species, mostly marine dwellers, vanished during this time period.
- The Late Devonian mass extinction, which occurred 374.5 Ma, is one of the ‘Big Five’ mass extinctions in Earth history. Suggested causes of the mass extinction include oceanic anoxia and
- Devonian extinctions, a series of several global extinction events primarily affecting the marine communities of the Devonian Period (419.2 million to 359 million years ago).
- global intervals of mass extinction. Plotted by magnitude, extinction intensities for all Phanerozoic Plotted by magnitude, extinction intensities for all Phanerozoic substages show a continuous distribution, with the ﬁve traditionally recognized mass extinctions
