Until recently the biotic crisis that occurred within the Capitanian Stage (Middle Permian, ca. 262 Ma) was known only from equatorial (Tethyan) latitudes and its global extent was poorly resolved. The discovery of a Boreal Capitanian crisis in Spits...

The temporal link between large igneous province (LIP) eruptions and at least half of the major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of mass extinction. Here we review almost twenty biotic crises betwee... Read More about On the causes of mass extinctions.
