Permian-Trassic extinction event 252 mya

Shortly after Pangaea assembled 96% of all marine species and 70% of all terrestrial vertebrate species (~76 % of genera) become extinct during the Permian-Trassic extinction event. Most probably as a result of the climatic disturbances associated with the eruption of the Siberian Traps large igneous province (http://en.wikipedia.org/wiki/Siberian_Traps).
