Permian-Triassic border

The upper layers of the Bellerophon formation mark the Permian-Triassic border, the transition from the Palaeozoic to the early Mesozoic era.
As a result of a catastrophic event, the majority of the flora and fauna of the time died out. New species arose – they can be found as fossils in the Werfen strata which lie above. The precise cause of the mass extinctions is not known (possibly a meteorite collision, a change in the earth’s climate or a change in the maritime currents)
