252 million years ago, at the transition from the Permian to the Triassic epoch, most of the life forms existing on Earth became extinct. Using latest analytical methods and detailed model calculations, scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel, in cooperation with the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences and international partners, have now succeeded for the first time to provide a conclusive reconstruction of the geochemical processes that led to this unprecedented biotic crisis.
