Short summary
Middle–Late Devonian sedimentary rocks are often punctuated by anoxic black shales. Due to their semi-regular nature, anoxic events may be linked to periodic changes in the Earth’s climate caused by astronomical forcing. We use portable X-ray fluorescence elemental records, measured on marine sediments from Germany, to construct an astrochronological framework for the Kellwasser ocean anoxic Crisis. Results suggest that the Upper Kellwasser event was preceded by a specific orbital configuration.
