Paleogeography and paleoenvironments of the Late Devonian Kellwasser event: A review of its sedimentological and geochemical expression
Abstract The Late Devonian (383-359 Ma) was a time of prolonged climate instability with
catastrophic perturbation of global marine ecosystems at the Frasnian-Famennian (FF) and …
