Stable Isotope Constraints on Marine Productivity Across the Cretaceous‐Paleogene Mass Extinction

Stable Isotope Constraints on Marine Productivity Across the Cretaceous‐Paleogene Mass Extinction

The effects of the Cretaceous-Paleogene (K/Pg) mass extinction (~66 Ma) on marine primary and export productivity remain debated. We studied changes in carbon and nitrogen cycling in eight neritic and upper bathyal sections with expanded K/Pg boundary clay layers in the western Tethys and northeaste...
