Abstract

The course of the biotic recovery after the impact-re[ated disruption of photosynthesis and mass extinction event at the Cretaceous-Pa[eogene boundary has been intense[y debated. The resurgence of marine primary production in the aftermath remains poor[y constrained because of the paucity of fossil records tracing primary producers that [ack skeletons, Here we present a high-reso[ution record of geochemica[ variation in the remarkably thick Fiske[er (a[so known as the Fish C[ay) boundary [aver at Ku[stirenden, Denmark. Converqinq evidence from the stab[e isotopes of carbon and nitrogen and abundances of a[ga[ steranes and bacterial hopanes indicates that a[ga[ primary productivity was strongly reduced for on[y a brief period of possib[y less than a century after the impact, fo[[owed by a rapid resurgence of carbon fixation and eco[ogica[ reorganization.
