Ocean Oxygenation and the End-Cretaceous Mass Extinction
Z. Rao, Y. Liu, E. Kast, T. Westerhold et autres
The Cretaceous/Paleogene (K/Pg) mass extinction significantly perturbed the marine environment and the global carbon cycle. We provide new constraints on ocean oxygen and biogeochemical changes across the K/Pg boundary, combining records of foraminifera-bound organic matter nitrogen isotopes (FB-δ15N) and simulations from a …
