DOIAbstract
International audienceThe Cretaceous-Paleogene boundary ~65.5 million years ago marks one of the three largest massextinctions in the past 500 million years. The extinction event coincided with a large asteroidimpact at Chicxulub, Mexico, and occurred within the time of Deccan flood basalt volcanism inIndia. Here, we synthesize records of the global stratigraphy across this boundary to assess theproposed causes of the mass extinction. Notably, a single ejecta-rich deposit compositionally linkedto the Chicxulub impact is globally distributed at the Cretaceous-Paleogene boundary. Thetemporal match between the ejecta layer and the onset of the extinctions and the agreement ofecological patterns in the fossil record with modeled environmental p...
