Our recent PNAS publication on the mechanism of the dinosaur extinction 66 million years ago led to a special article (in Dutch) in the popular journal "Het Laatste Nieuws". We advocate that vaporization by the Chicxulub meteorite impact in Yucatan of large volumes of sulphur-rich rocks caused a major perturbation of the Earth system with darkness and rapid temperature drop. This idea is supported by the total lack of sulphur-rich from the target rock recovered in the recent Chicxulub core drilled by IODP and ICDP.
