The extinction of the dinosaurs spread out within ka with major extinction beginning at the boundary interval. This is even later than their extinction in Montana, North America and in India. Successive short- and long-term conditions of geochemically induced environmental stress negatively affected the reproductive process and thus contributed to the extinction of the dinosaurs.
