Extinction Level Event - Impact Winter
At the end of the Cretaceous Period, 66 million years ago, the impact of a massive asteroid with the Earth resulted in billions of tons of dust and particles being ejected into the atmosphere. This lead to a serious decline in photosynthesis and a drastic decrease in temperature due to the blockage of the sun's radiation. It has been suggested that this could have caused an impact winter that froze large areas of the Earth. It is now generally accepted that the global catastrophe due to the impact of the asteroid lead to the mass extinction of 75% of the Earth's species, including all the non-avian dinosaurs.
