Iridium is rare on earth, but plentiful in meteorites. The Alvarez's suggested that a huge asteroid or comet, hit the Earth at that time. The result of such a force would be a gigantic explosion that would throw dust clouds into the sky, darkening the planet. Massive forest fires caused by the hit would also add smoke to the sky. which would then cause climate change ending the dinosaurs rein. As dinosaurs can not keep there body temp. Thats some of the evidence that i am using in my case study about dinosaurs. :-) Hope this helps xx
