What are 3 pieces of evidence that supports why dinosaurs became extinct due to a comet?
There is strong evidence that an extraterrestrial object impacted near the Yucatan peninsula. There is also evidence that a boundary layer was formed that is rich in iridium. The most plausible origin of this iridium is an extraterrestrial impact. Below that layer, dinosaur bones are present and above that zone there are none. If I had to bet, I'd bet that the comet killed them by the effects of the impact.
