The end of the dinosaurs the sad thing to know but it’s also the thing that possibly allowed humans to evolve so seeing what a T-rex looks like would be a bad idea unless the T-rex was tamed then it wouldn’t harm you but I think you can’t tame a T-rex. (theory 1) The famous meteorite was huge but tiny to the earth so how did it do so much damage well the meteor itself meteor was approximately as big as Mount Everest and it would have created earth quakes and may be tsunamis. A meteorite with the power of a dooms day device ,the shake would have set off lots of volcano’s there would have been acid showers and painful deaths ash and more falling to the ground water that was drowning many creatures it was terrible if you were there you would have been killed.
