An Ancient, Massive Impact Crater in Yucatan

There is evidence of an ancient, hidden crater in the a yucatan peninsula. The impact has been dated to around 66 million years ago and we know what happened at that time - the extinction event of the non alien dino. It was a massive extintion event. I think it's five million times five million times the energy of the hiroshima atomic mob. That was the energy released by this enormous eteterrestrial impact. So it clearly caused a global catastrophe.
