The Chicxulub impact brought an end to one of Earth's great eras before the planet entered its Ice Age, which lasted until the Cenozoic era arrived.

"But as you can see, this meteorite is supposed to be bigger, so much bigger than the Chicxulub meteorite, which created an era when life was off limits. This meteorite, therefore, should have started an era when life was nearly extinct a longer period of time, and possibly even destroyed all life on earth!"
