Buried underneath the Yucatan Peninsula in Mexico lies the Chicxulub crater, a 66 million year old impact crater formed by an asteroid or comet thought to be anywhere from 6 to 50 miles in diameter. Debris from the explosion was thrown into the atmosphere, putting chemicals in the air and soil, severely changing the climate. It is hypothesized that this event triggered megatsunamis, earthquakes, and volcanoes, leading to the extinction of 75% of the species that existed at that time.
