CHAMPAIGN, Ill. — Two of the three largest impact craters on Earth have nearly the same size and structure, researchers say, but one was caused by a comet while the other was caused by an asteroid.

Thanks to decades of collaboration between geologists, paleontologists, meteorologists, and astronomers, we possess a fairly confident timeline of when and how dinosaurs' Earthly reign was cut short.

The Chicxulub Crater is located off the Yucatán Peninsula in Mexico and is believed to be caused by an asteroid 66 million years ago that measured six miles wide. The impact was catastrophic for life ...
