The time gap between the asteroid impact and the extinction of dinosaurs suggests that it is unlikely animals and organisms were wiped out by a single asteroid collision with our planet, according to a paper published in the current Proceedings of the National Academy of Sciences.

Researchers who recently analyzed the Chicxulub crater near Merida, Mexico, now believe a combination of events, including volcanic eruptions, climate warming, and another asteroid hit closer to the Cretaceous-Tertiary period 65 million years ago, led to the mass extinctions.
