Impactors strike during the reign of the dinosaurs (image credit: MasPix/devianart)
For decades scientists have believed that an asteroid impact event ended the era of the dinosaurs 66 million years ago. Now, analysis from the crater site itself seals the deal: the same elements that were deposited around the world from the impact have been found inside the crater itself.

Everyone knows an asteroid strike wiped out the dinosaurs, right? Lots of evidence shows that the Chicxulub impact event had terrible consequences for the dinosaurs. But the picture is a little more complicated than that. Extreme volcanic activity may have contributed to the extinction.
