Scientists have "traced the origin of the asteroid that hit Earth 65 million years ago, wiping out the dinosaurs."

A related Nature article notes:
Most scientists think that the age of the dinosaurs was doomed when a killer asteroid struck Earth 65 million years ago. But new findings suggest that the giant reptiles may have been destined for death some 100 million years earlier, with the fateful collision of two faraway asteroids.
