Scientists hit pay dirt in drilling of dinosaur-killing impact crater

Scientists have reached ground zero for one of the world’s most famous cataclysms. Burrowing into the impact structure responsible for the demise of the dinosaurs, a team of researchers has achieved one of its main goals, with rocks brought up from 670 meters beneath the sea floor off the coast of the Yucatán Peninsula in Mexico. These core samples contain bits of the original granite bedrock that was the unlucky target of cosmic wrath 66 million years ago, when a large asteroid struck Earth, blasted open the 180-kilometer-wide Chicxulub crater, and led to the extinction of most life on the planet.
