Scientists Agree Asteroid Killed Dinos

After two decades of dino debate, the results are in. In an "international consensus," a panel of "blue-ribbon" scientists have decided the Chicxulub asteroid-impact crater located in Mexico's Yucatan Peninsula was, indeed, the cause of the mass extinction occurring 65 million years ago, wiping out the dinosaurs and the majority of life on Earth. An international group of more than three dozen scientists reported an unquestionable link between the Chicxulub impact event and the K-T boundary mass extinction. The initial discovery of the crater's significance happened in 1991, with the debate finally laid to rest this week.
