It was, to put it mildly, a bad day on Earth when an asteroid smacked Mexico's Yucatan Peninsula 66 million years ago, causing a global calamity that erased three-quarters of the world's species and ended the age of dinosaurs. Researchers on Monday revealed the potent role that dust from pulverized rock ejected into the atmosphere from the impact site may have played in driving extinctions, choking the atmosphere and blocking plants from harnessing sunlight for life-sustaining energy in a process called photosynthesis. The total amount of dust, they calculated, was about 2,000 gigatonnes - exceeding 11 times the weight of Mt. Everest.
