It seems the demise of the dinosaurs may have been the result of a comet slamming into Earth, not an asteroid.
New research presented this week suggests a fast-moving comet, not an asteroid, caused the extinction of the dinosaurs when it slammed into Mexico’s Yucatan peninsula 65 million years ago. Creating a crater 112 miles wide (180 kilometers), the impact not only killed off non-avian dinosaurs, but also killed 70 percent of all animal species on Earth. Scientists presented their findings at the 44th Lunar and Planetary Science Conference in The Woodlands, Texas.
