Sixty-six million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered a mega-earthquake that shook the planet for weeks to months after the collision. The amount of energy released in this mega-earthquake is estimated at 1023 joules, which is about 50,000 times more ...
Researchers from the University of Bath and the Natural History Museum London say that had the impact not happened, dinosaurs might have continued to dominate the Earth. Dinosaurs were widespread globally at the time of the asteroid impact at the end of the Late Cretaceous period, occupying every continent on the planet and were the ...
The beginning of the end caused by a meteor strike started with violent shaking that raised giant waves in the waters of an inland sea in what is now North Dakota. Then, tiny glass beads began to fall like birdshot from the heavens. The rain of glass was so heavy it may have set fire ...
The extinction of woolly mammoths has been a hotly debated topic among scientists, with theories of asteroid collisions, diseases, and human hunting coming up as probable causes. A newly discovered crater in Greenland now gives credence to the idea that the mammoth extinction may have been brought about as a result of an asteroid collision. ...
