A new study has suggested that volcanic activity was responsible for wiping out the dinosaurs.
What caused the dinosaurs to go extinct 65 million years ago remains one of the most debated topics in science. The most commonly accepted explanation is that a large asteroid hit the Earth around that time, but not everyone subscribes to this idea. New research in to the events that lead to the dinosaurs' demise has suggested that volcanoes may have been to blame, spewing high levels of poisonous gases in to the atmosphere and turning the sea in to an acidic soup.
The activity would have been centered around the Deccan Traps, a region of intense volcanism located in what is now modern day India. "Our new information calls for a reassessment of what really caused the K-T mass extinction," said study author Gerta Keller. At the very least it is believed that volcanic activity would have been a contributing factor in the dinosaurs' destruction.
"The findings, presented Wednesday (December 5) here at the annual meeting of the American Geophysical Union, are the latest volley in an ongoing debate over whether an asteroid or volcanism killed off the dinosaurs about 65 million years ago in the mass die-off known as the K-T extinction."
