Did volcanoes kill the dinosaurs ?

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."

Well damn. I suppose I will have to replan my whole trip nao. FFS. Okay so purchase a rocket launcher and other peace offerings. Gotcha. Did I mention I am allergic to walnuts? Maybe I should have in my introduction post.... You just stay over there, I don't want any trouble.

I suggest if you want to use a time machine I would go forwards instead of back. You can name any period of Earth history and none of them are stable. In the Middle Ages and the Stuart period you could be condemned as a witch just for using a time machine. If your really lucky you might end up a serving wrench provided your not burned at the stake. I know it dosn't paint a pretty picture but tbh it would be better if you stay where you are. I'm as curious about the dinosaurs as you but we'll just have to use our imagination atm. You don't need to worry about me. I'm no tr... [More]

Can't I just go for like an hour? Actually, forget it. I am extremely clumsy, my luck I'll hit the wrong button on that damn thing and it will send me into the ice age. I'm not a fan of cold **** (stuff). too afraid of the future to even look really... I'll stay here in my warm bed and look at pictures of dinosaurs. You talked me into it.

Some alien species have killed them and these aliens tried to make their living here on Earth but failed. Because these aliens soon realized that there were thousands of living organisms here that they cannot adopt with. Hmmm, my story I think is more credible than these scientist. So wait for my book.

True science has had many theories but the asteroid impact seems to be the theory that is most widely accepted. Now it would seem science is having second thoughts. It wouldn't surprise me if they change their minds on the Big Bang that created the universe.

I`m incline to think both, I guess you can`t have a massive asteroid hit with out setting off a few volcanos.

The eruption of the Deccan traps has been dated to the right time for the KT extinction. The eruption of the Siberian traps occured at around the same time as the end-Permian extinction. There's long been debate about what killed off the dinosaurs. You've got two major events occurring around the same time. Either one, or a combination of both, could have been enough. The general consensus though is that it was the Chicxulub impact that had the most profound effect.

I think it was the date. 21 December 2 (add your own zeroes) and 12.
