What happened 65 million years ago?

For decades, scientists have argued over the cause of death of dinosaurs. A new study supports the theory that they ruled volcanoes.

The volcanic activity in the region belonging to India's killed the dinosaurs, say scientists from Princeton University. Scientists, who, for years, I can not decide whether dinosaurs killed volcanoes, meteors, asteroids, or something else entirely.

Scientists at the University of Princeton argue that the huge volcanic eruption in the region known as the "Dean of the Castle" near Mumbai caused toxic pollution of sulfur and carbon dioxide gas that killed the dinosaurs 65 million years ago.

"There's simply no evidence that the Earth was hit by a large enough meteorite or asteroid would cause mass mortality of living beings. Wholly with certainty claim to have done a volcano," said geologist Gerta Keller of Princeton.
