Some 65 million years ago dinosaurs were wiped out from the planet Earth. But, what factors are responsible for this mass extinction of the giant creatures? This issue has been kicking up controversies since ages, and is seemingly a never-ending one.

Efforts to identify the phenomenon is being confused by evidence of massive volcanic activity in India at the same time, and a fossil record suggesting dinosaurs might have disappeared gradually as the Earth’s climate and geology changed over millions of years, according to a report by London Telegraph.

A paper written by Peter Schulte of the University of Nuernberg and colleagues in the journal Sedimentary Geology has kicked up the controversy. They say two cores drilled in Brazos, Texas, provide support for the asteroid-impact theory.
