Theories attempting to explain it include asteroid or cometary impacts, volcanoes, global climate change, rising sea levels and supernova explosions.Scientists know that at a point about 65 million years ago, some phenomenon triggered mass extinctions on the land and oceans.

She said: 'Not a single species went extinct as a result of the Chicxulub impact.'But Prof Keller does not believe her research, which has taken twenty years, will stop the raging debate at the heart of the demise of the dinosaurs.She said: 'The decades old controversy over the cause of the mass extinction will never achieve consensus.'Understanding what caused the dinosaurs to disappear remains a great mystery.The dinosaurs were wiped out by volcanoes that erupted in India about sixty five million years ago, according to new research.For the last thirty years scientists have believed a giant meteorite that struck Chicxulub in Mexico's Yucatan Peninsula was responsible for the mass extinction of species, including T Rex and its cousins.She said: 'Now we find that another catastrophe, which is Deccan Volcanism, which has not had much attention paid to it, may be the real culprit.'Volcanic eruptions on India's Deccan plateau between 63 and 67 million years ago spewed huge amounts of sulfur dioxide into the air.

The dinosaurs were wiped out by volcanoes that erupted in India about sixty five million years ago, according to new research.

Professor Keller said the meteorite, despite having a diameter spanning six miles, seems to have had no effect on any of the plant and animal life of the region whereas the volcano eruptions could have blocked sunlight, altered climate and caused acid rain.
