More evidence for volcanoes:-http://www.washingtonpost.com/news/speaking-of-science/wp/2014/12/11/did-a-massive-volcanic-eruption-in-india-kill-off-the-dinosaurs/-"Now scientists have found a way to date more precisely the Deccan Traps eruption, and the results are a boost, potentially, for the volcano-did-it camp.-:The main pulse of the lava flow began about 250,000 years before the mass extinction event, and ended about 500,000 years after, according to a paper published online Thursday in the journal Science. Thus if the eruption is not a significant factor in the mass extinction, it's a remarkable coincidence. Earlier attempts to date the Deccan Traps, using less precise methods, had a much larger margin of error, on the order of plus-or-minus one million years."
