Theory on Dinosaurs and Volcanic Activity 65 Million Years Ago - New York Times

Theory on Dinosaurs and Volcanic Activity 65 Million Years Ago - New York Times: By HENRY FOUNTAIN (NYT)

A new analysis lends support to the idea that massive volcanic activity around 65 million years ago may have played a roll in wiping out the dinosaurs. "The volcanic activity over thousands of years produced a flood of lava, now known as the Deccan Trapps, that is thousands of feet thick over thousands of square miles of central India. The researchers’ analysis, reported in Science, suggests the eruption could have produced on the order of 30 billion pounds of sulfur dioxide and 9 billion pounds of hydrogen chloride for each cubic mile of lava."
