INDIAN EXPRESS - Comet, not asteroid, wiped out dinosaurs? Mar 25, 2013

"A speeding comet, rather than an asteroid, slammed into the Earth 65 million years ago and sparked the extinction of the dinosaurs, scientists claim. Many scientists believe the 180 km Chicxulub crater in Mexico was made by the impact that caused the extinction of dinosaurs and about 70 per cent of all species on Earth. The crater was probably blasted out by a faster, smaller object than previously thought, according to the new study presented at the 44th Lunar and Planetary Science Conference in The Woodlands, Texas."
