Another asteriod confirmation for the termination dinosaurs

"Until now, though, there hasn’t been enough evidence that the Chicxulub impact actuallycaused the Cretaceous-Paleogene extinction. There was certainly a massive asteroid impact, but previous evidence showed that the asteroid impact occurred up to 300,000 years before the extinction of the dinosaurs. Biologists and geologists have argued that there may have been another cause — an impact at the Shiva crater off the coast of India, global volcanic eruptions, or perhaps something more gradual."
