Dinosaurs broiled, not grilled

Debris from K-T impact could have been heat source and heat shield

If the dinosaurs didn’t die in a firestorm 65 million years ago, they died in an oven.

New research appearing in the December issue of Geology suggests that the heat from the asteroid impact — blamed for extinguishing most life on the planet at the end of the Cretaceous period — wasn’t enough to ignite worldwide wildfires, as previously thought.
