SCI/TECH: A Fiery Death for Dinosaurs?

A Fiery Death for Dinosaurs?
In the first few hours after a giant asteroid crashed into the coast of Mexico nearly 65 million years ago, the Earth's atmosphere became so hot that it quickly incinerated any unprotected life on land, according to a new report by a team of American geophysicists and geologists.

The report, which appears in the May-June issue of the Bulletin of the Geological Society of America, contradicts the widely accepted theory that the dinosaurs died out over a period of months or years after the asteroid impact at Chicxulub, Mexico. Under that theory, the asteroid impact would have thrown enough dust into the atmosphere to block out the sun, leading to a cold, dark winter that directly reduced the amount of plant life on Earth.
