The death of dinosaurs. La muerte de los dinosaurios

Just many dinosaurs intertwined in desperation.
¨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.
Although the new theory does not completely rule out the effects of such a "nuclear winter," it says the hours just after the 6-mile-wide asteroid struck the Earth were the most critical in the destruction of the dinosaurs.¨
