What happened

New research contradicts popular theory that a nuclear winter wiped out the dinosaurs See more of our coverage in your search results.

Why it matters

Add The New York Post on Google Scientists have long speculated that the demise of the dinosaurs some 66 million years ago was due to starvation triggered by a nuclear winter that followed a major asteroid impact.

Common ground

However, disturbing new research suggests the prehistoric megadeath may have come quicker and burned hotter.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
