Unveiling the Deadly Impact: How Asteroid Dust Led to the Extinction of Dinosaurs
TL;DR Summary
New research suggests that the extinction of dinosaurs 66 million years ago was caused by an asteroid impact that kicked up a massive amount of dust into the atmosphere. Previous theories proposed that sulfur or soot caused an impact winter, but the study based on particles found at a fossil site supports the hypothesis that fine silicate dust from the asteroid stayed in the atmosphere for 15 years, causing a drop in global temperatures and a catastrophic collapse of life. Understanding past mass extinctions is crucial for predicting future ones.
