The Chicxulub Asteroid Did Not Just Kill Dinosaurs - It Triggered a Chain of Events That Reshuffled Every Ecosystem on Earth and Made Mammals the Dominant Life Form

The Chicxulub Asteroid Did Not Just Kill Dinosaurs – It Triggered a Chain of Events That Reshuffled Every Ecosystem on Earth and Made Mammals the Dominant Life Form

If you still picture the dinosaur apocalypse as a single bad day with one unlucky T. rex staring at a fireball, you’re wildly underestimating how dramatic that event really was. The Chicxulub impact was less a moment and more a reset button, a violent reboot that rewrote the rules of life on Earth and quietly ...

A Second Impact Crater Has Been Discovered Beneath the Ice of Greenland That May Have Struck Earth Around the Same Time As the One That Killed the Dinosaurs

A Second Impact Crater Has Been Discovered Beneath the Ice of Greenland That May Have Struck Earth Around the Same Time As the One That Killed the Dinosaurs

Sixty-six million years ago, a space rock slammed into what is now Mexico and helped wipe out the dinosaurs. That story has become almost mythic at this point. But now imagine this: while that famous crater was forming, another huge object may have hit Earth near the very top of the globe, in what is ...

Scientists Have Now Identified the Exact Source Region in the Asteroid Belt Where the Dinosaur-Killing Rock Came From and the Implications Are Uncomfortable

For decades, the rock that erased almost all dinosaurs was like a cosmic hit‑and‑run: we knew the crater, we knew the time, but we did not really know who sent the killer. Now, that picture is changing fast. By combining asteroid surveys, impact modeling, and geochemical sleuthing, researchers have zeroed in on a specific swath ...
