New Study Reveals Second Asteroid Contributed to Dinosaur Extinction

Researchers have identified a second crater off West Africa's coast, suggesting another asteroid hit Earth around the same time as the Chicxulub impact.

The Nadir Crater, located beneath the Atlantic Ocean near Guinea, was formed by an asteroid impact 66 million years ago.
High-resolution 3D seismic data confirmed the crater's formation from a 450-500 meter wide asteroid.
The impact likely caused a massive tsunami over 800 meters high across the Atlantic Ocean.
Scientists are exploring the possibility of multiple asteroid impacts contributing to the end-Cretaceous extinction event.
This discovery offers unprecedented insights into marine impact craters and their formation processes.
