For decades, the disappearance of dinosaurs has been tied to the Chicxulub asteroid, whose crater lies partly beneath Mexico’x Yucatan Peninsula. But new research has revealed that there were at ...

The Chicxulub crater, located off the coast of the Yucatán Peninsula in Mexico, is one of the most significant geological sites on Earth. It marks the catastrophic impact of a massive asteroid or ...

Though an interesting read, and a compelling case, it lacked a little something; an impact crater. It would take another 10 years before samples from the Chicxulub crater were studied by Penfield.

Approximately 66 million years ago, the Chicxulub asteroid, estimated to be 10-15 kilometer in diameter, struck the Yucatán Peninsula (in current-day Mexico), creating a 200-kilometer-wide impact ...

The 5.3-mile-wide crater is now confirmed to be 66 million years old, suggesting that the impact of at least two giant space rocks preceded the mass extinction of dinosaurs.
