The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo (not to be confused with the larger coastal town of Chicxulub Puerto). [5] It was formed slightly over 66 million years ago when an asteroid, about ten kilometers (six miles) in diameter, struck Earth. The ...
The Chicxulub Crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. It is one of the most significant impact structures on Earth and is associated with the mass extinction event that occurred around 66 million years ago, marking the end of the Cretaceous period and the beginning of the Paleogene period.
The Chicxulub crater is an impact crater located off the Yucatán Peninsula that formed through an asteroid impact about 66 million years ago. The impact and resulting climate change is believed to have led to the mass extinction that wiped out the dinosaurs.
Where did the Chicxulub asteroid that killed the dinosaurs land and what was it made of? Scientists are revealing the secrets of the crater.

Unstable, and under the pull of ...
Illustration: Yucatan Peninsula. Photograph Chicxulub Impact Crater This illustrated image of Mexico's Yucatan Peninsula shows a subtle indication of the Chicxulub impact crater in the upper left. Most scientists now agree that this impact was the cause of the Cretaceous-Tertiary Extinction, the event 65 million years ago that marked the sudden extinction of the dinosaurs, as well as the ...
Chicxulub Impact Breccia The discovery of shocked quartz, shocked feldspar, and impact melts in the Yucatán-6 exploration borehole from the interior of the Chicxulub structure, proved it was an impact crater and that it was produced at the Cretaceous-Tertiary (K-T) boundary. This is a photograph of one of the two samples behind that discovery. The sample is a polymict breccia recovered from a ...
The Impact - Kill Hypothesis The Cretaceous-Tertiary boundary (KTB) mass extinction is primarily known for the demise of the dinosaurs, the Chicxulub impact, and the frequently rancorous thirty years-old controversy over the cause of this mass extinction. Since 1980 the impact hypothesis has steadily gained support, which culminated in 1990 with the discovery of the Chicxulub crater on Yucatan ...
