The Chicxulub crater (IPA: [t͡ʃikʃuˈlub] ⓘ cheek-shoo-LOOB) 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 the larger coastal town of Chicxulub Puerto). [3]

However, in 1991, scientists found that the Chicxulub crater was the right age to have been formed by a massive asteroid strike coinciding with the demise of the dinosaurs.
Chicxulub Crater is an ancient impact crater buried underneath the Yucatán Peninsula, with its center located near the town of Chicxulub, Yucatán, Mexico.The crater is over 180 kilometers (110 mi) in diameter, making the feature one of the largest confirmed impact structures in the world; the asteroid or comet whose impact formed the crater was at least 10 km (6 mi) in diameter.
In this dramatic illustration, a meteor falls toward Earth from space. A pair of asteroids that rammed into Earth more than 35 million years ago seemingly had no climate impacts, scientists said ...
Evidence at the Chicxulub crater supports the notion that the crash would have been devastating enough to send deadly vaporized rock and gas into the atmosphere, filling the Earth with dust ...
Further research identified the giant Chicxulub crater, buried under Chicxulub on the coast of Yucatán, as the source of the K–Pg boundary clay. Identified in 1990 [14] based on work by geophysicist Glen Penfield in 1978, the crater is oval, with an average diameter of roughly 180 km (110 mi), about the size calculated by the Alvarez team.
The trajectory of the Chicxulub asteroid led to the most efficient release of gas and projectile rocks – which was disastrous for life on Earth. Dinosaur-killing asteroid struck at worst angle ...
