The Chicxulub crater (Spanish: [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 ]
The Chicxulub impact has been widely considered the most likely cause for the Cretaceous–Paleogene mass extinction, with some scholars linking other impacts like the Popigai impact in Russia and the Chesapeake Bay impact to later extinction events, though the causal relationship has been questioned.
Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth.
By April 1st, a scientific expedition will start drilling into the Gulf's Chicxulub impact crater to study how life recovered following the mass extinction at the end of the Cretaceous period.
After the asteroid that wiped out the dinosaurs hit what is now the Yucatan Peninsula more than 30 million years before these asteroids, its explosive energy resulted in irreversible climate change.
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin.. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium ...
Sudbury Basin is the third-largest crater on Earth, after the 300 km (190 mi) Vredefort impact structure in South Africa, and the 180 km (110 mi) Chicxulub crater under Yucatán, Mexico. Geochemical evidence suggests that the impactor was likely a chondrite asteroid or a comet with a chondritic component.
For example, the Ishim impact structure [141] is conjectured to be bounded by the late Ordovician-early Silurian (c. 445 ± 5 Ma), [142] the two Warburton basins have been linked to the Late Devonian extinction (c. 360 Ma), [310] both Bedout and the Wilkes Land crater have been associated with the severe Permian–Triassic extinction event (c ...
