Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines). The Chicxulub crater (Spanish: [t͡ʃikʃuˈlub] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico.
The location of the impact was unknown when the Alvarez team developed their hypothesis, but later scientists discovered the Chicxulub Crater in the Yucatán Peninsula, now considered the likely impact site. [4] Badlands near Drumheller, Alberta where erosion has exposed the K–Pg boundary.
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.
An animation modelling the impact, and subsequent crater formation of the Chicxulub impact (University of Arizona, Space Imagery Center) The prehistoric Chicxulub impact , 66 million years ago, believed to be the cause of the Cretaceous–Paleogene extinction event, was caused by an asteroid estimated to be about 10 kilometres (6.2 mi) wide.
The impactor likely formed in the outer solar system before migrating to the asteroid belt. A team of researchers think they know the origin of a massive space rock that hit Earth and killed off ...
The following tables list geological features on Earth that are known impact events as well as possible, but for which there is currently no confirming scientific evidence in the peer-reviewed literature, impact events. In order for a structure to be confirmed as an impact crater, it must meet a stringent set of well-established criteria. Some ...

Chicxulub Pueblo (Mayan pronunciation: [tʃʼikʃuluɓ] Ch’ik Xulub) is a town, and surrounding municipality of the same name, in the Mexican state of Yucatán. At the census of 2010, the town had a population of 4,080 people. The center of the Chicxulub Impact Crater (approx 21°20'N 89°30'W) is off the Yucatan coast, near Chicxulub Puerto
