The Chicxulub crater (Spanish pronunciation: [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 ]
They left miles-long craters in the Mid-Atlantic Chesapeake Bay and Siberia: the fourth- and fifth-largest asteroid craters on Earth. ... “Modeling studies of the larger Chicxulub impact, which ...
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 ...
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 ...
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.
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.

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.
In 2016, a scientific drilling project drilled deep into the peak ring of the Chicxulub impact crater to obtain rock core samples from the impact itself. This crater is one of the best known impact craters and was the impact responsible for the extinction of the non-avian dinosaurs. The discoveries were widely seen as confirming current ...
