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 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.
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 impact at the end of the Cretaceous Period gouged the Chicxulub (pronounced CHIK-shu-loob) crater, 112 miles (180 km) wide and 12 miles (20 km) deep. ... Dinosaurs had long ruled the land but ...
The huge space rock known as the Chicxulub impactor is widely believed to have ended the reign of non-avian dinosaurs, altering the planet's climate and paving the way for mammals to rise from the ...
Location of the Chicxulub Crater on the Yucatan Peninsula of Mexico. 1991. Hildebrand and Boynton declared the Chicxulub Crater to be the result of the impact that triggered the mass extinction at the end of the Cretaceous. [50] Hildebrand and others estimated the diameter of the Chicxulub Crater at 170 kilometers. [39]
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago. Dinosaur-killing asteroid was ...
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.
