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]
Meanwhile, the samples taken from the Cretaceous-Paleogene (K-Pg) boundary, where the Chicxulub impactor hit, suggested that the object was a C-type asteroid, which typically live in the outer ...
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.
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. ... "I think without this cosmic ...
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. [6]
However, the most widely accepted theory for the mass extinction is that an asteroid (or, perhaps a comet) at least 10 kilometers in diameter crashed near modern-day Chicxulub on the Yucatán ...
In March 2010, an international panel of scientists endorsed the asteroid hypothesis, specifically the Chicxulub impact, as being the cause of the extinction. A team of 41 scientists reviewed 20 years of scientific literature and in so doing also ruled out other theories such as massive volcanism.
Fine dust thrown up into Earth’s atmosphere after an asteroid strike 66 million years ago blocked the sun to an extent that plants were unable to photosynthesize, a new study has found.
