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 ...
Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium. The impactor likely formed in the outer solar system before migrating to the asteroid belt.
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. ... originate from the asteroid belt. So ...
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.
Keller's research has led her to conclude that the Chicxulub asteroid impact, the leading hypothesized cause for the Cretaceous–Paleogene extinction event, [9] predates the event to the degree that it could not have been the sole cause. "I'm sure the day after, they had a headache," Keller states, further stating that "we vastly overestimate ...
“We found that the impact of an asteroid like the one at Chicxulub is a very rare and unique event in geological time," said researcher Carsten Münker in a statement. "The fate of the dinosaurs ...
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.
