Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines). The Chicxulub crater (Spanish pronunciation: [t͡ʃikʃuˈlub] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico.
“Modeling studies of the larger Chicxulub impact, which killed off the dinosaurs, also suggest a shift in climate on a much smaller time scale of less than 25 years,” Wade said. “So we still ...
The huge space rock known as the Chicxulub impactor is widely believed to have ended the reign of ... the team searched for isotopes of ruthenium in the geological remnants of the Chicxulub impact ...
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. ...
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.
At the time of the Chicxulub impact, the present-day North American continent was still forming. Most of central North America had recently been a large shallow seaway, called the Western Interior Seaway (also known as the North American Sea or the Western Interior Sea), and parts were still submerged.
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 ...
The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. [10] Its center is located near the town of Chicxulub, after which the crater is named. [11] It was formed by a large asteroid or comet about 10–15 km (6.2–9.3 mi) in diameter, [12] [13] the Chicxulub impactor, striking the Earth. The date of the ...
