12 Nov 2018 Chicxulub Puerto, Mexico, is the centre of the impact crater that scientists believe was made when the asteroid that wiped out the dinosaurs 


2021-02-27 · An iridium anomaly found globally at the end-Cretaceous mass extinction horizon was discovered in new core samples from within the Chicxulub impact crater. That anomaly is shown here with a picture of the analyzed core sample that contains debris that settled through the post-impact atmosphere. Data from Goderis et al. (Science Advances, 2021).

We present a detailed record of molecular burn markers (polycyclic aromatic hydrocarbons [PAHs]) from the Chicxulub crater and in ocean sediments distant from the impact site #ScientiFixSpace dust in the 66 million year-old crater on Earth, what sets the mood for moths & more -- Watch this episode of #ScientiFix with ThePrint’s Mo More than 3,000ft of rock core samples taken from below the Chicxulub crater in the Gulf of Mexico and they included evidence of asteroid dust, proving a space rock impact killed the dinosaurs. The Chicxulub impactor (/ ˈ tʃ iː k ʃ ə l uː b / CHEEK-shə-loob), also known as the K/Pg impactor or (more speculatively) as the Chicxulub asteroid, was the asteroid or other celestial body that struck Earth about 66 million years ago, creating the Chicxulub crater and, according to scientific consensus, acting as the main cause of the Cretaceous–Paleogene extinction event. More information: Shelby L. Lyons et al. Organic matter from the Chicxulub crater exacerbated the K–Pg impact winter, Proceedings of the National Academy of Sciences (2020). DOI: 10.1073/pnas The Chicxulub impactor was an asteroid or comet that crashed into Earth about 66 million years ago and left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep.

Satellite images showing a necklace of sink holes, called cenotes, across the Yucatan's northern tip are what first caught the attention of NASA researchers Drs. Kevin Pope, Adriana Ocampo and Charles Duller in 1990. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end, scientists say, by triggering their sudden mass extinction, along with the end of New evidence found in the Chicxulub crater suggests the black carbon that filled the atmosphere after an asteroid struck Earth 66 million years ago was caused by the impact and not massive wildfires. The Chicxulub crater, which is located half under the sea and half on land, is now buried under sediment up to 600m in depth. The impact that formed the Chicxulub crater would have had a catastrophic effect on the entire Earth for many years.

Chicxulub crater from space

Location: Yucatán, Mexico. Specs: Located on the Yucatán Peninsula in Mexico, many scientists believe that the meteorite This shaded relief image of Mexico's Yucatan Peninsula show a subtle, but unmistakable, indication of the Chicxulub impact crater. Most scientists now agree that this impact was the cause of the Cretatious-Tertiary Extinction, the event 65 million years ago that marked the sudden extinction of the dinosaurs as well as the majority of life then on Earth.
