The Chicxulub crater on the Yucatan peninsula is believed to be the most likely site of the asteroid impact responsible for the demise of the dinosaurs. The crater measures between 180 and 240 kilometres across, indicating an impactor of colossal size, the biggest impact confirmed on Earth. Chicxulubkratern (uttalas "tjick-schu-'lubb") är en uråldrig nedslagskrater, ett så kallat astroblem, som ligger begravd under Yucatánhalvön i Mexiko.Dess mittpunkt ligger ungefär under orten Chicxulub. The precise size and morphology of the Chicxulub crater has been in dispute; it has been interpreted as a ∼ 180 km peak-ring crater 2, 9, 11, a ∼ 250 km peak-ring crater 5, 8, and a ∼ 300 km Size and morphology of the Chicxulub impact crater Morgan, Jo Warner, Mike CHICXULUB Working Group Brittan, John Buffler, Richard Camargo, Antonio Christeson, Gail Denton, Paul Hildebrand, Alan Hobbs, Richard MacIntyre, Hamish MacKenzie, Graeme Maguire, Peter Marin, Luis Nakamura, Yosio Pilkington, The size of the Chicxulub crater, YucatBn, M6xico is currently in dispute with diameter estimates ranging from 170 km upwards of 300 km (1,2,3). These size estimates have been largely based on the shape of the Bouguer gravity anomaly over the crater (1, 2) and the distribution of fractures inferred from the cenotes (sinkholes) in the region (3). Here we show the diameter of the crater to be ~180 km by examining the horizontal gradient of the Bouguer gravity anomaly over the structure.

Scientists have found space dust in Chicxulub crater, which provides evidence that the asteroid impact and dinosaur extinction are “indisputably linked”. Some 66 million years ago, dinosaurs on Earth were wiped out, and a growing body of researchers supports the theory that the main culprit was an asteroid impact in what is present-day Mexico as against the theory that volcanism in Deccan Size isn't the only thing that makes Chicxulub special. Most scientists now agree it's the "smoking gun" -- evidence that a huge asteroid or comet indeed crashed into Earth's surface 65 million years ago causing the extinction of more than 70 percent of the living species on the planet, including the dinosaurs. 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.

The “Chicxulub impactor,” which left a crater off the coast of Mexico that spans 93 miles wide and 12 miles deep, was “roughly the size of Boston,” astronomer Avi Loeb says in the video above. READ MORE: Johnson & Johnson COVID Vaccines Paused As CDC, FDA Investigate Rare Blood Clots 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. After examining the crater size, the meteoritic content for mass, and the impact models for velocity, researchers find indications to believe that the Chicxulub crater was formed by a short period comet or an asteroid impact that released 0.7-3.4 × 10 31 ergs of energy.

IT is now widely believed that a large impact occurred on the Earth at the end of the Cretaceous period, and that the buried Chicxulub structure in Yucatán, Mexico, is the resulting crater²⁴. Knowledge of the size and internal structure of the Chicxulub crater is necessary for quantifying the effects of the impact on the Cretaceous environment. Although much information bearing on The Chicxulub crater in Mexico 2, 3, 4, 5, 6, 7, which is the largest known Phanerozoic impact structure, is now widely accepted as the site of this event. The crater is located partly offshore; It appears to have a diameter of 145 to 180 km, which makes it one of the largest confirmed impact structures on Earth.

Chicxulub is the only known Earth crater with a remaining impact peak ring, but it is under 600 m (2,000 ft) of sediment. During April and May 2016, a joint IODP - ICDP [79] [80] Mission Specific Platform Expedition no. 364 obtained the first offshore core samples from the peak ring, surrounding the central zone of the crater. [81] About The Chicxulub Crater. The Chicxulub crater on the Yucatan peninsula is believed to be the most likely site of the asteroid impact responsible for the demise of the dinosaurs. The crater measures between 180 and 240 kilometres across, indicating an impactor of colossal size, the biggest impact confirmed on Earth.
