Chicxulub Impact Breccia. A … The Chicxulub crater marks the point of contact made by an asteroid so enormous that it wiped out an entire planet’s worth of dinosaurs. A few minutes later, a layer of melting rock approximately 131 feet (40 meters) spilled out as overflow. The Chicxulub crater off the coast of Mexico’s Yucatán Peninsula has preserved the details of what led to the extinction of most life on Earth millions of years ago, and it is the only crater … Description. The Chicxulub Crater is one of the largest impact craters on Earth, the only one with an unequivocal peak ring, and the only one linked to a mass extinction. Some cenotes are small and shallow but others are very large and deep. 65 million years ago, a massive asteroid crashed into Mexico's Yucatan Peninsula — a site now known as the Chicxulub Crater. It was identified from a nearly circular gravity anomaly along the northwestern edge of the Yucatán Peninsula (Figure 1). The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on Earth. Extraordinary rocks from the peak ring of the Chicxulub impact crater: P-wave velocity, density, and porosity measurements from IODP/ICDP Expedition 364. 1) The Chicxulub Impact Crater, is a geomorfological formation dating from the end of the Mesozoic era, specifically by the end of the Cretaceous at the limits with the Terciary, that was produced by the impact of a meteorite. Chicxulub Crater Science Museum Posted on December 1, 2019 December 1, 2019 by ProgresoVida One interesting place nearby is the Chicxulub Crater Science Museum , which is near Progreso but, oddly enough, not actually located in Chixculub or Chixculub Puerto (though it is well within the crater). The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on Earth.

This cataclysmic event that triggered a world-wide tsunami and disrupted global climates has been linked to the extinction of the dinosaurs and up to 75% of all other life. Yet now experts have dug deep into the massive cavity, and they’ve finally realized precisely what occurred when the space rock actually struck the Earth. A cenote is a natural hole in limestone bedrock -- a sinkhole -- with water at the bottom of it. In just a few seconds, the 112-mile wide crater formed. The Chicxulub crater isn’t visible on the surface because it is covered by younger, relatively undeformed sediments.
