The Chicxulub crater in Yucatan (Mexico) is what remains from the dinosaur extinction event. Now featured on a coin! Ultra deep crater, coloring, glass inlay, antique finish, meteorite inlay. 3oz pure silver with just a 333 tiny mintage. The Chicxulub crater is an impact crater buried underneath the Yucatan Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth. The date of the impact coincides precisely with the Cretaceous Paleogene boundary, slightly less than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from the event was the cause of the Cretaceous Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs.
