Chicxulub crater
Chicxulub is most famous for being near the geographic center of the Chicxulub crater, an impact crater discovered by geologists on the Yucatán Peninsula and extending into the ocean. It was created by the impact some 66 million years ago of the Chicxulub impactor, an asteroid or comet which caused the Cretaceous–Paleogene extinction event, which led to the extinction of all non-avian dinosaurs. The coastal village (or "puerto") of Chicxulub, in the neighboring municipality of Progreso, lies almost exactly on the geographic center of the crater.
