Short answer: The asteroid that triggered the dinosaur extinction struck off the Yucatán Peninsula in Mexico, creating the Chicxulub crater. Latest consensus places the impact there, and studies continue to refine details about the crater’s size and age.

points to the Chicxulub crater, located on the Yucatán Peninsula in Mexico. This crater, partially submerged beneath the ocean, boasts a diameter of approximately 180 kilometers (110 miles), making it one of the largest impact structures on Earth. Its discovery and subsequent analysis provided compelling evidence linking it to the Cretaceous-Paleogene (K-Pg) extinction event, which

Geophysical surveys, using techniques like seismic reflection and gravity measurements, revealed a roughly 180- kilometer-wide circular structure buried beneath layers of sediment. The crater's size, shape, and geological characteristics—including the presence of shocked quartz and other impact-related materials—strongly suggested it was formed by an asteroid impact.
