Quick Answer
In 1991, when geophysicists identified the buried crater in Mexico linked to the dinosaur-killing asteroid impact.
The Full Story
The Chicxulub crater was identified in 1991 through geophysical studies in the Yucatán Peninsula. Scientists recognized its ring-shaped gravity and magnetic signals as evidence of a giant buried impact structure about 180 kilometers wide. The crater is strongly associated with the end-Cretaceous mass extinction 66 million years ago. Its discovery provided a crucial geological link between the impact and global environmental change.
