Uniquely, Tanis appears to record in detail, extensive evidence of the direct effects of the giant Chicxulub asteroid impact which struck the Gulf of Mexico 66.043 million years ago, and wiped out all non-avian dinosaurs and many other species (the so-called "K–Pg" or "K–T" extinction).
Location of the Chicxulub Crater on the Yucatan Peninsula of Mexico. 1991. Hildebrand and Boynton declared the Chicxulub Crater to be the result of the impact that triggered the mass extinction at the end of the Cretaceous. [50] Hildebrand and others estimated the diameter of the Chicxulub Crater at 170 kilometers. [39]

In 2016, a scientific drilling project drilled deep into the peak ring of the Chicxulub impact crater to obtain rock core samples from the impact itself. This crater is one of the best known impact craters and was the impact responsible for the extinction of the non-avian dinosaurs.
In 1978 the Chicxulub Crater in the Yucatan Peninsula of Mexico was discovered by Glen Penfield, but its significance was not recognized at the time. In 1990, as part of his doctoral program, Hildebrand, working with the father-and-son team of Luis and Walter Alvarez , published controversial articles suggesting that a large impact from an ...
