Timeline of Cretaceous–Paleogene extinction event research Hildebrand and William Boynton reported the Chicxulub crater in the Yucatan peninsula of Mexico as a probable impact site. While the controversy continued, the accumulating evidence gradually began to sway the scientific community toward the Alvarez hypothesis. In 2010, an international panel of researchers concluded that impact best explained the extinction event and that Chicxulub was indeed the resulting crater. Because the estimated date of the object's impact and the Cretaceous–Paleogene boundary (K–Pg boundary) coincide, there is now a scientific consensus that this impact was the Cretaceous–Paleogene extinction event which caused the death of most of the planet's non-avian dinosaurs
Chicxulub, Yucatán (or "puerto") of Chicxulub, 6 km east of the nearest town, Progreso, lies almost exactly on the geographic center of the crater. The name Chicxulub is Yucatec Maya language, where "ch’ik" means "flea" or "tick", and "xulub’" means "devil, demon, or horns". Chicxulub, Yucatán Chicxulub ( "Ch’ik Xulub") is a town, and surrounding municipality of the same name, in the Mexican state of Yucatán. At the census of 2005, the town had a population of 5,052 people. Chicxulub is most famous for being near the geographic center of the Chicxulub crater, an impact crater discovered by geologists on the Yucatán
