<P> Coordinates: 21 ° 24 ′ 0" N 89 ° 31 ′ 0" W ﻿ / ﻿ 21.40000 ° N 89.51667 ° W ﻿ / 21.40000; - 89.51667 </P> <P> The Chicxulub crater (/ ˈtʃiːkʃʊluːb /; Mayan: (tʃʼikʃuluɓ)) is an impact crater buried underneath the Yucatán Peninsula in Mexico . Its center is located near the town of Chicxulub, after which the crater is named . It was formed by a large asteroid or comet about 10 to 15 kilometres (6 to 9 miles) in diameter, the Chicxulub impactor, striking the Earth . The date of the impact coincides precisely with the Cretaceous--Paleogene boundary (K--Pg boundary), slightly less than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from the event was the cause of the Cretaceous--Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth suddenly became extinct, including all non-avian dinosaurs . The crater is more than 180 kilometers (110 miles) in diameter and 20 km (12 mi) in depth, well into the continental crust of the region of about 10--30 km depth . It makes the feature the third of the largest confirmed impact structures on Earth . </P> <P> The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán during the late 1970s . Penfield was initially unable to obtain evidence that the geological feature was a crater and gave up his search . Later, through contact with Alan Hildebrand in 1990, Penfield obtained samples that suggested it was an impact feature . Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas . </P>
