[PAR] [TLE] Adriana Ocampo [SEP] Adriana Ocampo is a Colombian planetary geologist and the Science Program Manager at NASA Headquarters.  Her research contributed to the understanding of the Chicxulub impact crater.  She has led six research expeditions to the Chicxulub impact site.  Ocampo and her colleagues also discovered the Aorounga Crater Chain in Chad in 1996. [PAR] [TLE] Chicxulub crater [SEP] The Chicxulub crater ( ; ] ) 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 km in diameter and 20 km 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.
