Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines) The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo ...
The Cretaceous–Paleogene (K–Pg) extinction event, [a] also known as the Cretaceous–Tertiary (K–T) extinction, [b] was the mass extinction of three-quarters of the plant and animal species on Earth [2][3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.
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]
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
August 16, 2024 at 11:24 AM. German scientists think they've cracked the case on the origins of the giant asteroid that all but wiped out the dinosaurs 66 million years ago. The huge space rock ...
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago. Dinosaur-killing asteroid was ...
Alvarez hypothesis. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth. Prior to 2013, it was commonly cited as having happened about 65 million years ago, but Renne and ...
Scientists may have finally found where the object that wiped out the dinosaurs came from. The mass extinction event that occurred 66 million years ago – the most recent on Earth – came about ...
