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.
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 ...

Researchers in Europe and the U.S. have discovered that the dino-killing asteroid formed beyond the orbit of Jupiter in an extremely cold region and was rich in water and carbon, according to the ...
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.
Tanis (fossil site) Coordinates: 46.0218°N 103.7910°W. Tanis is a paleontological site in southwestern North Dakota, United States. It is part of the heavily studied Hell Creek Formation, a geological region renowned for many significant fossil discoveries from the Upper Cretaceous and lower Paleocene. Uniquely, Tanis appears to record in ...
