Last Day of the Dinosaurs is a 2010 Discovery Channel television documentary about the K-T extinction, which resulted in the extinction of the non-avian dinosaurs. [1] It portrays the Alvarez hypothesis as the cause of extinction. The documentary was released on August 28, 2010 and narrated by Bill Mondy. [2]
Alternatively, interpretation based on the fossil-bearing rocks along the Red Deer River in Alberta, Canada, supports the gradual extinction of non-avian dinosaurs; during the last 10 million years of the Cretaceous layers there, the number of dinosaur species seems to have decreased from about 45 to approximately 12. Other scientists have made ...

A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
Dinosaurs had long ruled the land but, aside from their bird lineage, were wiped out following the impact, as were the flying reptiles called pterosaurs, the large marine reptiles and other sea ...
The first known dinosaur fossil linked to the very day of the Chicxulub impact studied by paleontologists at the Tanis site in North Dakota is reported, [158] with the first reports about the site being from 2019. [159] [160] [161] Conceptual model of the impact sequence at the Nadir impact site, based on seismic observations and analog models ...
Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. 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.
On the last day of the Cretaceous, Edmontosaurus, Triceratops, Tyrannosaurus, Alamosaurus, azhdarchid pterosaurs and a plesiosaur go about their daily lives just before an asteroid the size of Mount Everest hits the Earth, causing the Cretaceous-Paleogene extinction event.
