The Last Days of the Dinosaurs is a 2022 popular paleontology book by science writer Riley Black. [1] Beginning just before the Cretaceous–Paleogene extinction event, Black's book focuses on the aftermath of the asteroid impact and the way that life came back in the million years following the death of the dinosaurs.
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]
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.
Fine dust thrown up into Earth’s atmosphere after an asteroid strike 66 million years ago blocked the sun to an extent that plants were unable to photosynthesize, a new study has found.
Years before the final day of the dinosaurs, gravitational interactions with Jupiter dislodge the asteroid which will become the Chicxulub impactor from its orbit, sending it on a course for Earth. On a spring morning, 66 million years ago, Tanis was a sandbank on the edge of a river near the Western Interior Seaway.
The amount of dust strangling the atmosphere is thought to have been about 2,000 gigatonnes; more than 11 times the weight of Mount Everest. Researchers ran simulations on sediment found at a ...
The researchers said that of all the cosmic bodies they have studied that struck Earth in the last 500 million years, only the one that exterminated the dinosaurs was a water-rich asteroid.
The last chapter deals with the end of the dinosaurs, with a detailed description of the first few days after the asteroid impact that scientists now believe caused their extinction and the longer-term climate effects. He also discusses why the dinosaurs died out while other animals did not, the history of our understanding of the causes of ...
