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]
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.
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 ...

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 ...
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.
Megatsunamis, burning ejecta from the impact, an overheated atmosphere, and acid rain wipe out a majority of life on Earth, bringing to an end the reign of non-avian dinosaurs and destabilizing the marine food web. Abyssal scavengers and insects survive by feeding on the dead organisms.
In a study published by Chiarenza et al. (2020) [144] [145] the two main hypotheses for the mass extinction (the Deccan Traps and the Chicxulub impact) were evaluated using Earth System and Ecologial modelling, confirming that the asteroid impact was the main driver of this extinction while the volcanism might have boosted the recovery instead.
