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]
Uniquely, Tanis appears to record in detail, extensive evidence of the direct effects of the giant Chicxulub asteroid impact which struck the Gulf of Mexico 66.043 million years ago, and wiped out all non-avian dinosaurs and many other species (the so-called "K–Pg" or "K–T" extinction).
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 aftermath of this immense asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth. [217] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures ...
The study shows that the asteroid, while having a severe initial impact, did not immediately kill off the dinosaurs - instead slowly killing them off over a few years.
Fischer-Gödde and his colleagues found that, unlike many other impactors over the last 541 million years, the Chicxulub impactor that killed the dinosaurs and up to 75% of all life on Earth ...

[13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...
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.
