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.
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 ...
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 ...
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.
[15] [16] The Moon's gravitational pull stabilised Earth's fluctuating axis of rotation, setting up regular climatic conditions favoring abiogenesis. [17] 4404 Ma Evidence of the first liquid water on Earth which were found in the oldest known zircon crystals. [18] 4280–3770 Ma Earliest possible appearance of life on Earth. [19] [20] [21] [22]
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.
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.
