What If An Asteroid Didn't Kill The Dinosaurs? (4K Documentary) | Dinosaurs Inside & Out

Dinosaurs ruled the Earth for 150 million years until an asteroid impact 65 million years ago caused mass extinction by blocking sunlight and leading to widespread starvation. However, scientists believe the asteroid impact is only part of the story. They're exploring other potential factors, such as the type of terrain it struck and evidence in ocean floor sediments. Researchers analyze sediment cores and plant fossils to understand the environmental changes before and after the impact. Some paleontologists suggest a gradual decline in oxygen levels and other environmental shifts played a significant role in the dinosaurs' extinction.

I’m old, but this video is older…lol…that computer monitor and the scientist’s shirt were my first clues.

[epicduckdoctor]

Could somebody carbon date this video please.

[judgementhallcollections]

Forgive me I was interrupted and wont see the rest of the video til later, but Im stunned over the lack of tseunami from an impact discussion so far....and the amount of water vapor suddenly saturating the atmosphere and the insane weather that might develop on a semiglobal scale quite quickly.

The asteroid didn’t kill the dinosaurs - it was the catastrophic long lasting aftermath!

[HowardCaplan-bl]

It was already known that sulfur played a big role in the Dinosaur Extinction!

Filmed before DePalma's discovery of the Tanis site. That site just nailed it.

This covered nothing about, What If An Asteroid Didn't Kill The Dinosaurs. All about what did happen.

[Mark-flkx]

The title of the video should be changed. This video has nothing to do about “what if the dinosaurs had not gone extinct”.

[jrgnc]

This has nothing to do with "what if an asteroid didn't kill the dinosaurs" It's all about how and why they were killed.

[carlobelen]

Meteor impact triggered the volcano to erupt. Some dinosaurs died from the impact, but most of them died of hunger.

I expected a "What If" Story, not a meager documentation of alternative causes.

[JamesPCastor]

The hypothetical scenario in which an asteroid did not cause the extinction of the dinosaurs presents a fascinating alternative history of Earth. The continued dominance of dinosaurs would have profoundly impacted the evolution of life,

[MehrdadMohagheghi]

Interesting but you didn’t explore the question you posed.

[fredwerza]

Been hearing about the Deccan Traps in India for a long time --- wonder why nobody has done a documentary about it?

[danielhughes]

Where I live, v100s, thousands of fossils are right on top, no digging required, treasure trove, I believe there was a explosion, massive explosion, I have petrified brains, bone fragments everywhere, petrified sides of dinosaurs beef, t/ rex poop v, rapter poop that looks like it was laid yesterday, blood still visible, glass! It's a fossils finders fantasy, I live in calif by the way!😊

A massive impact on earth of that magnitude would have caused tsunamis, hurricanes, volcano eruptions, tornadoes and other weather anomalies for many decades after. Would have changed the atmosphere too. I think it took years to wipe them out

Imagine yourself in a room of fellow high school students, watching this and laughing at the cheesy music. 😆

[MonikaFreemanPilecka]

Thank you for keeping me entertained 👌🙏✌️👽

The meteor was one of the reasons. Because if it had been the only reason then a lot of animals and plants or everything had vanished in a short time. But there was also an eruption of volcanos in the dekkan mountains in india. Scientists believe it lasted 10.000 to 50.000 years. This has changed the environment slowly but steadily And this is the best explanation.

this video is older than the meteorite that killed the dinosaurs !!
