A New Study Sheds Light On What Killed The Dinosaurs!

Dino-Intro

For centuries, humans have been fascinated by the majestic creatures that roamed the Earth millions of years ago - the dinosaurs. But despite our fascination, there's one question that continues to baffle us: how did these incredible beasts go extinct?

The generally accepted theory is that a giant asteroid collided with the earth, causing widespread devastation and ultimately leading to the demise of the dinosaurs. However, as with many scientific theories, this explanation is not without its doubters.

So buckle up, get ready to travel back in time, and prepare to uncover the truth about the extinction of the dinosaurs! Let's go!

Dino-Extinction: The Nuclear Winter
One of the most intriguing parts of the theory that an asteroid caused the extinction of dinosaurs is the idea of a "nuclear winter." The term is used to describe a catastrophic environmental event that would have occurred as a result of the asteroid impact.

Dino-Measurements: the Mean Annual Temperature
When you get a fever, you might want to measure your body temperature from time to time. Thankfully, we invented thermometers and it’s easy to see if we to take some paracetamol pills or if we are fine.

Dino-Volcano Eruption
Another interesting thing scientists found out studying these bacteria’s fossils is that not only they didn’t seem worried about the coming of any kind of nuclear winter:

Dino-Explanation
Talking numbers, when looking at the average temperatures around 66 million years ago, scientists found out they were ranging between 16 and 29 degrees Celsius.

Dino-Outro
The debate over whether an asteroid impact caused a nuclear winter will undoubtedly continue for many years to come.

“Do you have a better theory? Let us know in the comments” Lol ok. Imagine this news story… “A new theory gaining traction across the scientific community was discovered in the YouTube comments section”

Chicxulub (170 km) was one of the impacts causing the extinction. The largest impact occurred at India and it is unrecognizable under the Deccan Traps. This hipothesized crater called Shiva can be indirectly measured with a diameter of about 630 km by means of the eastern half of its secondary ring (2, 000 km) visible at the Indian Ocean. The other half at the African continent today is known as Rift Valley. Put the pieces together and you solve the puzzle. Other impacts as Nadir (20 km) and Wembo-Nyama (40 km) are aligned with Shiva and Chicxulub in paleomaps.

New evidence from an area north of the asteroid impact now in North America, shows because of spawning fish in a fossil bed, that the impact at Chicxulub took place during late spring.

Dino. Very interesting stuff. Thank for the info.

Back in the middle 80's a Dr Baker from one of the universities in Oregon was interviewed in Montana where he was at several different sites digging up dinosaurs and he stated that they find the iridium level left by the asteroid they dig down 6 to 12 in to find late stage dinosaurs they dig down six to eight feet before they start to find early massively large dinosaurs that there were no dinosaur bones ever found even close to the iridium level. So if that iridium level was actually caused by the asteroid which everybody seems to believe It's all over the Earth, it varies in thickness according to location. So this would leave no doubt the dinosaurs were extinct long before the asteroid hit. He said his personal theory was that we had a spell with land bridges connecting continents and different dinosaurs spread disease killing off both types. Much like the Asian and African elephants can make each other sick.

Nuclear winter wouldn't have had to be very long to cause ecosystem collapse.

[scottgilliland]

DINO! Very informative video, as usual.

[mbisson]

I'm just glad these dinosaurs aren't around anymore. I'd prefer to not become a dino dinner.

(1) Zoo and Museum employees from the future went back in time to capture live dinosaurs, and took too many.
(2) Alien spaceships landed to study them, and decided to take them home as pets.
(3) Dinosaurs developed advanced mathematics, and spent so much time on it they neglected to reproduce...

[jensphiliphohmann]

_What do you think about the extinction of the dinosaurs?_
That the expression is a misnomer: It wasn't _the_ (i.e. all) dinosaurs which went extinct but _most_ dinosaurs, namely except of some relatively small theropods with beaks: The neornithes.
Additionally, the extinction event killed off most larger animals many of them were _not_ dinosaurs at all.

[oxcart]

It's a hypothesis, not a scientific theory!

[ff]

Maybe the Volcan in India was caused by the asteroid impact? They are opposite eachother on the globe and both worked hand in hand.

[mm-dwrr]

I've heard the great flood was responsible for the dinosaur's demise. With so many fossils layed down in sediment all over the world. Thoughts?

[jssomewhere]

Didn't they also discover that the Dino asteroid was not alone. The big one was the rock everyone knows but the new idea is that a 3 mile wide rock hit the planet within several weeks/months of the big one. There may also have been several other rocks ranging from the size of cars up to 1 mile then the two big rocks 3 miles and 6, -10 miles. These were most likely a single rock at some point in the past then due to collision or gravitational interaction the big rock became many small rocks. So what may have been an asteroid of 50-60 miles got torn apart and a bunch of pieces hit the planet. Yet instead of lowering the temp, this pounding set off the volcanoes and warmed the planet also set everything on fire and was able to break down the food chain. They have thought for a very long time that a single asteroid was not the entire issue.
Who was the guy that found the first complete T-Rex in Montana. He's been saying it wasn't an asteroid for 30+ years. Yes the asteroids were a part of it but not all of it.

This thought is kind of a good one for humans. If it takes either a much bigger rock to end almost all life or a series of events. That means we have more time to come up with better plans if one is headed our way but it's only 10 or fewer miles across. Sure billions will die and those that live will wish they had been among the billions, but some will remain and I hope a few of them have a better plan for how things will work when we rebuild.

no signs the bacteria was preparing for winter? seriosuly?

[alexstroud]

Is there any evidence to prove a meteorite hit? Also could they not have all got Dino covid or some thing

[johnsamson]

All of the male dinosaurs decided they were female and procreation failed.

[andrewaguirre]

I don't know what to think about anything really
