Did an asteroid kill the dinosaurs?

Around 66 million years ago, all non-avian dinosaurs went extinct. Was the culprit a 6-mile wide asteroid that collided with Earth? Or did other factors contribute to the dinosaurs’ die-off? Paleontologist Aki Watanabe looks at other theories for why dinosaur populations declined during this famous mass extinction.

There are new episodes of Space Vs. Dinos out this weekend! Watch here: kzbin.info/www/bejne/injCoWZ5hat9o7s

When the hell did it change from 65 to 66 million years ago? This really upsets all my time travel plans.

[@dbtest117]

Both are most likely very exaggerated.

[@AmericanMuseumofNaturalHistory]

Not sure when it changed exactly, but as isometric dating and stratigraphy techniques improve, scientists continue to refine this timeline!

[@greenmachine949]

@@dbtest117 - Well I need pinpoint accuracy so I can go back and visit some glorious dinos some day. I don't wanna emerge from my time-pod into a raging firestorm of toxicity. I could go on Twitter for that. :-P

[@dbtest117]

There are some claims of C14 dating of dinosaurs soft tissue. Soft tissue was confirmed a few years ago. But few scientists are even willing to even try to verify or prove the claims wrong regarding C-14 results. I would place my bets on that in some years to come there is a big scandal rolling up infront of us. Usually the truth comes out sooner or later. As for the moment the scientific method is not allowed to function or have its course by scientists on this issue. Which is odd as scientists normally should not be afraid of a scientific method for dating like the c-14. If it were allowed it would shater any doubts. But as it is now this is actively being hindered from happening. The confirmed soft tissue from dinosaur remains is already a very big nail to the coffin of this teory of 65-66M years. Im loking forward to the “scientific” circus arround this issue.

[@greenmachine949]

@@dbtest117 - Interesting. I just looked that up and it seems their claim is the bones examined by carbon-14 dating were under 40,000 years old. A 2012 geo-science conference rejected it and covered it up stating to the group presenting it that there HAD to be an error. It ironically reminds me of that ST Voyager episode where that alien dinosaur race , the Voth whose leadership rejected any scientific evidence of their origins on Earth as being "against doctrine" and covered it up by any means necessary.

After all these extinction events one thing is clear that its very very difficult for an extinction event to eradicate life from a planet completely .

[@kimberlyanne434]

This is an interesting video. Thank you from Tucson Arizona 🌵

[@Zenbeau]

wait this doesn't make sense to me lol. so you're saying one asteroid which estimated size 10 km - that's nothing dude, that's like the size of a small town (no i get it, its big, its huge, but still its the size of a small town right) So you're saying ALL of these dinosaurs were hanging in ONE spot? one asteroid. Dinosaurs lived on every continent, they were everywhere. so how could that be? the ones killed by the asteroid would only have been a small portion of the species LOL and even if they were in the same spot, so why didn't they just move to a different area to search for more plants (food)?

[@punkgrl325]

This is a really adorable video for such a horrifying series of events.

[@cordatusscire344]

Thanks for the video! And as for what happened to them.. I'd say no one event killed them. It was a combination of several different systems of events that led to their overall downfall. It seems rather obvious (non-expert) to me that if an impact from space is what killed the dinos, then it would have also wiped out the smaller creatures that depended on vegetation for survival. Makes more sense to me if several smaller scale events with large effects over the course of a few tens of thousands of years just led to the gradual decline of the very large animals and gave those that could make the change time to adapt to a new low-food environment. Which basically means everything had to get smaller and eat less to survive. Those are my thoughts on it anyways.

[@SpeakTheTruthLouder]

Literally everything you said and what the videos said are both just would haves and could haves with no actual evidence or data. This is not science. This is just guessing. I hope you stop thinking this kind of BS should be acceptable as science and the way you guys are willing to spread opinions of certain people as science. This kind of mental laziness and guesses need to stop. This is not academia or true scholarship. Why is the younger generations making science just useless talking? Have we become so dumb as a world that no one even thinks they NEED to put in actual work, test and prove things - or else it ISN'T true? This is why this world is becoming so bad. Your science is as good as what crooks in uneducated times. I can't. Sorry - this whole theory is the dumbest guess a child can make up, and it's NOT OKAY to keep pushing them on the internet. You're destroying our already dumbed down society. People need to learn integrity and stop being crooks.

[@Kid2002]

I really like these theories, I always loved dinosaurs my whole life

[@kiyolinkameronperumal6483]

This is a really nice video. At the end of the it I had the thought that the main factor in the extinction of the current animal species on earth, is human behavior. Even though there hasn't been any trace of another dominant species during the cretaceous period yet, can we be absolutely certain that there wasn't such a species? Maybe to further understand the previous events we could analyse whats happening now too... Just some random thoughts

[@SpeakTheTruthLouder]

No it;s not a nice video. This whole thing has ZERO science in it but just a bunch of guessing and speculations. This is as accurate as any fiction and many fictional story could pass as more likely science than this guessing. There is literally nothing to prove this at all. but just a few people who made some personal guesses and this theory got passed around cus most of you are mentally lazy and don't realize science requires integrity, testing of ideas and solid results to prove or reject them. You demonstrate no critical thinking at all.

Why do video creators constantly point to the top left or right corners of their screens and claimed that they will be a link provided "here". Yet every single time I hear that, and it's quite frequent, there is never ever a link provided. What gives? Does KZbin delete them or do they forget to put it in, what's going on with that?

[@iviewthetube]

Wouldn't the impact itself cause increased volcanic activity from the disturbances?

Some scientists are exploring this, but nothing conclusive has tied the two together yet!

[@IrishCoven]

I would think so. Maybe even earthquakes too

[@Gravvvyyy]

If they cause tsunamis and other natural events. I'd say its logical that the tectonic plates could have been shifted slightly as well to cause some upending.

[@tomvelardi3754]

The Bible mentions Dinosaurs in Isaiah 30:6 and Job 40. There are animals living today land and sea that lived with dinosaurs. The Bible also mentions a flood in Genesis 6 that would have lead to mass extinction. I don’t think the asteroids destroyed everything though they did kill a lot.
