These types of shows are what we need on TV, honestly.
When I was growing up there was National Geographic specials, and Jacques Cousteau. I loved watching them.
No we dont cuz its a lie.
Bible thumpers will not like it
Agreed! I used to watch TLC when it had shows like this. Then it switched to reality shows and became a terrible channel.

We’re basically living in a post apocalyptic world
When Adam and Eve lived in a paradise Earth and then rebelled against God, this is how God cursed the earth as he had told them he would.. the asteroid hit so hard that it shifted the earth's axis by 23 degrees. If these scientists could figure what angle it came in from, based on the degree of impact, they would know the exact position of the earth when it hit.. That would be interesting and would also confirm the fact that it did cause the earth to shift on it's axis.. It would have had to come in from the South Pole and struck North of the equator..or it would have had to come from the North and struck South of the equator. When the earth shifted, it resulted in the tectonic plates breaking up and pressure from the earth's core releasing massive amounts of pressure that pushed the sea beds up, creating the tsunamis, volcanoes and mountains. At zero degrees tilt, the earth would be a paradise, with it's foundation all intact and very mild seasons, along with perfect tropical like weather... plush foliage throughout the entire earth. Palm trees and other tropical vegetation have been discovered under the ice at the North Pole.. Mastodons found frozen with vegetation still in their mouths under the ice at the North Pole..Proof of a once perfect earth that flourished over the entire planet.. And B T W , there were never any flesh eating dinosaurs.. Scientists base their flesh eating theories on the size and structure of their teeth.. They've found no evidence that dictates any kind of dinosaur dieted on flesh. Those dinosaur that survived the asteroid could have possibly fought others over the scarce vegetation that survived, thus presuming they were flesh eaters... but prior to that, they and all other animals survived on vegetation. Scientists are always looking for something new, which is great, but some do it in order to get recognition for themselves and then convince others to adopt their suggested findings. Just like carbon dating.. determining the amount of carbon 14 in the remains of deceased animals and the rate of decay... It isn't overwhelmingly accepted by all scientists as fool proof.....therefore, their dating of events consistent with fossils and bones of the same era aren't fully accepted as accurate..
classickruzer1 Amen you are correct
classickruzer1 sorry dude I’m not religious
@@classickruzer1 "They've found no evidence that dictates any kind of dinosaur dieted on flesh." And the meat eaters of today have teeth that are just the shape of the teeth of the vegie eaters. OK! Tell that to a T Rex.
@@classickruzer1 Haha, very funny. If you believe all that, you're an uneducated fool. I'm not going to even try and point out the many fallacies in your little speech, except for one. Carbon dating is not used by paleontologists or geologists for anything over 65,000 years old. They use radio-metric dating. It measures the half-life of elements, not carbon.
This is legitimately so interesting, props to my science teacher for making us watch this
One of the best documentary i have ever watched. It explains in great detail how the whole extinction event of dinosaur unfolded.
Wow hats off to this photographer, he really put himself in danger taking all these shots
True, if one of those tyrannosaurs had spotted him...
Goodness....hahaha

Btw, cameramen are demigods and can’t die
I am kind of crying right now because these selfless scientists/researchers spent almost all of their life in pursuing knowledge and knowing the unknown, contributing to society's knowledge. Through these people we were able to develop. I am really thinking that I am just an insignificant being by only thinking my own well-being.
John Olpenda: Happy Birthday. Are you 27 by chance?
@@SovereignStatesman no, I am just really sincere.
Elon Musk says: Make something that will add to someone's life, even if it's just a video game. After you've done that, then you will be in a position to do something better, and then something better, and so on. But you must put work into it
@@johnolpenda9803 Please keep in mind that most scientists like these palaeontologists are very passionate about their work, are very interested in the subject, are very curious and are probably the type of people that get a lot of joy simply from solving and completing difficult puzzles of any kind, so their motivations are not completely selfless.
Of course their primary aim is to contribute to human knowledge, but they wouldn't be able to to study and work hard at it for years without enjoying it in the first place.
People produce the best results if they love the work they do, so gaining a career that matches your natural interests is an excellent achievement in itself.
So if you wish to contribute to the world, the best place to start might be to work out what you are most interested in or what activities gives you the most joy and capitalise on it somehow.
And if your main love is simply in helping others and you aren't scientifically inclined, there are certainly many options for that, ranging from healthcare to teaching or from charity work to conservation projects.
But the main thing to aim for is to love what you are doing, because every day you do it will be a pleasure, which means that putting in lots of hard work and time will never be a problem for you.
true
Damn, when you think about how terrified these poor creatures were...Everything they knew was coming to an end. If something similar happens to us, few; if any, will survive.
Being "terrified" is more of a complex human emotion, they were probably just confused/shocked and felt "pain".
I don't believe that animals brains process feelings and emotions on a complex level like we do (if they did we'd be in trouble lol).
I like to think the "thought process" of the dinos at that time were " wtf is that?" To "damn" lol
@@astroninja853 ffff FIGURE
@@astroninja853 they wouldn't be terrified per se about what was going to happen, but the sensory overload, and later the extreme pain right before death would probably give a panic response
partial dissolutions happen to help rid the Earth of evil and to give us a cleansed new start, helping the Earth replenish - God is not done with the Earth, partials happen periodically..........this was one time but apparently it happens every 3600 years or so, we are overdue.......Revelations 8:11 KJV....
Man its really crazy to think about how many things that we now know as "common knowledge" used to be entirely unknown, and cutting edge discoveries. I think I've been taking that for granted.
Yes and let's hope there are many more to come.
Just wait 1000yrs and if our planet is still here, see how much it's changed. If you're still in human form more power to your incarnations!
@Roy G Biv By aging rulers trying to hang onto their power?
This is still a theory
Exactly.
A guess. But I know the earth is flat.
I don't know what I'd do without the bearded guy explaining everything.
That beard guy genius and smart
Im guessing go eat a bunch of snickers bars?
Only just started this and I’m excited for the bearded man to appear.
You'd manage, LoL
Always trust a beard when it comes to science
I had the distinct pleasure of briefly working with Luis Alvarez in the late 70s. What a treasure he was.
I'll tell again I've watched many videos about this subject and this is the best by a big margin
"He is a time traveller"
***drives slowly in his car***
Dinosaurs: Vibing
Some rock: Ima boutta end this mans whole career
You're a riot
well technically you could say that the asteroid hitting the earth was more like a "Imma begin man's whole career"
@Isaiah Bakombo 20% of human genes are foreign (not of this earth) so praise the rock! It carried microrganisms
Isaiah Bakombo if the dino’s did not go extinct humans would have probably been hunted to excintion
@Isaiah Bakombo Maybe better watch that part again. The rock killed the dinos; the dinos prevented mammals from flourishing. Thus once the dinos were gone, other primates and finally humans could develop
I've often wondered how exactly the remaining animals survived, both during and just after the event. It must have been an extremely hazardous and difficult time.
I'm more concerned about how the creatures survived after the Permian extinction. The Cretaceous extinction is understandable, small animals simply fed on the carcasses of dead dinosaurs. And during Perm there was a real hell
Soon you will fell it in your own skin! Because history happens in loops!

Yes, you said it perfectly
Where , did the asteroid hit? Anyone know? Did this happen? Or is it just a theory?

OMFG, the idiotic comments here are seriously scary. People actually believing this is all fake? How absolutely bizarre. It looks like only a small portion of humanity are able to use the brains that evolved. Thank you for an excellent presentation, biointeractive.
Don´t worry. They are a minority in the real world, but they are a majority in the fantasy world of commentators.
Meg: well it IS computer-animated, not live-action footage of the actual impact.
We should split up and look for clues.. no in all seriousness i agree people do get way too personal in the safety of the internet. There are many egos in the world, it is natural but many of us have to watch perplexed as some let theirs ruin their time more than others. Thats why its a silver lining that there are still good people, people who give hard workers credit like you did in your comment. They are the comments these guys read smiling. For jerks with too personal comments I always have a laugh lending a hand to wind them up so i cant say anything really lol. A point people dont point out though good on you. Peace
Oh and to the McDeath fan and the cumbersome composer... GROW THE HELL UP FOOLS!! 🤣🤣🤣🤣
Not in the Bible = not true
I love how they put together all of the clues from around the world to understand how, when and why the dinosaurs went extinct. It's amazing, thank God for smart people!!
What's a God?
"What the asteroid impact taught us about evolution is that it's not always about survival of the fittest. Sometimes it's about survival of the luckiest." Sean Carroll hit the nail on the head with this statement. Luck is a key factor in survival, not only as it applies to whole classes of animals, but to individual organisms (including humans).
...but he doesn't seem to understand what "fittest" means. It in no way precludes luck.
Every time I watch a simulation of dinasour extinction, I feel sad about those poor creatures
I feel happy that this gaints are no more that's why mamals evolved and we have a terrorfree life.
It's incredible to think that all of our ancestors were there, and experienced the horror too.
Who's to say it won't happen to us!
If dinosaurs were alive presently, I don't think you would say that.
Yes, who knows if they were even sentient. Reptiles, but who knows.
when you think you're having a bad day, think of this.
This program is a lie it was a solar flare and pole shift that killed the Dinosaurs look at the sun it’s about to happen again
@@paulacannon3452
I believe this program.
great comment .....made my day... feel better now
@@paulacannon3452 Or comet enke leftovers in the taurid stream? A crator found in nov 2018 in greenland is causing a stir. More being discover by LIDAR technology. Where are you getting the solar flare hypothesis? Robert Schoch? Sounds interesting!
When you think you are having a bad day, remember.... Jesus, betrayed by his one of his own, all others deserted him, the only sinless human died a very bloody, cutthroat, brutal criminal's death. Flogged, beaten, forced to wear a crown of thorns making him bleed more while carrying a very heavy wooden cross, up hill... Then nailed it and ultimately crucified. Crucifixion was very painful. And when you didn't suffocate in a timely manner, both your legs were broken to facilitate suffocation. (However his legs weren't broken).
That is still a VERY bad day to be betrayed, abandoned, beaten, mocked and nailed down dying a criminal's death when you didn't do anything wrong. That is the worst day.
Wow, these type of documentaries that answer so many questions I had about the extinction of dinosaurs are very rare!!
A brillant production! Thank you.
Glad you enjoyed it!
“Without the asteroid, there’d be no us.” Great job! Thanks a lot.
I disagree, the asteroid might have set evolution BACK by tens of millions of years.
Now we have people looting because they feel entitled to because they feel oppressed people becoming offended for no apparent reasons killing one another to push agendas. Yes evolution At its peak. I mean at least the dinosaurs killed for a reason food.
We could easily be next and it may not be an asteroid next time. When I look at the night sky just to I check if Betelgeuse will go supernova. I am told that supernovae can fire off major gamma radiation from their poles... talk about being fried!
Justin Laski did u see it unfold ? Lmao nobody will ever know it if was volcano or asteroid or could of been both. We only go by assumption and theory
“So all this mountain was once at the bottom of the ocean”? “Exactly” This man also knows that the sun goes up and down and up and around
I grew up on a farm near the pretty rock hills. Dad once found a huge bone while plowing his field, he brought it home and we kids played with it for years. Dad thought it was a big bison leg bone, but it was petrified. Now I believe it was a dinosaur bone. Wish I had hung onto it, but it probably still lays somewhere on our old farm-site, when we moved from in int 1959 nobody ever moved in to live there, it is now part of a pasture belonging to the neighbor that dad sold out to in 1963.
Gotta give it to the animators too, it looks so real. Good job 👍🏻

big plot twist: dinosaurs had nuclear technology and wiped themselves out.

When does that Cow, (on the moon), show up in the history time line ?
Asteroid??? No sorry what killed the dinos was the great flood. The proof is the recent findings of soft tissue inside horns e bones, only possible in animals that have died a few thousands of years and not millions. Sorry evolution man.
@@daniloarq bro... you are actually slow
Fascinating and such an important subject
I am amazed at how beautiful this documentary is …
"It's not always about the fittest but also luckiest" Nice!
It is a fallacy of reasoning. If luck was involved then there still would be dinosaurs. Only the fittest survive.
The Mammal were fitter than the Dinos for the conditions that existed after the asteroid crash. So it is still "the Surviving of the Fittest."
One of the best documentary i have ever watched. It explains in great detail how the whole extinction event of dinosaur unfolded. My respect increases manifold for the scientific community for doing all these research and hard work to excavate the truth.
This video also makes us realise how insignificant we are in this vast universe. One asteroid or one virus outbreak could wipe us out of this planet just like the dinosaurs.
Wow, thank you!
Yes, and to think they were here for hundreds of millions of years - all gone. I read once that the amount of people responsible for keeping an eye on the asteroids that might pose a threat to the earth is about the same that would staff your average McDonalds. That’s pretty scary.
Dinosaurs are fake. How could they be on earth billions of years ago, when the bible says the only thousands of years old 🤦🏿♂️
@@triopharaoh I’d like to point out the obvious flaw in thinking the earth is only a thousand years old. at that time seeing as there was no humans before then to record anything, that would presumably be the age they assume because they’ve been here observing for a ONLY a thousand years.
@@biointeractive Repent and believe the gospel
this is a great documentary clearly explained. been watching docus about dinosaurs and found this video.
This is one of the best explanations of the mass extinction of the dinosaurs that I've ever seen. I loved the history portion of the video. My dad showed me the KT boundary when I was a kid and I thought it was pretty cool. It really must have sucked to be alive on that fateful day.
REMEMBER - Another asteroid is on its way. It's not a matter of IF, it's a matter of WHEN.
Not one 6 miles long
Yeah, best bet is being right where it hits. Go out quickly, not even knowing what happened.
it's absolutely insane to think that something like this could possibly happen again - because now we know something as catastrophic as this is totally possible. the future of the dinosaurs if the asteroid had bypassed the earth is also something to think about.
It would be interesting to see if human's more advanced intellect would allow us to save some of our species or not.
I believe that to be a matter of time. But, no worries. We wont live to see it. Mankind will be responsible for its own extinction way before that happens again.
we could be history at any time, humanity is still very young.
That never happened, but something much bigger than that myth is going to happen...It's called WW3...Nuclear WW3...You can bet your house on it, it's not if, but when!
@@stevefowler2112 Most likely, a bunch of people would deny there was a problem or try to pray away the asteroid, like with climate change.

This video encapsulates everything that is positive in RUclips. I am well versed in the KT boundary event but have never seen it analyzed in such detail. Great video! Hope you folks with kiddos watch this with them and potentially inspire some new scientists, archaeologist, or any other discipline that might apply.
I am curious what you would say and what the channel would say about all the overwhelming evidence showing that dinosaurs and man did exist together.
For starters, fresh red blood cells found in dinosaur bone, which would not happen if they existed millions of years ago. And even more ironic discovered by someone who is not a Christian.
@@davidross5593 Give me link to that data. I do have heard about the "bloody bones", and like to read up on it. And I am christian, however the Bibles words should not be thought out like a "gospel". As any historic document it has the tendency to be a blunt object from the past, written by the winners/survivors from the time.
Are you of the ideas that women shall not speak in church (or in any open forum). That the 10 holy worlds has not been changed over time?
I look on the Bible as one part history of people and one part a message of love and peace (yes it sounds flower and power). Most of all a message from a higher power that is both a harsh and benevolent being.
So there it is, show me a link that can lead my closed mind.
I
George Ross humans and dinosaurs didn’t coexist and it is scientifically proven with LOGIC. Not some bible or mythology created by humans some 1,000 years ago about some man who created the earth and everything in it. Wake up
@@davidross5593 There is NO overwhelming evidence that shows dinosaurs and man existing together; in fact just the opposite. Science has accounted for those soft tissues being preserved for over 65-million years. Get a grip on reality.
This is easily the best documentary that I've seen on the subject. Lays out concisely how science works.
And then you look into the comments section and read the posts of religious fundamentalists raging about how science lies to us and how the only truth is delivered by the book about the invisible man in the sky, written by ancient goat herders who didn't know the Earth orbits the Sun. And you ask yourself: Am I really living in the 21st century?
You will always get comments from people who doubt anything that goes against religious teachings. The Arc that was built in Kentucky several years ago has one display where a human is riding a dinosaur that's about 7 feet tall as if to say that dinosaurs and humans existed at the same time. People really believe that stuff and would rather believe the stories in the bible written by men that were very naive about everything except farming and whatever it took for them to exist.
The fact that a 6 mile rock would find a planet and alter its course shows Devine intervention

very educative. Thank you very much for all this work
Glad it was helpful!
Very insightful, Great video 👍👍
this is one of the best films about the subject anywhere, apart from national geographic and the smithsonian, film vaults. nice photography.
how could people not believe a comet impact, it makes so much sense, a volcano, earthquake or tsunami could not hope to deposit immense amounts of iridium
There are almost always other explanations for all the effects discovered. The one whose entire story, leaving the fewest holes and the fewest unexplained facts, is probably the right one. In science it is always necessary to make your case; it is not required that anyone believe you; belief is not important. Facts are.
Agreed. Iridium isn't abundant on earth, it comes from space.
A large meteor of the size proposed, landing in the site proposed, would necessarily cause a devastating tsunami and an earthquake of some magnitude. Even a relatively small asteroid hitting the Earth today would be detected by seismographs locally, and something measuring less than a hundred metres could be detected globally. These objects have massive amounts of kinetic energy. It is not beyond the bounds of possibility that large scale volcanic activity could be (and there is some body of evidence to say 'was') caused by this particular meteor strike.
@@janbadinski7126 Most of Earth's Iridium is beneath it's crust.
@@puncheex2 Correct. There is never just one piece of evidence that confirms a theory. It is a series of confirmed evidences, like putting many pieces of a jigsaw together until you go from "I think it LOOKS like a boat." to "It IS a boat."
(However, there is sometimes a "mike drop" piece of evidence that confirms something so fundamentally crucial to theory that it could kill the theory if it isn't found. The gravitational bending of light confirming Einstein's General Theory of Relativity, for example.)
A lot of crackpots who deny science hinge their denial on "Show me this ONE thing that proves your science is true." But a scientific theory just isn't based on "just one proof".

Normal people: cool rock!

Fun Fact: If some alien race 65 million light-years away were to take a picture of the Earth they would see the dinosaurs on Earth.
@Tcbranger dang it
Well, if you could build a craft that could fly faster than light, then you could go to a planet X+65 million light years away X being the time for the craft to get there, you could take a pic yourself.
Lets hope they do not have reptile phobia and launch their mega laser
It's an insanely difficult task. Our picture of M87*, the black hole, which is 53.5 million light-years away, took a telescope basically the size of the earth, yet we only see a fuzzy outline of the black hole even though that shadow is about 312 AU across. Earth is 0.0000000852 AU in diameter, which makes imaging it many orders of magnitude more difficult from that distance, let alone individual dinosaurs on its surface.
@@astr0nox yeah it impossible with our understanding.but for really advance civilization maybe not, but for me i doubt that.this distance is to far

discoveries are. No wonder my old Life books have it wrong. Again, great job! Thanks.

Amazing footage, respects to the camera crew that risked their lives to bring us this.
Excellent lesson on the KT boundary.
This lays out all the evidence in such a precise way. It's really interesting
no evidence whatsoever and we will never know what happend
If a meteorite actually took out the dinosaurs than the K-T boundary would be packed with bones. They find close to the boundary, but they don't find in or right behind the layer. The dinosaurs were already dying off before the meterite hit.
That was my immediate thought ! the layer on top of the K-T would be thick with bones ?
@@timsmith8797 The meteorite was only the beginning of the end. As you said, they were in the path of extintion before the impact, and that precipitated the event. But not inmediately. They died presumably hundreds (thousands) of years after that.
An extintion event may not be an event that kills every individual of the spicie, but an event which attacks it in a way that makes it die over time
@@mp3ste1 read about the great flood, in Genesis. Then you can research how the dinosaur fossils were all found in great heaps together, in the layers left by the waters, with their necks thrown back.
On the research vessel I served on for 15 years, we cored the KT boundary many times. Along with my many duties aboard this ship was to align and maintain the microscope on board for scientific use. We typically sailed 8 micro paleontologist who studied and classified the very thing spoke of in this wonderful piece. Our best core of the KT boundary was taken from the New Jersey coastline.

I learned more here about what happened to the dinosaurs then I did when I was in school.
Than I did when I was in school not then.
Didn't spend too much time in school, did you?

I love documentary s . Like this. Would love to go on adventùres like these guys
its not adventures its hot painstakingly slow work,,,
Go to school and become Indiana Jones!! This is a pain in the ass slow process!!! Hella rewarding tho when u find a dope ass fossil!!
In South Africa's Western Province there is ample evidence of sedimentary sandstone which was deposited in layers and eons later pushed up into mountains , The area is the Swartberg .
Excellent documentary work, lucid explanations, thanks to all involved. Really enjoyed that.
Many thanks!
“ The greatest scientific detective work ever known”...over what must be a frustratingly long time for all of them. Each new find adds one more piece to the puzzle.
They are wrong, think ,planned,,

Mark Bunds Yep just imagine starting a jigsaw at age 30 and then spending every spare moment on it for 40 years. Then it takes another 60 years for it to be finished. That takes a patient person.
"All right, Mr. Mud Deposit. WE ask the questions here! Where were you on the night of February 12th, 65.997.982 B.C.? Don't try to deny a thing. We've got silent witnesses!"
When I look at this I realised how short our time here on earth actually is..
The entire history of humanity is not even a blip on the timescale of the universe, let a lone a single person's lifetime. If we go extinct, the universe will go on just fine as if nothing even happened. Pretty mind boggling stuff.
Totally awesome video!
Thanks so much!
Wonderful documentary.
Many thanks!
I still remember the day like it was yesterday when my 8 th grade teacher said with confidence that the dinosaurs died because there brains where too small.
silo3849 Naah. Nancy Pelosi is doing just fine.
I remember the day (in 1979) when my college professor told us about the world-wide layer of irridium being found, and its implication that an asteroid impact wiped out the dinos (quickly).
It was so shocking and exciting. I also remember how slowly it took for it to be accept over the prevailing theory of volcanos being a major driving force in their (much slower) extinction. Many did not give up the volcano hypothesis very easily.
But it was quite exciting as a student.
i keep seeing the number 8. yours like the 8th time
play 316 on the 8th. tomorrow lottory
silo3849 if that’s was the case pretty sure that teacher would be extinct too
So what this means folks is that we all could become extinct this way too. What has happened geologically or astrologically in the past will surely repeat itself.
I’ve watched this twice! I find it absolutely fascinating- well done!
Wow, thank you!
Watched 3 times showed my in laws,thank you...
Loved it great presentation...
Glad you liked it!
Best documentary on KT boundary I've ever watched, very easy to follow and informative.
ditto
I'm ganna go find me a ktb/kattie boundery line.
I find it hard to believe that most people tend to believe whatever info proclaimed in such documentaries. These supposedly info are based on uncertain theories based on other uncertain theories based on different uncertain theories. Nothing with solid proof. All prepared by atheist scientists on purpose to attack our Holly Bible. They keep on coming with new different theories every 5 - 10 years or more. Every time they claim to have found the true story. Even their time-dating methods are deficient by few millions of years (depending on the items/periods) as they know it but don't admit it except when cornered. Strange that most people tend to believe what they see on TV and on Hollywood of self-claimed true stories. Listen to what they say and the style of their answers where you may detect their own doubtful ideas (or lies) that they promote purposely to fight Christianity/Judaism. They force us and our children to believe in such garbage with no proof except lots of bones and their rich imagination.
@@ibatan2981 at least these theories have evidence or proof unlike what any bible thumper could pull out of their ass
@@ibatan2981 the great thing about science is that it is constantly improving on itself. Of course there are scientists who get stubborn about certain theories but overall scientists want to search for the truth. When a new, improved theory pops up most scientists adapt and accept it. We don't know until we do.
I don't understand why you can't believe in God and also in theories like the ones presented in the video. Consider science the exploration of creation if you want. In this way, science is an act of love to know God's creation. Science and religion are not in opposition to each other necessarily.
"What would make these little creatures disappear?"
Scientist: "yes."
Y e s
But the plot twists..
There's a virus that Kill them
Very good presentation, no frill, straight to the impacting point - pun intended :-)
It was the little creatures that survived.
I'm here in 2024 and this is the kind of history I love to watch, true reality shows
and informative.................thank you so much!
What if it’s actually that they became smaller and now we’re the giants
Said by every good detective, "we're getting warm!" Love this!
