Ever wonder why the dinosaurs disappeared? HHMI BioInteractive investigates the cause of the mass extinction at the end of the Cretaceous period—and the clues come from paleontology, chemistry, physics, and biology.
This three-act film tells the story of the extraordinary detective work that solved one of the greatest scientific mysteries of all time. Explore the fossil evidence of these prehistoric animals, and other organisms that went extinct, through this lively educational video.

THAT SCIENTIS ARE NO EDUCATION SHAME !!
KT boundary = the ancient version of the George W. Bush era
Toxic plastic "the day Chinese engineering killed the planet" over a penny..
But weed is still illegal in most of the united states even though nuclear fallout is giving deer tumors and killing us like flies..ironic as hell isnt it?
Two UFOS @ 32:00 +/-
They DROWNED during Noah’s Ark
you can find those tiny fossils but not mountain size megalithic giants you people are blind as hell there are giant mud fossils everywhere!!!!!!!!!!!!!! um? how did they lift the giant stones? you cant figure out open your eyes dumb asses!
If dinosaurs died by asteroids, the way they died should showed burning or impact of explosion, but their bones showed differently, it's more likely that the "Great Floods" was the cause of their extinction…
Why they disappear in my humble opinion. They were created by the fallen ones mixing DNA .. and abomination that were never meant to exit.. the Lord of host took them out…
Who sees a cat in the thumbnail?
Ok what causes fossilization something being burnt or something being drowned? And how is it that everything they think they know is absolute? They themselves admit not knowing
G'day YouTubers. Wow you learn something new every day very interesting I'm just gonna to say one thing have they seen or studied the crater at Wolf Creek in Australia. It is enormously Hhuuugggee… also there's a serial killer out there that hasn't been caught yet that's been killing for 30 plus years. These even movies and mini series about our Wolf Creek…
Good Razorback hunting good human hunting.,
Cheers from down under..
Next Asteroid please. We deserve it.
???
there were no dinosaurs. It´s fantasy garbage.
how did life come back after the explosion?
No the book of Enoch has it all, god flooded the earth to get rid of the abominations that the fallen angels had created, no mystery.
We have this layer vissible here in Denmark also. 'Stevns klint' is the place.
Ummm no, worldwide flood happened in one day. They were gone because the dinosaurs and other beings were killed; they’re not a part of God’s creation. They’re a result of amalgamation. It’s happening again.
I hear the words: scientists’ ideas, hypothesis, assumptions is nothing compared the the word of God. The Bible said the earth opened and release the water. The foundations of the earth surfaced, killing everything except the saved (Noah and family) in one day! You will find the same reaction on nature’s destruction during the eruption of Mt Saint Helens in the 80s. “Piles of bones…at the boundary” only tells me things happened in one day!
This is a lie, they were kill by space lighting and it happened less that 10,000 years ago.
Good theory. Try again though. Doesn't account for Dino bones in museums needing to be covered in lead paint due to high radiation levels. What causes high radiation? Do your own research people. I'm not even gonna get into it here.
I believe God has the dinosaraus well kept safely in the planet Venus for their work on earth is over.
Such a beautiful documentary. <3
It is strange how quickly we became intelligent and no other animals come even close.
everything has a being and an end
Emotions rhyme physically linguistic interpretations pertaining to.
Dinosaurs are fake
Hi is this the cafe?
5yrs ago. Ok explains why this is all faked and just a money making machine for these folks. Pushing the narrative, pushing the lie.
IMO, there is no evidence that a meteor exterminated the dinosaurs. After all, they could have gone extinct 1,000 years before 10,000 years before 100,000 years before – or several million years before the meteor impact occurred.
4:59 NONSENSE
ALL LIES!. MILLIONS OF YEARS AGO… HA HA HA MILLIONS!!!??? LOL!!! WAKE UP! SLEEPING FOOLS..
Almost 4 hrs?…i dont have the patience…nor the time…
Fossils did
Not made over millions of years. When most things die on this planet they don't fossilized i
They get consumed. by either another thing or micro orgasm even bones if left exposed will be consumed that is Common Sense 101.. we don't have billions of fossils over billions of years they were made in a flood.. even the things that consume other things are all fossilized are together that it seems are fossilized their billions of them. just like the man said he destroyed all things at one time that makes sense they all got fossilized no to eat them not even a micro microorganism. Now that's a theory that probably will be proven true as in most theories in science at all but most eventually get proven wrong
if you say so, …all from your own imagination.
There is aGod inindia called Shiva
She is god of distroyer to creat new life
Anyone prehistoric survivors could devolve or evolve into the modern animals we see. A great white that works out and is well fed can be a modern megalodon? Or does it need mutations and gene engineering?
MAN WAS CREATED AS HE IS TODAY,,,,,,PROVEN FACT
This is a good show, but come on — it took you just over 4 minutes to start the evolutionist preaching! You know the new rules say 90 seconds.
No meteorite killed dinosaurs & they certainly wasn't around millions or even a few hundred thousands of years ago.
makes a good movie
They try to solve the mystery what could cause this sedimentary layers with fossils and fish inside. Maybe a flood? No way it was an asteroid,because they found tiny asteroid dust particles inside and they could even figure it's size from it…???
Excellent educational video. I can recommend this to anyone.
I love these made up fantasy bed time stories ??
I've been looking for Documentary on this Subject! ☆THANK YOU☆
SUBSCRIBED…more PLEASE?
Scientists nowadays are all about speculations and CGI's. Nothing useful that can be used in our everyday lives…
You know Your Ancestors were Badass Survivors when even an asteroid impact Couldn't keep Them down ?✋ Say Hello to the Birds ???️????
Lies upon lies!! I used to believe your crap!! Too bad you are twisting the minds of the youth and getting away with it. Just disgusting!!
Was it only the dinosours that got extict. What happened to the rest of the creatures? Where they watching the show and puting some marshmellows on the dinos. Did life start from the rocks leftover again. Lol what joke.
Only an idiot would believe this garbage.
