Nice arms, loser.
00:03
Speaker A
I may have spoken too soon.
00:06
Speaker A
Turns out almost everything you think you know about dinosaurs is wrong.
00:10
Speaker A
Everybody loves a joke about how T-Rex had weak, puny arms.
00:14
Speaker A
But what we found is that these things were ridiculously ripped.
00:17
Speaker A
Sure, they were only three feet long, roughly the size of your arm, but they were still packed with enough muscle to curl over 400 pounds.
00:25
Speaker A
So obviously, these Sam Sulak-looking arms weren't useless.
00:29
Speaker A
But that's just one of the many dinosaur lies you probably still believe.
00:33
Speaker A
And in this video, I'm going to go over 13 of the biggest.
00:37
Speaker A
And this next one is one you've probably fallen for.
00:40
Speaker A
You ever go on TikTok and see something about how Spinosaurus sounded like this?
00:44
Speaker A
So that's not how they sounded at all actually, because that's just a loon call slowed down.
00:49
Speaker A
In fact, every single dinosaur noise you hear is total BS.
00:53
Speaker A
Truth is, we have no idea what most dinosaurs sounded like.
00:58
Speaker A
Except one.
00:59
Speaker A
Parasaurolophus.
01:01
Speaker A
You see that giant crest sticking out of its skull?
01:03
Speaker A
Well, it was filled with tubes and airways.
01:05
Speaker A
So scientists 3D modeled it, pushed air through it, and it sounded like this.
01:55
Speaker A
Oh yeah, I'm 99% sure this dinosaur sounded like an air horn.
02:01
Speaker A
Pretty cool nonetheless.
02:02
Speaker A
Then again, that's not the only lie you've been told by media.
02:08
Speaker A
Yeah, that's just totally wrong too.
02:10
Speaker A
T-Rex had the biggest eyes of any land predator.
02:14
Speaker A
And I know size isn't everything.
02:17
Speaker A
At least that's what I tell myself.
02:20
Speaker A
Though for T-Rex, it did actually make a difference.
02:24
Speaker A
Its vision was estimated to be up to 13 times sharper than yours.
02:27
Speaker A
With forward-facing eyes and incredible depth perception, if you were in front of it, even from miles away, it was going to see you.
02:32
Speaker A
But the real question is, what would you see if you were looking back?
02:35
Speaker A
Because when most people picture a dinosaur, they think of something scaly like a crocodile.
02:40
Speaker A
Except crocodiles aren't even that closely related.
02:43
Speaker A
Their actual closest relatives are birds.
02:46
Speaker A
Because dinosaurs never really went extinct, only the ones that couldn't fly did.
02:50
Speaker A
So get that myth out of here.
02:52
Speaker A
A weird fact, but that does technically mean that birds are reptiles.
02:57
Speaker A
So then, if all birds are dinosaurs, does that mean all dinosaurs look like birds?
03:02
Speaker A
No.
03:03
Speaker A
Birds evolved from theropods.
03:05
Speaker A
But that's just one of three branches on the dinosaur family tree.
03:10
Speaker A
Which means while some dinosaurs definitely look like birds, which we could see preserved in fossils and even trapped in amber.
03:16
Speaker A
We also know others look totally different.
03:20
Speaker A
Sauropods probably didn't have feathers.
03:22
Speaker A
T-Rex had scales over most, if not all of its body.
03:26
Speaker A
But it gets even weirder.
03:29
Speaker A
Some species, like Ceratopsians, had quill-like structures on their tails.
03:34
Speaker A
So, the whole feathers versus scales debate, just throw it out the window.
03:37
Speaker A
But you know what wouldn't fit through a window?
03:40
Speaker A
A dinosaur.
03:41
Speaker A
Because they're all massive, right?
03:44
Speaker A
Not exactly.
03:46
Speaker A
The smallest dinosaur we've ever found is a bee hummingbird, which is like two inches long.
03:50
Speaker A
Though, if we're talking non-avian, you got stuff like Microraptor.
03:54
Speaker A
About the size of a crow and barely a couple pounds.
03:58
Speaker A
We got really lucky with Microraptor too, it lived in the perfect environment to fossilize.
04:02
Speaker A
And some are so well preserved, we even know its feathers were black, and if the light hit it just right, they'd shimmer blue and green.
04:08
Speaker A
And this thing lived over 100 million years ago.
04:11
Speaker A
But here's the thing.
04:12
Speaker A
Most dinosaurs didn't live in conditions like that.
04:15
Speaker A
Now, say you've got some pinky-sized bone from some tiny dinosaur.
04:19
Speaker A
And an eight-foot femur from an Argentinosaurus.
04:22
Speaker A
Which one's more likely to survive 70 million years underground?
04:27
Speaker A
Exactly.
04:28
Speaker A
That's preservation bias.
04:30
Speaker A
Big bones fossilize better, so we find them more.
04:33
Speaker A
But that also means we're probably underestimating how many small dinosaurs there really were.
04:38
Speaker A
And considering we've probably found less than 1% of all dinosaur species.
04:43
Speaker A
Who knows what else is still out there?
04:48
Speaker A
Even so.
04:50
Speaker A
Dinosaur fossils are a lot less rare than most people think.
04:54
Speaker A
As long as you're in the right place.
04:56
Speaker A
This is the Hell Creek formation.
04:59
Speaker A
And if you know what you're looking for, you can literally walk for a few minutes and find a fossil.
05:05
Speaker A
How complete they are?
05:08
Speaker A
That's a different story.
05:10
Speaker A
When your average dinosaur dies, it probably gets scavenged.
05:12
Speaker A
So finding one that didn't get eaten, but also got perfectly buried, and then stayed intact while the earth shifted for millions of years, that's the miracle part.
05:24
Speaker A
And something you might not realize is even with the dinosaur fossils we do have.
05:29
Speaker A
They're embarrassingly incomplete.
05:32
Speaker A
I mean, for God's sake, I made an entire video about the life of Quetzalcoatlus, and all we have is a single arm bone.
05:40
Speaker A
If you were listening closely there, I just made the cardinal sin of paleontology.
05:45
Speaker A
Thinking every prehistoric animal was a dinosaur.
05:49
Speaker A
However, a lot of those animals weren't dinosaurs at all.
05:53
Speaker A
Let's start with the ocean.
05:55
Speaker A
Ichthyosaurs, Plesiosaurs, Mosasaurs.
05:58
Speaker A
Not dinosaurs.
06:00
Speaker A
They're part of their own weird aquatic branches on the reptilian family tree.
06:05
Speaker A
Same with the ones in the sky.
06:07
Speaker A
You've probably heard the word Pterodactyl.
06:10
Speaker A
But that's actually not the right name.
06:13
Speaker A
That's just one species of a much bigger group called Pterosaurs.
06:18
Speaker A
And they were flying reptiles.
06:20
Speaker A
Not dinosaurs.
06:22
Speaker A
Speaking of animals that aren't dinosaurs, let's talk mammals.
06:26
Speaker A
You always hear that mammals back then were small, helpless, and lived in holes in the ground.
06:31
Speaker A
But some of them.
06:34
Speaker A
Actually ate the dinosaurs.
06:37
Speaker A
This is Repenomamus, a badger-sized mammal that we know for a fact.
06:41
Speaker A
Had a taste for dino meat.
06:44
Speaker A
Because one fossil was found with a baby Psittacosaurus in its stomach.
06:49
Speaker A
And this wasn't just a one-time thing.
06:53
Speaker A
In another fossil, it's straight up mid-attack, latched onto another Psittacosaurus's rib cage.
06:59
Speaker A
So, some mammals were already out here devouring dinosaurs long before we turned them into nuggets.
07:05
Speaker A
But that doesn't mean dinosaurs were somehow losing.
07:08
Speaker A
There's this idea that mammals took over because dinosaurs were slow or outdated.
07:12
Speaker A
That couldn't be more wrong.
07:15
Speaker A
Dinosaurs were some of the most well-adapted animals to ever live.
07:20
Speaker A
Ruling the Earth for over 165 million years.
07:25
Speaker A
Nearly three times longer than mammals have.
07:29
Speaker A
In fact, they were around so long that we live closer to T-Rex than T-Rex did to Stegosaurus.
07:36
Speaker A
So, no, most of your favorite animals sadly wouldn't have met.
07:41
Speaker A
Unless they tripped over each other's fossils.
07:44
Speaker A
And yes, dinosaurs were actually more advanced in a lot of ways.
07:48
Speaker A
Especially their breathing.
07:50
Speaker A
While mammals breathe in and out through the same lungs.
07:55
Speaker A
Dinosaurs and modern birds have a totally different setup.
07:59
Speaker A
They have air sacs spread throughout their bodies, which keeps fresh oxygen flowing through their lungs even while exhaling.
08:05
Speaker A
In fact, dinosaurs' overspecialization may have been part of what led to their downfall.
08:10
Speaker A
While our smaller, more adaptable generalist ancestors were able to cling on.
08:16
Speaker A
And yet, despite all their advantages, their entire existence supposedly ended in a single afternoon.
08:21
Speaker A
An asteroid hits Earth and boom.
08:23
Speaker A
Dinosaurs gone.
08:25
Speaker A
Well, we already know that's at least a little wrong.
08:28
Speaker A
Because.
08:30
Speaker A
And even for the non-avian ones.
08:34
Speaker A
They didn't vanish overnight.
08:37
Speaker A
It might have taken decades, maybe even thousands of years.
08:40
Speaker A
For the last of them to die out.
08:42
Speaker A
Look at the mammoths of Wrangel Island.
08:45
Speaker A
Most mammoths went extinct around 10 to 14,000 years ago.
08:49
Speaker A
But a small group survived in isolation until just 4,000 years ago, around the same time the pyramids were being built.
08:56
Speaker A
This same thing could have happened with a few dinosaur species, holding on in small pockets before eventually disappearing from genetic collapse.
09:02
Speaker A
Bad luck or another disaster.
09:04
Speaker A
But what's even stranger is that despite how it sounds.
09:08
Speaker A
This wasn't even the worst extinction Earth ever gone through.
09:13
Speaker A
Not by a long shot.
09:16
Speaker A
There was one even earlier that made the asteroid look tame.
09:20
Speaker A
And it nearly wiped out everything.
09:23
Speaker A

09:30
Speaker A
I really do read every single one, that is literally my favorite thing to do.
09:35
Speaker A
I probably waste too much time reading the comments.
09:38
Speaker A
But as always.
09:41
Speaker A
