Hey, ready for some hypothermia?
Here are 10 extinct creatures
that’ll make your blood run cold.
看 低体温症 哈哈
See, hypothermia, haha.
Now, do you think the dinosaurs were kind of scary?
Hmm, think again!
In its time, evolution created creatures so terrifying.
They made dinosaurs look like cute little babies.
So, do you wanna find out which creatures would
have completely destroyed our world if they were alive today?
Hey, sounds like fun, right?
Then, let’s get started.
Hey, as a bonus,
we might even show you something really gruesome–
the worlds only known literate dinosaur.
But, before we give you all the scary details,
make sure you subscribe our channel,
and turn on this little notification bell.
Now you’ll always be on time for every BRIGHT SIDE hang out.
Counting down from No.10 Liopleurodon.
Yeah, this video is full of arking ten-dollar words,
but I’ll try to do my best.
Liopleurodon was a giant marine reptile
from the family of short-neck plesiosaurus.
This species lived during the Callovian stage of the Middle Jurassic Period.
喂 啥是侏罗纪？ 我怎么知道？
Hey, Jurassic means? How should I know?
Now, the typical size of a Liopleurodon
varied from 16 to 23 feet,
but the largest reached over 33 feet.
Considering their length and weight,
Liopleurodons were predators,
eating fish, squid and smaller marine mammals.
Moreover, their nostrils faced forward
which was a sign of their excellent sense of smell.
This also made them one of the best predators of their time.
And that’s still not the only thing that made them powerful.
Their long and flat flippers allow them to swim extremely quickly.
So no one could hide when a Liopleurodon decided to hunt.
Unfortunately, there are still a lot of unanswered questions about Liopleurodons.
But one thing is for sure,
you wouldn’t want to meet them during an exciting trip to the ocean.
Time for a millipede to join our list.
And it’s going to be the extinct, thank you.
This millipede lived in a territories of
current north-eastern North America and Scotland
about 315 million years ago.
This species range from almost one to seven feet in lengths.
and more around two feet in width.
Arthropleura’s body was apparently
composed of around 30 jointed segments
covered by 2 side plates and one center plate.
Unlike pretty much all the other creatures on our list,
Arthropleuras weren’t predators.
It’s simply because these creatures didn’t have strong mouth parts,
so they were entirely plant eaters.
But even though Arthropleuras
wouldn’t pose any serious danger to us,
just imagine looking down
as you felt something brush against your leg
and seeing this.
The record for the loudest scream of all time
would certainly be yours.
Luckily, when the usual moist climate started to dry out,
it was time for the Arthropleuras to go.
等等 是不是和特朗普媳妇有些像 不是 好吧
Wait a minute! Is that like first ladies? No? Okay.
Megalania, often called Megalania Prisca,
is the biggest monitor lizard you can possibly imagine.
Yup. It’s easily the largest terestrial lizard that ever existed.
The youngest of its fossils
dates back to approximately 50,000 years ago.
And if you’re from Australia,
then you probably won’t be surprised to know
that Megalanias live there before their unfortunate extinction.
But, was that really that unfortunate? Emm?
Not for us.
The length of the largest Megalanias reached around 23 feet with
a maximum weight of 1,320 to 1,370 pounds.
They were unbelievably active hunters as well.
And Megalania fossils were often found near kangaroos,
deers and other large animals of this kind.
However, there’s a little twist to all these Megalania facts
and it’s that these creatures may still be with us.
In both the 19th and 20th centuries,
there were numerous reports of people
seeing creatures that sounded
very much like surviving examples of Megalania.
There’s no actual evidence of this theory apart from those stories,
but who knows,
maybe these creatures are still roaming on earth.
Dunkleosteus became extint around 358 to 382 million years ago
during the late Devonian Period.
However, there wasn’t just one Dunkleosteus,
there were actually 10 species of it,
including D. terrelli, D. denisonii, and D. magnificus.
Do we get ten bucks for each of those? No, alright.
D. terrelli, the largest of them,
was almost 20 feet long.
Most Dunkleosteus fossils were found
南美 波兰 比利时以及摩洛哥等地
in North America, Poland, Belgium and Morocco.
The largest Dunkleosteus trellis
had a four bar linkage mechanism for jaw opening
that allow them to open their jaws completely in just 20 milliseconds.
They really didn’t have that many teeth,
but it still didn’t stop them from eating marine animals.
Moreover, there’s evidence that allow scientists to conclude
that the Dunkleosteus species
occasionally cannibalized each other as well,
just when we thought it couldn’t get any more vicious.
But what do you think, is Dunkleosteus the scary one yet?
Tell us about it in the comments below.
Ok, let’s move right along to
Jaekelopterus was a giant predatory sea scorpian
that you definitely wouldn’t want to see
during your mesmerizing diving experience.
Though if you did,
it would certainly be something you wouldn’t forget for a long time.
Anyway, after analyzing its fossil remains
scientists confirm that Jaekelopterus reach the size of nearly 8.5 feet
which makes it the larget arthropod ever.
These sea scorpians weren’t content with underwater urbs
like the harmless Arthropleuras,
they prefer to ambush fish with their spring loaded arms
and sliced them up using their claws.
That’s a true horror movie scene
that happened during the Early Devonian Age.
Well, judging from this decription,
they would very much enjoy human flesh as well.
Thankfully, the Jaekelopterus species became extinct
way before we were able to test this horrific theory.
Now, why are there still no crocodiles on this list?
Were there any scary ones?
Well, let us introduce you to the Sarcosuchus.
A distant relative of living crocodiles
that live about 112 million years ago.
And if you are scared of today’s crocodiles,
this one would make you run even faster.
These reptiles were almost twice as long
and weight up to 17,000 pounds. What a crack!
The first Sarcosuchus remains were discovered back
in 1946 in the Sahara Desert.
Paleontologist found fragments of the creatures’ skull,
vertebrae, teeth and other parts.
With time, scientists found even more fragments
that help them understand what the Sarcosuchus look like.
According to what’s known now, it has somewhat telescoped eyes
and a long snout
with 35 teeth on each side of its upper jaw,
and 31 teeth on each side of its lower one.
It’s not that hard to hunt with this type of jaw, don’t you think?
Apparently, scientists agree,
suggesting that Sarcosuchus
might have even eaten some abundant dinosaurs.
So we’ll say that modern crocodiles are enough for us.
No Sarcosuchus species, please.
Long before dinosaurs started to rule the prehistoric world,
there were other dominant predators out there called Gorgonopses.
They lived around 260 million years ago
terrifying all the smaller species of that time.
As for their size,
this creatues were about 10 ft long and weigh nearly 1,000 pounds.
Emm, doesn’t sound too scary after everything we’ve already seen today,
but that’s not all.
You might wonder exactly why Gorgonopses
became the main predators of their time,
we mean, they were basically at the top of the food chain.
It was their massive canines
that protruded almost beyond their lower jaw.
Plus their legs supported their body from below
as a pose to sprawling to their sights.
This advantage allowed them to reach a faster pace
and get to their victims more quickly.
Some theories also point out
that Gorgonopses may have been warm-blooded,
which implies having at least a little bit of fur.
However, these are still assumptions with no proof whatsoever.
But I’m not gonna argue with all gordy here.
你想要有毛 就有毛好了 拜托千万别吃我
You want fur, you can have fur. Just don’t eat me. Please.
If you can’t stand snakes,
Titanoboa would definitely have scared you to death.
It’s believed that this gigantic snake
lived in a region that’s now a part of north-eastern Columbia,
and its fossils date back to
about 58 to 60 million years ago.
Titanoboa holds this scary record
for the largest snake ever discovered,
with a total length of nearly 48 feet
and weight above about 2,500 pounds.
It would then into perspective for you,
it’s basically 4 times as heavy as a giant Anaconda.
As for its hunting habits,
Titanoboa was most probably very snaky,
coming out of nowhere and quickly biting its prey in the jugular.
Well, I’m not gonna sleep tonight.
Its possible victims could be smaller reptiles, birds and even crocodiles.
So you and I would have stood no chance against this monster snake.
But what would it be like to actually meet a snake that big?
While back in 2012,
visitors in the grant central terminal in New York city
were given the opportunity to envision this encouter,
thanks to a full-scale model replica of Titanoboa.
It has been created as a promotion for a TV show called
Titanoboa: Monster Snake
And seeing this model
definitely send chills down pretty much everybody’s spine.
No.2 is Megan Markle Europsis.
那是不可能的 开个玩笑 其实是史前蜻蜓
No way, that’s a lie. It’s just Meganeuropsis.
Hahah but I got you, didn’t I?
Most insects are pretty gross,
but at least they are small, right?
Well, not during the Permian Period.
At that time,
the Meganeuropsis species, gigantic dragonflies
were the kings and queens of everything.
They still continue to be the biggest insect of all time,
with a wing length of 13 inches
and a body length of almost 17 inches.
Now the very first fossils of Meganeuropsis
were actually discovered in France back in 1880.
Now we know way more about this species.
their hunting methods were very similar to the dragonflies of today.
The only difference
is that Meganeuropsis was able to
eat even larger organisms because of their size.
They detected their victims with their large eyes
and use the spine on their legs to get a hold of them.
However, with time,
atmosphere conditions began to change
which might have been the main reason
for the extinction of Megan Markle Europsis.
啊 对不起 但话说回来
Oops, sorry. But after all,
whatever happens happens for the best.
It would have been way harder to convince yourself
to leave your house
if you knew there were giant dragonflies flying outside, right?
Sharks are unbelievably scary,
but after seeing the Helicoprion,
the shark from jars seems like a cutie.
This unusual shark-like fish
was around 290 million years ago
生活在北美 东欧 亚洲
living in North America, Eastern Europe, Asia
and no wonder Australia’s waters.
Wow! Poor Australia just can’t catch a break here.
The most distinctive feature of Helicoprion was a circular jaw.
Now just imagine something like this coming toward you.
Man… you wouldn’t have been possible to return to the water ever again,
even if you survive the experience.
Apparently this creepy jaw operated like a buzz saw,
moaning into its prey and carving it up.
However, here’s a plot twist:
most scientists believe that Helicoprion wasn’t a shark.
Instead, they are sure,
it was closely related to the Chimeras,
a type of deep seafish.
Well, sharks are not.
Helicoprion is proved to be incredibly strong,
since they survived the Permian-Triassic Extinction Event
that killed 90 percent of the marine animals
and around 70 percent of the terrestrial ones.
But it only bought them a few million years
before their own distinction.
And that’s how evolution save us all once again.
And now, here’s a bonus.
A dinosaur that was really really really scary–
the first literate dinosaur.
Yes, a dinosaur that could actually read.
It was called the Thesaurus, that’s right.
The thesaurus was easy to spot,
always carring a book or magazine to read.
It’s ultimate downfall?
Always looking for alternative words which meant the same thing.
A T-rex alien, some food for thought.
