We talked about animals that are no longer with us - scary animals that could rip us
to shreds or crush us without even realising - I thought it might be too much for some
of you but I was wrong, the comments were just full of people asking for more.
I think our subscribers are a bit crazy, and I love it, I am too - my names Danny Burke
and this video is the Top 10 Extinct animals we shouldnt bring back to life part 2!
Starting off at number 10 now we have Spinosaurus.
Let me start by asking you a question - whats the largest carnivorous dinosaur of all time?
Surely the T rex right?
Theyve always been portrayed as the top dogs … their name literally translates to tyrant
lizard king.
I was surprised to learn that its actually the Spinosaurus is the perhaps the largest
known carnivorous dinosaur of all time.
It lived about 100 million years ago.
Estimates put the length of these things at about 60ft while weighing as much as 23 tons
- thats 3 and a half times as a T Rex.
If its sheer size wasnt scary enough - you might have guessed from its name that it also
had spines.
They fanned out across its back and formed what is usually referred to as its sail.
What scientists arent sure about is if the spines were covered in fat and looked kind
of like a huge camel like hump.
If a camel was the size of a small building.
Coming in at number 9 now we have The Giant Crocodile.
Thats right, if you thought the best way to make a crocodile even more scary was to give
it more teeth - youre wrong - you just make them away bigger - and they really did exist.
The scientific name for this animal is Sarcosuchus.
They lived around 112 million years ago during the early Cretaceous period in what is now
Africa and South America.
These things weighed about 8 tonnes and grew up to 40ft in length.
Thats almost twice as long as the biggest living crocodiles today.
The Giant Crocodile would laugh at the crocodiles we have today.
Then it would eat them.
Then it would eat us.
Then it would laugh.
Luckily, they died out over 100 million years ago.
Next up at number 8 we have The Walking Worm.
The scientific name is Hallucigenia Fortis.
It was part of a family of walking worms.
They looked like worms, they acted like worms - but they had legs - actual legs.
Get this - scientists discovered their fossils in Canada and China - they were so weirded
out by their appearance, they called them Hallucigenia, as in Hallucinogenic, like hallucinogenic
drugs.
These things are so weird looking, the scientists basically thought they were tripping out - thats
what Im taking from it.
Im thinking if normal worms creep people out, then a big walking one that looks like it
came from a Harry Potter movie might be a bit too much …
Moving on to number 7 now we have Andrewsarchus.
Think of a big scary mammal.
A lion?
A tiger?
A bear?
Oh my.
This thing would eat them for breakfast.
Andrewsarchus lived in what is now China about 45 million years ago.
The only known skull of this creature was discovered in Mongolia in 1923 - its now on
display in the American Museum of History in New York.
It was from only this skill and a few bones that scientists were able to make an accurate
construction of what this beast would have looked like.
When they finished the model, they were pretty shocked to see that it would have weighed
about 4,000 pounds - that would possibly make it the largest land-dwelling mammal predator
ever.
Were talking bigger than all the lions, tigers and bears oh my.
If you don't want to step into a ring with them, well those creatures wouldnt want to
step into a ring with this …
Next up at number 6 we have The Pig from Hell.
Again - thats my name, youll see why though.
This mammal is known as the Entelodon.
They lived 37 - 28 million years ago across Eurasia.
If we were around back then, we would have said they looked like pigs - but terrifying
ones.
Despite being on all fours, these things were 4 and a half ft tall.
They were massive.
Some scientists say they had a ravaging appetite for meat.
These things would eat you, theyd eat me and if there wasnt any other meat around - theyd
eat each other.
You heard me right.
Some have suggested that Entelodonts were cannibalistic - they craved meat so much,
theyd even eat their own kind.
How does that sound then?
Imagine one of these charging at you … you wouldnt stand a chance.
You better hope theyve eaten their fill for the day, or youll be the filling - that sounds
weird.
Moving on.
Next up at number 5 we have The 3ft Long Scorpion.
Thats the scientific name.
Kidding - this is Pulmono-scorpius.
It looked just like modern scorpions, it had the same front claws and sting in its tail
- the only difference is this thing was bloody massive.
It lived over 300 million years ago during the carboniferous period and this helps explain
why they grew so big.
Back then, Earths Oxygen content in the air was a lot higher.
Scientists know that this is one of they key factors in determining how big some creatures
get.
So, if you don't like creepy crawlies - just be glad there isnt too much oxygen in the
air.
We know this creature had venom, like many modern scorpions, but its difficult to know
just how toxic it would have been.
One things for sure though, you wouldnt wanna stick around these things to find out - if
modern day scorpions cause problems for us today, imagine these 3ft versions running
around stinging us.
No thanks.
Moving on to number 4 we have the Smilodon.
I love this one.
I remember watching a show as a kid called Walking with Beasts that featured this animal.
Check it out if you havent heard of it - probably came out before some of you were born.
The Smilidon lived from 2.5 million yeard ago to just 10,000 years ago.
If you recognise the picture on the screen right now - you may know this creature by
its much more famous name - the Saber Tooth Tiger.
They were a forced to be reckoned with with - well built forelimbs and exceptionally big
canine teeth.
They spread all over the world and came in a number of different types.
The biggest ones are thought to have weighed up to 880 pounds!
You might think oh well Im glad humans never had to live alongside these beasts - well
think again, they did.
Considering the Saber Tooth Tiger didnt died out about 100,000 years ago, there were already
modern humans just like me and you, walking around.
Many of them got probably got eaten by these big cats as they had nothing more than a spear
to defend themselves.
They died so that we could live, I vote that we don't bring them back.
Next up at number 3 we have the Terror Bird.
Thats the nickname given to Phorusrhacidae - and I think the nickname suits it well.
They were the largest species of apex predators in South America for about 60 million years,
starting 62 million years ago.
Thats a very long time.
You can even picture how long these things were the top dogs for.
They were huge, standing up to 9.8ft tall.
They were flightless too, thats quite strange to think about - we usually think of flightless
birds as quite harmless - dodos and penguins, maybe Ostritches could give you a good slash
but generally speaking, its the flying hawks and things that are the scariest.
This creature will make you think twice though.
The terror birds were big, they weighed up to half a ton.
OK, so you might be able to outrun them?
Well probably not, its thought they could run as fast as a cheetah - thats about 75
mph.
If you see a terror bird and the terror bird sees you - just give up.
Accept your fate as its lunch.
Coming in at number 2 now we have The Giant Bird.
Thats my name for it, the real name for this creature is Pelagornis Sandersi.
It is one of the largest flying birds ever discovered.
It lived 25 million years ago during the Oligocene era.
This thing - was huge.
You may think youve seen a big bird, maybe bit pigeon or a seagul - nah, youve not seen
a big bird, look at the side of this.
Pelagornis Sandersi had a wingspan of up to 24ft - its wingspan, was bigger than a Giraffe
is tall.
Just picture that.
Perhaps fittingly for one of the largest flying creatures to ever live, the only fossil of
this creature to ever be discovered was found in 1983 by construction workers at Charleston
International airport, South Carolina.
Big bird, found at an airport?
Yeah?
Interesting link?
Well, it seemed like it was earlier, perhaps its not anymore …
And finally at number 1 we have the Quetzalcoatlus.
Im not even sure how to start off with this one - just look at this thing.
This creature was a pterosaur, they lived alongside dinosaurs, but were very much their
own thing.
This Quetzalcoatlus was one of the largest known flying animals of all time.
It was toothless, it had a long stiff neck and was just generally a bit of an odd ball.
Its wingspan was 52ft.
Remember the massive bird we were talking about earlier?
This creature had a wingspan twice that size - its hard to even imagine how big this thing
was.
Ever since its discovery, people have been fascinated by it.
Its been features featured in documentaries and movies.
Perhaps my favourite one is Clash of the Dinosaurs.
We already know thats wrong anyway but wait till you hear this - the show portrayed them
as having ultraviolet vision to locate dinosaur urine while hunting in the air.
I laugh but I kinda wanna watch it …
Well they were some scary animals - are you glad they don't exist anymore?
Or have I done the opposite, maybe you think theyre really cool and you wish they were
still around!
Let me know your thoughts - let me know if you want a part 3 there are thousands of extinct
species we can talk about - thanks as always for watching my name is Danny Burke and Ill
see you all in the next video.
