Starting off at number 10 we
have the Megalodon.
Megalodon was the biggest shark that ever lived.
They went extinct 2.6 million years.
Scientists think they could have grown to an insane 60ft in length - thats about 3 times
as long as the largest Great White shark ever found.
Heres how big they are - before modern science identified them as a prehistoric species of
shark - people used to think that Megalodon teeth theyd found were dragon tongues.
Others said they belonged to giant serpants or even that they were rocks that had fallen
from the moon.
Think how big and scary youd have to be for people to think your teeth belonged to dragons
or outer space.
It used to feed on prehistoric whales and unlike modern sharks which go for the soft
underbelly of their prey, Megaladon just went for it.
They would bite down on the whales chest with some 41,000 pounds of force , the strongest
ever recorded, and simply crush the whales chest cavity and organs.
They didnt stand a chance - and unless youre an even bigger whale watching this video - you
probably wouldnt either.
Next up at number 9 we have Phoberomys Pattersoni.
This was a huge rat - some scientists have even called it Ratzilla.
Technically it wasnt a rat but if youre scared of them - I bet youd be scared of this.
They reached a whopping 9.8ft long - their tails alone could reach 4.9ft.
They had the weight to go with it too - often reaching over 1,500 pounds.
Like most rodents, they had big incisor teeth - in this case of Ratzilla though - their
incisor teeth were about a foot long.
Its a good job they were herbivors and used those teeth for plant life - however - I don't
think that knowledge would do much to calm people if they were suddenly seen running
around the streets at night …
Coming in at number 8 we have the Titanoboa.
Everyone with a phobia of snakes, look away now.
This was a giant snake thought to actually be the largest thats ever lived.
Its name literally means titanoboa.
It lived around 60 million years.
The largest individuals reached up to 42ft in length and weighed over 2,500 pounds - thats
well over a ton - for a snake.
They could grow this big because the Earths climate was a lot warmer back then.
As the climate began to cool over the next few million years, only smaller snakes could
survive and snakes like the Titanoboa began to disappear.
Probably a good thing for us humans as we would not want to be running around worrying
about snakes that weigh as much as your average Rhino - no thanks.
Next up at number 7 we have Dunkleosteus.
This is a fish that lived about 370 million years ago during the Late Devonian period.
These things were big - growing up to 30ft in length and weighing over a ton.
Whats most scary about them is their bite.
This fish could bite down on its prey with a force of some 6,000 newtons - that might
not mean anything until I tell you thats almost 4 times the bite strength of a polar bear.
This fish could bite your arm clean off you - including the bone.
Its jaws were so efficient they could hinge them open and snap them shut in a matter of
milliseconds.
If we were to bring this species back to life - people might worry about them more than
sharks …
Next up at number 6 now we have the Megapiranha.
Unlike a lot of scientific names on this list - the Megapiranha has a kinda obvious one.
It was a giant Pirahana fish that lived 10 million years ago.
They grew to around 3ft long and unlike modern piranhas they had not one - but two separate
rows of teeth.
Scientists arent even sure how hard they could bite but some estimates go as high as 4,749
newtons - if thats the case, they would bit more than twice has hard as a Hippo.
Neither of those sound fun - once definitely sounds worse though.
Moving on to number 5 now we have Gigantopithecus.
In many ways - this creature is what wed call bigfoot.
It lived between 9 million to 100,000 years in Asia and was the largest ape on Earth.
They stood about 10ft tall and their diets were most likely vegetarian.
When I say stand, I mean stand in the way Gorillas and Chimpanzees do - its thought
they walked on all fours.
However, a small number of scientists do think they walked on two legs like humans.
Either way, with a 12ft arm span - you be best to stay clear of this giant and unpredictable
ape.
Next up at number 4 we have Helicoprion.
This was a shark like creature that lived some 290 million years ago during the early
Permian era.
Weve seen some weird creatures on the list so far but this might just beat them all - the
Helicoprion is famous for his spirally arranged clusters of teeth known as -tooth whorls-
… this bizzare set of teeth would have reached 24 inches in length.
Moving on to number 3 now we have The Short Faced Bear.
The scientific name for these is Arctodus.
They first appeared in the fossil records 1.8 million years ago and seemed to survive
all the way up until just 11,000 years ago.
So, a pretty close call for us modern humans.
One specimin found weighed 2,110 pounds.
They stood up to 12ft tall on their hinds legs - about twice the height of the average
human male.
Their vertical arm reach extended up to a further 14ft.
I could keep giving you stats on just how monstrous these bears were but between those
ones and the pictures youre seeing - I think you get the idea.
They were 50 percent larger than the biggest polar bears in recorded history.
Scientists estimate they needed a whopping 35 pounds of bet a day just to survive.
If we brought them back, Im sure they wouldnt mind human meat being a part of that.
Next up at number 2 we have the Meganeura.
Dragonflies are nice right?
Theyre pretty cool looking creatures you find fluttering around ponds and rivers.
Theyre a little bit freaky if they land on you on you though but hey - at least theyre
small - not Meganeura though.
This massive dragonfly lived about 300 million years ago during the Carboniferous period.
Its wingspan could reach up to 30 inches - making this thing about the size of a 6 month old
baby.
Don't ask me why Im using a baby as a reference, its just the comparison I found.
They reached this size because insects need more Oxygen the bigger they are.
Back then, the Oxygen levels in the atmosphere were higher than the current 20% we have today.
This allowed insects, including Meganeura, to grow insanely big.
You wouldnt need a hand to bat thing away - more like a baseball bat.
And finally at number 1 now we have Deinosuchus.
This is an extinct relation of the modern alligator that lived some 80 to 73 million
years ago.
That means it was alive at the same time as Dinosaurs such as the T Rex - infact - its
thought these two actually fought it out back then.
They are thought to have been up to 33f in length and have weighed as much as 5 tons.
It looks like the T Rex might not have been much of a match for this oversized alligator.
There have actually been T Rex fossils found with massive Deinosuchus bites found in them.
Perhaps they were just defending their territories from T Rexes or perhaps they saw them as food.
Either way, they definitely were not scared of T Rexes and so would not be scared of us.
I get the feeling if we brought them back from extinction - that might be where were
heading next …
Im just kidding of course - humans would probably be fine - this whole video was just a fun
thought experiment that I hope you enjoyed.
Now its time to go over some of your comments, this is from my Top 10 Scary Rooms That Should
Have Stayed Secret - Part 2.
The first comment comes from Investing Hustler who says -I would actually love to visit these
places- … really?
Some of those places sounded horrific - the first one was literally just a room with a
dead cat and demonic message written on the wall - why would you ever want to visit those
kind of places?
Unless youre the one who leaves those kind of messages behind …
Banter In The Fast Lane said -An hour and not a single dislike yet.
Never seen that on YouTube before- don't say that!
As soon as you say that, someone will see it and theyll dislike - not even because they
dislike it - but just because they want to be special - they wanna be that one person
who will dislike the video!
So next time you see that, just keep quiet … maybe smile at the screen and nod.
Nothing more though.
Waffle Bot says -Lol Barry Benson got a new job as a host- … I had to look up who Barry
Benson is - its the main character from The Bee Movie.
How do I look like a bee?
He has brown hair which I don't and blue eyes when I have green eyes - so wheres the resemblance?
Am I bright yellow with wings?
Ive just realised that people are saying that because I was wearing my stripey yellow shirt
- well, thats a relief - I was worried I was turning yellow and growing wings.
