i love the toughness of these ancient animals so awesome

Don’t really remember exactly why the animals were bigger but I think it was because of the oxygen in the past.

Its amazing how strange but cool looking animals these are! Even tho they are deadly its still so cool!

3:00 The narrator states that Gigantopithecus went extinct about 1,000 years ago, there is no evidence for this at all. It's generally excepted that Gigantopithecus went extinct 300,000 years ago. Therefore Homo Erectus may have come in contact with Gigantopithecus , but this was long before us humans were in this area.

*Animals not extinct* Ark players: boutta tame this animals whole career

Studies has shown that the Smilodons had less bite force than modern day Big Cats. It was also shown that unlike Big Cats of today which can ravage it's pray with their teeth, Smilodons couldn't do that because their Saber Tooth Fangs were a bit delicate, you see those teeth were not round, they were kind of Oval like in shape, so if a Smilodon tried to ravage a prey using it's teeth, the chances of their fangs breaking were really high. Smilodons also couldn't turn sharp corners like Modern Day Big Cats thanks to their short tails. It was also proven that the musculature of Smilodons were not designed for pouncing, but was designed for subduing their prey, dragging down huge animals with their muscular front paws to deliver the final blow to the neck, sinking their huge fangs into their prey.

I could list the numerous scientific inaccuracies in this video, but instead I’ll point out: as an even bigger and badder apex predator, wouldn’t a megalania be the ultimate gigachad relative for a Komodo dragon? Instead of someone they’d be ashamed of.

Pteradactyls were not dinosaurs They were flying reptiles who evolved separately from dinosaurs

Well, Megapiranhas are really some extraordinary animals. Not only could they travel 55 million years back in time to hunt Tyrannosaurus, no, they could also swim hundreds even thousands of miles out of their freshwater rivers, wich is vital for them, into the salty ocean to hunt the Megalodon, the biggest carnivorous shark to have ever existed. Yeah, truly amazing animals!

Ringworm isn't a worm, it's a fungal infection.

That One Guy in Every Discussion Thread: "Or are they?!" My heart goes out to Edestus. Or as I will call it, the "Pog Shark" based on this image 4:06.

It's sad that humans are responsible for a lot of animals going extinct

I think that there are still things out there that we have not seen yet the sea has more than we know keep looking. More thing out there you will see

I am not at all happy that they are extinct!☹

Props to the cameraman who went back in time

The Komodo dragon still alive

Hallucigenia forti look like the the creature that turn Ymir into the first founding titan, I think so

Sure does make modern day animals look cute and cuddly doesn't it

The Phoberomys Patterson looks like they'd be super chill, just like a giant Capybara, the world's most chill mammal

It's pretty wild to think about how much the world has changed throughout it's existence. I wonder how the wildlife will continue to evolve once people are gone.

It's sad when any creature goes extinct, unless nature is the cause

"Have you ever thought about worms with legs?" No....no i don't

Just love your videos. Sort of locked down due to heath. Great video's. Thank you

Scheich, Papo and Modjo have GOT to make toys of these!!

How about my favorite: the Gorgonapsid. A formidable protomammal from before the Permian/Triassic extinction event.

2:20 when you get too addicted to anime and mistaken this creature for the one who made the first founding titan

They would all be in danger by us if they were still alive

I like how you pronounce all these extinct names that are hard to pronounce so easly

I gotta start playing ARK again! A game where you can swim with trilobites, chill with a stego, ride a raptor, tame a dire wolf, and even encounter a dragon.

All of those monsters just devovled into what we see today

I love the idea that if we planted a ton of trees we could all be towering chads

13:19 Megapiranha "was known to go after Megalodon or T-Rex", my goodness where do I start. T-Rex was a land animal weighing over 10,000kg, so it's unlikely they could ever cross paths, but more importantly T-Rex died out 66 million years ago, the Megapiranha lived 8-10 million years ago. Finally they weren't "easily 3 feet (90cm) long" they were about 70cm long. Ref en.wikipedia.org/wiki/Megapiranha

As a species, we are terrifying and have caused so much destruction. But without our weapons we obviously wouldn't stand a chance against some of these animals.

From all of this species only deinosuchus argentavis titanoboa and phourassuhus were scary. But really good video!

2:17 if that thing still alive today we can seeing rumbling and 80% population on earth are vanished

3:49 Yo it’s a Talonflame

You said: "megalodon went extinct about 3.6 million years ago." But also said "the arcdotus was native to America, California, until about 11,000 years ago." & "They went (extinct) probably around the same time as megalodon." 3.6million years That's a huge gap between the two animals.

Can someone list the movies some of these videos was extracted from? I know of only ice age and jungle book but will like to watch others.

The animals were larger because there was about 16% more oxygen in the air. I'm not 100% positive about 16% it could be 18% too 28% Anyways a study was done on some insects with higher oxygen in a sealed case with the same in insect in the air we have now and the higher oxygen insect growth was 72% larger. And thats not adding the cold Blood to warm blooded factor.

The reason why prehistoric animals are so large Is because of how much oxygen was on earth back then And oxygen Is one of the inportant factors for growth

Even though there are super deadly creatures I would probably be okay if they were still alive

Animals were many massive in size because there were a lot more oxidant in the atmosphere

I just find it fascinating about what was around millions of years ago 😊

I want many of them back🌿

4 ever green : look at this prehistoric monster Me who plays ark: I'm 3000 lightyears ahead of you

Hmmm, to be fair, a lot of these animals are just really cool and no reason at all to wish to never see them again. Like thMeganeura or the Hallucigenea Forti or the Anomalocaris. They all are such cool animals, yet you present them as if they were nothing but detestable. Come on, those shouldn't be on this list!

Scientists- We don’t exactly know when the last megalodon went extinct Me- Then how do you know it’s actually extinct

awesome video

3:02 It went extinct around 100,000 years ago. This channel is really sketchy, getting all these facts wrong.

Guess who's actually alive to terrorize the living? Hippos. Even crocodiles won't mess with them.

Imagine if the "Terror Bird" could mimic the Voices of their Preys before they died..😱

props to the camera man for recording this much extinct animals

8:07 its argentavis and thats a velociraptor

Extinction is awesome Still missing so many more

all of your movies are amazing 👏

I love nature 😊

Its sad to see people who are afraid of those creatures and just refuse to apreciate them as what they trully are Animals, beaultifull animals that we are unlucky that we will never ever have a chance to see Even if the creatures in this video are "scary" we should apreciate them just like we apreciate animals nowadays and not just fear them

I think all of the land mammals (not bugs or sea creatures) were adorable! I love 4ever green's dialogues! They all were hilarious. I loved this video and the snakes and the birds! I'm obsessed with giant snakes and humongous birds! Oh, and prehistoric animals so this was the PERFECT video for me!

Arctodus for last appropriate ..nice show thank you

This is awesome 👌🏿

4 True Green: *Talks about a giant rat* Me: That looks like a capibara

It's true about the Dunkleosteus being able to open and snap their mouths shot in a matter of milliseconds, not only that but their teeth, were not teeth, but somewhat a part of their armor, and they were like blades. They were basically slightly smaller than a Megalodon.

Very Nice Videos

Your support is like a virtual hug. Sending gratitude your way!

I believe he neglected to give the actual size of the titanokorys gaines. FWIW, it's 1.6 feet (according to Google).

I want all of these as pets...

4:52 thats a capybara

Fun fact the ring worm is not an actual worm but rather a type of fungi

Thumbnail pic: That's a "Shovel-Tusker", or, as I called them as a kid, an "Elephant Pig"!

I can appreciate the past, but it's the future that sometimes gives me the willies.

The giant insects were probably the scariest creatures to ever walk the earth just imagine a scorpion or millipede the size of a car holy gwaka moly

Animals are always important.Even if there wild,we still need them to live.Extinct animals are important.We should not get happy there extinct.İmagine life with no animals,it would be so bad.We humans should not hunt these animals.İf they live,they deserved to live in there own spot.

It makes me mad for the fact people say sea creatures are instinct but they don’t know the whole ocean

1:39 when I was 5 I saw a 2 foot long dragonfly on my car maybe it’s closer related

One of my favourites is: Paraceratherium, such a big one.

What are the movie credits? I’d like to see some of them. Esp the one with the mammoths.

I think you meant “Sabertooth” as the smilodon because smilodon I don’t think exist

And that some lived millions of years ago but really good work

Definitely glad that Titanoboa and Andrewsarchus are no longer around. And that's just on land! I'm not particularly comfortable swimming in the ocean as it is, but I'd absolutely refuse to go near them if Carcharodon Megalodon and Mosasaurs still existed.

2:51 Founding Titan º _ º

I Kinda feel bad for the Smilodons. They look very fluffy. I wonder what it would be like to have one as a pet? Would it just devour me when given the chance? I am actually super curious now.

I like it. It's very useful

My favorite animals is megalodon shark

I love dinosaurs I am sad that they don't live now

This was amazing!! Thankyou so much! I love to see updated fossil finds. And some of the dinos have the new fur looks!

Phoberomys patterson looking like a capybara

This was so fascinating!!! I love seeing videos like this!!!! 🤩🤩🤩

They put in Deinosuchus but not Sarcosuchus, I'm hurt. I mean the difference between Deino and Sarco is that Deino had a thicker snout and jaw while Sarco's Snout was long and Narrow, also Deino had more weight than Sarco and while both ambushed Dinosaurs when they come close to water, Deino had the stronger bite force than Sarco thanks to it's thicker, shorter snout and jaws.

For almost any viewers from outside the USA, it would be helpful if you also told the metric measurements, because most non-US people don't know how much e.g. "6 feet" is.

These are all really cool

Love your video

1. Smilodons were not as big as portrayed in this video. Scientists are pretty sure they developed the large Canine teeth so they could kill much larger prey animals by biting through their neck vertebra. Not to say they wouldn't turn down an easy smaller animal. According to scientists who's work I've studied they were no bigger than a regular Bengal Tiger and thus smaller than even a modern day Siberian Tiger. That one a 1:21 is about twice their largest size. One final note, there were actually 5 different species of sabre toothed cats, none of which co-habitated the Earth with each other. it worked like this: Big prey animals would evolve, Sabre tooth cats would evolve to eat them. Big prey animals die out as the cats eat them all, then the cats starve. Rinse, repeat several more times. Oh never mind. Nothing I've seen so far is even close to accurate. Bye Bye.

This was a awesome video. I'm so happy these animals aren't alive anymore. ;)

I like that you have the titles of the different videos you included in your video! Like citing your sources. Very cool. Thank you more stuff for me to check out

I'm not glad they're extinct. Wanting a whole species to die out is really messed up.

Fun fact:Scientists are working to bring back smilodon and wolly mammoth

Fun fact: *megalodon is still here in 95% of the ocean*

I like it 😁😁😁

i LOVE your videos

Early humans were also stronger and fiercer
