Insects, yes, their primitive breathing system doesn't circulate oxygen throughout the body, they have openings along their body to take in oxygen. If they're too big, oxygen wouldn't reach all cells. The more oxygen is in the air, the bigger they can get.
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.
Yep, and he also stated that the megapiranha ate Trex and Megladons...(note, it was freshwater, and lived 8-10 million years ago.) I don't think that a single animal in this video didn't have at least a couple of glaring errors!
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.
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!
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

@@matthewutech5970 Hmmm. . . you know a komodo dragon can reach 10' in length, and has been known to feast on sheep and cattle, which it kills with a venomous Bite. It can be deadly, and is likely the descendant of this larger monitor.
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.
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.
1. You're correct on this size aspect. For some odd reason, people tend to exaggerate the size of many extinct mammals. Many of them were no bigger than their present day counterparts. 2. You are wrong about different species of saber-toothed cats not cohabitating with each other. Homtherium and Smilidon, definitely lived at the same time for thousands of years in the Americas. And they both went extinct around 10,000-11,000 years ago in the Americas. Different species of saber-toothed cats also cohabitated in Africa, Europe, and Asia.
Some that I caught are 10,000 B.C.,Rampage,Clash Of The Titans(2010), Hercules, Jurassic World,King Kong(2005)and Walking With Prehistoric Beasts(BBC series,I believe)...hope this helped
great video, really informative and well put together! it's fascinating to learn about these extinct animals, but part of me wonders if we should focus more on conserving endangered species that are still around rather than just highlighting what's already gone. what do you all think?
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 oxygen thing only aply to arthropods, because they have a diferent breathing system, the giant vertebrate animals usually have to do with, the amount of food available to them, some times the temperature of the ecosystem they're living in and also some adaptation such as the air sacks in dinosaurs, to make their bodies lighter and not die from overheating.
Something definitely did happen to the mammals, because many mammals from the past were much larger than mammals today. Check out a baluchitherium, an ancient hornless rhinoceros. It was as high at the shoulder as the head of a giraffe is today. The only case I know of where the modern mammals are bigger are the seagoing mammals (like blue whales). The huge, ancient mammals went extinct for some reason. It's hard to ambush prey if you're huge.
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.
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.
what an interesting video! i really enjoyed how you showcased these animals and their unique traits. but honestly, i can't help but wonder if we should be more focused on the species that are currently endangered rather than those that are already extinct. isn't it a little strange to celebrate their demise when there are still so many struggling to survive today?
this kind of footage always gives the impression a deadly creature was lurking in every nook or cranny. most predators are sparse and wide distributed and how many people living in the area where cougars excist see them on a daily basis? Hardly anyone.
@@smonkeyfunkid5980 If they existed, I'd love to have a pet titanoboa, except, it would probably eat me on a dime, and also cost a fortune to sustain lol.
really enjoyed this video, it was super informative and nicely put together. but honestly, i can't help but think that the extinction of these animals, while sad, might have opened up opportunities for other species to thrive. sometimes nature needs a little reset, right? what do you think?
what an intriguing video! i really appreciate the effort that went into showcasing these extinct animals. however, i can't help but wonder if sometimes we focus too much on the fear these creatures inspired rather than acknowledging the role they played in our ecosystem. it's like, while it's good to learn from the past, maybe we should also be careful not to glorify their dangers when discussing their extinction. just a thought!
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
We can appreciate them and still be glad that they are extinct. Mammals were no bigger than an opossum when Dinosaurs roamed the planet as an example. You had a lot of Mammals that have tiny descendants compared to what we had then. Sloths as big as 20ft, etc. Considering how dominant Black Bears, Grizzly Bears, and Polar Bears are today, I'm glad that Cave Bears went extinct as they were far larger and more scary. I'm sorry, but Dinosaurs sharing a planet with Humans would mean that we were screwed. It would be far worse than what you saw in Jurassic Park.
@@Deadsea_1993 cave bears were less agressive and had a more herbivore sided diet. non avian dinos livig with us does not mean we are screwed, just some species woukd screw us, like carnivore theropods, while dinos like ornithomimids and dwarf sauropods could live with us
Snakes and spiders are the worst creatures on the planet. What blows my mind is that some people think eating meat is wrong but do not complain about animals eating other animals.
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!
great video! i really appreciate the effort you put into showcasing these extinct animals. however, i can't help but wonder if we’re too quick to celebrate their extinction without considering the ecological roles they may have played. what do you think?
really enjoyed this video! it's fascinating to learn about these extinct animals and the impact they've had on ecosystems. but honestly, it kinda makes me wonder if these animals were really as deadly as the title suggests. i mean, some of them might have just been misunderstood or became extinct due to human actions. what do you all think?
@@hamburgerhamburger4491 but would they hurt you if they did not go to the water?, even maybe there is a titanic sized creature in the ocean because we did not discover all parts of the ocean
i really enjoyed this video! it’s fascinating to learn about animals that are no longer with us, but i can't help but wonder if some of them could’ve actually played a role in today’s ecosystems. it feels a bit sad that we’ll never know how they might’ve adapted to our changing world. what do you all think?
I'm so glad you enjoyed the video! It's fascinating yet bittersweet to think about how extinct animals might have influenced today's ecosystems. Their adaptations could have been incredible, but maybe their absence also shaped the world we know today. What are your thoughts on the balance between nature's loss and evolution?
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.
as to your initial comment at the begininning of this video, We SHOULD ONLY work hard to ensure WE AS HUMANS do not cause the extinction of an animal/plant species. If however it is a NATURALLY occurring extinctinction event, then SIMPLY let Nature take it's course.
I have a question about Anomalocaris….something about those toothed tentacles has never looked right to me. I like the design but I’m curious how palentognists know for certain that it was hunting like it is in the clip? Those tentacles I always thought looked more like they could be being used to dig into the ocean floor to find hidden animals(it’s that scene out of walking with monsters where it’s eating a trilobite that makes me question how practical that using them for that is). I don’t know I’m not an expert and I’m probably looking at it from the advantage of a few millions years removed.
I think they have found numerous tribute remains with bite marks matching the mouth parts of anomalocaris. But over 400 million years the best the best of us can do is guess.
paeontologists never know anything "for sure". That's not how science works in general. Science only knows the truth approximately and can only talk approach it as closely as possible, but never 100%. And true science NEVER claims to do that. only people who produce youtube videos claim to present "truths".
@@fiedelmina You are right and I think I misspoke when I put the comment up originally because I was insecure and thought I sounded stupid(I think it happens to everyone they come up with their own theory and because they’re not confident they act like questioning science is not allowed…yet questioning science is natural and it’s largely just insecurities that make for poor word choice).
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
No Mososaur? The largest ever found was 65 feet! Think about that... A 65 foot Shark hunter. All that 'Jurassic World' stuff is true. About them lying in wait, and laying ambushes. Not only were they deadly, but they were smart too. The King of the Ocean, ever. Anything caught in its jaws, was dead. Even Megalodon.
Mosasaurs were actually no bigger than 14 meters. And no, Megalodon is much heavier and have stronger bite than Mosa it don't stand a chance unless its pack of them.
Humans(today) - Animals, you will be glad to know are extinct Animals ( in future) - Humans, you will be glad to know are extinct We are the biggest troublemaker on the Earth
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!
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.
really enjoyed this video and the way it presented such intriguing information about extinct animals. however, i can’t help but wonder if it’s a bit misleading to say we should be glad they’re gone. i mean, every species plays a role in its ecosystem, and their extinction might have consequences we’re not fully aware of. what do you all think?
WRONG. The Megalodon went extinct before the Ice Age due to climate change; the Earth became colder and Megalodon was cold blooded so it froze. The reason why you said that is because 95% of the oceans is unexplored.
@@birdieW-79 Your reasoning doesn't make sense that "Megalodon was cold blooded so it froze". There are a lot of cold blooded animals that survived the multiple ice ages, crocodiles have been around for 240 million years, since before the dinosaurs, they've been through mass extinctions yet they're still around. There are many types of sharks that are still alive that have been around since or before Megalodon evolved and they're all cold blooded and they didn't "freeze"!! It is believed that the rise of whales, particularly predator whales such as killer and sperm whales made it more difficult for Megalodon to compete for food.
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.
i mean, deinosuchus is also substantialy bigger than sarcosuchus too. and to the biggest specimens, the skull of deinosuchus were around the size of the sarcosuchus skull
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.
i really enjoyed the insights in this video, it was informative and well-made. but honestly, i can't help but feel a bit conflicted about celebrating their extinction. sure, some of these animals were dangerous, but every creature has its role in the ecosystem. sometimes it feels like we're just erasing parts of nature instead of finding ways to coexist. what do you all think?
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.
The last massive extinction level event happened around 11,000 years ago when a comet hit Greenland ... well, unless if you count the extinction level event we're living through right now.
12,800 years ago it looks like we had comet fragment impacts across the ice sheets, one of which hit Greenland. Looks like the fragments were about one mile in diameter. The melting from the 40,000 mph impacts shut down the gulf stream and perhaps the Japanese current and caused the Younger Dryas. But an even greater cataclysm happened 11,600 years ago and appears to be a solar outburst or mini nova. That was probably the advanced civilization killer. And they might be cyclic - around 12,000 years per. Seems a water world planet with a molten core is good for incubating life but not so good for long term prospects.
If you want to read the Gospel then I will put something like that in my replies, but if you read that then you should still read the complete Gospel. I put this because in Acts 1:8 it says, “You will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth” so I put this to do what The Lord says. If you read it then like the comment so that more people can see it, and more people have at least one opportunity, because accepting Jesus Christ as our Lord and Savior is the most important decision that you will ever make.
Jesus was born. He did at least one thing we couldn’t do (without Him) as a child. He grew up, got disciples, then did some more stuff we couldn’t do (without Him). He eventually got betrayed by one of His disciples and He knew that He was gonna be betrayed, and then He got captured, and died for our sins on the cross. He came from Heaven to earth knowing He was gonna die. He did it knowing it was for our sins though, doing it because He loves us. Then He died on the cross for our sins but not so we could keep sinning but so we could stop and be forgiven. He rose from that grave on the third day, defeating death and someday He’s gonna come back and defeat the devil. Romans 9:10 “If you declare with your mouth ’Jesus is Lord’ and believe with your heart that God raised Him from the dead, you will be saved.” Ephesians 2:8 “For it is by grace you have been saved, through faith and this is not from yourselves, it is the gift of God.” 1 Timothy 2:5-7 “For there is one mediator between God and men, the man Jesus Christ; who gave Himself a ransom for all, to be testified in due time. Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity.” 2 Corinthians 4:18 “So we fix our eyes not on what is seen, but what is unseen since what is seen is temporary, but what is unseen is eternal.”
Pelagornis Sandersi lived near seas and ocean and was the largest bird in terms of wingspan reaching 7.3m while argentavis magnificens the largest species of argentavis had a wingspan reaching 5.09m -6.5m.
I think the worst creature you could have ever come across would be a warm blooded giant of the past. Being a cold blooded animals had its advantages. The animal didn't have to regulate their body temperature This meant less nourishment needed and that was a plus in tines when food was scarce. But being cold blooded also limited the developement of the animals brain. I am not calling them inept.Far from it what I mean is these animals have a small set of needs.Such as food, shelter and the occasional companion for mating. As long as those primitive needs are met you have a good chance of surviving an accidental encounter. Now if you came across a warm blooded animal your chance of getting away alive let alone unscathed are in serious doubt. Why! You may ask. Well most warm blooded animals have a higher amount of intelligence than the cold blooded ones. The warmth enabled the brain to grow giving warm blooded animals more options then the basic needs of survival. It gave the animal emotions. If you have a 500 pound black bear angry its going to lash out That's the same years ago if you startled a smiladon its going to do the same thing. Just think of this a TEN foot tall ape like animal with a 6 foot reach and two -three inch teeth.You just happen to come into it's nesting area with his females and infants. You got the short end of the stick To put bluntly.You are screwed!! This animal is going to rip you are apart. Now if you came across a giant crocodile and he already feasted on one of your friends and isn't in the mood for a crying human( that's you or me crying like a baby) You might have a chance
Don’t really remember exactly why the animals were bigger but I think it was because of the oxygen in the past.

Why is it even in this list? it's a top choice for animals you'd wish were still around.
I heard they had muscular NECKS so they used their teeth and literally daggers constantly stabbing up and down
Smilodon had a powerful neck instead of a deadly bite. It would lift its head, open its mouth, and drive its stabbing fangs into its prey.
I could be wrong but Lynx and Bobcats chase and catch rabbits all the time. They could probably turn on a dime, short tail or not.

Some that I caught are 10,000 B.C.,Rampage,Clash Of The Titans(2010), Hercules, Jurassic World,King Kong(2005)and Walking With Prehistoric Beasts(BBC series,I believe)...hope this helped
@@jodyjonas5263 Thank you Jody.

Watch the left hand corner when the scenes pop up, they credit the movies in that corner!
great video, really informative and well put together! it's fascinating to learn about these extinct animals, but part of me wonders if we should focus more on conserving endangered species that are still around rather than just highlighting what's already gone. what do you all think?
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 oxygen thing only aply to arthropods, because they have a diferent breathing system, the giant vertebrate animals usually have to do with, the amount of food available to them, some times the temperature of the ecosystem they're living in and also some adaptation such as the air sacks in dinosaurs, to make their bodies lighter and not die from overheating.
*and with reptiles they never stop growing so long age and an abundance of prey would result in some really big lizards*
Something definitely did happen to the mammals, because many mammals from the past were much larger than mammals today. Check out a baluchitherium, an ancient hornless rhinoceros. It was as high at the shoulder as the head of a giraffe is today. The only case I know of where the modern mammals are bigger are the seagoing mammals (like blue whales). The huge, ancient mammals went extinct for some reason. It's hard to ambush prey if you're huge.
How about my favorite: the Gorgonapsid. A formidable protomammal from before the Permian/Triassic extinction event.

Fun fact: Gorgonapsid is closely related to humans

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.
cool
He also said our closest ancestor from this vid was living around a thousand years ago, lol. That's essentially modern history.
Yeah, these are TH-cam's equivalent of sketchy media. Potentially amusing, and contaminated with bullshit.

awesome video
3:02 It went extinct around 100,000 years ago. This channel is really sketchy, getting all these facts wrong.
2:17 if that thing still alive today we can seeing rumbling and 80% population on earth are vanished
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.
what an interesting video! i really enjoyed how you showcased these animals and their unique traits. but honestly, i can't help but wonder if we should be more focused on the species that are currently endangered rather than those that are already extinct. isn't it a little strange to celebrate their demise when there are still so many struggling to survive today?
Hallucigenia forti look like the the creature that turn Ymir into the first founding titan, I think so
You might turn into a titan if it touched you
I believe that was the inspiration for that titan giver. I don't exactly know.
Attack on titan Reference
Your seeing things!
This was so fascinating!!! I love seeing videos like this!!!! 🤩🤩🤩
Even though there are super deadly creatures I would probably be okay if they were still alive
this kind of footage always gives the impression a deadly creature was lurking in every nook or cranny.
most predators are sparse and wide distributed and how many people living in the area where cougars excist see them on a daily basis? Hardly anyone.
I would never love to see them😱😱😱
I like snakes oh thought I don't want to have a pet titanoboa
If T Rex and Sabor Tooth Tiger and magolodon were still alive i would never go on a Safari and never go in ocean and never go in jungles
@@smonkeyfunkid5980 If they existed, I'd love to have a pet titanoboa, except, it would probably eat me on a dime, and also cost a fortune to sustain lol.
really enjoyed this video, it was super informative and nicely put together. but honestly, i can't help but think that the extinction of these animals, while sad, might have opened up opportunities for other species to thrive. sometimes nature needs a little reset, right? what do you think?
what an intriguing video! i really appreciate the effort that went into showcasing these extinct animals. however, i can't help but wonder if sometimes we focus too much on the fear these creatures inspired rather than acknowledging the role they played in our ecosystem. it's like, while it's good to learn from the past, maybe we should also be careful not to glorify their dangers when discussing their extinction. just a thought!
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
We can appreciate them and still be glad that they are extinct. Mammals were no bigger than an opossum when Dinosaurs roamed the planet as an example. You had a lot of Mammals that have tiny descendants compared to what we had then. Sloths as big as 20ft, etc. Considering how dominant Black Bears, Grizzly Bears, and Polar Bears are today, I'm glad that Cave Bears went extinct as they were far larger and more scary. I'm sorry, but Dinosaurs sharing a planet with Humans would mean that we were screwed. It would be far worse than what you saw in Jurassic Park.
@@Deadsea_1993 cave bears were less agressive and had a more herbivore sided diet.
non avian dinos livig with us does not mean we are screwed, just some species woukd screw us, like carnivore theropods, while dinos like ornithomimids and dwarf sauropods could live with us
Snakes and spiders are the worst creatures on the planet. What blows my mind is that some people think eating meat is wrong but do not complain about animals eating other animals.
You’d only be sad until one of them were feasting on your lifeless carcass. Me? I’d be giggling while watching from a safe distance away.
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!
"Have you ever thought about worms with legs?"
No....no i don't
great video! i really appreciate the effort you put into showcasing these extinct animals. however, i can't help but wonder if we’re too quick to celebrate their extinction without considering the ecological roles they may have played. what do you think?
really enjoyed this video! it's fascinating to learn about these extinct animals and the impact they've had on ecosystems. but honestly, it kinda makes me wonder if these animals were really as deadly as the title suggests. i mean, some of them might have just been misunderstood or became extinct due to human actions. what do you all think?
I like how you pronounce all these extinct names that are hard to pronounce so easly
@Liked Monkey only for arthropods
They would all be in danger by us if they were still alive
This was a awesome video. I'm so happy these animals aren't alive anymore. ;)
Well even if they were alive they wouldn’t ruin everything
I wish to see all of them in real life
except the worm one
@@orangutan4919 I would be million times more scared of the ocean or water if those damn things were alive
@@hamburgerhamburger4491 but would they hurt you if they did not go to the water?, even maybe there is a titanic sized creature in the ocean because we did not discover all parts of the ocean
@@orangutan4919 it doesn’t matter, how would you like it if you were walking and all the sudden a giant centipede wants to eat you
This was very enlightening. Appreciate it!
i really enjoyed this video! it’s fascinating to learn about animals that are no longer with us, but i can't help but wonder if some of them could’ve actually played a role in today’s ecosystems. it feels a bit sad that we’ll never know how they might’ve adapted to our changing world. what do you all think?
I'm so glad you enjoyed the video! It's fascinating yet bittersweet to think about how extinct animals might have influenced today's ecosystems. Their adaptations could have been incredible, but maybe their absence also shaped the world we know today. What are your thoughts on the balance between nature's loss and evolution?
I want many of them back🌿
Same especially the ziber tooth tiger 🐯🐅 and husks eagle 🦅
The saber tooth tiger would make us extinct
2:20 when you get too addicted to anime and mistaken this creature for the one who made the first founding titan
Can you stop watching aot and live
Lmao
Animals were many massive in size because there were a lot more oxidant in the atmosphere
Cool fact

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.
What are the movie credits? I’d like to see some of them. Esp the one with the mammoths.
The movie is called 10000bc
@@freetard1759 thanks! ....and I found it on YT for free :)
From all of this species only deinosuchus argentavis titanoboa and phourassuhus were scary. But really good video!
Scheich, Papo and Modjo have GOT to make toys of these!!
as to your initial comment at the begininning of this video, We SHOULD ONLY work hard to ensure WE AS HUMANS do not cause the extinction of an animal/plant species. If however it is a NATURALLY occurring extinctinction event, then SIMPLY let Nature take it's course.
I have a question about Anomalocaris….something about those toothed tentacles has never looked right to me. I like the design but I’m curious how palentognists know for certain that it was hunting like it is in the clip? Those tentacles I always thought looked more like they could be being used to dig into the ocean floor to find hidden animals(it’s that scene out of walking with monsters where it’s eating a trilobite that makes me question how practical that using them for that is). I don’t know I’m not an expert and I’m probably looking at it from the advantage of a few millions years removed.
I think they have found numerous tribute remains with bite marks matching the mouth parts of anomalocaris. But over 400 million years the best the best of us can do is guess.
I agree with both of you…they probably did both…attacked and searched in my opinion…so true that all we can do is guess though
paeontologists never know anything "for sure". That's not how science works in general. Science only knows the truth approximately and can only talk approach it as closely as possible, but never 100%. And true science NEVER claims to do that. only people who produce youtube videos claim to present "truths".
@@fiedelmina You are right and I think I misspoke when I put the comment up originally because I was insecure and thought I sounded stupid(I think it happens to everyone they come up with their own theory and because they’re not confident they act like questioning science is not allowed…yet questioning science is natural and it’s largely just insecurities that make for poor word choice).
i don't believe that fossils are so old, nothing from a million years ago should be able to exist
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
No Mososaur? The largest ever found was 65 feet! Think about that... A 65 foot Shark hunter.
All that 'Jurassic World' stuff is true. About them lying in wait, and laying ambushes. Not only were they deadly, but they were smart too.
The King of the Ocean, ever. Anything caught in its jaws, was dead. Even Megalodon.
Mosasaurs were actually no bigger than 14 meters.
And no, Megalodon is much heavier and have stronger bite than Mosa it don't stand a chance unless its pack of them.
@@januszpolak254 Tylosaurus is 14 m Mosasaurus is 17 m
Humans(today) - Animals, you will be glad to know are extinct

whats the shot from the sabertooth part from? what movie is it?
4 ever green : look at this prehistoric monster
Me who plays ark: I'm 3000 lightyears ahead of you
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!
What a collection of crap. Haphazardly and unspecified info, collected of other (better) channels.
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.
Don’t worry. Most Americans can’t gauge 6 ft either.
Average height of a person is 6 feet.
every three feet is a yard, and a yard is 0.9144 of a meter. So almost two meters.
really enjoyed this video and the way it presented such intriguing information about extinct animals. however, i can’t help but wonder if it’s a bit misleading to say we should be glad they’re gone. i mean, every species plays a role in its ecosystem, and their extinction might have consequences we’re not fully aware of. what do you all think?
Native Americans killed off North America's Megafauna that wasn't wiped out by the ice age. Whereas Africa still has it's Megafauna.
Fun fact: *megalodon is still here in 95% of the ocean*
Relax. 😭😭😭
no
WRONG. The Megalodon went extinct before the Ice Age due to climate change; the Earth became colder and Megalodon was cold blooded so it froze. The reason why you said that is because 95% of the oceans is unexplored.
@@birdieW-79 Your reasoning doesn't make sense that "Megalodon was cold blooded so it froze". There are a lot of cold blooded animals that survived the multiple ice ages, crocodiles have been around for 240 million years, since before the dinosaurs, they've been through mass extinctions yet they're still around.
There are many types of sharks that are still alive that have been around since or before Megalodon evolved and they're all cold blooded and they didn't "freeze"!!
It is believed that the rise of whales, particularly predator whales such as killer and sperm whales made it more difficult for Megalodon to compete for food.
@@1wor1d Mako sharks and great white are warm blooded.
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.
i mean, deinosuchus is also substantialy bigger than sarcosuchus too.
and to the biggest specimens, the skull of deinosuchus were around the size of the sarcosuchus skull
Deinosuchus is more related to alligators than crocodiles.
All of those monsters just devovled into what we see today
I'm absolutely thalasamophobic 🙂👍
They are so strong deadly and powerful we would not stand a chance we are lucky they are dead
I can appreciate the past, but it's the future that sometimes gives me the willies.
props to the camera man for recording this much extinct animals
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.
For some reason, they aren't the stars of bad movies.
My favorite animals is megalodon shark
i really enjoyed the insights in this video, it was informative and well-made. but honestly, i can't help but feel a bit conflicted about celebrating their extinction. sure, some of these animals were dangerous, but every creature has its role in the ecosystem. sometimes it feels like we're just erasing parts of nature instead of finding ways to coexist. what do you all think?
Scientists- We don’t exactly know when the last megalodon went extinct
Me- Then how do you know it’s actually extinct
Every person with a brain- Because they literally could not survive today due to lack of food and other factors.
It makes me mad for the fact people say sea creatures are instinct but they don’t know the whole ocean
Imagine if the "Terror Bird" could mimic the Voices of their Preys before they died..😱
Also fun fact: The KELENKEN is terror bird , the narrator is spreading fake information that is clearly wrong
It is what gamers would call a Chocobo. Also there are also Native Indian statues of Indians riding triceratops. And they are not very old.

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'm not an expert but I'm pretty sure it'd be the same as having a pet tiger. Which I don't recommend you or anyone getting.
The last massive extinction level event happened around 11,000 years ago when a comet hit Greenland ... well, unless if you count the extinction level event we're living through right now.
e
12,800 years ago it looks like we had comet fragment impacts across the ice sheets, one of which hit Greenland. Looks like the fragments were about one mile in diameter. The melting from the 40,000 mph impacts shut down the gulf stream and perhaps the Japanese current and caused the Younger Dryas. But an even greater cataclysm happened 11,600 years ago and appears to be a solar outburst or mini nova. That was probably the advanced civilization killer. And they might be cyclic - around 12,000 years per.
Seems a water world planet with a molten core is good for incubating life but not so good for long term prospects.
Which one’s the most massive
Love your video
i LOVE your videos
I think you meant “Sabertooth” as the smilodon because smilodon I don’t think exist
I believe he neglected to give the actual size of the titanokorys gaines. FWIW, it's 1.6 feet (according to Google).
Early humans were also stronger and fiercer
Fiercer than GenZ? I doubt it...
If you want to read the Gospel then I will put something like that in my replies, but if you read that then you should still read the complete Gospel. I put this because in Acts 1:8 it says, “You will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth” so I put this to do what The Lord says. If you read it then like the comment so that more people can see it, and more people have at least one opportunity, because accepting Jesus Christ as our Lord and Savior is the most important decision that you will ever make.
Jesus was born. He did at least one thing we couldn’t do (without Him) as a child. He grew up, got disciples, then did some more stuff we couldn’t do (without Him). He eventually got betrayed by one of His disciples and He knew that He was gonna be betrayed, and then He got captured, and died for our sins on the cross. He came from Heaven to earth knowing He was gonna die. He did it knowing it was for our sins though, doing it because He loves us. Then He died on the cross for our sins but not so we could keep sinning but so we could stop and be forgiven. He rose from that grave on the third day, defeating death and someday He’s gonna come back and defeat the devil. Romans 9:10 “If you declare with your mouth ’Jesus is Lord’ and believe with your heart that God raised Him from the dead, you will be saved.” Ephesians 2:8 “For it is by grace you have been saved, through faith and this is not from yourselves, it is the gift of God.” 1 Timothy 2:5-7 “For there is one mediator between God and men, the man Jesus Christ; who gave Himself a ransom for all, to be testified in due time. Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity.” 2 Corinthians 4:18 “So we fix our eyes not on what is seen, but what is unseen since what is seen is temporary, but what is unseen is eternal.”

There are tons of modern day animals far more dangerous then any prehistoric animal
Maybe.. big maybe just as* but definitely not far more. Are you dumb or just blind?
I just find it fascinating about what was around millions of years ago 😊
I think the worst creature you could have ever come across would be a warm blooded giant of the past. Being a cold blooded animals had its advantages. The animal didn't have to regulate their body temperature This meant less nourishment needed and that was a plus in tines when food was scarce. But being cold blooded also limited the developement of the animals brain. I am not calling them inept.Far from it what I mean is these animals have a small set of needs.Such as food, shelter and the occasional companion for mating. As long as those primitive needs are met you have a good chance of surviving an accidental encounter. Now if you came across a warm blooded animal your chance of getting away alive let alone unscathed are in serious doubt.
Why! You may ask. Well most warm blooded animals have a higher amount of intelligence than the cold blooded ones. The warmth enabled the brain to grow giving warm blooded animals more options then the basic needs of survival. It gave the animal emotions. If you have a 500 pound black bear angry its going to lash out That's the same years ago if you startled a smiladon its going to do the same thing.
Just think of this a TEN foot tall ape like animal with a 6 foot reach and two -three inch teeth.You just happen to come into it's nesting area with his females and infants. You got the short end of the stick To put bluntly.You are screwed!! This animal is going to rip you are apart. Now if you came across a giant crocodile and he already feasted on one of your friends and isn't in the mood for
a crying human( that's you or me crying like a baby) You might have a chance
