Quetzalcoatlus | The Largest Animal To Ever Fly In North America

We all know that T. Rex was the king of land during the Late Cretaceous, while Mosasaurus was the king of the oceans. However, there was a third king, who ruled not land nor sea, but the sky, it was the Quetzalcoatlus. It was a giant pterosaur so mighty, that it was named after an Aztec God. It had a wingspan larger than a small plane, was taller than 3 people stacked on top of eachother, and had a taste for baby dinosaurs, making it one ferocious prehistoric beast.

[@ejtattersall156]

@@goldensaurus It depends if they are opportunistic--see something move, eat it--or specialized--see x, y or z species, eat it, ignore all else. Lions ignore baboons. Lions will kill other predators, but will not eat them. Baboons and other predators fall outside of x, y and z. Will they eat them if forced by hunger? Sure, but they are not disposed to doing so. When I was traveling in Africa, I learned that lions almost never attack humans. The exception is almost always a starving male driven into a village out of desperation because he has been driven from a pride. You don't want to put yourself in a position where you will get attacked by a lion, but they will attack for fun or out of fear, but it is rare. Humans fall outside of the x, y, z parameters for lions, so as a general rule, lions do not hunt humans. Bears, however, will attack and eat just about anything. So will crocodiles. Alligators will not. Crocodiles and bears are more broadly opportunistic. We can never know what a prehistoric animal ate, nor can we know what sort of creature they may have been, opportunistic, or specific. Assuming they would eat humans is interesting to think about, and the idea that they would completely ignore us is boring, but either could be the case. I think more often than not, that they would ignore us. Humans tend to put themselves at the center of things, at the center of the solar system, at the center of life. Historically it was believed we were the center of the universe and life. Science has disproven these things, but we still feel like we are very important. Feeling a prehistoric animal would find us important is a bit egoistic, or at least an unscientific assumption

[@znail4675]

This is even the key reason why they could grow so large. Birds are limited by the fact that they need enough breast muscles to fly plus enough leg muscles to get off the ground while Pterosaurs uses the same muscles for both flight, ground movement and getting off the ground. This is also why there is no reason for Pterosaurs to evolve away flight.

I was told a bird of that size could't fly today, because it needed more air pressure for it's size and wing span. So there's a theory that ancient days the air was denser.

[@poogissploogis]

That's an interesting theory. I know that at different times in Earth's history we've had more or less CO2, among other things probably. I'm not sure if that would affect it, but perhaps different atmosphere makeups could have affected the density.

[@AgroAcro]

I heard a different reason. Birds use different muscles to walk, fly, and take off. This means that at all times the u have muscles that are doing nothing and are basically dead weight. Pterosaurs used the same muscles so they didn't have any dead weight, and could therefore get larger.

[@whynottalklikeapirat]

Actually Quetzlcoatlus made a living as a passenger jet for early humanoids who’d offer up the most unpopular relatives or clan members in return for a quick ride down the hunting circuit. Since these people were fiercely competitive, for a long period of time Quetzlcoatlus made a fat living off this, which, however came to an abrupt ending with the invention of the giant deepfryer giving rise to a brief but vigorous period of excessive binge eating parties causing Quetzlcoatlus to regrettably go the way of the Dodo, but with fries. I say brief because this branch of human development had not considered how reliant they had actually become upon the Quetzlcoatlus infracstructure (which still stands out as a major revolution in transportation to traffic theorists, far outreaching the introduction of the horse in North America). Consequently these early hunter/gatherers were, in turn, quickly wiped out by hunger, and the inability to easily get rid of annoying persons within a socially acceptable framework, both of which, it has been hypthesised, ultimately lead to unchecked cannibalism NOT governed by the shortest straw principle (or in fact any other principles). “Aah but humanoids did not exist at the time and certainly not as organised groups of hunter/gatherers” I hear some of you muttering in the back, but there is a simple explanation to this which is that their skeletons were purely made of cartilage (which would have made “The Merchant of Venice” virtually incomprehensible to them, had it been available as light in-flight reading), which means they were all processed and digested during the horrific cannibalistic wind-down, as they effectively consumed all evidence of their own existence. The remains of the last man standing would have been lost to posterity if not for the fact that he ran into this astronomically unlikely amber incident. I was on the dig that unearthed the motherfucker from my back yard and he was caught in the act by the massive golden blob, wearing a Quetzlcoatlus feather hat while munching eagerly on a wiggly human femur. An elaborate hoax some will likely claim, but I ask in return - where is Quetzlcoatlus today? Hmm? At your local convenience store, perchance? Evolved into a Pretzelcoatlus snack? I think not. Further: word is that having critically reviewed the popular “jurassic park” franchise it is now rumoured that Kentucky Fried chicken has been buying up inordinate amounts of vast food grade steel tubs and are conducting dark genetic experimentation in the vaults under a remote company abode under the codename “Kentucky Fried Park”. “Show us the amber blob then”, you’ll say. I can’t. I sold most of it to 40+year-old ladies with red dyed hair, dark green scarves and a penchant for pilates and hobbyist jewelry making. The remaining bits I traded for buckets and buckets of crispy chicken wings over a period of time, and now, like the early humanoids I am ironically left with nothing.

[@Giavani-wq7gb]

In my opinion these creatures are an example of evolutionary adaptation so exquisite as to provide a niche to thrive in. I say this because the Quetzalcoatlus had to be extremely vulnerable to attack by a host of predators. Whatever their environment consisted of had to be relatively safe. Just a superficial examination confirms a rational conclusion that these Pterosaurs did not just browse anywhere. Their frames were light weight and not meant to ward off predators. Their huge size and lightweight frame constitute a specialized creature used to being out of reach for carnivores generally. Though their hollow bones comprised a lightweight body, I don't see them taking wing from a standing position. Again, very vulnerable. It doesn't look right and stretches the rational. Their environs were most likely on grand cliff faces where a simple thrust could send them soaring. The limbs were suited to climbing up and nesting or drying off on the cliff face, not for carelessly alighting upon an open field or anywhere they could be taken easily. Specialization at its summit. The time it took to provide an animal such as this seems to point towards thousands and millions of years in uninterrupted development to achieve this supreme outcome. One of so many.

I cannot imagine a predator that large actually flying. Perhaps for the best.. Terrifying creature regardless

[@arthurwatts1680]

I knew I should have become a paleontologist - not only would it look cool on a business card, you get to make it up as you go along, secure in the knowledge that no-one is going to dig up photos from 30 million years ago.

Imagine what other kinds there were considered 99% of extinct animals we won't find there fossils

[@snagireddy3283]

Even an albatross, which weighs 10 to 16 pounds, requires an elevated platform with wind gusts or a running head start to gain an initial lift. And something as heavy as the Quetzal could not have been able to land and take off at will.

I like this video👍😊🦕🦖

He couldn't fly but he sure could do a good glide. He lived surely in mountain terrain

[@AgroAcro]

They probably could actually fully fly.

Best channel.

Da biggest bird

[@ubergooberumbergumber5155]

Is it bad that I would still want to see one in person like it’d probably kill me faster than I could blink but to think of an animal the size a fighter jet soaring across the sky is terrifyingly mesmerizing to think of Dinosaurs in general are terrifyingly mesmerizing

[@mexicandog5224]

I think hatz is scarier because quetzalquatles was a fish eater and ate only ate small prey so it didn’t need a stalkier build like hatz did and hatz was a apex predator on a island of dwarf Dino’s called hateg island so hatz could deal more damage and strike and fight more aggressively and also it hunted animals the size of us further backing up the fact it was strong and it would be glad to eat us as a meal if its hungry.

How come we do not find their ancient nests?

[@funwithfish1507]

They probably just laid their eggs in small mounds of mud and grass, so I doubt many would fossilise

could you guys imagine if us humans extinguished tigers from gorgonopsids in stuff

@@jesusdiedforyouproofjohn3.16 Quick Question: Why do you always capitalize LORD.

[@jesusdiedforyouproofjohn3.16]

@kade 7263 I enjoy capitalizing “LORD” because I love GOD. GOD is literally the origin of all life. GOD wants you to live FOREVER. No being loves you more than GOD loves you. Revelation 1:8 “I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.” King James Version (KJV)

@@jesusdiedforyouproofjohn3.16 Alright, I see. Have you tried using bold font as well? All you need to do is to type the word you want to say and then put an asterisk in front of and behind it Here's an example: *Orange*

[@jesusdiedforyouproofjohn3.16]

@kade 7263 Did the bold font work? I put two asterisks next to the word orange. *Orange*.

Dinosaurs probably had a blast!

[@hdgehog6]

Size matters, yes, but if I recall...wasn't the atmosphere back then 1.3 to 1.5 bar? Way denser than it is now? Wasn't O2 levels at 28 to 30% and CO2 was three times that what it is today? Just curious......

[@alladeenmdfkr2255]

Idk if it was mentioned in this video but saw a video that shows that they lived in a region where most dinosaurs were small even if they were full grown,micro something or dwarfism it is called,that could be a way how they feed.Hateg Island,nowadays modern Romania

[@alladeenmdfkr2255]

Nvm,this was the Hatzegopteryx not Quetzalcoatlus

[@Rusty_Gold85]

" North America " ?? Can you update the video to say there was no land mass , it was in 2 sections 170-65+ million years ago . Laramidia(west) and Appalachia (East)

[@delta40031]

He forgot to mention a MINOR detail, that the atmosphere was way different back then. The air had a concentration of 35% oxygen and an atmospheric pressure of 3.2 to 4.8 bars. Unlivable for humans.

[@AgroAcro]

Its oxygen was more like 19%, which is less than it nowadays.

[@Clearlight201]

I think it mainly ate tacos. Great video thank you! I saw a lifesize realistic model of one of these, it was awe inspiring!
