What I learned from this: bats have the potential to be giraffe-sized flying mammals.

[@noahmccann4438]

I was looking for a comment about this. I was wondering what holds them back? It would seem ideal for them to get larger, because heat loss is a big problem for smaller mammals. Well that led me to do some quick searching, and they lack the hollow bones of birds - they solved the weight problem by slimming their bones down, making them lighter but also more fragile. So that might be a limiting factor. I seem to recall that bats and birds approach waste management differently, with birds having low water content in their waste to reduce weight, while bats are more similar to other mammals - with vampire bats sometimes peeing while eating to keep their weight down (and also to maximize the nutrition they get). Some capabilities of bats might also be wasted by getting larger - perhaps echolocation isn’t useful if your prey is above a certain size. All that said - it would be easier for a bat to solve those problems via evolution than for a bird to develop a similar launching method, so perhaps with the right environmental factors driving them we would have giraffe sized bats one day. What a scary (but awesome) thought!

[@Rupcoris]

@@noahmccann4438 it's because of the same reason mamals were small and weak during the dinosaur era. birds are dinosaurs so it's kinda like bats are stuck in that same position. also birds occupy the ecological niches of "big" flying things and they're very good at it, so as long as birds keep that position bats have no chance of getting bigger. of course the're must be a lot other factors involved but those are the ones i could think of

[@nedaraid3372]

All interesting points in the comments but the more probable explanation is because mammals have heavier bones including bats. The hollow bones are what let dinosaurs and pterosaurs get to their giant size.

[@Rupcoris]

Richmond Espinosa yeah, but they’re hunted by an even bigger bird, the philippine eagle xD

[@drenrin2120]

It's a pretty interesting thought experiment to wonder what bats may look like in 40 million years, but as has been pointed out, they'd have to overcome their bone density problems and wait for a niche to open up that encourages gigantism as an adaptation. That kind of implies another extinction event which means they'd have to also survive that event in order to have a chance of taking over any niches left behind by birds. Given the amazing myriad of ways in which life has diversified on Earth, I don't think it's impossible if all the right things were to happen.

@@ManpasTheBreathingHuman Wrong, please update your understanding of the laws of aviation :) They do not fly like birds, they fly like insects. And their wings have the perfect size for that insect flight method. So the question is, why do people still believe, that they violate some laws of aviation, if people try to use methods of birdflight for beings, that do not fly like birds? For starters, bee wings work at about 200 Hz, that are about 200 wingbeats per second. I don´t know any bird using similar wingbeat frequencies (not even the hummingbird uses that much) Google for insect flight, it´s a really interesting topic.

is there any method to measure historic ATMOSPHERE DENSITY?

[@JoseGranny]

I wonder if atmospheric conditions played a part in pterosaurs’ ability to fly, as well.

[@besmart]

So I left that out of the final video, but I asked Dr. Habib about this and here’s what he said: “The overall atmospheric density was probably about the same as it is now. But pterosaurs lived for a big part during a low oxygen environment. Flying in a low oxygen environment should be more difficult, but it affects small things more than big things. So the low oxygen environment may have prompted the evolution of vertebrate fliers, because there were a bunch of handicapped insects basically hanging out that may have been easier to catch. The lower oxygen at the end of the cretaceous may have also promoted very large fliers. Large fliers can flap in bursts, using muscles that don’t need as much oxygen. That’s called an anaerobic muscle, the fast-twitch muscle. If you’re a big flier you can do that much more effectively than a small flier. A small flier has to use aerobic muscle, that is, muscle that is oxygen utilizing when it’s working hard.”

Love the video, qeutzlcoatlus and other azhdarchids are some of my favorite animals. Pterosaurs weren't dinosaurs, but they weren't very far off either.

So honestly including pterosaur toys with dinosaur toys is kind of... almost correct in a way

[@Dragrath1]

Yep the exclusion is more a consequence of where we decided to define what a dinosaur is rather than a lack of a relation. They even shared a number of major anatomical characteristics such as the one way flow respiratory system of archosaurs and one of the more surprising findings being that the early dinofuzz feathers of dinosaurs and the fuzz of pterosaurs were so functionally identical in their detailed microstructures that the trait basically had to have shared a common origin from their last common ancestor and that coupled with finding primitive feathers on ornithischian dinosaurs all seems to suggest they all shared a fuzzy last common ancestor which is kind of amazing. That respiratory system also seems to have led to hollow bones by incorporating their air sacs into their bones as part of the respiratory system not dissimilar to how mammals incorporated their blood production organ into our bones. The thing at lot of people misunderstand about their hollow bones is that thanks to the internal structural scaffolding their bones weren't weak the same light weight bones which helped pterosaurs and birds both develop flight also were one of the major innovations that enabled he sauropods to get gigantic. It is amazing the kind of things there used to be on Earth... If it hadn't been for that cataclysmic asteroid which literally was one of the three largest asteroids to hit the Earth since the Hadean Eon.... Vredefort Impact 2,023 Ma, Sudbury Impact 1849 Ma, Chicxulub Impact 66 Ma There is a reason it is the only asteroid impact directly related to an extinction event the 4th largest known asteroid to hit Earth in the geological record was orders of magnitude smaller/less energetic.

I was really hoping on seeing a discussion on how rounded a pterosaur wing ought to be to prevent drag from overpowering the lift caused by their airfoil.

Basically all flying animals, vertebrates and invertebrates, have developed a fairly rounded wing tip (in the case of bats, the presence of the 4th phalange going through the middle of the patagium causes that membrane to connect at a more obtuse angle and increasing the surface area at the tip. Did you discuss that with the experts?

bats are atuck in eating polem, fruits and insects, they evolve the ecolocation to find moths and other insects in the dark...... they cant go bigger than the brazilian giant bat ... they are in the best ecosystem and they cant grow larger

[@WEE9]

@@darkmistico if we do some mods they could maybe be as big as like pigs maybe

[@erikperhs_]

@@darkmistico I'm pretty sure the Australian "flying fox" is the biggest bat in the world.

[@rauntche]

I don't care if they might eat the kids. I want to see dem giant flying lizards.

Biomechanist! Your guests do always cool and strange jobs that I wish had knew they exists when choosing the University 15 years ago.

[@Banzybanz]

Interesting how despite superficial similarities, the bat, pterosaur and bird wings are all structured differently. Bat have enormously long and thin fingers and the wing forms the webbing between all the fingers, and between the little finger and the legs. The pterosaur wing is similar but it hangs only off the 4th finger. Bird have rather small finger bones and the feathers attach to the ulna, the palm bones and the finger bones.

[@Composite7248]

would it be terrifying to have pterosaurs around? or pterrifying?

[@besmart]

👏👏👏

[@RickMason-yj7pv]

Ptraumatic to be sure

[@stefansauvageonwhat-a-twis1369]

Petrifying, or even petrifying

[@Lena_Dt]

In 2018, a huge pterodactyl was found. They called it Dracula and the wing span was about 12 meters. The bones can be seen in a museum in Germany, very impressive! Probably the largest pterodactyl in the world

[@censusgary]

The “Qu” in “Quetzalcoatlus“ is pronounced like “k,” not like “kw.” It’s based on Spanish orthography.

[@austinshoupe3003]

Aren't all binomial terms pretending to be Latin?

[@rogeriopenna9014]

It looks like it's based on Aztec.

[@isaaclopez63]

It is Aztec, there is a God with a similar name called Quetzalcoatl meaning feathered serpent . But I'm too lazy to go into it's History, it is amazing though, such an amazing God. And btw, your explanation on the pronouncement is not exectly correct 😅 I'm Latin so I know.

[@rogeriopenna9014]

@@isaaclopez63 You are latin? From Lazio, Italy? or are you a LATINO-AMERICANO? (Latin American)

[@rogeriopenna9014]

In portuguese, which is another Iberian language, Q can have both sounds. QU followed by O or A always have a KW sound. QU followed by E or I can have a KW sound if the U has ¨ above it (Ü) or K sound if there is no U. But less than 10 years ago there was a spelling reform that eliminated the Ü, so now you can´t know just reading if it's a K or KW sound. Just like english you now need to decorate the pronounciation of words! Preposterous!

[@AxionSmurf]

This channel is friggin great

[@jonezzzyyy6192]

I'm sure it would be unreal to see one of these creatures fly...

[@kramermariav]

Anhanguera is like a head with wings, lol

[@Bonzothefifth]

I’ve heard that larger pterosaurs like Quetzalcoatlus may have been the only species’ to take advantage of the niche of the high atmosphere where some flying insects can dwell well above birds, feeding like a balleen whale passively ingesting whatever might be in its path. But I’m not sure if that would actually net any net calories since I’m sure having its mouth open must affect the aerodynamics and probably dried it out too quickly to be worth the effort. But it’s a neat thought.

[@forrestgump8717]

I'm more interested about how they get that neck to stay straight instead of how they fly.

[@gormauslander]

Seems unbalanced

[@dantan1249]

It’s probably naturally rigid like a lot of dinosaur tales. Also, when an object flys, there is a lot of lift on the front portion which is probably why they were so front heavy.

[@timmy7201]

12:55 - _And honestly after seeing those bones up close, I can't decide if it would be really cool, or completely terrifying to have pterosaurs around today._ Imagine having to repair your roof, every time one lands on it...

i luv the name of this channel because i feel there is a real stigma to learning and gaining knowledge. In America it's a virtue to be as dumb as possible. Just look at our "president"

[@wholeNwon]

He isn't a dumb as possible but pretty close.

[@EverythingScience]

Real question: How did the giant pterosaurs get a p in it's name

[@b3z3jm3nny]

pter means wing, it’s the same pter as in helico-pter :)

[@newtscamander7713]

Because Greek

[@niklasschmidt3610]

Thank you so much for uploading this video. It is helping me get through the pandemic!

[@fappjack0067]

I thought you're Johny Knoxville for a moment 🤣🤣🤣

[@Gandorhar]

Well the most important thing I learned is that the "P" in Pterosaurs is silent. I always tried to pronounce it with the "P" and it just sounded wrong. Anyway ofc the rest of the video was more intressting than that little fact, great video I loved it!

[@AnaboliKitchen]

Maybe to native English speakers, but we who pronounce p in “pterosaurus” in our languages don't find it weird.

[@shamoy1000]

Huh. All these " experts" finally figured out how to ask an expert in another field. Kind of pitiful it took this long.

[@andrewstahl6916]

Thank you johnny Knoxville for teaching me about Giant Pterosaurs!

[@davidvarga2916]

That was my first thought as well.

[@monkeytron5061]

So the wing alone launches them just in two different ways, jumping and flapping. I didn’t know that! I love that!

[@orhanozkan7358]

I played Voleyball in high school and that slow motion bird takeoff really was fascinating. I am 174cm aorund 5,8 inches and i can see above the net when i jump. What fascinated me was the motion i (and voleyball players) do it is the same with a bird take off. We stretch aour arms backwards, Jump with our legs and kind of do the flapping motion but obviously not to fly but hit the ball. Thats amazİng

Michael Habib? I recognize that paleontologist, he is one of the paleontologists who curated Pterosaurs: Flight in the Age of Dinosaurs, and discovered Quetzalcoatlus fossils. I also swear I remember seeing him appear in one of the videos for Uncovered in Prehistoric Planet 2.
