@@YourDinosaursAreWrong i think it would seriously increase your audience if you did. The more "casual" or "fun" videos will draw in a wider audience. I hope you do it someday because i would love those fun videos, too ❤
The "feet bolted on wrong" Pteranodon toy is in fact how bats hold their feet when flying: soles facing down, not up. I'm guessing that's why the toy was designed like that. This in turn is why vampire bats run with their knees pointed backwards, unlike basically all other tetrapods.
When I woke up this morning I didn’t think I’d learn so much about the wing structure of an extinct flying reptile, but I’m not complaining TEACH ME HOW MY DINOSAURS ARE WRONG
I've always thought the standing with wings outstretched pose for toys came from Toho Studios' Radon/Rodan, but maybe it was vice versa. Also, Cormorants do stand like that to sun themselves on good days. Which may be irrelevant but the resemblance is striking.
Iirc part of why Rodan stood like that was the limits of the materials available to the Toho FX teams in the early years of their monster movies. To support the flapping the puppeteer in the suit would have to do with the weight of the rubber wings, they were fairly stiff, and the wide-winged stance became part of his look even in later productions when they had more experience and better materials for newer suits.
If I'm not mistaken the spoon or paddle shaped wing reconstruction seems to have been perpetuated (if not coined by) David Peters on his personal blogs. Those being the top image results for anyone searching pterosaur wing references I assume is the reason the myth is so widely supported online, despite it never being consensus among researchers?
It was also partly perpetuated, at least he said he believes his art contributed to this view, by John Conway, though it seems it was mostly an optical illusion from the various viewing angles he drew them in. I think there was only one old piece where the wing tips were far too elliptical but since then he has drawn them how he believes them to have looked in life, with the front rounded with the back almost completely straight. Darren Naish also doesn't seem to believe it was coined by Peters as it seems it predated Peters' reconstructions that had that roundness.
The problem with the paddle wings is that while they would probably be more efficient for a lot of pterosaurs, it's also silly to assume that A: this one method of flight would be the most efficient for ALL pterosaurs, and B: that all pterosaurs would have the most efficient flight possible. Rhamphorhynchus shows us that it was the case that not all pterosaurs had wings like this, if any did at all.
Oh look, another demonstration of the strength of science: The ability to admit when one is wrong, and strive to improve understanding with new evidence. Always love the YDAW videos, especially these updates on older videos!
I remember a little over 20 years ago seeing a paper online about discovering a pterosaur trackway and I asked if the prints appeared to be bipedal or quadrupedal since there was still debate over that, at least in the most recent book I'd read on the subject at that time. The reply was that they were quadrupedal and I felt like a great mystery had finally be solved. It's amazing how much more has been discovered since then.
Today must be the day of the pterosaur! First I see Ben G Thomas’ azhdarchid video and now this? Excellent! It’s always a good day when two of RUclips’s best paleo-education channels upload!
This channel has single-handedly breathed new life into my old love for dinosaurs and other pre-historic life. Every time you upload I am cast back to being a child, in my room decorated with piles of dinosaur toys, dinosaur books and dinosaur wallpaper - or boring my friends and teachers to death with dinosaur facts. A happier time. I very rarely feel that same inexhaustible passion for learning these days but your videos never fail to reignite that fire in me. Those pteranodon trackways that were mentioned in particular reminded me of getting to see the arthropleura trackways not far from where I grew up in Scotland. I actually felt giddy looking them up. Thank you guys for all that you do, and for having the integrity to re-upload these to correct and update your information. I only wish these videos were available when I was younger and still passionate about paleontology.
31:50 That quote is soo true for Pterosaurs! Surprise, surprise, you can’t really do much biomechanical/aerodynamic studies if you don’t know much about the animal to begin with. Fortunately we have better remains for Pteranodon than for Argentavis, because the latter has closer living relatives with a similar bauplan compared to Pteranodon.
From a windsurfer. The updates to the wings make all sorts of sense. The air sacs are something that have been picked up in race sail construction. They also have been extensively used in wing surf and kiteboarding kite construction. With respect to the fibrils. They’ve existed in windsurfing sails since the mid 80s and they follow a very similar pattern. They’re called battens and you can adjust tension on each batten. They’re perpendicular to the mast near the base/halfway up for lift, more angled toward the tip for maneuvering. Also toward the tip in gusty conditions they depower the top of the sail acting as a suspension.
Awesome. Quality content as always. I can’t wait to see what the Parasaurolophus reupload has to offer. Edit: 22:15 Dead Sound did an excellent job portraying that way we think pterosaurs took off from the water.
Thank you guys so much for this episode! It's great to see this information presented in a way that's useful not only for outsiders who want to learn about pterosaur anatomy, but for clearing up myths unknowingly perpetuated in the paleoart sphere as well.
The water launch sequence at 22:12 makes me think of how the swans at the river near my workplace take off from the water! They're incredibly loud, I can only imagine how much, much more intense a pteranodon would sound! Side note: I really like the style you have for your animation sequences! It reminds me of traditional stop-motion animation using paper cutouts! It's so cool and I really appreciate how much time it takes to get them looking this good!!
I just discovered YDAW, my inner six year old is so bummed! How could I have missed it? Great content! My inner college student that reluctantly decided against paleontology is grateful for the peek into current research, or at least more current than when I was keeping up on it decades ago. Have you seriously thought about doing real, anatomically correct kids toys? Do each one with a little picture book; have you seen Running Press Miniature Editions products? I think they'd be a hit with kids and adults. Looking forward to more YDAW!
Amazing video as always! I've been very interested in pterosaurs after watching Prehistoric Planet, this was very helpful to learn more! Can't wait for the Synapisode on pterosaur and dinosaur integument!
26:11 I tried to explain this to some paleo groups and they wouldn't accept that they had to pull their wings forward rather than have them straight out. Geese do this too, so I was so frustrated that they couldn't get it.
Don't talk to any paleo groups about pterosaurs. For some reason the addition of flight removes all their brain cells in any discussion about a prehistoric animal.
Great update video! Pterosaur research has always fascinated me, they're one of my favorite prehistoric critters, but I've come to terms that everything we know about them will change nearly every year, or at least seems to as something new is always popping up lol!
Yay, more problems in science! On a serious note, this channel ignites my curiosity in a way that few other palaeontology works can. Even though in this video you only discussed one of the possibilities for the arm/wing structure, it's illustrated so intuitively that I suddenly get a better idea of how these animals could have worked. They're odd from a quick glance, but become truly weird when you get closer to their anatomy and lifestyle: the need to be able to lift off of water attests to the fact that they lived in marine environments and probably needed a way to get their mouths closer to fish, rather than hoping fish would jump into their flying mouths. On a side note, pterosaur toys always disappoint because they are fixed to one pose that only represents part of their lifestyle. I saw the larger toy on the table that looked like it was chilling, sleeping, or drowning and wondered if you were going to use that as an example. Now it makes me wonder: in what posture would pterosaurs have slept? Perhaps the arboreal ones would use their claws to hang onto trunks and branches, but it's hard to imagine how the larger ones could have comfortably rested their arms
Excellent video, always love tuning into these. Now I reset my clock and wait for the next video on a pterosaur Surely it will come eventually... surely...
I hope you do some sort of episode covering different paleontology formations. I have found many crinoid, clam, snail, and possibly plant fossils in my river in my backyard here in Kentucky. I really want to know what they are from and what they can be!
Dude, you are so awesome. Thank you for this channel. I’m sending in a toy ASAP! Joined the patreon as well. Please never stop staying up to date on paleontology and giving us such wonderful content.
I know it’s not a dinosaur, but I’d love to see a video on Smilodon. There’s not many videos on RUclips that actually go into depth on it, so I’d love to see YDAW’s take on it.
I would have loved to see them fly in real life. Like how bats are so different to birds in the style they fly, it would be interesting to see how similar or different to other animal groups when it flew.
IMO science communication is just as important as the science itself. That’s why we publish papers when we make discoveries. YDAW’s videos are probably way more widely consumed than the papers they use as sources. And if you consider how well read Steven is because of the research he’s done to write these videos? An honorary doctorate is absolutely in order.
"the current theory is that they're Ornithodirans." No. They ARE Ornithodirans. By definition. The current theory is that Ornithodirans are Avemetatarsalians. If that somehow turned out to be false, which is distinctly unlikely, then Ornithodira would simply expand to include crocodiles and their relatives, or *whatever* and their relatives. If Pterosaurs turned out to be basal Eukaryotes, they would still be Ornithodirans. It's just that this would make all plants, animals, and fungi also Ornithodirans.
Here's a "what if" for you... What if the pterosaur wings weren't membranes at all? What if they were surfaces constructed of bundles of narrow velcro? When readied for flight they would "zip shut" against their corresponding velcro tubes to form a locking stiff surface. When moving about on the ground they would soften, becoming loose "hairy tuffs" bustling about like a rooster's tail. The tension in the wing muscles would create the "signal" to lock the surfaces together. The fibers, individually could be light - even hollow - and to some degree could even move against each other to modify and improve flight characteristics. Dead, these rods or strips would, unless immediately covered, break apart and scatter like loose fur or feathers. So pterodactyl and pterosaurs wings could have been made up of something similar to a bird's feathers, but infinitely more slender 'extentions' of the fuzzy coverage we know they had on their bodies. The weight would be much less and the resulting surface more like stiff, self repairing paper, the leather panels with embedded ligaments to reinforce or stiffen those surfaces during flight.
I think the preserved fossils of closely related pterosaurs says no. This is actually a pretty cool idea for wings though, even if it does not make much sense and is most definitely not true.
@@ShellyTheSeal Other than "flying"... and they likely didnt fly much like birds do... I'm not sure it would be useful to think of them as behaviorally more like birds than bird's actual anscestors. Just from the basic proportions of their anatomy, they are extremely un-birdlike and looking at the movement of birds may actually be a hinderance more than a help in reconstructing or just imagining them. Its not as bad... but almost like watching elephants to try to get an idea of sauropod behavior.
Could you so a re-upload of the Allosaurus video? And include the differences between Allosaurus jimmadseni and Allosaurus fragilis, as well as Allosaurus europaeus? I love your original video and would love to see it on this channel with added information if possible
4:52 One notable development about the bipedal wings-extended pose of the toy is that Prehistoric Planet-which does depict pterosaurs as quadrupedal-nevertheless speculatively shows them adopting this sort of bipedal pose as a display behavior, over and over. See for example: ruclips.net/video/IH5IGhi2Pu8/видео.html
I missed a video???? I went to your channel just now thinking that you didn't publish in so long and I will watch something older and RUclips didn't show me this :(
Wow this guy really knows how to drive home the guilt and shame for my lack of knowledge of plisticene carrion fowl. I need to go hit the books...uhh...what book would I have found this in btw?
This is actually crazy, I was just thinking about how pteranodons specifically would escape the water. Thanks for that. I’d forgotten to google it and I would have forgotten forever. I also need a question answered, When a pterosaur lands would the fingers look like bony wires rather than showing a membrane. For reference of what I mean, perhaps look at the PP quetzalcoatlus and the Quetz of the walking with dinosaurs movie. Idk why prehistoric planet did that, and idk if that’s accurate. And from where I’ve looked in the only one who cares. If you can answer I thank you.
Remember, it is a toy, which is meant to be played with by small children (like under 10 or so). They don't usually care about realism or technical accuracy. They wouldn't see this as a silly thing, instead the wings are out because it flies! Their imagination is better than accurate details.
How delicate would the wing tips be with just the single bones? Did they have any supporting structures? Also my favorite extinct reptile is rhamphorhynchus I would love a video covering
In the year 2525 we will be watching the re-upload of the re-upload of the re-upload of the re-upload of the re-upload until the Platonic Pteranodon is satisfied
Very cool! Have you ever had a look at the dinosaurs in ARK: Survival? There's Survival Evolved and Survival Ascended. I'd love to see your take on how accurate those are~!~! ALSO, could Pteranodon swim and dive do you think?? Like Pelagornis, I assume they could land on the water's surface, but like actual diving, cormorant style?
Y'all need to stop with the giant border on the reuploads. It's pointless and wastes screen space. If you feel the need to mark it as an older video, put a watermark in the corner or something.
Somewhat related, but I love the fact there is an actual pterosaur called Aerodactylus. So we have a pterosaur, named after a Pokemon, that's based off pterosaurs.
That's actually a really captivating image. I can just picture a Pteranodon or Azhdarchid taking off and you just hear this cracking sound like a bow or crossbow firing as it launches into the air. Would be super unsettling.
i dug up some Petosky stones and crionid vertebrae at the river today enjoying the wonderful weather, i wish we had better fossils here in west michigan. i hope you guys are enjoying the season!
It's always been funny to us that we work on YDAW in Michigan, which is bereft of major dinosaur fossils. Petoskey stones are super pretty though, so it's awesome you found some!
There's some clam fossils in the parking lot outside my house. I cannot identify them for an age estimate, but there are 2 or 3 varieties. I might have found some tiny crinoid stems, but I can't be sure.
Thank you for clearing up some of the issues with this episode, that wing membrane shape had been bugging me since the day you released the original episode! The silhouette looked more like a dragonfly wing than a Pter-_anything.!_ Can't wait for more!

This in turn is why vampire bats run with their knees pointed backwards, unlike basically all other tetrapods.
Yeah, their legs are suuuper rotated in their hip sockets. I've heard of them as having "backwards knees", but it's really "backwards entire leg"

Sorry to be that guy but Pteranodon was a pterosaur not a dinosaur. They're both avemetatarsalians so...maybe pass?

I think most birds will at least attempt a similar pose for a variety of reasons
Yep. Your dinosaur is STILL wrong! Thanks for the update. These recap episodes are great!
Thanks for watching!
All those recaps make me fear that my dinosaurs will always be wrong.

If I'm not mistaken the spoon or paddle shaped wing reconstruction seems to have been perpetuated (if not coined by) David Peters on his personal blogs. Those being the top image results for anyone searching pterosaur wing references I assume is the reason the myth is so widely supported online, despite it never being consensus among researchers?
It was also partly perpetuated, at least he said he believes his art contributed to this view, by John Conway, though it seems it was mostly an optical illusion from the various viewing angles he drew them in. I think there was only one old piece where the wing tips were far too elliptical but since then he has drawn them how he believes them to have looked in life, with the front rounded with the back almost completely straight.
Darren Naish also doesn't seem to believe it was coined by Peters as it seems it predated Peters' reconstructions that had that roundness.
Peters’s work looks different to thisthis shape though; the membrane is much narrower, more like a dragonfly than any vertebrate.

Thank you! We're happy that it could help with understanding. :)
It's a concept that I've heard several times before, but I always had trouble conceptualizing it until seeing that animation. It was great.

How is my comment being posted before the video was released?!? Am I a time traveller? 😧
Could you so a re-upload of the Allosaurus video? And include the differences between Allosaurus jimmadseni and Allosaurus fragilis, as well as Allosaurus europaeus? I love your original video and would love to see it on this channel with added information if possible
That reminds me, I really need to commission some Ambopteryx and Yi Qi toys so we can get an episode on them.
I'd love to see you do an episode looking at the dinosaurs in Ark Survival
4:52 One notable development about the bipedal wings-extended pose of the toy is that Prehistoric Planet-which does depict pterosaurs as quadrupedal-nevertheless speculatively shows them adopting this sort of bipedal pose as a display behavior, over and over. See for example: ruclips.net/video/IH5IGhi2Pu8/видео.html
Another great video guys 🦖🦕🦖🦕
Thanks so much!
I like the Tardis sound
This guy sound exactly like the williaso guy !!!
I never got on the convex wing bandwagon, feel validated now
I missed a video???? I went to your channel just now thinking that you didn't publish in so long and I will watch something older and RUclips didn't show me this :(
I beg of you to do Ceratosaurus :D, love ur vids, keep it up
If the Patrons ever vote on it for an episode, sure!
Reconstructing the body of Spinosaurus
You guys should really consider analysis of paleomedia!!
That's obviously Rodan🐦🔥🐸
I'm a little confused, did pteranodon and similar pterosaurs have a rounded wingtip or did it have to be a perfect crescent?
Don't get me started how inaccurate the Flintstone's car was....
Wow this guy really knows how to drive home the guilt and shame for my lack of knowledge of plisticene carrion fowl. I need to go hit the books...uhh...what book would I have found this in btw?
Oooh boy
This is actually crazy, I was just thinking about how pteranodons specifically would escape the water. Thanks for that.
I’d forgotten to google it and I would have forgotten forever.
I also need a question answered,
When a pterosaur lands would the fingers look like bony wires rather than showing a membrane.
For reference of what I mean, perhaps look at the PP quetzalcoatlus and the Quetz of the walking with dinosaurs movie.
Idk why prehistoric planet did that, and idk if that’s accurate. And from where I’ve looked in the only one who cares.
If you can answer I thank you.
Remember, it is a toy, which is meant to be played with by small children (like under 10 or so). They don't usually care about realism or technical accuracy. They wouldn't see this as a silly thing, instead the wings are out because it flies! Their imagination is better than accurate details.
Around 6:00
Completelly different.... so they did it like modern bats when they are on the ground?
Why this episode oddly comedic lol?
omg I didn’t know YALL were the origin of the “rounded wing” pterosaur
How delicate would the wing tips be with just the single bones? Did they have any supporting structures? Also my favorite extinct reptile is rhamphorhynchus I would love a video covering
In the year 2525 we will be watching the re-upload of the re-upload of the re-upload of the re-upload of the re-upload until the Platonic Pteranodon is satisfied
Very cool! Have you ever had a look at the dinosaurs in ARK: Survival? There's Survival Evolved and Survival Ascended. I'd love to see your take on how accurate those are~!~! ALSO, could Pteranodon swim and dive do you think?? Like Pelagornis, I assume they could land on the water's surface, but like actual diving, cormorant style?
I'm pretty sure that Pteranodon should weigh like 20 kg.
can you script these? there's so much dead air where you're coming up with your next sentence
Y'all need to stop with the giant border on the reuploads. It's pointless and wastes screen space. If you feel the need to mark it as an older video, put a watermark in the corner or something.
It's there because the original resolution for the older videos was 720p. Once the older videos transition to 1080p, it will be less of a thing.
Somewhat related, but I love the fact there is an actual pterosaur called Aerodactylus. So we have a pterosaur, named after a Pokemon, that's based off pterosaurs.
All these air pockets make me imagine they takeoff with a thunderous knuckle popping sound.
That would definitely be pretty cool.
That's actually a really captivating image. I can just picture a Pteranodon or Azhdarchid taking off and you just hear this cracking sound like a bow or crossbow firing as it launches into the air. Would be super unsettling.
@@YourDinosaursAreWrong I always think of an inflatable bed mattress for some reason lmao
Brontodactylus would be a great pterosaur name if it hasn't already been used yet.
i dug up some Petosky stones and crionid vertebrae at the river today enjoying the wonderful weather, i wish we had better fossils here in west michigan. i hope you guys are enjoying the season!
It's always been funny to us that we work on YDAW in Michigan, which is bereft of major dinosaur fossils. Petoskey stones are super pretty though, so it's awesome you found some!
I'm glad you're enjoying the weather. It's been very rainy on the east coast
There's some clam fossils in the parking lot outside my house. I cannot identify them for an age estimate, but there are 2 or 3 varieties. I might have found some tiny crinoid stems, but I can't be sure.
@@YourDinosaursAreWrongI feel the same living in Ontario. Canada has a lot of fossils but Ontario barely has anything
@@firytwig *sweats in Southern Albertan*
I wish I could like your videos twice! I have never seen such in-depth and easily accessible science communication before.
Glad you like them!
Thank you for clearing up some of the issues with this episode, that wing membrane shape had been bugging me since the day you released the original episode! The silhouette looked more like a dragonfly wing than a Pter-_anything.!_ Can't wait for more!
I like that this series is effectively Your "Your Dinosaurs Are Wrong" Are Wrong
