Whoops! At 25:44 forgot to put in the citation to Hone, et al. (2015) "The wingtips of the pterosaurs: Anatomy, aeronautical function and ecological implications."
A helpful individual found Bennett's 1994 paper on the Biodiversity Heritage Library--see the link in the sources doc!
No worries
Excuse moi friend, but where do you get your papers from?
I have been trying to find an english description of that dinsauriform silesaurus.
The “drop from cliff” misconception got me thinking how fun it’d be if YDAW did a “Disney’s Fantasia” ep
If we ever get into doing dino-related media, it'd likely be something we look at for fun!
I thought you were going to say”is would jump of cliffs and fly
@@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 ❤
@@YourDinosaursAreWronghey are ptrerosaurs still lagerpetids?
@@beneficent2557 Probably/Maybe
that water launch animation at 22:10 was so useful in understanding what was going on. Also it looked super cool.
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.
Wait, are actinofibtils surface features?
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
OKAY!
Sorry to be that guy but Pteranodon was a pterosaur not a dinosaur. They're both avemetatarsalians so...maybe pass?
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.
@@littlerave86 They only are as long as science is constantly fact checked.
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.
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.
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"
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.
I think most birds will at least attempt a similar pose for a variety of reasons
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.
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!
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 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.
Brazilian here! Just a heads-up, Anhanguera is pronounced "An-YAN-gwera"! An N and H together in Portuguese make a similar sound to the ñ in Spanish!
Not the fancy 'n' bro.
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 UA-cam’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.
You all knocked it out of the park with this one. Very detailed!
That's sweet of you, thank you!
Knocked it out of the jurassic park if you will
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.
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 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!
Awesome update for the episode! Can't wait for the teased synapisode!
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.
I genuinely sighed in relief after seeing that bit! XD Glad I got it right
@@DeadSoundit was a happy accident!
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.
I find an indescribable joy in your videos, thank you
Wow, thank you!
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!!
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.
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.
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!
Came here after seeing the Short comparing to bat wings, super interesting stuff! Thanks so much for sharing!
Pteranodon was my favorite classic episode, amazing improvements have been made across the board.❤
Aww, thanks!
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!
Glad it was helpful!
always appreciating the care that goes into producing these, and of my favorite group
Good episode, I'm really pumped for the pycnofiber synapisode!
I really enjoy these revisitations!
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!
Oh wow I just opened UA-cam not realizing this was just starting
This video cleared up a lot of questions i had about how pterosaurs flew. Namely the fiberous structures in the membrane and distributed muscle mass.
Yay! Happy to be of help. :)
another absolute banger. can't wait for the synapisode!
Fantastic! Love the reuploads and corrections
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...
Waited so long for this video, thank you 👌
Hope you enjoyed it!
comment for the algorithm! these videos are great. I remember watching some of these way back, happy to see them being given updates in this way
“ … so I’m not going to elaborate here.”
You. Tease. Us.
No idea what you could mean. **whistles**
I love your newer episodes and I can't wait to see another full new episode. Pterosaurs are my favorite!
I always thought pincofibers was more fun to say anyway.
pink-o-fibres
Pterosaurs are so fascinating, thanks for this video.
omg the paddle wings lool
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 like that this series is effectively Your "Your Dinosaurs Are Wrong" Are Wrong
love y’all’s content 👍
I already know this is going to be fire
Awesome video as always
Thanks!
babe wake up ydaw posted another banger UA-cam video
The water launch question has been DRIVING ME CRAZY!!! THANK YOU!
And then you even brought up the scansoryopterid issue!
Amazing content, thank you guys
Our pleasure!
I know it’s not a dinosaur, but I’d love to see a video on Smilodon. There’s not many videos on UA-cam that actually go into depth on it, so I’d love to see YDAW’s take on it.
Love it. Thank you!
You are so welcome!
Loved it
Very interesting, thanks for the remake
Our pleasure!
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.
Another great video guys 🦖🦕🦖🦕
Thanks so much!
Immediate thumbs up for TARDIS sound.
I'd love to see you do an episode looking at the dinosaurs in Ark Survival
Bats use all four limbs to get around when on the ground, usually pretty bad at taking off from the ground tho
awesome video : )
WHY HAVENT I SEEN THIS I HAVE NOTIFICATIONS ON
0:27 Lol didn't expect a doctor who reference XD
So you briefly got into the weeds in terms of wing shapes, but my question is did pterosaurs have as diverse of wing shapes as birds do now? Like, short/rounded wings for high agility, long & pointed for high speed, and large & broad for soaring. Is there evidence of these different flight styles in the morphology of pterosaur fossils?
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!
Y'know, that's a pretty good idea!
@@YourDinosaursAreWrong It would be great!!!
I agree about the often less than helpful pedantry around it but as a science communicator in a museum and lover of pterosaurs my most common brushes with “pterosaurs are not actually dinosaurs” is to combat a common view I come across of Pterodactyl just being one kind of dino and I find explaining that pterosaurs aren’t actually dinosaurs and are in fact their own group with an almost equally varied diversity within them full of amazing cool characters other than just pterodactyl! :)
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: ua-cam.com/video/IH5IGhi2Pu8/v-deo.html
31:37 Rhamphorhynchus mention!!!
a mummified pterosaur would probably be the greatest discovery ever (in my opinion)
Do we have any idea if late Cretaceous pterosaurs were overall better flyers than bats and birds?
Oh sorry, was I meant to work this morning? can't. YT just told me there was a new YDAW upload
Pteranodon reupload nice
How is my comment being posted before the video was released?!? Am I a time traveller? 😧
10:21 “pterible” if you will…
Booooooooo.
Gonna fly now~
could you do an episode on Deinocheirus?
Ludodactylus' name is really cute! Because it looked like the stereotypical Pterosaur toy it was given that name it's funny! Life imitating art I guess.....
I like the Tardis sound
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.
That first toy is a Rodan from Japanese Godzilla toy, change my mind
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
Oooh boy
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?
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!
That's obviously Rodan🐦🔥🐸
This guy sound exactly like the williaso guy !!!
🦖🦕😊👍
Reconstructing the body of Spinosaurus
I never got on the convex wing bandwagon, feel validated now
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 like to think pterosaurs were more like birds than dinosaurs
@@scottthesmartape9151 Birds are dinosaurs
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.
@@user-H_m I think they mean, they are more behaviorally, and visually similar to extant birds than to non-avian dinosaurs
@@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.
"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.
Don't get me started how inaccurate the Flintstone's car was....
Why this episode oddly comedic lol?
A theory put forth on another vid supports idea pterosaur? launched much likes (fores: vampire bats) that 'vault into flight using their wings when done feeding from mammals.
It will never not be funny to me how much hotter Steve got lol
