Correction to the correction: it turns out Stegosaurus DID lack nails on the third fingers. (Thanks to Matt Dempsey for informing us!)

first reply!1!!!!1!!!11!!!1
just found out a couple weeks ago what stegosaur feet look like, and man ornithischians have weird feet
Matt Dempsey is a god amongst man
@@xemiii why you lookin at there feet?
kinda sus bro
You gotta do T. rex soon you can’t leave T. rex out.
I like how old paleontology is in extremes. Half of them are like "this animal was so large and heavy it must have lived in the water to support its weight" And then some guy runs in "Guys what if the plates on it's back allowed it glide!"
I am surprised no one (that i know) has not merged these two ideas, and thought this plates were literal sails the animal would use similar to sailboats
@@bluecadet8517that's where I thought it was going before he said it was for flying
Nearly ten years later, and I still cringe a little at that "two brains, like a dinosaur" line in PACIFIC RIM, as much as I like the film otherwise.
That's also how they defeated Godzilla in one of those movies, they electrocuted his second brain.
I literally never heard this before today and it's so asinine I just cannot.
Bro, I am baffled that that line made it all the way into the final cut of the film without a SINGLE PERSON catching it
@@ezrataylor2956 it's a movie about giant monsters and robots. maybe their dinosaurs aren't realistic either
@@CoolPorygon maybe the characters don't know much about dinosaurs is that possible lol
Am I the only one that didn't know there was an official term for a baby Stegosaurus? STEGLING??? Thats adorable
Its not an official term, wish it was though :(
I definitely was not expecting the double-plot-twist of stegosaurus ontogeny reverting it BACK to it's old raised back posture from old paleoart as it entered adulthood. This animal truly is the gift that keeps on giving
Kinda reminds me of the back-and-forth on whether or not Coelophysis was a cannibal.
Flying Stegosaurus theory is even more insane than firebreathing Parasaurolophus.
Come on. Firebreathing Parasaurolophus is totally plausable. You are also clearly anti-Stegosaurus, Stegosaurus can fly if it wants to.....
What about that one flying ankylosaurus theory?
Flying Stegosaurus vs Sharknado?
@@Raptorworld22 Don't you mean Hovercraft Ankylosaurus? Where the creature used its club like a propeller to traverse large bodies of water?
@@Crested_Hadrosaur not only could stegosaur fly he breaths fire too;) ...mdar
I did not expect to learn of a flying Stegosaurus reconstruction.
It makes me so unreasonably happy that the thagomizer is actually named after the late Thag Simmons.
I've actually seen Sophie now.
There are aspects of the Natural History Museum that need an update. Much of the Dinosaur gallery is suspended for viewing from an elevated walkway that can no longer be accessed, so it's a little difficult to see some of the animals there now. There's also quite a bit of outdated info there.
Still, the mount for Sophie is very well done, and she was one of the first things we saw as we entered from the second door.
My favorite dino! Evidently when I was 5, the stegosaurus at the Peabody Museum at Yale told me his name was Pincher. My mother made a green stuffed toy version for me-and then another named Spikes when I wore out Pincher.
underrated comment
I now know that a toddler stegosaurus is called a stegling. I am overwhelmed with joy at this knowledge.
It's amazing how big of a difference just a few discoveries can make! Your reconstruction from the original episode doesn't look too bad, but as soon as you showed the new updated reconstruction based on Sophie, it snapped into place and i was kinda like "oh wow, that looks so much more like an animal" lol. There's just something about the improved proportions that makes it like,, the opposite of uncanny.
Legit what I thought when I saw the new model for spinosaurus
"the opposite of uncanny."
Canny
This is definitely the same way I feel after having watched prehistoric planet, like I knew a lot of popular depictions had issues before that, but now seeing depictions of theropods with their teeth sticking out and looking like they've been plucked and starved is extra jarring. I think a lot of the more accurate depictions now just make things Click, and it's hard to even begrudgingly accept anything less. I guess it reminds me a lot of living predators have that kinda harmless :] face when idle, but then when they open their mouth you get the reminder they ARE predators.
Absolutely loving these re-uploads, interesting to see how much our understanding has changed in relatively little time for some of these animals
All of paleontology can be summarized by the simple quote: "Stop making dinosaurs seem dumb" and I won't change my mind
I have been in La Rioja, Spain as part of my biology degree studies and I can confirm there is a bipedal Stegosaurus/Kentrosaurus real life size model just near the fossil tracks. It is hilarious 😂
I love that you're revisiting the old stuff and making corrections. They definitely could have given you a slightly better toy, lol. Hope you'll do more thorough analysis videos like this one. Also, it's weird seeing you without the mustache. 😅
Always good to see a new episode of Your Dinosaurs Are Wrong Are Wrong.
I am autistic and dinosaurs are my special interest, whenever im watching these videos and understanding what hes talking about my mother always says im so smart but no i just really like dinosaurs.
I feel ya man!
This! 100% this!!! /pos
Same lol dinosaurs and prehistoric creatures in general have been my main special interest since I was around 1/12
You are smart! You’re very intelligent about a specific subject.
I dont know if Im autistic but I 100% relate to this.
I for one would love to hear about that study on Theropod intelligence from this year.
Still at awe that in the Sophie video you took the extra step to properly figure the first 3 stegosaurs, namely the partial skull an jaw of Paranthodon and Craterosaurus, and the partial posterior skeleton, forelimbs and cervical vertebae of Dacentrurus (16:30 here)!
You are the best paleo youtuber on the platform by ease, simply because you talk about the proporitions and tiny details that people just don't notice. I am really thankful your channel exists!
Oh, good... the 'gliding stegosaurus' sequence wasn't a fever dream. Which book was that in? Because for some reason I've never been able to find it again.
My day becomes SO much brighter when I have some YDAW to watch, y'all are my favorite dinosaur channel.
Allosaur used call them steakosaurs🐸
I always wanted to pet a Stegosaurus and now that you said they had dog brains (in size) I can imagine how that would go, gives a new visual image to tail wagging.
When I read "Tarzan at the Earth's Core" with the "flying" Stegosaurus I damn near shit myself laughing.
There was an animated Dinosaur video I had growing up that portrayed Stegosaurus moving its plates in a kind of butterfly motion while swiping its tail, in a kind of defensive "I'm big" motion. I think it might even have had eye-markings shown on the plates.
The first toy was an excellent example of Stegosaurus Inaccurous.
I'm so tickled, seeing all of the older episodes updated! Simply because we learn more all the time about these critters, there will always need to be updates. And that's a very good thing!
I now have to go see if I've missed any others besides this one, to this point. 🧐
Thanks, YDAW, for all you do!
❤❤
I can't wait for the Spinosaurus redo
Biannual event
Considering the most recent revision was a mouth that widens when hinging like a pelican, I can't wait for the next one to be
"Oops now it crawls on its belly like a walrus and has a fat reserve for ballast."
love the inclusion of more animations!
Yay, updated vid, corrections and Steve looks *so much* younger! Also the original end credits was cute, and I'm glad to see that it both survived the move to your own channel and was further improved!
No love for Liz yet though? :disappoint:
I love the idea of a stegosaurus gracefully gliding off a cliff
I watched all these originally on Chaotic Good -- it's awesome to see them again, updated for the latest thinking. Thanks. Steve & Liz!
Love this series of Paleo-Accuracy Video's.
I would really love to see an episode on Acrocanthosaurus
I was definitely, totally, very much about to say that Huayangosaurus had a mouth full of teeth, but then you came and told me to shut up. Blast it!
Another excellent video, thanks again!
After watching the Triceratops video (which was probably the first one I ever watched), I thought to myself, “What if there was one for Pachyrhinosaurus? It basically made a cameo in the video, so why not make a video on it?” I know it’s not the best known ceratopsian (despite being fairly popular), but could a video be possible?
Love the updated info 🤩
Great as always!!
I really love these corrections + reuploaded videos, overall hope you had a good day.
Also great content
My first video from this channel, but already subscribed and looking forward to watching more videos
You can really feel the old-school UA-cam in this video.
Thanks for the re-upload.
Very useful, thank you.
Steak appreciates it
I love watching your videos and getting my daily does of dinosaur knowledge and understanding the truth about what these amazing animals actually look like!
I hope you soon do a remastered version on the feather episode and add scale integument as well :)
I love the new information!
I love how painfully awkward those silent pauses are
Very impressive review, thanks!
I work at the Morrison museum, which has the Stegosaurus Holotype. I'm a brag about that.
I would too. That's awesome!
That stegosaurus kite chunky tho🥹
Well, I'm never drawing Stegosaurus as anything other than a cliff-diving glider, now.
LOL when I took my glasses off for a sec (and everything got blurry), that new Stegosaurus model toy kinda looks like some sort of weird Brachiosaur, with the tail being it's head/neck bent down and the models head/neck being a stumpy tail. 🤣😂
Love the update
I just love this
I would love an episode on the Herculano- houzel study of theropods and their numbers of telencephalic neurons
Flying Stegosaurus might just be my favourite new thing.
12:10 mustache is back
I love these informative videos. And you are so cute!
Another thing about the 'two brains' hypothesis. Marsh (and others of the 1880s) would have thought in terms of body parts being "brain" and "not brain". Now we know that not only do some animals have decentralised nervous systems, but loads of animals (even humans) have some of their 'biological decision making' happen in the spinal cord.
You sir have refreshed the recesses of my mind about the the “two brained” theory. I haven’t heard about that since I read about it in 4th grade and im in my 20’s now
It's obvious that stegosaurus flapped its plates like bumblebee wings.
26:00 why not, sounds perfectly valid
About the two brains myth, i distinctly remember that around 8 to 10 years i ago I went to the American Museum of Natural History, and it had a stegosaurus mount, with a plack in front of the display saying it had a second brain
I remember the second brain thing from that Dinosaurs animated/stop motion doco/movie with Fred Savage in it 😅
Just thinking about how people were so sure dinosaurs were slow and stupid that when confused they came up with the idea of a flying stegosaurus before even entertaining the thought that it was not.
Ok. Now i cannot unsee a flying stegosaur. Thank you. Thank you... Thank you.
Now i will cry myself to sleep.
I really love those old intros!
Very NICE
I love this kite! It’s so silly
Second brain in Godzilla vs Mecha Godzilla II and it made a great plot point
So... stegosaurus is going to be a difficult beast to design as a figurine..
11:45 hooo boy, weren't you wrong back then
its always back to the bone wars baby
I'd love to see you analyze the Transformers Dinobots - if not all versions because that would take all day, then at least 2 or 3 versions. I recommend the original (and wrong, especially Grimlock, the T-Rex) G1 and the first reinvention that saved them from the dust bin, the _Fall of Cybertron_ game versions. And I hate Michael Bay's nonsense that ruined everything I loved about them, but might as well do the Bayverse movie ones too.
Wouldn't that make the episode a Your Tranformers Are Wrong episode?
Eh, the Dinobots are overally pretty standard outdated (even for the 80s in some spots) dinosaurs with a few concessions made for transformation purposes. It wouldn't be that different from just critiquing most toys of the time.
You could always send the dinobots in, I might just do that lol
Love the idea of the flying stego.
one of my favorite dinosaurs
As a bonus, Thagomizer is fun to say!
This is great. It's a bit like Your Dinosaurs Are Wrong Was Wrong. Naturally, as more discoveries and better research techniques are made, the information becomes clearer and more refined. The dinosaurs I grew up with are a far cry from what we understand today, and it seems like the science has been improving exponentially.
Would be really cool to see a video about the smartest Dinos and how they hypothesis they functioned.
My guy is looking good, grown into that beard and all since the early vids!
it's head being 3 or 4 feet off the ground seems kinda low. They would have to be bent all down to look like that
The stego kite made me smile. :)
If dinosaurs had voices, they would sound like our host of these vids
My state fossil. The first toy is from the “ scare or impress the kids from the 60’s weird “ dinosaur toy collection. Marx Toys were pretty close to actual compared to those mutants.
You were so angry sounding in the old video! I prefer your current iteration, great work and interesting.
fantastic episode!! with regard to the gliding stegosaurus hypothesis though, i was under the impression that article was satirical in nature/not meant to be taken as a genuine hypothesis?
That kite is hilarious!
These videos remined me of old school Canadian PBS shows that were on late at night lol. Like the old Red Green shows Tom Green always copies and has made fun of maybe I'm wrong either way this is a wholesome dinosaur channel
I wonder if the stegosaurus kite was made in Colorado? They’re fairly popular here since they’re our state fossil.
What I find funny is the fact even tho the group is named after it Stegosaurus as a species is kinda an oddball of the group lol
18:01-18:02: Please tell me baby Stegosaurus are actually called "Steglings".
I'd love a video on one of these biped ornithopods, like Camptosaurus 😃
A classic!
I think they had two rows because it looks better. Also it feels like why would they cram them tightly into one row if two rows worked
First off I want to say that I enjoy all your videos deeply. I greatly like the field of paleontology and all that. Second I want to say that the background music for this episode and many others is a song I’ve wanted to know for a while. I have asked for it before in the comments section but sadly got no response. I saw that you included who wrote the music so I took it upon myself to scour the internet for the song. Two hours later I came up empty handed. So please, I beg of you, is there anywhere I can find this song because I do so adore it.
I will suggest that juvenile stegosaurus may have been facultative bipeds
When do you think the first episode redo will come out
Liking and commenting strictly because of the kite
I feel a distinct lack of love for Bob “Everything in the Morrison is a tripod” Bakker in this video. No discussion, at all, of rearing Stegosaurs? We’re all just going to pretend the Houston Museum of Natural History dinosaur hall doesn’t exist?
