"Stegling" That's the cutest term I never knew about

[@rafaelalodio5116]

I know right.

[@namehere4922]

Enzo Agreed

[@barleysixseventwo6665]

Sounds like a Pokemon.

[@ErebusTheDragonn]

Enzo me too

[@BloodClanResurrection]

kinda sounds like a term for a baby dragon

[@markusnavergard2387]

Stegling. i love that word

[@ryaquaza3offical]

I love finds like this tbh “Who are you?” “I’m you, but longer”

[@scientificthings4271]

What a wonderful surprise !

[@ElectroSpino]

A surprise to be sure, but a welcome one

[@HeatherChandlerIHardlyKnowHer]

Scientific Things I doubt people would rage over this discovery, unlike that spinosaurus discovery from 2014.

[@Gew219]

This type of episode correcting the outdated views and filling the blanks according to the newest findings is an amazing idea! Keep it up!

[@seaofseeof]

I keep dinosaurs, psittaciformes. And now I want to call a future one 'Stegling', because that's adorable.

[@peccantis]

Name Stegling's partner Thagomizer :3

[@shitpost9237]

I am one of the few people that are very accepting of dinosaur changes. I love this new Stegosaurus! I always though the old Stegosaurus looked kinda off, dumb like 'how does that thing run, rest or fight without tripping over' kinda dumb. But it looks so much more like an animal now.

[@KhanMann66]

Shitpost If only the general public accept that dinosaurs are animals and not Hollywood monsters.

[@predattak]

@@KhanMann66 pff good luck with that. There are lots of them now in 2020 that think the earth is flat.😂

[@erichstreberg7101]

I dont understand how anyone can get mad about changes to dinosaurs. Updating reconstructions based on new material is so obvious it should go without saying.

[@jackrabot3705]

Baryonyx from Jurassic world fallen kingdom how wrong is it

[@MagentaDystopia]

ironically the one on the jurassic world website was scientifically accurate but for some reason they changed it

[@kyle857]

I didn't even realize that is what it was supposed to be.

[@velocitiegaming7244]

Jack The legassy no

[@riot2136]

Jack The legassy the yellow one with the blue around it’s eye was prey spot on, but they changed it in the movie to probably make it look more vicious

[@yagirljunee]

Yes

[@keef5543]

Ide love to see more little shorts like this. Maybe a series of short 5 ish minute long videos describing paleontological ideas, prehistoric land masses and palaeontologists mentioned in videos so these can be referenced during the main YDAW episodes so those who want a better understanding can get one.

[@timhyatt9185]

I think they'd be especially appropriate for new findings that create large shifts in in how we see the fossils...

[@LordMelusar]

I love this idea, I literally binge watched the entire series when I found it so more episodes in this style going over some random or new bits of info or people? Yes please.

[@zackeryhill3084]

I love how dinosaurs capture our imaginations so profoundly, humanity started to have something of an existential crisis when it found out just how prolific they really were. Discovering that the Earth was once ruled by entirely different creatures created an almost ‘ego death’ that scientists resisted by restoring Dinosaurs uncharitably. Really cool tidbit I never considered despite being an enthusiast for decades; what a wonderful little channel 🦖 🦕 ❤️

[@TheMentorKing]

Synapisode is a funny combination of synapsid and episode, but it doesn't exactly roll off the tongue. Still, I was not expecting something like this and I am pleasantly surprised to have a sort of side-series to Your Dinosaurs Are Wrong; I can't wait for future episodes!

[@StevenBellettini]

I was going for ~ syn-episode, as in connecting-episode, since these will be sort of offshoots or bridges across main episodes. I didn't even consider that it could be a play on 'synapsid.' Also, thanks! Edit: 'Sympisode' might also work but that feels even clunkier.

[@kenwolfe6093]

Steven, this format using the visual aids, while much more labor intensive, is very much easier to follow the points you make. Thank you for making this series of videos. And thank you also Elizabeth.

[@SeaTheStars_93]

It was super cool to have a video with Sophie in! I live fairly near the Natural History Museum in London where she's displayed so I get to see her pretty often! She's definitely one of my favourite exhibits!

[@brycevo]

I now wish we could see more Steglings or other babies.

[@nourrashad7004]

A baby stegosaurus has got to be the cutest thing

[@ChadDidNothingWrong]

cute......until it freaking thagomizes your face ;)

[@Usulcardo]

I absolutely LOVED this short episode. Great job on the animations Steven and on the research too ! It's really important to stay up to date and you found a cool way to do it on this series. I can't wait to see the next one ! :D

[@traxfish]

I actually really appreciate the evolving understandings and depictions of these interesting creatures. Thanks for the vid! I like the sleaker, longer Stegosaurus in this new study.

[@yagirljunee]

You should try baryonyx next Edit: Specifically the one from fallen kingdom

[@andrepirex2209]

I loved the old stego...but... Science is Science and the new one is cool!!!

[@velocitiegaming7244]

thegeekgroup could you do Ouranosaurus next. It was the hadrosaur that lived with Spinosaurus and Charcarodontosaurs(in case I spells Ouranosaurus wrong)

[@HoveringAboveMyself]

Average Gamer300, that was a mistake on the part of Planet Dinosaur. Ouranosaurus was contemporaneous with Suchomimus and Eocarcharia, about 10-15 million years older than Spinosaurus and co.

[@FaceMaul]

I LOVE the ceratopsian head t shirt but I couldn't find a way to change the color. Could you offer them in more colors and would love to see more in that similar style.. Would buy them all! White just isn't a color I like to wear.

[@ChaoticGoodChris]

We'll make sure the right people get your feedback so they can look into providing more colors!

[@apuffin9545]

A baby stegosaurus is called a stegling? That's adorable

[@queenofsiam1183]

I love when research comes to light that challenges our sometimes stubbornly held beliefs on these incredible animals. The more we understand, the better off we will be and the more wonderful these creatures become.

[@timhyatt9185]

I love how you make dino's seem "more real"....more relatable to modern fauna and correct the misinformation that's been fostered for generations now.... Keep up the great work!! I know they're not technicaly dinosaurs, but would love something on the pliosaurs or the mosasaurs....

[@TheCrimsonIdol987]

When I was a kid I loved Stegosaurus. Still one of my favorite dinosaurs, but not my all time favorite. Great video!

[@brycevo]

I'm glad we got a new Episode. Keep up the good work! Thank you.

[@zeinnerp7609]

When you just sculpted a Stegosaurus stenops figure...and corrections come up.

[@tylerbrooks3804]

The bone wars were brought up in episode 12 and I would love NOTHING more than to see a Geek Group review on them, please and thank you! I'm beggggiiiinnnggg

[@TowelGard]

Merch suggestion: a t-shirt with the silhouettes of all the dinosaurs you've done.

[@norncare1]

Stegling is the best thing ever. I can't wait to use that in conversation. This really changes ol' Stegosaurus quite a bit. Definitely going to check out that paper.

[@CryptidHunter13]

This is my absolute favorite series on KZbin. I hope it keeps growing. I wish I could afford to donate.

[@RedRaptor98]

I always wondered how effective the thagomizer was before, because the tail was so high up. This makes much more sense

[@ivanclark2275]

This makes a lot more sense as an animal I think. The long back legs make it seem like it would be both less efficient at walking and not help it defend itself. The tail being ten feet off the ground as previously doesn’t make a lot of sense, because while it does put it at head hight of something like an allosaurus, it would be less versatile. An allosaurus or ceratosaurus would have to be pretty stupid to run right into its tail whether it’s pointed at the head or the body, so all the high off the ground tail would do is limit the tail’s range of motion.

[@VgnRaj]

Animations works very well. Always prefer to watch them while you speak as opposed to watching you simply speak. This is the media we use and I thank you.

[@robinmatz6686]

Great format for a change, charming and entertaining as usual but concise and very grown-up. Nice to bridge the wait for the next full episode

[@SnapDaddy96]

Glad that we have a more complete picture of the animals it was definitely a bit odd that stegosaurus was just so wildly different from it's relatives and I just chocked it up to it dealing with a different type of predators

[@jakoborrazor4059]

You should do this for Ark Survival Evolved. They ended up sacrificing accuracy for good game making, and entertaining gameplay, which is a respectable choice, I’d just like to know which ones looked like they do in the game and which ones didn’t.

[@marcospinheiro352]

I love these episodes! And this new Stegosaurus video really surprised me, especially the tail tip's new posture. Sophie is indeed a marvelous and impressive Stegosaurus specimen, even that she's not fully grown. For the next dinosaurs, I would love to see the Ceratosaurus, Ankylosaurus, Edmontosaurus, Velociraptor, Giganotosaurus and, in time, the Tyrannosaurus rex (since new research and specimens are revealing more facts and theories of this dinosaur). :)

[@jacknelson6163]

I’ve always been fascinated with Baryonyx and you never see much about it. I’d love to see one of these on it

[@jamesharmer9293]

I like the way that "thagomizer" is now a real word. I first saw it on the Far Side many years ago...

[@zeinnerp7609]

I quite enjoyed it. Showing how our view on prehistory keeps changing is another very interesting point in paleontology and paleoart. Talking about the latter...what about an episode on the history of paleoart?

[@ARCtheCartoonMaster]

I must say, this was a pretty interesting episode. It just goes to show how very little we know about the history of life on Earth, and how there's always something new to learn. Personally, I always thought _Stegosaurus_ looked rather odd, with its rump constantly in the air like it's ready to mate, so this new discovery was quite refreshing, and the animal definitely looks better with this relatively typical thyreophoran posture. Just imagine, if any hypothetical, hyperintelligent species will evolve millions of years from now, and they discover fossilised human bones, they might think people with genetic disorders, for example, are separate species, due to having such little evidence to work with! And also, I'm the one who bought you the _Afrovenator_ , in case you guys are wondering. :)

[@Samata94]

Great video, it's fascinating learning all these knew things about dinosaurs. Niiiiice. The best thing about internet as a knowledge platform is the fact that information gets updated in a steadier and more assemble manner than books and papers. in a old video you can write a note in the description, comment and title that knew information is available on the subject. something that isn't possible with paperbacks.

[@xovvo3950]

truly, you bless us. 2 videos within 3 months

[@rafaelalodio5116]

Do an episode about Mosasaur (I Know it is not technically a dinossaur but it fits the show).

[@pedrolelispedrolelis3718]

You mean a Mosasaur or a Mosasaurus?

[@brawlholic9960]

How come we did not know for so long the width of the stegosaurus pelvis? Haven't we found a single pelvic girdle all these centuries? All stegosaurus had such wide hips?

[@earlmaudrie5850]

If I might make a recommendation for some of the merch:just finished silhouettes of the dinos would probably sell pretty well. I know I'd buy a t-shirt with the Spino or Parasaurolophus. Or perhaps some more shirts that explain concepts? Maybe something showcasing gape(from the carno episode) or something demonstrating preconditions?

[@gwoo98]

Love the series. So great and informative. How about an Amargasaurus? Would love to know more about spiny sauropods. Keep up the good vids.

[@ryanmorris2479]

More shorts and updates like this! Great stuff. As usual the animations are great, and revealing as well.

[@MagentaDystopia]

Sophie resides in the natural history museum in London!

[@philipgior3312]

I was always under the impression that the Stegosaurus that is exhibited in situ at the Smithsonian was a very complete specimen.

[@bosniakedisniksic]

I see this being an extremely successful series. Don't get me wrong, I liked your normal YDAW videos but they were sometimes too long and animations are more appealing than a toy figurine. This adresses all issues that keep the "normal" people that aren't as interested in dinosaurs and who don't have 20 minutes to spend on the subject away from your vids.

[@xxXthekevXxx]

Agreed

[@nutyyyy]

Well, it's also very nice to have corrections to older videos, where new more up to date information has come out.

[@lanewaldon6450]

If sophie is a sub adult I can only imagine what she would've looked like all grown up seeing as ontogoney can drastically change the final results of an organism

[@pharinyxtheplant667]

Stegosaurus has long been my favorite dinosaur because of how powerful it looked in it's not so accurate form. Seeing as it looked more like its family, I gotta say I was a bit surprised but I accepted it easily. Love you Stego, no matter what form you are. Also Thank you guys for bringing this episode. The fact that it is numbered makes me excited, can't wait until the next one

[@thegreatgoldfilms6311]

I can live with this version of stegosaurus

[@hateshig1864]

Could you make the yutyrannus next? (Btw congrats on 100k)

[@meneerdekikker9941]

Amazing work Steven! :)

[@laal6290]

Meneer De kikker Nederland

[@astphaire]

Please make more of these in the future!

[@johnjoubert4235]

I just found this channel and I'm super glad I did. I love YDAW. Thank you so much for putting all of this cool information in digestible chunks for the layman.

[@AlisonGChan]

So glad to see a new episode!

[@cryoniccryptid5143]

I reach peak happiness when a YDAW video drops!

[@nihilusdirus]

Can you guys do a YDAW on compsognathus? I love this channel and have been binging it for days

[@rasmusrolling93]

This series is amazing, true to science and everything I love about dinosaurs! I would really like one, or two seperate, videos on Baryonyx Walkeri and Suchomimus Tenerensis. It would be interesting to find out how much we know about them today and how they compare to Spinosaurus for example, did they share any semi-aquatic traits?

[@nerdin1696]

What about what was found in the stego 99 quarry, I thought that was nearly complete and looked like the older view of stegosaurus? EDIT: I ACTUALLY MEANT STEGO A AND STEGO B FROM I BELIEVE BONE CABIN OR NAIL QUARY

[@duvmangg2101]

I like these short, animation filled episodes keep it up!!

[@sockmonkey6666]

Question: Has anyone ever reconstructed a Steg with the plates in a single row oriented 90 degrees to the way they're usually shown? Seeing the flat when you look at the animal head on, and the edge when seen from the side.

[@evodolka]

this was an amazing video i look forward to seeing more synapisodes

[@notoriousscoundrel9162]

Do one on the Ichthyovenator or Amargasaurus

[@TheGodOfGravy]

I’ve seen Sophie. She’s an amazing creature and I was surprised to see her as I hadn’t been to NHM since ‘99.

[@8-BallBlues]

Defiantly buying the merch!

[@acereview7968]

Have you done a Pachysephalasaurus YDAW session? Would love to see in regards to Jurassic Park: The Lost World says of the creature...

[@jessicap4998]

Stegling is an awesome word. Sounds like a Pokemon.

[@raiknightshade3442]

Ok but the word stegling is adorable?????

[@miquelescribanoivars5049]

Science Marches On.

[@MaryAnnNytowl]

Like many others here said, I think stegling is a really cute term for the babies of Stegasaurus!

[@HeatherChandlerIHardlyKnowHer]

Now we wait for feather evidence for Tyrannosaurus.

[@riot2136]

Heather Chandler we gonna find what we think is evidence, then it’s gonna be debunked and then we’re gonna find more evidence. I feel like it’s gonna go on forever lol

[@jesusmora9379]

they found a dinosaur tail encased in amber with all the feathers. some evidence is definitive.

[@ettinakitten5047]

I would like to request episodes on Acrocanthosaurus, Amargasaurus, Ceratosaurus and Pentaceratops. If you see fit to make episodes focusing on one or more of these, that would be neat!

[@amberthekeaton.1635]

YES!!!! ITS BACK

[@hitmonchan9607]

God I can't believe Gary Larson is really responsible for a legitimate name of dinosaur anatomy

[@TheMaragorn]

Is there a way you could make t-shirts available that have the same designs as the mugs, license plate and body suit? I adore your art and would love to flaunt these artworks in particular. But I would also be interested in posters of them, if that's easier to pull off. I'm really happy you're making even more YDAW content for us and can't wait for more synapisodes!

[@oneinfinity]

The attitude towards dinosaurs throughout the early 20th century as you describe it always baffles me. I get why the general public might think certain animals would be lame and boring, but how could scientists ever be like "Oh that stupid animal? Yeah that's clearly an evolutionary dead end. Look at all those pointless frills and spikes it has. No reason to study that any further."

[@ayaanbaig5933]

Did you know about how spinos leg size was increased by 27 percent due to parts of sigilmassaur bones being found were the spino legs would've been and also the hip to leg ratios and how the small legs don't fit the hips.

[@KhanMann66]

Ayaan Baig Links?

[@raptorhonks7324]

I'm so glad you're making more of these!! I love shit show so much!

[@Hishoviper]

Can you do Daspletasaurus next? there’s some really interesting and recent discoveries on the new genus’ skull which could make for an interesting episode since I believe has something to do beak development in Coelurasaurs, don’t quote me on this but it’s something like that.

[@ElRenecito]

Please make a video about THE second most famous dinosaur: "Velociraptor". Keep up the good work!!!

[@likira111]

0:33 "stegosaurus has always been an outlier among the stegosaurus" wait what.

[@martijnvanweele6204]

It looks so much better!

[@porsche911sbs]

Cool new format. Any interest in crocodilian evolution (Paracrocodylomorpha)? From the therapod-like _Postosuchus_ to the giant _Deinosuchus_ , you could make an interesting presentation on the subject.

[@Lothaenorixius]

Stegosaurus was always my favorite dino!

[@tophatoctopus1997]

i was wondering if you can cover some of the dinosaurs used in one of my favorite games called the isle. there is currently over thirty dinosaurs in it and you have already reviewed some. there's: Acrocanthosaurus Albertosaurus Allosaurus (reviewed) Ankylosaurus Austrioraptor Avacaritops Baryonyx Camerasaurus Carnotaurus (reviewed) Ceratosaurus Diabloceritops Dilophosaurus (reviewed) Dryosaurus Gallimimus Gigannotosaurus Herrerasaurus Miasaura Ordromeus Pachycephalosaurus (reviewed) Parasauropholus (reviewed) Psicattosaurus Puertrasaurus Spinosaurus (reviewed) Shantungasaurus Stegosaurus (reviewed) Suchomimus Therizinosaurus (reviewed Triceritops (reviewed) Tyrannosaurus Rex (reviewed) Utahraptor Velociraptor

[@Tobascodagama]

Why am I just now learning that "stegling" is the term for a baby stegosaurus?

[@krishideo8185]

Do maiasaura gallimimus plantosaurus and coelophsis and carntsaurus centrasaurus

[@darken2185]

I loved this video! I am a big fan of the series and I'm thrilled that it's back. Can't wait to see more! I'll get one of those mugs from your merch site as soon as I can :D

[@siqxyre8473]

YESS THIS SERIES IS SOO GOOD MAKE MOAR!!

[@Hoshimaru57]

One of these days it’d be interesting to see an episode of the dino featured in the opening sequence of most episodes. Seriously what is that supposed to be? It’s a therapod obviously, but it has that big clunky square crest on its head.

[@Conefed]

I greatly enjoy your work and especially like the art style and the way you show the changes. However, if I may give constructive feedback, in this one you added a motion bounce. While cool, my eyes would get lost in the movement as to what was changed. When it did the transition in the show with all the stegosaurids, it was much easier for my brain to process

[@icupp8844]

WOOOOOO !!!!!! totally getting that new stego Mug !!!

[@Bengy.]

And on the eighth day, God realised that he needed to feed the viewers with something that is of quality, so God made YDAW.

[@Elukka]

I learned things about both Stegosaurus and pdf files today.

[@greydearing]

I must say I still do have a love for outdated dinosaur designs I I mean I like the current ones way more but the outdated ones maybe it's like if they continue to evolve like the African Cryptid which I won't even dare to pronounce its name but anyways that's besides the point perhaps it's possible that in some Faraway rainforest some form of sauropod similar living to a manatee or in South America some small pterosaur still roams I mean it's highly unlikely and I personally don't think so but it's neat just an interesting thought SAS

[@greydearing]

I know this is very stupid but I still find the concept neat

[@Drummajorguy762]

Anything i can learn about my favorite dinosaur is great. thx for the video!

[@brysonbaird6604]

Keep doing these! I love watching them👌🏻
