- / ydaw -- It seems like a weird creature compared to what is thought of as the 'standard' sauropod due to its spines. But when we consider it comes from a group of short-necked low-browsers, Amargasaurus makes a lot more sense!

'YDAW' is a series that makes paleontology accessible to the general public using familiar (but wrong) dinosaur toys. - Наука та технологія
Correction: In the graphic at 11:30 the colors in the key are swapped, blue should say Dorsal and purple should say Sacral, my bad.
If you like our stuff, and would like to help us keep making it, please consider chipping in over at patreon.com/YDAW, or taking a look at our products at www.etsy.com/shop/YDAWtheShop, or by buying Steven a coffee at ko-fi.com/ydawtheshow . All proceeds go back into making the videos you see here!
I didn't notice it anyways, oh well.
Hey, uhh should probably pin this
I'm not entirely convinced that the first toy was always an amargasaurus. It looks like the manufacturers just took the wings off of a preexisting dragon toy that they had in stock.
100%
Was thinking the same: the way he coiled his tail and neck is more like some chinese dragon.
Hi, I'm the one who actually sent it! Turns out the toy is part of a very stylized card series from Spain. I also sent them a Deinocheirus and Protoceratops from the same series which are both also equally weird looking.
Yeah I was thinking along the lines of "it looks like they combined a dragon and sauropod".
@@dracorexion I think i found a tyranosaur in this couch I bought
I come bearing news from the future: a new study suggests a skin sail on the neck spines might be possible after all!
If I had a nickel for every time we've waffled on the reconstruction of a spined/sailed dino... I'd have (at least?) two nickels.
I swear Amargasaurus is REALLY trying it’s best to be the sauropod version of spinosaurus
@@SpiffierShindigsand two waffles
@@theangrycheetoI’d rather have two waffles than two nickels
Skin sails are obviously for absorbing heat from sunlight. Like spinosaurus laying in the water but it's sail could be out of the water gathering heat..
And looking so darn scary to see that guy under the water
"We've known about Amargasaurus for just under 30 years"
"Ok"
"It was described in 1991"
"WHAT"
Here I am still picturing 30 years ago as being early 80s.
How has the past year not been a decade I think of 30 years ago as before 9/11
I keep subtracting from 2000, which for "20 years ago" has some awkward consequences.
My first instinct is still "30 years ago=70's"
My first thought when I hear 30 years ago is 10 BC
Wow yeah I was thinking 70s 🤣
“We have a handful of foot bones”
I love this channel
(Somewhere in the multiverse)
"We have a footful of hand bones"
LOL I love how he laughed at himself 🤣
@@heinzdoofenshmirtz3311 the moment he said it and went silent, I just hoped so hard he would correct himself like this... 😁
And zero footbones. Whereby he means to say "a footful of handbones". Cause you don't hold stuff with your feet.
@@heinzdoofenshmirtz3311 damnit you beat me to it
The successive studies and theories revealing the look and purpose of the neck spines was thrilling. Another excellent episode.
Fancy seeing you here! :D
I love seeing creators commenting on videos of completely separate genre/topic. So cool that we all have diverse and yet still common interests. I remember the Dino inlay on the Gothic Flying V. Love you Colin!
interesting seeing you here carlin
oh wait no it makes perfect sense, you love dinosaurs!
less then a year between two episodes?! WAS IS THIS MADNESS
It's certainly ahead of DI.
@BionicleSaurus hi, I’m a fan of your channel. I didn’t expect to find you here lol
@@BionicleSaurus Eh fair point
THIS IS SPARTAAAAAAAA
i just love that a small sauropod is still as large as the largest land animal alive today
I find your show extremely comforting. I have really bad anxiety issues, and for some unknown reason these uploads calm me right down from a panic attack. I'm not sure why that is, I never was a "fan" of dinos, but it does...just please know that you're really helping at least this human get by, and now I am becoming a fan of dinosaurs!
I'm also a big fan of this type of video. The informal, extemporaneous narration is very easy to follow, despite how much information is being given to you. It's not trying to grab your attention or excite you, it's just telling you neat facts about fascinating animals, like a personal tutor.
I'm particularly fond of the construction-paper-inspired animations.
I think its his very grounded and un hurried speech.
I listen to these to sleep a lot (: I absolutely use this channel for comfort purposes
i like these videos because i just find interesting how bizarre life on earth was and how different from today even though the animals had the same kind environment they were still different
but most importantly im tired of the media showing them so terribly inaccurate and it's hard to find completely accurate dinosaurs sometimes so this channel really helps
I used to suffer from panic attacks and I can totally see how these would have worked, had YDAW been a thing then. I think it's a combination of Stevens calm and 'low affect' personality, the background music and the colour scheme and style of the set and animations. Also, it probably helps that the videos are about something completely unrelated to human life and problems. I really hope your issues with anxiety get better over time!
Not gonna lie, kinda miss our moustachio'd dino friend from the opening.
What kind of theropod is it again?
I think it’s monolophosaurus based on the crest, but it’s pretty generic
Probably a corythosaurus
@@TheAnimalKingdom-tq3sz Iirc, those of us in the discord actually believe Bertrand is supposed to be a Corythosaurus, and not a theropod at all.
Please do an episode on plesiosaurs. They are probably the most common "dinosaur" toy that you haven't done an episode on and I know there are lots of things wrong with them. Thanks!
As of right now Steve and Liz have expressed their want to focus on true dinosaurs for the most part, though they do plan on doing episodes on some aquatic reptiles and pterosaurs that they've recieved.
Amongusaurus
@@dracorexion There's a pterosaur and mammal covered; A plesiosaur isn't a big stretch.
@@jeffreygao3956 Calling dimetrodon a mammal is kinda stretching it, but I get what you're saying
Just go to Loch Ness and see a real live one for yourself!
Pretty sure that first toy is a freakin dragon, not a dinosaur
I can assure you that it's supposed to be Amargasaurus. The toy is from a card/figurine game from Spain. I found and bought the toy to send to them online, along with a Deinocheirus and Protoceratops that are equally weird looking.
This is the cutest sauropod I've ever seen. Good to see some of my grand kids rocking it so well.
Oh my, I am your fan. Could you sign my inner fish?
Tiktalik? I evolved from you and my speicies became a** holes 😊 I miss u :/
@@ormfantanen7451 we can only imagine
One things for sure, the more we discover about dinosaurs the more they seem like "real animals" and less like "monsters."
sounds oddly poetic. congrats
I never really realized how small amargasarus was compared to a person until I’ve seen this video and I’ve known about it for so long.
A new paper that was published this year has suggested the spines were indeed covered in skin.
I don’t agree with that. If it was covered in skin how would the animal defend itself. Bajadasaurus would have used those spikes as weapons.
You guys should do a ydaw oops on spinosaurus especially with the new tail and supposed arms
Could you catch me up on the supposed arms? I read about the tail but missed that bit.
Yesssss
To be fair that could be a yearly thing at this point
@@lucagarciaferrari I can't link it for some reason but if you go on the dinolabs facebook page they have posted images of them. They were confirmed to be real by I think a Canadian paleontologist.
They look pretty different from regular spinosaurus arms (no surprise) with the thumb finger being much shorter. The hands and arms themselves were built pretty powerful but the pectodectoral crest on the humerus was pretty small meaning it had weaker swipes than baryonix or suchomimus. Also from my own crude measurements I got an arm length of 6.2 feet for msnm v4047 but that's my own and I didn't put much time into it.
Please no, not spinosaurus, if they do then hey would have to redo it approximately every 6-15 months which would be very time consuming
YDAW always gets me SO PUMPED about dinosaurs! The research that is presented in such a digestible and accessible way is so valuable for recontextualising my understanding on Dinosaurs over these years.
Is that an Ayame kojo pfp? Lol
When you talked about the potential art featuring these spined dinosaurs with leaves and such stuck on them, it makes me wonder if any plants took advantage of dinosaurs to help distribute their seeds in any way? Like how Burr seeds stick to fur today to distribute themselves.
Yaaas
this animal was specially interesting, and quite a mystery
Agree! Needs more representation in other media
I feel like I would watch a full series of this guy playing Ark: Survival Evolved 😂
That “Amargasaurus” toy at the beginning of the video looks more like a dragon without wings than a sauropod. This dinosaur has always interested me, it’s one of the lesser known sauropod dinosaurs that deserves more recognition than just being a medium sized sauropod that wasn’t as big as the others. The spines on the back (either they were just spines or a sail) makes this animal majestic and really weird for a sauropod. Also appreciate the effort and dedication put into these videos explaining real science behind these incredible animals that are sadly misrepresented too often in pop culture (speaking as someone who likes both scientifically accurate and pop culture depictions of dinosaurs).
finaly after such a long time we finaly got amargasaurus
spinonychus
I shall now try to make (with my mediocre art skills) Steven’s “a good arT”
I think the banding on the tail comes from a "walking with dinosaurs" Episode. "Time of the Titans".
Its been so long he's got grey hair now
There's something so soothing about being able to veg out and let my brain be filled with dino knowledge
They went and turned that first toy into a dragon without wings
I love dinosaurs. I loved them when I was little, then I got kind of bored with them for quite a few years. However, I have been getting back into them and learning more than ever these past couple years. They are just so cool! This series has taught me so much aside from everything else I have been learning from. Keep up the good work!
As someone who really wants to be a paleontologist one day, but is still in the process of learning basic anatomy, I find these videos really interesting! Keep up the great work!
As someone who really wanted to be a paleontologist after I saw Jurassic Park (without the permission of my parents),
but was spoken out of that dream (too),
I hope you succeed.
Bajadasaurus: "Shut up, mom! It's not a phase!"
**listens to heavy metal/punk rock intensely**
The moulds for the earlier Battat dinosaurs have severely degraded over the years. I have that Dan LoRusso Amargasaurus from the original Boston Museum of Science release from c.1996 and it looks so much crisper and more detailed.
"A handful of footbones"
Tremendous
I've been holding off on looking up anything about Amargasaurus so I could be surprised by this episode! Well worth the wait.
These videos are so soothing. It just calms down my over anxious brain with some nice straightforward discussion of science. There’s nothing loud or ostentatious about it. It’s just gentle science about cool animals with some great animations
Every time the model gets adjusted:
"This isn't even my final form!"
Then in 2022 a paper came out stating that Amargasaurus had soft tissue connecting the long neck spines and not keratinous horns.
Absolutely fascinating and well worth the wait! Also, the intro was adorable :) Awesome work, as always!
EVERY single episode of this show is just absolute gold. Thank you for the hard work you put into these!
This show has reignited my love for dinos :) Thank you for all the effort these take! Could I suggest for more Ceratopsian episodes? I really love them, specially Pentaceratops, I've always wondered how their skulls exactly work and if they had beefier necks to hold them! Have a nice day
Steven's voice in the opening of the video made me smile a bit, thanks for that. I mean on top of the thanks for making these videos in general of course, I appreciate you folks.
I'm really glad to hear about the official portrayal of Amargasaurus' neck spines. Another great episode overall.
BTW That children's book you mentioned at the beginning looks very cute.
Always so glad to see more YDAW. This is so wonderful!
Ok so the use of niche partitioning as an example for how uniqueness can be a good thing, especially in a children's book.... UGH this is so damn sweet & kinda brilliant 🖤🖤🖤🖤
ITS FINALLY HERE IVE WAITED SO LONG
So stoked for this. This dino always interested me and there’s so little out there about them in the pop science I read.
You guys need to keep them coming. This videos are so informative and I love the way citations are presented. Awesome job!
My favorite dinosaur! A very interesting one. Usually sauropods are seen as massive dino giraffes but amargasaurus being similar to that of basically a big dino Ibex is so interesting. Fascinating how diverse sauropods actually could be!
Always makes my day when I see a new one of these
This made the rest of my day
Now I really want to have that book from the opening :'D
I love this series so much because it really puts into perspective how much of a gradual process paleontology is. With every single one, we see how our understanding of any individual species grows and changes, and it doesn't ever really put down the early workers of the discipline.
It just accepts "this is what they had to work with, we wouldn't have done any better if we had the same criteria."
Thats something thats missing in a lot of archeo or paleo focused channels, that empathy and understanding of the people who helped build the foundation our modern knowledge is built on.
Even if I wanna go back in time and slap who ever thought it would be a good idea to excavate Troy with dynamite.
RETURN OF THE KING
YAS! Another video! This video about Amargasaurus is really nice and neat. I learned a couple of things from the episode. I can always come to this channel for paleontological comfort or when I forget a specific detail of a dinosaur. The drawings are great, too! Keep up the good work!
to have spikes on the neck is a good defence agaisnt predators that usually goes for the nexk.
semi related, i´ve seen sauropods recently,restored with ridges and some times small spikes ont he bottom of their necks and huge osteoderms on their back and tails. where does that come from and does it have any support in paleontology?
Markus Nävergård Saltasaurus had bony nodes on its back, along with some small spines. It’s a more obscure sauropod despite it’s unique armor, prolly because it’s not a comparatively large sauropod.
Kids today are slowly developing neck horns from staring down at their phones all the time. ;P
These videos are amazing. So entertaining and informative. The production value has recently gone through the roof and I feel like a parent watching their kids grow up. Or, more accurately, a weird adult watching other people's kids grow up.
I really love all the effort you put in your videos, i have learned a lot with your help, so i´m triying to help back a little by sharing your chanel on paleontology groups, this channel needs to be bigger, you totally deserve it
Ever since 2 years of age, I have loved dinosaurs. I came across your channel by accident, but have been thoroughly enjoying with great interest, your talks. Thanks for the sharing!
I like your approach to analyzing the possibilities and the range of truth they have.
I love that you show what each reconstruction would look like and the arguments for and against each one. Super interesting
What I like any this channel is how it communicates to people my favorite thing about dinosaurs: that our knowledge about them is in a constant state of flux. That's what I love about dinosaurs. The uncertainty. Finding out new things that completely overturn old things, or just that ubiquitous "we don't know!" that always comes up with dinosaurs. There's always something left to wonder about. Always new horizons to be explored.
I love this channel, i love this guys energy, whenever i feel sad i know i can come here and get better :)
I think the bands on the tail are inspired from the diplodocus of walking with dinosaurs (which in turn was inspired by iguanas, but I think the toys designers took their inspiration from walking with dinosaurs.)
I don't have time to watch this right now but I *do* have time to drop an instant like and favorite it! I love you, guys, thanks for all of the work you do for this channel!
Man, it seems like only a few weeks since the last episode. I'm glad to see you guys working at a solid pace! I couldn't help but notice the updated diplodocid silhouettes. It prompted me to go check out Scott Hartman's updated sauropod skeletals and realize how cartoonishly goofy the proportions of a lot of these animals are.
Once again, excellent video, keep up the good work
Glad to see more content from this channel. Genuinely fascinating watch, as always, & I look forward to the next video! I didn’t know sauropods with neck spines existed.
I love the entire new format for this show. I hope they can do more videos on this quality more often.
I had a very relaxing and informative half hour drive to work this morning. Thank you.
I like sailed and horned, but for different reasons, like the sailed depiction because it's pretty, and like the horned depiction because it's cool
Yes! Super excited for this episode, I was thinking about this the other day wondering when the next episode would come out. I'm extremely thankful that I didn't have to wait to long. LoL. Honestly, looking forward to this has helped the 2020 blues that have hit me over the past few months. I've probably binged the series 3 times between the Velociraptor episode and this one. Thanks for everything! Heres hoping that we can go for a third episode in 2020! That would be a great way to end this year.
So this video appeared in my suggested videos seemingly at random. Long story short, you basically managed to get me interested in dinosaurs again, a topic I wasn't this interested in for over a decade. Thanks a lot
I love everything about this series I’m so glad it’s still going on
Great video again, the time yous spend on these really pays off
Possibly my favourite channel on youtube. Please keep it coming.
So awesome to see a video on Amargasaurus. One of my favorites. Also loved that animation at the end.
This was packed with way more knowledge than I expected. I need to examine this channel some more.
Missed you guys!! Love the episode. Very research heavy and fascinating!! 👏👏
Man do I love this series. Hope to see another episode this year.
Another great video by another great youtube channel. Please never stop doing these
I love the Style, Narration and especially Set Design of these Videos !
ALways glad about every new episode! Hoping for many more to come!
Glad to see you guys are still going.
It's been *way* too long since I watched an episode of this. Nice to see an episode about Aurorus - I mean Amargosaurus.
soooo glad you’re back! also if we could EVER see steven truly laugh-he makes snarky comments but never busts up. it kills me
Incredible channel, wondering why I never discovered it sooner, Its amazing. Thank You!
So interesting and love your animations that go along with it.
I'd love a video on shrink-wrapping prehistoric animals.
Sooo glad I discovered your newish channel!
Thank you for another beautiful episode!
I loved dinos as a kid and these vids are rekindling that. Thank you.
Last time I remember, Amargasaurus was just a 3d model in jwtg with no shaders and was the size of large saurapods.
I do so enjoy these videos, and the accidental(?) puns are amazing, so never take them out!
Edited to add:
Your channel taught me to say nares correctly, too - I've got chickens (and several other bird species), and when talking to others about them, and caring for them, if they ask about the nostrils, and I tell them about nares, I can say it correctly, now! I always love to learn new information, so thanks for that, too. 😊 I had been pronouncing it like "cares", so it's a pretty big mistake you let me fix.
❤❤
Very educational channel! My twin brother has been a dinosaur nut for as long as anyone can remember, so I'm into dinosaurs by proxy. But that's good, because it was thanks to him that we got some of the anime Dinosaur King on DVD when we were little kids. It's one of my favourite tv shows and has a special place close in my heart; it's because of Dinosaur King that I know most of the dinosaurs I do, especially Amargasaurus. To think animals such as these roamed our Earth, walking on the same land that we do now, all those millennia ago - is absolutely insane and fantastically wonderful.
ark's amargasaurus release:
i'm gonna start this video's whole career
Man amargosaurus is one of my favorite sauropods first got introduced to it in fossil fighters for the ds and loved it ever since I actually have that figure it's awesome.
Hey there, i just found your channel and i love what your doing. The Amargasaurus is one of my favorite dinosaurs so i love you how take the time to explain it. Would you ever do a series about showing its habitat and diet?
We've been blessed by another wonderful upload of a truly wonderful episode about cool sauropods 😭
Great video, as always Steven! 😁
I remember a show called Dinosaur Revolution. The 2nd episode depicted the life of an Allosaurus based on a specimen of an Allosaurus's mandible that was broken and healed crooked. The episode showed Dicreaosaurus and Allosaurus fighting. After seeing the size chart on Dicreaosaurus, I think they made it too big in the show, as it was towering over Allosaurus and Torvosaurus
