Amargasaurus: Your Dinosaurs Are Wrong #25

/ 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.

[@YourDinosaursAreWrong]

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 .

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.

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.

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!

[@Vespuchian]

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.

[@firegator6853]

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

[@carlblix7794]

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!

[@diegodankquixote-wry3242]

Pretty sure that first toy is a freakin dragon, not a dinosaur

[@boredomofboredom]

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.

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.

[@ayaanbaig1375]

@@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.

[@sephikong8323]

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

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.

[@SaurianStudios1207]

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).

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.

[@TheGreatDanish]

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.

There's always something left to wonder about. Always new horizons to be explored.

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.

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

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.)

It's always a good day when my favourite dinosaur channel puts out a new video.
