Yes!
Wildcard Games should hire you to consult on their dinosaur TLCs. The game developer recently added a Carcharodontosaurus to their Giganatosaurus spawns in game. The models of both seem to have a mix of features from the toys under criticism.
might b worthwhile to pin this :)
You know the videos good when you don't notice it's an hour long until afterwards
The description of a "description" at 3:15 is so well done! Kudos to whoever came up with the sheet music metaphor, it's so fitting yet easy to understand.
"I'm sorry, your skeleton has a bad case... of Giganotosaurus. It's terminal." I lost it lol
I’d love for a doctor to diagnose me with giganotosaurus lmao
Does this mean my bones will be badly preserved?
4:15
Terminal 107 Giganotosaurus. I don't know what that means but it's bad.
@@darklordstan6154 Additionally, you will have to wait decades for someone to describe them
this series has always been awesome but i can’t help but be blown away by the production quality these days
I am still blown away from their videos 9 years ago too.
Yea
It was always above average
I love how this episode is essentially Steven’s decent into madness
Giganotosaurus having substantial beans is the kind of good news I wasn't expecting today
Your frustration aside this is probably the best episode of Your Dinosaurs are Wrong (and probably the most unexpected tbh). How you pieced together as much as you did with minimal research on the particular animal is honestly just phenomenal
So appreciative of all the research and animation that goes into these. This is one of the best educational channels out there.
You said it.
Agree 100%
full ack
Based
i agree
That opening scene is genuinely brilliant
"A nerd book, for nerds" genuinely made me laugh. I've been eagerly awaiting this episode since you posted about it on Instagram, and it did not disappoint. I really enjoy how much detail you go into in these videos.
omg I cracked up. As if YDAW wasn't also for nerds [affectionate]
Right? Haha those nerds! … 😅
Yeah, I had my doubts about Giganotosaurus at first, but I am happy to be disappointed.
I always love how you refer to dinosaurs as "animals" not "beasts" or "monsters"
It really puts the proper perspective on these old animals we share a kingdom with
Similarly, the description of what animals the giganotosaurus might've eaten, been eaten by, or competed with throughout stages of its life cycle gives a very vibrant picture of the ecosystem as a whole. Really appreciate all that context!
is he guilty of calling them reptiles though?
@@andy-the-gardener Dinosaurs ARE reptiles. Birds ARE reptiles. Neither are incorrect.
💯 👏👍
If they were alive today ever single time the carnivorous ones decided to eat it would be equivalent to a natural disaster
Y'know during the downtime between regular episodes of this show, once every couple of weeks i'll go check the channel and then get mad that theres no new video. But then everytime a new video drops within the first 5 minutes i'm always like "oh right that's why these videos take so long to make, they're incredible, include so much research, expertly written scripts, flawless animation that despite being quite cartoonised still manages to do such a better job than anything else i've seen of showing the important details and how our perception has changed over time.
Killer content yet again guys, please continue knocking it out of the park regardless of how long we need to wait for the next hit!
I declare this a very good comment.
At last! Chinzilla revealed!

Giganotosaurus really does share the same chad-meme jawline as Godzilla from 1998 lol
@@SarastistheSerpent Yeah it does XD
Giganotosaurus has been one of my all-time favorite dinosaurs ever since I learned of it, so it's fascinating to see all the nuanced ways our understanding of this animal (and its relatives) have shifted over the years. Thanks for providing such a thorough breakdown of this giant theropod, and here's to hoping a full description of the holotype is coming soon!
As a Gurren Lagann fan and a Godzilla fan, I just wanna say I love your profile dude
So arya glad that it lives with a giant sauropod after all?
Dinotopia made me love Giganotosaurus, and now I can appreciate a scientific perspective on the animal.
I'm from argentina and last year I was traveling by el chocon. Love dinos so I had to stop for the museum and it was closed for repairs, but they were digging up a titanosaurus femur really close by.
I got to actually touch and see a bone about 70 million old. Needless to say it was the best day ever.
Campeones del mundo y tenemos el giganotosaurus 🇦🇷😂⚽
Update. I just saw at the end of the video about the dugged up titanosaur of 2021. That's exactly the one I saw, it was amazing.
It's really sad to know argentinian paleontologists don't get enough founding to dig up these incredibly important new fosiles (this were actual words from the lead paleontologist in the excavation). Hopefully that changes in the future 🤞🏽
@@lucasdelyerro6496el giganoto es mas pequeño en comparación al tyrannosaurus rex pibe.
Amazing video as always, thank you for making this! As someone who's reconstructed Giganotosaurus, I thought I'd comment on the height of the neural spines (mentioned 50:50) - Tyrannotitan and Mapusaurus preserve complete dorsal neural spines, detailing pretty tall neural spines (though not quite to the extent in Acrocanthosaurus). It's mentioned in the Concavenator detailed description that the dorsal neural spines in Giganotosaurus are broken off, so I thought it best to use these two related taxa to fill in the gaps :)
Seen your skeletals across various social media for a good while now. I know there's not much between them given the format, but have to say I've always really liked your presentation above many others. Inostrancevia in particular was helpful given the general lack of coverage for non-mammalian synapsids. Keep up the good work mate.
@@armata_strigoi_0 thank you, that means a whole lot!
Giga with acro AND concav spines
The cross section views showing how the musculature wraps around the vertebrae are brilliant. That little piece of context goes a long way to showing why the shrink-wrapped reconstructions are so bizarre. Thank you for your time and research. I hope the holotype gets a better description soon! It sounds like the new material really helps though.
Also, nerd books for nerds cracked me up. 🤣
I think this might be my favorite episode. It's a good thing to embrace the uncertainty inherent in parts of paleontology, after all.
You cited more papers for this than I did for my Master's thesis.
Hey, if it produces episodes this good, this detailed and this long, I'm perfectly fine with the gap between episodes. Even more amazing than your usual efforts, and that's a remarkably high bar to beat!
Many, many thanks to you and Liz both, as well as to all the patrons, with much regrets that I can't afford to support you this way as well.
The fact that Charcharodontosaurids exist in the public eye SOLELY to compare them to tyrannosaurus rex specifically is so fascinating to me, T-Rex and "velociraptor"s may as well be the only dinosaur that exists to most people.
Don’t expect much from most people, it’ll save you a lot of disappointment.
This is, of date, perhaps the most comprehensive overview of giganotosaurus based on latest findings. Good job telling us what we know and don't know. Thanks!
"I'm sorry. Your skeleton has a bad case of Giganotosaurus. It's terminal."
The herbivore minding it's own business: "Wait, what?"
nothing makes me happier than finding out that it's possible that some theropod dinosaurs had actual toe beans
I remember when my grandmother printed off a news article about a Mapusaurus reconstruction in 2007 or so. I was only five at the time, but Mapusaurus remains one of my favorite dinosaurs to this day.
I love how new jakapil is, and Stephen took the time to include it and give it an illustration. Some of the other paleoart I've seen has it with a "beard"/covered underbelly with those filament style feathers. Not sure how accurate it is, but boy is it cute. Like a giant dinosaur pangolin
Kind of sad that after all this time we do'nt even have a full skull of giganotosaurus. Love these videos, as someone who has only recently rekindled his love for dinosaurs
Steven transcends YT personality. I genuinely file him away in my brain alongside science entertainers I grew up with like Don “Mr. Wizard” Herbert and Paul “Beakman” Zaloom.
Thank you for such a generous treatment of Giganotosaurus. Information on dinosaurs, intended for adults, seems to be in short supply on TH-cam.
That animation at the end always blows my mind. It's crazy to see how the exact same dinosaur's appearance has changed based on improvements to our scientific understanding of it.
I thought carcharodontosaurs were called shark toothed because they had the most laterally compressed teeth of any therepod dinosaur discovered. The most effectively evolved for cutting, like many shark teeth are shaped.
I really love allosaurids, and carcharodontosaurids their antobital fenestra is almost like a gothic style arch. The finite analysis imaging of allosaurus shows it effectively removes stress from the maxila and dumps it into a thickened skull roof.
43:08 I’ve gone to the Fernbank Museum and volunteered there for years and I’ve always wondered about that bizarre arm reconstruction their mount of Giganotosaurus has. Thanks for explaining!
Many sauropod skeletons probably did experience a terminal case of Giganotosaurus
Something else interesting about the Cenomanian is that there seems to have been very low faunal endemism between South America and Africa (likely due to their still recent breakup). Dinosaurs found in North Africa between 100-95 mya often have direct counterparts in the Río Limay group; big carcharodontosaurids, giant titanosaurs, rebbachisaurids, and both large and small abelisaurids, while the Alcântara Formation in Brazil preserves many of the same types of giant fish found at Kem Kem and Bahariya, as well as Oxalaia, a spinosaurid known only from its snout tip that is thought to be a close relative of Spinosaurus.
Greatly appreciate the segment where you show what animals Giganotosaurus coexisted with and how it would have likely interacted with them, as well as the one where you describe its environment. It is so important to depict animals as part of an ecosystem and not just in a bubble. At least for me it matters a lot to not just have a picture of the animal but everything around it too.
I love the added analysis of where the animal sat in the food chain of its ecosystem/what we've found in the various formations. Sometimes, thats' the hardest information for a layman to locate.
Yes, the only thing I was feeling was missing was an average sized adult homo sapiens figure as comparison, always allows size to be put so much better into context in my opinion.
Well, barring any miracle Giganotosaurus is definitively the Candeleros Formation's apex predator.
Carcharodontosaurids have grown on me a lot recently. Always saddened by the fact that we ultimately don't know a whole lot about them and they usually just get written off by people as "the big predators before t.rex replaced them", which always came off to me as a shallow way of viewing dinosaurs.
That Sesame Street sketch had me in stitches.
Great work as always, well worth the wait. I know this one took you guys a while, and was full of trials and tribulations, but I hope you know that it was all worth it in the end. 😄😃
Ydaw uploading a proper toy episode is like christmas when I was a child -Happens about as often but is always worth the wait.
The puppet acting is great 😂 I love it!
I love this channel because he goes into the descriptive process so deeply. Dinosaur reconstruction is practically more an art than a science, though researchers are constantly creating methods to more consistently identify "trends" that help define an animals function. It still involves a lot of standing back, looking your reconstruction over and asking yourself if it feels right. And that often depends on what function you're expecting of an animal. Is it a carnivore or an herbivore? Does it browse or graze or both? Does it hunt? Does it scavange? Is it social, or solitary?
These suppositions form a framework of what the reconstruction should look like - especially in fragmentary remains.
The rest is marketing. Research requires money. You often have to announce some special 'feature' that makes your specimen interesting or important to attract the funding you need. Hence the toys, the announcements of 'bigger', longer, heaviest, strongest... Hype.
And over time, a picture forms as more evidence is collected. When public interest wanes, research grinds to a halt.
really neat and concise response. do you have a history with paleontology?
In fact the giganotosaurus was not “bigger” than Tyrannosaurus rex.
@@rodrigopinto6676 it was longer but less massive wasnt it? thats what i remember
@@toottoot7316 “it was longer” wrong T. rex and giga same length
@@rodrigopinto6676 huh, am i just misremembering something or is that a estimate more recent than say about 2008 because thats when i remember the "dinosaur bigger than Trex" thing becoming popular here and when i looked into it i was because of length
When an "educational" video is so intriguing you don't notice it's an hour + long.
It is educational...?
The opening scene with the varied pronunciations of 'Giganotosaurus' was beautiful! It would've been funnier though if at one point he just said "Gigachadosaurus" XD
This video was exactly on time, I checked last night because I thought I hadn't seen one in a while and low and behold this arrives only a few hours later.
Really fascinating stuff. I love how messy and yet robust our understanding of animals that have been dead for millions of years is.
And most of all I love the bit at teh end, adding context to what other species lived in and around the area that the subject lived in. It was my favourite part of the Styracosaurs video too, really builds out the biodiversity of the prehistoric in a way I don't usually see in other dinosaur educational media.
Gurney has a TH-cam channel where he shows some of his paleoart process. He relies a lot on referencing physical models, and some of the models he used are very clear in his paintings. I think with the Giganotosaurus he just used a Tyrannosaur of sorts as main reference material then modified it into a Giganotosaurus, rather than switching to Giganotosaurus at the last minute.
That's bad ass that a dinosaur was named after a dragon from A Song of Ice and Fire AKA a "nerd book".
Great episode!! Very long but comprehensive!! I like how we took a tour through Giganotosaurus's ecosysterm, just like we did with Herrerasaurus.
I love that all the groups of large theropods kind of arrived there differently. Like, if it was an RPG
Carcharodontosaurs are the players that chose the build with high base stats and leveled up naturally
Tyrannosaurs are the players that started off with a speed/stealth build and decided mid-game they wanted to be tanks instead so they grinded levels like madmen
And Abelisaurs are the mid-level players that stumbled upon a huge bounty of XP at once and thought “aw shucks, why not?”
and megaraptorans were the players that decided they just wanted to be different from everyone else by choosing to increase the size of their arms...while still borrowing a few techniques from others
1 hour 15 minutes on Giganotosaurus, YDAW knows how to treat us well
This is like kind of unbelievable that this video exists; the amount of work put into this is unimaginable to me.
When this got publicly released, it was like Xmas morning to me! Thank you for being an absolutely wonderful bright spot in a dreary world.
Dinosaurs are. So cool.
It appears to me, that Giganotosaurus was more designed for a heavy strong grasping bite than Allosaurs or other Carcharodontosaurs. This seems supported by the solid square chin and the heavier bone structure of the upper jaw.
“Boxy carnasaur is all the rage these days, I miss the classy notched triangle look of years passed”- overheard at NYC fashion week
7:32 I was in Villa el Chocon in the Municipial paleontological museum Ernesto Bachmann, there was a cool reconstruction of a Carnotaurus in the entry.
There was also the Museum Carmen Funes, its only 1 or 2 hours from Villa el Chocon, there was another Giganotosaurus there, along side a Argentinosaurus!
Absolutely incredible episode with massive high quality information. i myself stumbled upon that 2021 paper that used toy dinosaurs, and i was wondering"hey how do they know they are accurate enough?"
I wonder if the potential presence of a nasal boss indicates that these animals performed intraspecific combat by shoving each other with their heads like tyrannosaurids are theorized to have done?
Absolutely worth the wait, you guys did an amazing job.
Even though the uploads are infrequent, my views are frequent. I will always wait as long as i need to watch these masterpieces
I noticed you have a Definitely a Dinosaur Edmontosaurus "Anatosaurus" in your collection, could you cover Edmontosaurus sometime? It would be nice to see you cover another true Hadrosaur.
Loved the thoroughness of this episode, I think you made the right choice in covering the ambiguities and why they're ambiguous - rather than just saying "we only know so much, your guess is as good as mine", it gives some idea how much work and thought go into trying to reconstruct despite limited description
G for Go-Jira ( more commonly known as Godzilla) which is what I was expecting for a video that dropped on April fools day.
This is cool I watched Discovery's Beyond T-Rex documentary on Giganotosaurus and Carcharodontosaurus just last week. And its examination of how the skeleton was cast and restored was quite interesting to see and enlightening upon that side of palaeontology
Also with that title, I wonder if the Discovery people were behind the push for the T-Rex prize fight thing in the museum exhibition
The Tyrannosaurus rex is still the biggest or largest terrestrial predator to ever walk on earth.
@@rodrigopinto6676 He wasn't denying that?
I dont know if it'll ever stop being weird for me to hear "Meraxes" in science videos
Giganotosaurus has always been one of my favorites. I'm pleased to know I've been saying the name right the past 20-something years 😂
Also good to know that the papers that come out about dinosaurs are not supposed to be understood by laymen, I always feel dumb when papers go around on Twitter and I want to know what's new but can't get past all the jargon
Treat it as Latin class!
It's actually the wrong way to say it. No one says "Jiga" Lol its always Giga at the start and always has been.
@@MistahJay7I think it is more about the Giganoto part of the name, than how the G is pronounced. Somehow people always say gigantosaurus. There's an extra O in there😅
THE OC MARSH BURN 💀
Absolutely loved this episode and the theory of Carcharodontosaurs having a fatty tail and a hump is super interesting!.
My favorite episodes are ones where you go into detail about the dinosaur's environment and the creatures that cohabited with it. I really liked that part of this episode because I am so interested in paleoecology. I hope you continue to do that in future episodes.
“some nerd book for nerds” 😂
Splendid video as always, it seems everyone's fascination with this behemoth spiked especially after JP as well as PNSO's 3rd consecutive release of carcharodontosaurid models.
Love it! Particularly interested in the idea that some smaller dinos, currently classified as dif species, might in fact be less-developed versions of big 'uns like giganotosaurus
This video was one of the nerdiest, and so, therefore, best I’ve ever stumbled on on TH-cam, so I must thank you. As a (still) dinosaur-obsessed 39 year old, I live for this kind of thing. I’m going to watch any video you put up on this series.
Something we really learned only since the discovery of Giganotosaurus is that T Rex was pretty much at the upper limit for a terrestrial predatory theropod, both ecologically and physiologically. The only theropods that were a lot bigger, by height or length, were simply built differently and also occupied different econiches, like Spinosaurus, Therizinosaurus and Deinocheirus. The other big change is that we're getting past the idea of dino on dino confrontations as wrestling matches that could be settled by size alone. Except, of course, in a certain franchise...
I'm surprised nobody sent you the Jurassic world version
1:11:38 the undescribed footprints really highlight how sparse the fossil record is. One can only dream of all the different species of dinosaurs lost to time.
absolutely loved this video, I wish accurate and very indepth paleo anatomy was a bigger talking point in paleo media, and I really, really loved the bit and the end about the ecology of giganotosaurus throughout it's life, I'd actually love to see more episodes having this, or maybe entire episodes about the ecology of formations or the ecology of an animal over it's life and interactions with other animals
Yes!! I fully concur!!
A problem with using teeth to derive temperature via O16/O18 ratios is that we open more questions: Did the animal have lips? How big was its tongue? What was the temperature gradient between braincase/core temp and teeth?
When you have an animal 18 metres in length, standing taller than most houses, and that's considered a "medium" Sauropod, that just tells you the scale Sauropods were operating on at the large end.
Lmao that opening. “Hheeghanotasaurus” 😂😂😂
This video feels less like (just) a description of a dinosaur for us laymen, and more like it's (also) a part of a larger paleontological conversation. This was an amazing episode. Thank you!
This is one of my top 3 favorite dino channels, and the care & effort put into this is absolutely why 😊
I lost it at “its toes would have had pretty substantial beans”
Love the contemporary animals section. Please keep this a constant feature.
I paused this to tell my bf that one of the cool nerd dragons I like has a dino named after it, hit play, and got called a nerd. I love it lmao
Giganotosaurus more like Gigachadnotosaurus
"I'm already subscribed! T-T I can't subscribe any farther!"
The fact that, like, a few days after this episode released, an update in BTD 6 (tower-defense game) added a giganotosaurus is really crazy to me. (a few other dinosaurs too but this one I didn't know existed before so yeah)
One hour long video? Lets bring out the popcorn🍿 AMAZING video, so much fun to learn about these creatures ❤️
The ydaw movie is coming...
At 30:00 "What the Fu-nctional implication of that is" When he started that sentence, I didn't know where he was going.
A new vid at last! Yay! I would love to take a trip to the Field Museum with you folks! Learning you’re not far from me makes me really happy. I didn’t realize there were other Dino enthusiasts in MI! I thought they all bounced to the Hell Creek formation by now. Lol
I was sort of hoping you'd have a toy of that exaggerated, cartoonish, time-and-space travelling monster "Giganotosaurus" from Jurassic World Dominion so you could point out how ridiculous that design is. Oh well lol Awesome episode as always
Ahh! It always makes my day, week, month and year when I see a new way that I was wrong about dinos. Thank you! ❤❤❤
I’ve been waiting for this one and it was worth it! Thank you for taking such time to describe the GigaChad!
I absolutely love this channel! I adore all the work you put into researching and filming and animating this series! Keep up the awesome work!
Release the Giganotosaurus Osteology!
I am so happy there is a new episode. I've watched the whole playlist many times. I really like the animations and the way you guys present things.
I can only imagine how long a video on Tyrannosaurus would be
Longer, but much easier to produce, I suspect.
@@RethShannar yeah, even the most complete tyrannosaurus specimen has been nicely described. And we've had gargantuan papers analyzing it's ontogeny, facial integument, and locomotion. A video about tyrannosaurus will be longer only because we know so much about it.
You did so much work to research for this episode. Seeing the citations pop up on screen is so cathartic
Thanks for another amazing video! I love getting to see more depth and learn more jargon than I would from almost any other source outside an actual published research paper. You make these things very digestible and entertaining; the animations are so well-done and really help make things understandable. Keep up the great work!
I would also like to mention another unnamed giant sauropod from Candeleros, known as MUCPv-251 (Calvo, 1999) only from a partial rib and dorsal vertebra, therefore scaling it is very hard, but it was around Argentinosaurus size, if not bigger! It could be an olderindividual of the same species as MoZ PV 1221, but again fragmentary fossils make this near impossible to tell.
Any day with a new YDAW episode is a good day.
Thank you!
