I know you must have other things planned because I know how much research goes into episodes, since that tour of the studio that you guys did a while back, so just a request.

I actually lost my breath for a moment. The iguanodon is my favorite dinosaur and my friends actually hate when they get brought up because I geek so hard.
While referencing archaeology not palaeontology, I have just written "the Victorians had an uncomfortable fondness for dynamite" in my dissertation. Probably the best line I've ever written
Thing like this it's what keeps me hopeful for my bachelor's dissertation. I'm nervous as fuck, but being able to reference a literal arms race on a submicroscopic scale is going to be awesome.
I appreciate how you clarified that the workers who theorized the size of the animal weren't idiots just because they were off in their size estimations. I think way too often we like to point and laugh at people from the past who made such mistakes, not realizing we ourselves could or would likely make the same errors as you pointed out.
Ye we are able to use their knowledge as a basis for our knowledge. Humans aren't massively more clever, if at all, than our ancestors we can just build on their achievements.
Exactly this. Science changes so incredibly quickly. I've literally had information from my first year of biochem be retconned on my second year and again in my third year. We build on the wrong guesses of our predecessor to hopefully reach the right answers ourselves. Well, the right answers until we ourselves are proven wrong.
This so much! People of today tend to have a pretty prejudiced view of peoples of the past as being just plain 'dumber' than we are. People of the past were not stupid or less intelligent by any means! They were us, that's it, plain and simple. They just had more limitations and fewer giants' shoulders to stand on, and they became giants themselves. The amount of genius present in designs of early structures, machines, old tools, etc. is completely astounding. When I took apart an old air hammer and found essentially one moving part, just with a series of holes and galleys for air to pass through depending on where the part was, just left me astonished at the ingenuity, of how somebody created something basic to solve a complex purpose. The fact that the basic design of the internal combustion engine hasn't changed in over 100 years should convince anyone that we aren't any smarter than they were, we just have more knowledge.
Honestly it's amazing that the earliest paleontologists to work on Iguanodon got anything right, given that they had absolutely zero context for this kind of creature. Despite getting a lot wrong, they managed to work out that it was an herbivore, the initial size estimate wasn't off by all *that* much, and they even figured out that unlike any modern reptile, it chewed its food, and they even pieced together roughly how it did so.
This happens to this day in some fields. I know a guy who walked around a meeting with some a strange insect, asking anyone to tell him what it was. Turns out it was an extremely odd basal true bug. Same guy did the same thing a few years later with a hermit crab parasite. That one turned out to be a collembolan.

As a Belgian who has been obsessed with dinosaurs ever since I was a little boy, and a big fan of this show ever since I found it a couple of years ago, I can not tell you how long I've been waiting for this episode. I was so excited when it was announced that Iguanodon was next. And now that it is here, I can say that I loved this episode. This talk may not be dumb, but I will gladly give it the thumb.
The iguanodons in Brussels were probably the first dinosaurs I ever saw outside of a picture book back in primary school, so it's amazing to see an episode on them mentioning the ones from Belgium.
Fantastic episode as usual! There is actually one more Non-avian dinosaur used on a coat of arms, the Russian Chernyshevsky district has a Kulindadromeus rampant on its coat of arms.
The more I learn about science history, the more I feel suspicious that any time a woman is mentioned in passing (like "oh, my wife showed these rocks to me and _I_ figured out they were significant!"), it's likely she was waaaaaay more involved than she ended up being given credit for, especially the farther back in history you go.
Good point. Although that last sentence isnt true. For example late medieval womens possibilities are greater then 19th cent ones in quite some points in europe. Emancipation isnt one straight climb. As is nothing really in history. Modernity is not at the top of a straight incline in every regard. Even if it wants to be.
I've recently been binge watching this show and I must say - the graphic profile has been adapted with great success! The quality of this episode (besides the actual content) is so nice to look at! Great work, from one graphic designer to another!
I'm way too late to the conversation, but as a pet bird owner who sadly buried many birds (pets and wildlife rescue) they just kind of do that. When they're actively dying they bend their head back like that. Some mammals do it too.
The idea of combining a prehensile tongue with a chopping beak would make iguanodon lunchtime more like a horror film! Bloody tongues falling all over the place
Aah so that's why snapping turtles that have a sharp scissor like beaks and use their tongues as lures all have no tongue left...? you make no sense m8
Their tongues aren't prehensile in the way a giraffe's is. Generally animals with beaks and without soft lips can't stick their tongues out of their mouths.
@@psilovecybin5940 Snapping turtles dont have tongues long enough to come close to their beak. That argument makes no sense, even more so when you consider the original comment is clearly joking.
I love the way Iguanadon has stayed relatively popular in dinosaur media after all this time still appearing occasionally in games and movies to this day. The main reason I mention this because certain early dinosaurs get barely any love anymore for some weird reason. Megalosaurus needs a lot more love imo
In my opinion, this has to be one of the greatest RUclips channels available nowadays. As a person who graduated both in the fields of science and visual arts, this kind of content is just the holy grail. Thank you for your educational service! Cheers from Portugal!
A small nitpick at around 52:00 Quadrupeds would actually be less likely to sink into loose soil than bipeds because they spread their mass over 4 points.
(1) This is by far the best class on Paleontology I've seen on RUclips. Thank you! (2) I had the opportunity of visiting the Iguanodon fossils in the Brussels Museum. What a sight! I could stay hours just looking at those giants! Even though I understand the necessity and value of displaying casts in place of actual fossilized dinosaur remains, these cause a deeper psychological effect in me. Man, I'm really looking at what once was an actual, living dinosaur from millions of years ago! Again, it was a remarkable experience.
Iguanadon was one of my favorite dinosaurs as a kid, and I had the upright, spike-thumbed version fixed in my head, so I was surprised to see you criticize it, and then fell in love with the whole story of how we came to better understand iguanadon, and it's still one of my favorites, just in a different way.
Thank you! I've always struggled with the various descriptions and graphics of it that I've seen, but this actually shows what is going on. Super helpful!
As someone who works a bit with both source criticism and dissemination of science this video really impressed me. Super complex and narrow concepts and ideas really come to life in a way that is interesting to people who aren't biologists or paleontologists. Kudos for this.
I really enjoy the way he puts things into context. He always reminds us not just WHAT happened throughout the history of researching the animal, but WHY the researchers thought the way they did. It's so refreshing to have things framed that way and not "hurr hurr past scientists dumb because they don't know what we know". Keep up the great work!
I am from Maidstone and went to the grammar school there. That coat of arms was on our school uniform. Strangely enough I just found out that the site of where it was dug up was long since built over with housing estates where one of my friends lived. The iganadon is still very famous and there is a cast copy of it in the local museum - which along with a smuggled mummy from Egypt is one of the two main things to see there.
The Iguanodon wastebasket taxonomy phenomenon was far more wide-reaching than just Lower Cretaceous taxa. By the early 2000s, some workers still apparently classed Late Cretaceous taxa as Iguanodon, as is inferable from certain documentaries at the time, like how Dinosaur Planet referred to their Rhabdodon (an ornithopod more basal than Iguanodon) as a species of Iguanodon. Likewise, Late Jurassic taxa, like the British, hilariously-named Cumnoria were also at one point lumped within Iguanodon.
I know there is no chance that this is true, but my mental cannon about Bernissart, is that the iguanodonts used the place as a "elephant graveyard" sort of thing. Which i think could be a pretty cool behavior
You may or may not know this already, but it turns out that elephant graveyards are the results of flooding pushing elephant corpses into the “graveyard”. The true nature of the area is that a whole bunch of bodies get caught and remain in that area, and the fact that so many elephant remains are found there is notable simply because elephants are big and noteworthy.
@@KnufWons not even, it's not a case of misreading the evidence. There is no evidence. There is not a single example of an elephant graveyard ever found. It's an idea that comes from old pulp stories of darkest africa and people just accepted the idea and it stuck in the cultural consciousness.
The crystal palace “pseudo-beak” kinda looks like they were using rhinoceros lips as reference, which would make sense since they gave it a nose horn as well. Also, maybe the iguanodon bonebeds are a sort of “elephant graveyard.” Maybe older iguanodons went to the swamp in search of food that was easier to chew, and ended up just dying of old age in that area?
I was thinking something alone the same lines. And maybe the occasional younger adult iguanodons were badly injured or ill enough to be abandoned by the herd, and relocated to this area, whereas juvenile members of the herd would be looked after right until death due to maternal instinct. It's hard to think of a reoccuring natural disaster that would only affect such a specific area and demographic, so it does seem to feel somewhat intentional. Although as humans we are prone to seeing intent where there is none.
When I was studying at Cambridge in the early ‘90’s I had a friend on a similar course to mine whose name just happened to be David Norman and who kept getting letters from children about dinosaurs in his pidgin hole as they were addressed to David Norman, Cambridge University as far as I am aware they were all forwarded correctly.
Well, it gets even weirder, because something like this happened more than once with the same kinds of animals. We have a mass deposit of Iguanodon and Mantellisaurus here in Germany as well. It contained around 15 individuals according to Norman's paper. Actually it seems that the sediment containing them also sank into a karst fissure. The similarities don't end there, because all bones are pyritized. It's all very very weird...
13:30 I just wanted to point out that some birds like the Friarbirds (genus Philemon) for example the Noisy Friarbird (Philemon corniculatus) do have cheek-like soft tissue at the base of their bills although I can't find any research on what kind of selection pressure gave them those weird cheeks nor do I know if there are osteological correlates on Philemon corniculatus' skull. Worth investigating !
Only 15 minutes in and I’m already sad that it will be over soon. I don’t want it to end. I wish there could be a new Your Dinosaurs Are Wrong episode every week.
Just discovered this series, love to see it! Would love to hear an episode on troodon, or possibly the strange humanoid-dinosaur image that always seems to accompany troodon.
Wait, is this a very high quality video on a very interesting topic with a good intro, filmed with a very good camera with a professional script and a pleasant presenter/host with a good sense of humor? *Why are there so few views and subscribers?* P.S. Thanks youtube recommendations for showing it to me
I have been waiting for ages to see this and loved every last second of it! Thank you for all your excellent work and for taking your time to make this happen!
Great episode. Though I was distracted by that Barney in the background, I still managed to digest all the information in this way too short episode. I look forward to part 2! :P
"Talk Dumb, Get The Thumb." This needs to be put on a sticker, shirt, or button with a YDAW illustration of Iguanodon. I will buy it all. Make it for Iguanodon's 200 year discovery for next year in 2022! It would be perfect and I would again buy it all! :)
Take this as you will; your site has become "comfort media" for me. I suppose you could think of yourself as paleontological macaroni & cheese. Thanks so much for the fine research, enthusiasm, wry humor and animation.
Dinosaur coat of arms: Bedheim, Thuringia (Germany) also had a dinosaur (Liliensternus, specifically) in its coat-of-arms. However, it has since been absorbed into a larger city that no longer bears a dinosaur in its heraldry. Chebulinsky Rayon, Russia, has a Psittacosaurus. Saky, Crimea, features some kind of sauropod for some reason. There are no sauropod remains from Crimea afaik, so this is puzzling to me. Drumheller, Alberta, had a proposed one with a T. rex but that was not adopted.
So basically iguanodons in Disney's Dinosaur are most scientifically accurate depictions in popular media, if you ignore that they give them lips and not beaks.
I’m a new fan but I already watched most of the series, I love how detailed and how you see the creature change into something that was real, would love to see sarcosuchus or baryonyx
This is the 1st episode of YDAW I've come across and it's AMAZING! The quality of the science, the animations, the illustrations and the presentation of the material are all just brilliant. Well done.
May I suggest spinosaurus? I know the research would be frustrating, as the reconstructions change about every year, but I think it's a very interesting topic!
Considering that they only just found a better preserved tail within the last year or two (not to mention one of the best examples of it ever found being literally bombed) this would be a super interesting one.
I love the unedited pauses and the speaker's pace in this show. It makes it much easier for me to digest the information without the constant, back to back rapid fire information thats been edited together without natural breaks.
I wrote a paper on this. The way they moved was by way of moving the mandible up towards the Maxilla, and when in contact 2 specific bones in the upper skull moved independently. I'll link a video that shows this. Here it is: ruclips.net/video/6Sr5is7-wdk/видео.html
God I love this channel so much. Definitely becoming a patron when I can afford to. So stoked to finally get the Iguanadon episode and it was even more interesting than I expected. Can't wait for the next. Also, "talk dumb, get the thumb" needs to be on some merch asap lol
Hey thanks so much for this video! I am running a D&D game set in the land of Chult (where Dinosaurs are prevalent in the jungles) and, while nothing about D&D is "scientific" I am still attempting to depict these dinosaur tokens I am using as making as much sense as possible based on current science as possible. This was SUPER helpful with my Iguanodon token art. Great video and so informative!
From what I can find its rather complicated. Basically a 2008 paper claims these fossils to not be of Mantelisaurus but instead of a new species that they name Dollodon. This paper has, however, been heavely criticised by other researchers and is not universialy accepted. I'm guessing the museum, however, has opted to accept the new name.
Huzzah! Your work is always the best. I knew you were going to bring up Sternberg's Mummy Edmontosaurus. I'd love an episode on Edmontosaurus itself, but what I want most is an episode on a Plesiosaur.
This episode is less "your toy is inaccurate" and more "your toy is a springboard for launching a conversation about the formation of paleontology as told from the perspective of THE OG dinosaur", won't catch me complaining tho XD
My amateur intuition of a thumb-spike is that it seems pretty multi use: - intraspecific competition - defense against predators - rooting in ground for tubers maybe? - could defo be for breaking into woody materials
Yep, same for Ceratopsians, Thyreophorans (Ankylosaurs and Stegosaurs) and dinosaurs as a whole to an extent (Theropods didn't have cheeks but their mouths didn't go all the way back to the jaw articulation, there was a lot of muscle after all).

The crystal palace “pseudo-beak” kinda looks like they were using rhinoceros lips as reference, which would make sense since they gave it a nose horn as well.
Also, maybe the iguanodon bonebeds are a sort of “elephant graveyard.” Maybe older iguanodons went to the swamp in search of food that was easier to chew, and ended up just dying of old age in that area?
I was thinking something alone the same lines. And maybe the occasional younger adult iguanodons were badly injured or ill enough to be abandoned by the herd, and relocated to this area, whereas juvenile members of the herd would be looked after right until death due to maternal instinct. It's hard to think of a reoccuring natural disaster that would only affect such a specific area and demographic, so it does seem to feel somewhat intentional. Although as humans we are prone to seeing intent where there is none.
I'm a simple person. I see Iguanodon, I click.
When I was studying at Cambridge in the early ‘90’s I had a friend on a similar course to mine whose name just happened to be David Norman and who kept getting letters from children about dinosaurs in his pidgin hole as they were addressed to David Norman, Cambridge University as far as I am aware they were all forwarded correctly.
Well, it gets even weirder, because something like this happened more than once with the same kinds of animals. We have a mass deposit of Iguanodon and Mantellisaurus here in Germany as well. It contained around 15 individuals according to Norman's paper. Actually it seems that the sediment containing them also sank into a karst fissure. The similarities don't end there, because all bones are pyritized. It's all very very weird...
9:10 that ain’t no iguanadon. That’s the rhedosaurus from the beast of 20,000 fathoms.
13:30 I just wanted to point out that some birds like the Friarbirds (genus Philemon) for example the Noisy Friarbird (Philemon corniculatus) do have cheek-like soft tissue at the base of their bills although I can't find any research on what kind of selection pressure gave them those weird cheeks nor do I know if there are osteological correlates on Philemon corniculatus' skull. Worth investigating !
“Are you watching a dinosaur toy in Dino clothes talk about lizards?”
YES.
Only 15 minutes in and I’m already sad that it will be over soon. I don’t want it to end. I wish there could be a new Your Dinosaurs Are Wrong episode every week.
I really like the highly stylized and useful animation on these videos! GREAT!!!!!
11:27 damn I wrote a paper on this for D. Altus. Memories
The way you talk and explain things puts me at complete ease. You make exploring this special interest of mine so much fun, thank you.
As a Belgian, I couldn’t be more proud of this documentary, I always felt very connected with the history of iguanodon.
Just discovered this series, love to see it! Would love to hear an episode on troodon, or possibly the strange humanoid-dinosaur image that always seems to accompany troodon.
Wait, is this a very high quality video on a very interesting topic with a good intro, filmed with a very good camera with a professional script and a pleasant presenter/host with a good sense of humor?
*Why are there so few views and subscribers?*
P.S. Thanks youtube recommendations for showing it to me
I have been waiting for ages to see this and loved every last second of it! Thank you for all your excellent work and for taking your time to make this happen!
It has been so long! So excited to see this. Hope you guys are on a roll now to make one of these every month or 2.
17:46 Liliensternus is also on the coat of arms of Bedheim, Germany
17:36 Nope, _Erectopus_ is on Louppy-le-Château's coat of arms.
Great episode. Though I was distracted by that Barney in the background, I still managed to digest all the information in this way too short episode.
I look forward to part 2! :P
'talk dumb get the thumb' would be an amazing shirt
That hand animation at 48:30 is pretty sweet!
"Talk Dumb, Get The Thumb." This needs to be put on a sticker, shirt, or button with a YDAW illustration of Iguanodon. I will buy it all. Make it for Iguanodon's 200 year discovery for next year in 2022! It would be perfect and I would again buy it all! :)
This is the first ydaw I've ever watched, and one of the longest RUclips videos I have ever watched. Awesome show. I enjoyed it from start to finish.
YAAAAAAAASSSSS!!!
Finally, a critical look at one of the dinosaurs with famously problematic restorations.
Take this as you will; your site has become "comfort media" for me. I suppose you could think of yourself as paleontological macaroni & cheese. Thanks so much for the fine research, enthusiasm, wry humor and animation.
The episode I’ve been waiting for since it was often out in the credits of old videos!
Dinosaur coat of arms: Bedheim, Thuringia (Germany) also had a dinosaur (Liliensternus, specifically) in its coat-of-arms. However, it has since been absorbed into a larger city that no longer bears a dinosaur in its heraldry.
Chebulinsky Rayon, Russia, has a Psittacosaurus.
Saky, Crimea, features some kind of sauropod for some reason. There are no sauropod remains from Crimea afaik, so this is puzzling to me.
Drumheller, Alberta, had a proposed one with a T. rex but that was not adopted.
excited for sequel! Iguanodon 2: "No, they did not have wings."
So basically iguanodons in Disney's Dinosaur are most scientifically accurate depictions in popular media, if you ignore that they give them lips and not beaks.
17:47 the flag of Chernyshevsk, in Russia has a Kulindadromeus on it
"talk dumb, get the thumb"
Liked and subscribed just for this.
I’m a new fan but I already watched most of the series, I love how detailed and how you see the creature change into something that was real, would love to see sarcosuchus or baryonyx
This is the 1st episode of YDAW I've come across and it's AMAZING! The quality of the science, the animations, the illustrations and the presentation of the material are all just brilliant. Well done.
17:43 Actually, Russia's Chernyshevsky District has Kulindadromeus on its coat of arms!
Wow, you two absolutely crushed it with this episode.
May I suggest spinosaurus? I know the research would be frustrating, as the reconstructions change about every year, but I think it's a very interesting topic!
Considering that they only just found a better preserved tail within the last year or two (not to mention one of the best examples of it ever found being literally bombed) this would be a super interesting one.
Spinosaurus was already done, and he already seems aware of most of the new research
They are certainly going to do an update video at some point but as far as I know it hasn’t been announced yet
I love the unedited pauses and the speaker's pace in this show. It makes it much easier for me to digest the information without the constant, back to back rapid fire information thats been edited together without natural breaks.
Finally! Iguanodon is such a classic. Thank you.
I love that Bertrand got dressed up as David Attenborough for the introduction😂❤
At 11:26, does this mean the left and right part of the lower jaws moved independently of each other, or am I just reading the graphics all wrong?
I'm wondering that too
Yes it does
I wrote a paper on this. The way they moved was by way of moving the mandible up towards the Maxilla, and when in contact 2 specific bones in the upper skull moved independently. I'll link a video that shows this.
Here it is: ruclips.net/video/6Sr5is7-wdk/видео.html
@@arcosprey4811 I just watched that video. That is fascinating. Thanks.
@@arcosprey4811 Wow, that is an incredibly fascinating function! Thanks for sharing!
God I love this channel so much. Definitely becoming a patron when I can afford to. So stoked to finally get the Iguanadon episode and it was even more interesting than I expected. Can't wait for the next. Also, "talk dumb, get the thumb" needs to be on some merch asap lol
6:44 Iquana lizard? Seriously Mantel? SeRiOuSlY?
Hey thanks so much for this video! I am running a D&D game set in the land of Chult (where Dinosaurs are prevalent in the jungles) and, while nothing about D&D is "scientific" I am still attempting to depict these dinosaur tokens I am using as making as much sense as possible based on current science as possible. This was SUPER helpful with my Iguanodon token art. Great video and so informative!
17:46 so your telling me no one has taken the opportunity to officially have a T-rex on their coat of arms?
The one thing I noticed growing up is that there was never a single consistent depiction of Iguanodon and it bothered the hell out of my OCD.
Question: in the natural history museum the 2 smaller specimens are listed as "Dollodon". Has mantelisaurus replaced Dollodon?
From what I can find its rather complicated. Basically a 2008 paper claims these fossils to not be of Mantelisaurus but instead of a new species that they name Dollodon. This paper has, however, been heavely criticised by other researchers and is not universialy accepted. I'm guessing the museum, however, has opted to accept the new name.
Huzzah! Your work is always the best. I knew you were going to bring up Sternberg's Mummy Edmontosaurus. I'd love an episode on Edmontosaurus itself, but what I want most is an episode on a Plesiosaur.
At long last
The iguanodon episode
This episode is less "your toy is inaccurate" and more "your toy is a springboard for launching a conversation about the formation of paleontology as told from the perspective of THE OG dinosaur", won't catch me complaining tho XD
My amateur intuition of a thumb-spike is that it seems pretty multi use:
- intraspecific competition
- defense against predators
- rooting in ground for tubers maybe?
- could defo be for breaking into woody materials
Wow! I didn't know the presence of cheeks were a debate! Is this true for parasaurolophus and other hadrosaurs who are often restored with cheeks?
I know! It really surprised me.
Yep, same for Ceratopsians, Thyreophorans (Ankylosaurs and Stegosaurs) and dinosaurs as a whole to an extent (Theropods didn't have cheeks but their mouths didn't go all the way back to the jaw articulation, there was a lot of muscle after all).
I heard your voice and immediately subscribed.
I would listen to you talk about anything at any time.
FINALLY! ITS BEEN SO LOOOONNNGGGG honestly it's been so long that I think I've gotten a grey hair 😂
Been waiting for this for so long! Thank you for all the content, folks! Already excited for the next video 🎉
All I can say is that this dinosaur is a heckin’ chonker.
Very excited to unveil our interview next month. Excellent work, as always.
Oh ich would love an episode about Ceratosaurus.
It was an Iguanodon senior home and the babies were burying their grandparents
I wasn't expecting a "paleontology with Yoda" VR experience at the beginning.
That Marks and Spencer toy really is allosaurus. It is based on the Zallinger painting in the Peabody Museum. There was a whole set of them.
