CORRECTION: TheDubstepAddict has pointed out that, as of 2016, the isolated feather is not thought to be from Archaeopteryx, so coloration is still up in the air.

Finally! Why did you guys go for so long? I unsubscribe and subscribed 3 times from impatience and then not wanting to miss the next episode 😂
We only have two people working on the series (and all other videos we release) for the most part unless we've taken on an intern or two for a semester. Because we like to be as accurate as possible, and rely on animation, it takes us much longer to achieve the quality we'd like. It's a quantity of videos in a year vs quality trade we're willing to make until we're able to hire more full time staff to help things go faster(non-profit life, yo).
It's been so long I've watched every video in the series multiple times
same!
Psst, you guys know you can drink 5 hour energy, right?
lolz
All birds are dinos but not all dinos are birds
*explodes*
Carrey John Basically the logic here
all clarinets are wood winds, but not all wood winds are clarinets
Yes yes
All thumbs are fingers, but not all fingers are thumbs.
"Life is a writhing, messy, iterative, beautiful experiment."
That was strangely poignant.
Dr. Ian Malcom approves this message.
YDaW: "It was actually quite large."
Me: "Oh?"
YDaW: "About the size of a crow."
Me: "Oh."
😂
My thought exactly. I was hoping Buzzard or Duck at least.
Rooks are pretty big
@@jk844100 but compared to other things around in the Jurassic… they’re hardly a spec on the landscape.
Crows are big birds really
For bird is beeg
"I do like the tarsal scutes" - that's not a phrase you hear every day.
"tarsal scutes" sounds like a country western singer.
Depends on how much YDAW you are listing to I suppose
"Occam's razor is a fine thing, but the universe is a Rube-Goldberg machine."
Is this referring to assuming parsimonious family trees? Because I have a simple answer to that: It's the only tool we have for determining evolutionary relationships between different taxa, barring time machines and a _lot_ of patient interns.
This quote is amazing! Where is it from?
Th-that's chaos theory..!
@@StephenKoplin did you ever find the source for that quote? The _only_ thing that shows up when I search for it is from some forum where one of the people posting there uses it as a signature line, as a quote... but gives no source for it. _~sigh~_
@@MaryAnnNytowl the guy talking in the dino video said it.
Just to clarify, the "worst quality Papo figure" is actually not from Papo, but a knock off/bootleg of Papo's model.
Oh, that makes sense.
Hi Patrick
você por aqui
Any chance you guys could expand to "Your Prehistoric Animals Are Wrong," or YPAAW in general? That way you could also cover pterosaurs, crocodylomorphs, synapsids, and prehistoric mammals.
There's a Pteranodon and a Dimetrodon episode already, and very interesting they are. No need to change the name, it's snappier the way it is.
I wouldn't mind seeing another pterosaur or two - a giant Aszdarchid please, Quetzalcoatlus or relative! Or a pliosaur like Liopleurodon: the dark side of the plesiosaurs.
I'd love a Lystrosaur episode! I think they are awesome, partly as they survived the Permian/Triassic extinction.
You could probably shorten it to "Your Paleofauna Are Wrong".
@@inkmaster5480 snappy, but perhaps a bit brash
I would’ve liked to see a Dire wolf episode.
Huh... I always thought it was just a kinda long-armed, fluffy velociraptor. I should've pictured it more like a funky bird with teeth. This series is re-awakening my kindergarten obsession with dinosaurs.
When youve been binge watching all the YDAW for the pasts few days and they upload a new one
Orion Rodriguez same!
I do that with PBS eons normally, and I have started binging these now since I finished all eons episodes.
31:20 One of the best segments in the entire series. The complete bombardment of information regarding the evolution of dinosaurs and the traits that make all of them unique animals is among the best ways to end a video about Archaeopteryx. This ties into the Dinosaur Revolution, where just because they're old and dead doesn't mean they are just pawns on the pathway to birds.
It's hard to explain exactly what makes it so fantastic to me, but it goes along the lines of: Okay, an animal could have this feature, or that feature, or any other one, but following any of these lineages reveals an entire tree with animals containing that feature, and continuing along a branch reveals animals with a new trait, and others with more new traits. Starting off with a seed, and growing into a giant tree.
I guess I'm just amazed at how varied this tree of life is where no matter WHAT part of the tree a creature is on, there's something unique and complicated that cannot be found on any other part of the tree.
I feel as if every entry in this series expresses more of the scientific backdrop, like the explanation of Cladogram construction, though I also like the idea of a "story", like the bone bed in the last episode. Inference of a detailed history based on evidence is very interesting. Always fun to learn things you didn't know, especially finding the things you thought were right actually weren't!
Great video Steven and the crew, can't wait until the next one.
Thank you!
Totally agree
"Life is a writhing, messy, beautiful, iterative experiment" I love this line.
Professionally, I'm a photographer. I would love to get a chance at photographing an archaeopteryx specimen so I could get the lighting right to show the details... A lot of fossil images don't seem to focus on using optimum lighting for the best representation of details.
Sorry for more rambling. I actually put together a portfolio of paleontological and archaeological photography for one of my college courses, so I'm passionate about the subject. ^^"
Paleontologists aren’t photographers lol
Well, as a palentologist you do need a secondary job.
Photography is also a form of art, and paleoart is a thing
Personally, I'd love to see your work. I agree with you 100%. I have also wished someone would do that for a while. It would be nice to see if they come out as well as I've suspected they would.
I like the idea of Archaeopteryx as a gliding crow that went fishing. This was fun!
I like how it's really un-edited information, everything comes out from him, not from a script. It feels very natural. Like and Sub

"Curse your sudden but inevitable betrayal!"
I clicked and was not disappointed.
I wish I had a teacher explaining things so interesting as you do when I went to school. I’m sure a lot of my fellow students wouldn’t have slept during courses as they did now. Thanks for the interesting presentation. Seeing these things awakens the child in me. I was and still am a dino geek.
Fantastic. Just a little precision, the London specimen have actually a partial head preserved. It was revealed by a work (I don't remember when but before 2000) of a recent preparator that was allowed to cut a part of the archaeopteryx block to expose the parieto-occipital region of a partially preserved skull in the lower left part of the block (Angela Milner). For flying ability, there is always a misconception if Archaeopteryx is a bird a bird would have a wishbone like a bird. But we knows an animal what is flying extremely efficiently without any sternal modification, it is bat. They have a traditional mammal sternum and fly perfectly. Of course the myology and biomechanics is not the same but it is interesting to see how some structures considered as essential are in fact not completely. I don't say, that archaeopteryx could fly as a bat, certainly not, but I only say be careful the animal was possibly more efficient in the air than we can actually demonstrate. There is no doubt that if we have no modern relative for bats and have found only fossils that we have considered them as poor flyers. As I have studied the large ornithocheiroid pterosaurs a lot of misconception have been used for long time especially that the sternum was not developed enough to insert muscles necessary for power flight. We knows today that it is false. All the best.
We need a Dragon Ball Archaeopteryx show after seeing that intro.
Defenitely
YeA! x""D
someone let japan know
I would watch that even though I don't like Dragon Ball!
Pe e
Great video! I would personally love to see you do an episode on Iguanodon, because of its significance to the history of studying dinosaurs, and its varying reconstructions over the years!
Whenever I think of Archaeopteryx I think of the Hoatzin. :D Such a cool bird.
And of course, baby hoatzins have claws on their wings, just like Archaeopteryx!
Though unlike Archaeopteryx, the baby hoatzin's claws fuse together when it grows up.
actually most birds have wing claws: emus chickens hoatzins are the only ones where ive seen the claws but id asume that most ratites and close relitives of chickens would also have wing claws
This is a lot more in-depth than I expected when clicking the video. Have a sub! *gets popcorn to binge*
I find this channel quite entertaining, I always loved dinosaurs and its cool to see them accurately talked about.
Lots of bird feet are pink or blue-grey. imgur.com/a/a0nRy
Yellow and black are common, orange is present in a number of birds, a few have red legs. The blue-footed booby is famous for its bright blue feet. Turkey vulture legs are so pale as to be nearly white. And of course there are various shades of brown.
This kind of variation is why I always like to see modern bird-based coloration rather than bird+lizardy thing coloration on figurines and in paleoart...there's no need to make it look like a lizard to make it look cooler, these creatures are already pretty cool and could have been very vibrant in color.

Don't forget Wilson's Bird of Paradise
Those illustrations/animations are wonderful! Very lovely style, unlike most educational videos.
10:44 They look like they just flew into some Mesozoic glass windows 😂😂😂😂😂
I wish an austroraptor figurine existed! It is my favorite dinosaur.
Jenna Zornes Can tell cuz ur profile pic is the austro from The Isle
TheGamingSepticEye it's a wolf.
..
Never clicked so fast ! I missed YDAW soooo much !
Invincible Nightmare I choose you
If a snake can flatten its ribs and glide great distances, I have GREAT confidence that this feathery boi could at the very least navigate a 3 dimensional biome with great proficiency.
The toys may have evolved a supporting tail just as a Way of making it stand stableely.
26:30 That moment when your phylogenetic analyses features a trait with 5 godforsaken states!
Ziphosuchia are complicated...
Wow, awesome job on this one you two! Steven's rant on the changes in the phylogenetic tree of non-avian and avian dinosaurs was quite impressive xD
When you were going through the tree explanation I was distinctly reminded of the ion engine wiki page in the fact that I had absolutely no idea what was going on but it was still interesting.
I like how he takes his time analysing the toys/figures
I would appreciate it if you did an azhdarchid, such as Quetzalcoatlus, in which case I would recommend the schleich figure as all of their figures of prehistoric animals are very inaccurate
Hearing all this (awesomeness) info on taxonomy and how dinosaurs are grouped..... I'd love to see Steven do an episode analyzing the Indominus Rex to figure out it's genetic makeup (what traits it resembles with what _actual_ dinos, and where it may not resemble an _actual_ dinosaur at all). I'd totally sit thru a video about that :-P
True that.
Just in time for my birthday, what a fantastic birthday!!!
A new dinosaurs are wrong! And it's even longer than the last one? YESSSS!
This makes me so happy! Thank you for putting so much effort into your videos.
Would love to hear one of you guys breakdown the dinosaurs of ark
Always overjoyed when these come out. We missionary your show to the majority of our patrons.
We were curious, do you have an idea of the what the next few videos will be covering? Not necessarily a schedule, but more the order of videos?
Nice. Just found the channel. Admittedly I only understood about 1/2 of what you said but I hope to keep learning. Never too late to start at age 44
Wow! The moment at 31:21 is so well presented and beautiful. Congratulation for that piece of art and science.
You guys are the first organisation I have committed to on Patreon before. You are doing great work, and this particular video series is my favorite on TH-cam. Keep it up, and can't wait to see your next video.
I would so love if you could do a primitive pterosaur or a water lizard i.e. ichthyosaur, plesiosaur, mosasaur. And, at your own pace, an episode on the BONE WARS
Only one of those reptiles is an actual water lizard, but I would like to see an episode on marine reptiles or primitive pterosaurs too!
where have you been? glad your back, have you thought about doing Psittacosaurus with all the recent discoveries?
Have I ever! Got a few other creatures lined up first, though...
I think it would be interesting if you looked at the physical model for _Psittcosaurus_ which was supposedly the most accurate dinosaur model ever created. I'd love to see you try and find an error in it.
cdn.sci-news.com/images/enlarge3/image_4197_1e-Psittacosaurus.jpg
So hyped ! Can't wait to see your next work, this one was amazing as always.
*You're
So happy I found this channel. Incredible vid
This is such a great series. I really appreciate the work that went into making the animation to show the corrections in the animal's anatomy.
I love your videos, they keep me sane!!!
So excited to see a new video on my feed! Thanks for all the great info (and fantastic visuals!)
yay!!! a new your dinosaurs are wrong!!!
i really love the work you put into this- keep it up!! :D
Glad to see that you're back, I love this show, I always learn so much from each episode.
This video was absolutely beautiful! I loved how detailed you got in the last 10-15 minutes of the video!
Fascinating. Just found this channel, and I love how this series doesn't dumb down or "popularize" cladistics, anatomy, or paleontology, and yet is still very accessible. And so many sources from 2010+! I have no doubt you've covered the recent study on feathers (lack thereof) in tyrannosaurs, but I'll have to get around to those videos.
We have not, but that's a good example of why I've tried to be careful to note where further evidence could overturn what I'm saying.
Steven Bellettini Thanks for the reply, I am absolutely addicted to this series. Forget the Tyrannosaur feathers; I am itching to see your response to the Baron et al paper completely rewriting dinosaur cladistics! I think it comfortably merits its own video
I love this series so much. Theres so much effort in every way. I learn so much. Thank you tons and tons ❤️
I take a mental snapshot of the finished accurate animal. Who else does the same?
Jeffrey Gao I took a screenshot of all the finished dinos on this show and I try to draw them accurately based on his finished picture.
Maybe the best episode yet, very well done.
I saw this a long time ago, but I only just now thought to comment this:
Thanks a lot for this video. Not only is this one of my favorite critters, but this video seriously helped me out with a story I started writing with all of the info. I was modeling a sci-fi race in part around Archaeopteryx (because I thought it could be really cool), and being able to describe it in more scientific terms feels really good (as someone who is just an enthusiast/fan of science and not an actually scientist). Also, having the kind of environment to put them in was great for defining their planet (at least the part where they are located).
Sorry for the rambling there. I just love everything I've learned from your series, and I get excited learning things I can also use in my other hobbies. Love y'all. You're doing good work. :}
You guys make my favorite dinosaur/etc videos. I always learn something! (sometimes a lot of things!) So glad when there's a new YDAW!
That intro never gets old!
Absolutely amazing episode, once again. Love your series. You guys are phenomenal.
Really good episode, thank you! I appreciate the explanation of phylogenetics and taxa grouping done with good clear visuals, as it's something I never quite understood even though I was familiar with the concept.
I want to study on my own until 25:50 onwards is understandable to me enough where I could explain that on my own. I get lost pretty frequently and look up a lot of the words he uses and am slowly learning more. It's honestly so hard not to get completely enamored listening to people talk about things they know and love especially when the vastness of their understanding of the subject is so far beyond your grasp you need to decipher what they're saying to understand them. This is probably really stupid but I think I finally realize why the vocab is so important before the next chapter of a text book...
This is a wonderful description of Archaeopteryx Lithographica and Siemensii! Archaeopteryx is the main reason why I'm into dinosaurs, birds, evolution, and prehistoric animals in the first place! And to see it analysis very well here with new facts, just makes me happy! Keep up the good work, TheGeekGroup!
This is one of your best episode! I learnt so much! Thanks.
It might be interesting to take a Godzilla toy, and compare it to the real life Gojirasaurus.
I'd love to see Herrasaurus or Eoraptor. Would be a good time to talk about that 2017 study that dismantled Saurischia too.
This is awesome! Would giganotosaurus or carcharodontosaurus be good or that would have been covered in the allosaurus one
Why do i keep coming back to watch this episode every couple couple months?
Yes the archaeopteryx is my 2nd favourite animal (behind the thylacine) but there are hundreds of videos about this animal, so why THIS video?
The world may never know, but i'm glad it's here for me to enjoy.
Steven you are awesome. seriously cud listen you break down dinosaurs all day.....and I have. I look forward to this series more than any other on youtube!
You should really do the taco that would be so cool ( taco being psittacosaurus)
I've only recently started watching this series from the start (late discovery on my part) and I think this episode may very well be my favorite so far!
I love watching these videos! They really inspire me to draw dinosaurs more and I love trying to draw them in ways I’m not necessarily accustomed to :) did a quick lil sketch of an archaeopteryx 1/3-1/2 way through :)
Great video, really appreciated that information about traits, it was very informative and interesting applying it to specific topics within paleontology. I wish YDAW videos happened more often. =)
imagine how we would see dinosaurs if back then when archaeopteryx was found all the scientists agreed that birds are dinosaurs and non avien dinosaurs closely related to birds...
Hey, cool video! Really enjoyed and learned a lot about this little dinosaur! :) Also, I think it'd be cool if you could do a video on Acrocanthasaurus or Kosmoceratops.
I've been wondering where this show has been! Missed it so much!
Wish I could like a video more than once, this is one of my favorite TH-cam shows!
Any Latin speakers please confirm: is the 'p' in Archaeopteryx silent as in Pterodactyl or not?
Two years later: no, it's not!
great video, very informative, loved the animations!
I feel spoiled having only recently discovered this series and basically binged it the past week or so. Excited for whenever the next one comes out, however many months that may be :)
Can you do kaprosuchus
Pleasantly surprised to discover there are Kaprosuchus toys. Noted.
One of my fav crocodilians, along with Deinosuchus and Sarcosuchus.
YAY!! \o/ another YDAW!!
I'm still trying to find a Lioplueridon, not having much luck....
I would like to hear what you think about the Phylogeny Explorer Project.....
(btw, nice beard Steven....suits you well; well on your way to looking like a proper paleontologist. Now you need a shabby dusty fedora!...)
I just have to say I enjoy 'Your Dinosaurs Are Wrong' series but this episode was really interesting and educational. I enjoyed it thoroughly!
Always enjoy watching Steve
This was one of the first dinosaurs that got me really interested, since as someone who lives in the south of the UK i'd visit the London Natural History Museum a lot as a kid and growing up, i mean i still do now when i have the time to spend a day there when possible, and that Archaeopteryx fossil was always something i could just stand and stare at for ages.
The Natural History Museum was always good as a kid. It was also very early in reorganising it’s main display on the basis of cladistics (late 70’s if my memory is correct, but it might have been 81 or 82) so even growing up in the 70’s/80’s one of the takeaway messages was birds are dinosaurs.
Could you please review Gigantoraptor?
Or at least tell me if I am right to be bowel-looseningly frightened of it?
Also, what is that mokawked dinosaur in the intro?
Great question...
Maybe a really inaccurate corythosaurus idk
I Loved this series since 2014!!!
Please do Crylophosaurus!
Can you please do a YDAW on Mosasaurus? I know it is not a dinosaur, but it is one of my favorite Mesozoic creatures! If not Mosasurus , how about Paralititan? Either one would be great!
Ender Craft - Minecraft, Mods & More! I like Paralititans
He did Pteranodon, so Mosasaurus wouldn't be too far off
I've missed u :D You're amazing!
Awesome! A comeback!
I'd like to request a video on an azhdarchid of some sort, preferably Hatzegopteryx or Volgadraco, as I find this family of pterosaurs very interesting and I don't really see them featured... well... anywhere really. Quetzalcoatlus gets some time in the spotlight occasionally, but until Jurassic World: the Game came out, I didn't even know that the Alanqa existed. A video on anyone in the azhdarchid family would be greatly loved and appreciated.
FINALLY ITS BEEN SO LONG YES but can you do a video on *_Masiakasaurus Knopfleri_*
And you guys should make your own dinosaur toys which are accurate and show them at the end of the episode before the credits
Masiakasaurus is my second favorite dinosaur!
Great to see yet another awesome video from you guys - good job! ;)
There's one thing that really bugs me about cladistics, though - why is it that the basal forms of certain clades are always implied to lack any descendants? I mean, I'm willing to buy that birds didn't evolve from _Archaeopteryx_, for example, but something had to have existed at the same time as _Archaeopteryx_ that *did* evolve into birds - but what was it? Is the implication that only a select few _Archaeopteryx_ are ancestral to birds, and hence the rest of them hit a dead end? Because that's actually not a bad idea, in my opinion.
So yeah, if anyone's able to explain this all to me, feel free to let me know! :)
You're pretty much right. The options are adapt, move, or die out: some population of that common ancestor evolved into _Archaeopteryx_, and another population into whatever the next node is.
This is why I had to put '_hypothetical_ common ancestor' in the diagrams. It's just really statistically unlikely that one of the handful of dinosaur species we have record of was *the one* that went on to evolve into new forms.
Steven Bellettini
Oh yeah, I guess that makes sense, especially when you consider that only a handful of organisms fossilise, meaning there were probably millions of entire species out there that were never preserved in the fossil record. :( So Yeah, we can't just assume that any one organism is *the* ancestor, but rather a close relative of said ancestor.
By the way, thanks for replying! It's always exciting whenever a bigger TH-camr responds to me! :D
I love your videos!
Could you make one about the mosasaur or the giganotosaur?
Awesome presentation.
Just started watching this series and I love it
I've been really obsessed with learning about dinos recently.... its like I'm channeling my 10 year old self
One animal that will hopefully be covered eventually is some sort of Oviraptorid, probably Oviraptor as it would make a much more interesting episode than Citipati, but since they're considered very similar I suppose it would be appropriate to mention Citipati and Gigantoraptor.
I've seen several requests so far for Quetalcoatlus, which I definitely agree with if only to illustrate key differences between Azdharchids (which also include animals such as Hatzegopteryx and Eurazdharhco) and other Pterosaurs such as Pteranodon, Eudimorphodon and Pterodactylus.
I myself would be surprised and pleased if you were sent a model of Becklespinax altispinax, since I did play Fossil Fighters as a child and became familiar with the animal.
Great video as always dude
Could u guys do Gallimimus Bullatus, It has always been my favourite Dinosaur (ever since I was little) but I don't know how accurate the depictions are D:
PS: I love this channel, Keep up the good work, always excited to see another YDAW!
Yes, it's been a long time coming!!!
