From end to end, its forelimbs alone measured an incredible 2.4 meters long and were tipped with big, comma-shaped claws. But other than its bizarre arms, very little material from this dinosaur had been found: no skull, no feet, almost nothing that could give experts a fuller picture of what this dinosaur actually was.

When I was 6, I read in Polish children's book about dinosaurs that Polish archeologists had found Deinocheirus's arms in Mongolia. At the time to me it was a great puzzle that wasn't likely to be solved. As years went by, I forgot about this, right until you posted this vid and it brought lil bit of childhood memories. Thank you Eons.
Oh, wow, that must be an incredible feeling. Thank you for sharing, it made me smile.
There’s a documentary on Curiosity Stream, called Amazing Dinosaur World. It shows this Dino and it has great cgi. I recommend!
Same here :)
Krzysztof Rolbiecki I remember reading a book about it when I was young as well, and it was fascinating to wonder what it could have looked like.
I read about as a kid as well. It was thought then that they belonged to a gigantic carnivore. I used to imagine how big it must’ve been. The reality turned out to be quite different, haha.
The poor guy was tired of being told "grow a spine" by his father, so one day he just freaking did. The rest is paleontology.

Comments like yours give me hope for TH-cam.
Imagine if Deinocheirus didnt have an actual body and was just a floating head
I thought the arms could make a neat ghost pokemon.
Just floating arms. They can wave and give high five.
Guys it's haunter

You're a carnivore walking around and then all of a sudden 2 giant arms start floating towards you

My father took part in those Mongolian expeditions with prof. Zofia Kielan-Jaworowska. I always love to hear his stories about them. He is still active in the field. Some specimens found on these expeditions are now in the Warsaw Evolution Museum.
Cap
The hump was bred there by ancient cave men so that they could attach a saddle and Fred Flintstone could ride it to work.
I admit this was my first thought too. Totally the right spot for a saddle and it would of been a hell of a ride!
Omg yas XD
Oorr...
It had a survival-related purpose , such as fat-storage or weight-balance .
Now considering that geese etc. , don't need arms to feed on vegetation , it stands to reason that they served a different purpose . The obvious one is for catching fish , with defending itself also being credible .
Lastly , the pygostyle . This tail-feather support-structure would have given Deinocheirus' tail the appearance of a branch with a smattering of leaves upon it . Logically , Deino. was camouflaged in order to deceive fish , and attract them to it's shadow . It follows then that the dinosaur had rough-looking, dark-colored plumage . This to appear like a mostly-dead tree trunk .
*To compare Deinocheirus to it's fully carnivorous counterpart Spinosaurus , read my post at :

You must have taken a trip to the creation museum in Kentucky
When you look at its bones it looks like a demon dinosaur sent from hell, then when you see how it actually looks with all its flesh and fur you realise it just looks like a cute oversized bird lol
Anything can look like a demon if you look at the bones only
looks like it's from Sesame Street Fight Club Edition
You know that's almost certainly not what it looked like. I mean sure they are educated guess but there still just guessing.
It's fascinating how popular depictions and scientific understandings of what dinosaurs looked and acted like have shifted over time. Back when we assumed they were all cold-blooded and similar to modern large reptiles, we thought of them as big, dumb, slow creatures. Then we realized they weren't all exotherms and that our assumptions about their metabolic rates and activity levels were misguided, and that Land Before Time-esque image of giant herbivores standing around like statues or slowly plodding along gave way to Jurassic Park's terrifying murder lizards, with those seemingly docile herbivores also being seen in a new light since they had to be able to either outrun or outfight those vicious apex predators. And with the revelation of proto-feathers / "dino fuzz" and an ever expanding knowledge of the rich biodiversity of mesozoic life, the range of popular perceptions about what a dinosaur can look and act like is also expanding, particularly to include more bird-like features and body plans. I wonder what our depictions of dinosaurs will look like in another 20 or 30 years.
*Bird fur* ?
Everybody gangsta till Deinocheirus flexes his claws
Or her.
But even he has to feel a little jeally when Therizinosaurus shows up to the party. :)

This is hilarious
Sounds like my teacher.
I saw the lecture from Phillip Currie in Edmonton where he broke the news of the solution to the mystery. I went in excited, but I came back out nearly in tears and angry at the fossil poachers.
EDIT -- That's his photo at 5:10 and himself at 6:38 . He's basically the head of the team of un-named scientists the video keeps alluding to, who assembled the clues and revealed the finds. He's a scientist from the University of Alberta (which is in Edmonton, Canada.)
Ah, I love Deinocheirus. It went from being the most mysterious dinosaur ever to one of the most well known. We now know every bizarre feature of its body (the tail-feather fan, the spoonbill, the hump) and its diet. Goes to show how one must never give up and that even the most baffling mysteries can be solved if you try hard enough, even if it takes years.
One can only wish it becomes famous like the T. Rex.
@@siyacer Well, it's not as famous to the general public as Tyrannosaurus, but it's still pretty famous among paleontologists and dinosaur fans.
Deinocheirus is one of my favorite dinosaurs just because of how strange and mysterious it is.
So a Therezinosaurus?
I like the Therizinosaurs. They're weird.
Ahh, Deinocheirus. I remember being a dino obsessed kid back in the day when all we had were these arms, and everyone thought it and Therizinosaurus were these huge, vicious predators.
Let's all have a laugh.
I remember those two mentioned in the book Dinosaurs: A Global View by Sylvia and Stephen Czerkas back in 1996. Yeah at the time only the arms were known and they were drawn side by side for comparison. Fast forward to 2020 and now we know so much more about that.
I remembered them too! It's so awesome to see how things progress.
I still wouldn't want to fight one, herbivorous or not
Me too, from a 90s book about dinosaurs
@@unexpected2475 Just like Hippos they may eat plants but you don't want to mess with hippos same for Elephants rhinos bison etc. "Herbivore" definitely doesn't necessarily mean passive or peaceful
I used to see those huge arms in the Natural History Museum in London all the time as a child, and I'd wonder at the great beast that originally owned them. I am so pleased to know this mystery has been solved, even if it isn't the super-mega-ultra-death t-rex my childish mind imagined.
Nope just a big ol duck.
It's weird how the "trader" and the "poacher" are treated differently. They're basically in business together.
one pays for a license and a degree. the other is a trader XD
I think it’s because the traders are needed to get fossils from the poachers to actual paleontologists, since poachers don’t do business with paleontologists directly
@@zohabaig6426 traders aren’t the only source of archeologist let alone the favoured source for them. Poached fossils get sold to private collectors, when those aren’t interested, traders turn to scientists
@@mmcat2863 no what I meant is, if a fossil is taken by a poacher, the only way for it to find its way to a paleontologist is a trader. I’m sure paleontologists don’t prefer to trade with them!
Depends on the individual. In this case it seems like the Trader in question didn't have any idea these bones were stolen decades earlier.
I know this probably almost never gets said, but I really appreciate how your editors never show a purely static image. You may show pictures taken of fossils, or an artists interpretation, but there's always some kind of motion or effect applied to the image and it's very nice.
Literally the first image is static lmao

Bear Mro I could totally see that actually! A Titanic-esque movie about the journey the skeleton went through from being discovered and scavenged, to pinballing all over the world in fragments, to the toe being returned and skeleton reunited! Once the whole picture (IE skeleton) is complete, the movie ends with a short flick about the life of Deinocheirus, possibly ending with an artistic interpretation of that specific specimen’s death. I dunno about you, but I would watch a movie/documentary like that!
Imagine how the Dino feels about it 😂

And now deinocheirus is finally in a documentary, prehistoric planet
it is so satisfying watching it scratch its side
"Like a dinosaur cinderella" omg I love you!
Deinocheirus: my favorite dino-mystery! It was featured so prominently in many of my childhood dinosaur books, at a time when we only had its forelimbs.
This creature gave a new meaning to the phrase, "well-armed."
This is probably one of the most fascinating episodes yet, I loved this!
Well gastroliths are incredible! Amazing to think of birds (and these dinos) chowing down on rocks!
It always blows my mind that these creatures existed at some point in time. Amazing!
Acapulco Gold Pablo Picturing these things walking around, and moving gives me the chills. I don’t think they would have looked so scary though. Just like big birds, but that doesn’t mean I don’t think they would obliterate me in five seconds.
I remember all of the old out dated depictions of this giant in my dinosaur books growing up, from mega super predator to plus sized therizinosaur and finally to the biggest and strangest ornithomimosaur of them..well at least so far anyway
I figured the sail would've been for large muscle attachments for those large arms
I would love it if Eons would make a video about the science of fossils... how they form, why certain bones get lost, and who even owns a newly discovered specimen?
Gotta love Steve for supporting so much this show
* supporting this show so much
Abstract: Large features tend to be resource expensive. It seems unlikely that the sail feature didn't evolve as a single solution to multiple selection pressures.
Hypothesis:
A large mass on its back would raise its center of mass but would also add an inertial counterweight to its stride. Each leg would have a stabilizing load that could increase the efficiency of its range of motion in forward motion,.
Fat storage would provide buoyancy, but whereas belly fat and hip and thigh pads would provide lower center of mass and better agility in a terrestrial environment, having a flotation device under you would tend to flip you over... Where having the same buoyancy above your center of mass, would tend to keep you upright.
It may also have served to increase the keel area of the dinoceirus while swimming, improving paddling efficiency.
It evidently lived in an environment that would have exposed it to both the risks and benefits of a semi-aquatic life.
It is most probable then that the sail feature evolved as a best-compromise between the almost mutually contradictory selection pressures of terrestrial and aquatic environments with presence, size and location of the sail serving different advantageous functions for each.
And when you already have sail, why not make it fancy during mating season.
@Craig Carmichael counterpoint: bison, dimetrodon, edaphosaurus
Which it then could have used to intimidate predators and attract mates
I really like her, her voice is gentle and nice to listen to ^^
I'm curious about the sail. It's interesting that the Spinosaurids, Deinocheirus, and some Hadrosaurs shared humped/sail backs. Is it possible it's an adaptation related to their semi-aquatic lifestyles?
Just passing through to give my thanks to Steve
Yup, this guy really appreciate the opportunity to help keep the show going!

I love love love that Eons acknowledges all the social and cultural influences and events that go into teaching about one dino. It makes for such better, more enthralling videos, and helps demystify so much that goes into how history is told & who tells it.
First of all, I just want to say I love watching Eons, Great job team. 2:35 Correct me if I am wrong, isn't it the other way around? "The left arm is missing the claws and the right arm is fully complete"
Unless someone flipped the image, or if for some bizarre reason it was originally a mirror image, yes. That threw me for a long time, too.
My guess about the sail: it would have made Deinocheirus look even bigger from the side, which would have been good for intimidating predators. Its claws and long arms would be useful for defense as it would otherwise be very vulnerable.
I saw those arms at the New York Natiral History Museum and I was awe-struck
This is amazing. I had no idea this mystery had been solved.
Before even clicking the thumbnail, I knew it was Deinocheirus.
The thing's absolutely insane.
Deinocheirus was a weirdo for sure. Thank you Eons for bringing us the fossil discovery back story of this fantastic creature. This episode was brilliant!
It probably survived longer than humans ever will. And there were lots of dinosaurs that looked like it too. Actually, as of now, humans and elephants are actually some of the weirdest animals because it's the only surviving member of its family
Some people say that the sails on spinosaurs were for making a shadow to attract fish like modern day birds do with their wings.
I didn't know that. How interesting
Could you elaborate on why this would attract fish? If anything I would believe that a shadow scares away fish as they would think it belongs to a predator above the water (?)
@@CroissantFromarsch curiosity
@@CroissantFromarsch I believe what he is alluding to with this theory is a hunting strategy some wading birds (like herons) use called tent-fishing. The point is for the shadow of the wings to not only reduce sun glare, but fool the fish into thinking the shade is a safe place to hide.
yo thats cool asf thanks
I remember when I was like 12 or so I had this book called something like “Dinosaur record breakers”. It repped all the biggest, fastest, ‘scariest’, most famous, etc. rendered in terrible 3D, and I remember one of the records was ‘most mysterious’. That one was held by Deinocheirus, which was represented as a giant dromaeosaurid-looking carnivore. I think the modern understanding of Deinocheirus is much cooler.
Same! I still have that book with me! It basically looks like an oversized, naked Gallimimus, lol!
We had a set of encyclopedia published in the very late 80's about dinosaurs that I would read as a kid and this one always fascinated me because all we knew of it was it's hands and it was speculated, in those books, to be a terrifying predator that was bigger then T-Rex. So finding this out is really neat.
Just arms fossil: Deinocheirus
Surprisingly perfectly matching bones from two different sources:
Deino-CHEER-UPS
Woah when I was in middle school many years ago I got a huge encyclopedia of all known dinosaurs at the time and I remember Deniocheirus very well as I was fascinated by what the creature looked like that we only had the arms of. I never heard this story and it’s really cool to see what it looked like now
@EonsShow I was wondering if it would be possible to do an episode on the difference between avian and non-avian dinosaurs. Are we talking the Aves and the Aves-nots or what? Ahahaha, leave me alone it was 3 in the morning. You have skimmed this subject many times, but it would be cool to learn what really are the things that define each, and where/when they split, etc..
I’ve wondered about those hands my whole life. Thanks for finally answering that question
The sail is used to swim through space. Dinosaurs never went extinct, they just left the planet during the beginning of the ice age to find food.
Lololol
some one already did it in the 80's lol th-cam.com/video/gy7fO2i9y94/w-d-xo.html
Facts
Nah... !
It's similar to the way camel humps function ; it provided much needed water and nutrition during the seasonal hard times , and insulation against the extreme heat and cold the dinosaur was exposed to in that temperate-zone flood-plain environment .
It may also have been a supporting structure for a muscle-set which Deinocheirus used to sweep it's head through the water constantly , ingesting both plants and fish as it did so .

Really interesting video! I just really enjoy it when a mystery like this, given time and the effort of dedicated scientists, leads to an answer. It’s really a testament to the hard work that paleontologists put into solving the many puzzles that are left behind by fossils. We live in an amazing age of discovery! Thanks to EONS for helping to share and educate the world in a way that we all can understand. Really great stuff!
I love this channel, it is very educational and I love learning on this channel ♥️
Ornithomimus means bird mimic! Struthiomimus means Ostrich mimic.
Exactly! Also, judging by the number of comments confused by the word "mimic" in relation to which animal came first, it would be better to translate it to "bird-like".
Gallimimus means chicken mimic
Man, I love this channel more than my life.
It feels so basic, but I can never get over the scale of everything back then. Our scale is so, so small in comparison!
Completely agree! But I also forget how HUGE Africa Elephants are too! I've only ever seen one from afar in a (very well run) zoo, but even at a distance you could tell they were bohemoths!
Yeah but we're still giant compared to 99% of known life, so it's not that weird that stuff is occasionally bigger than us
Now all my dinosaur encyclopedias from when I was little are obsolete lmao, bruh moment for the those who thought of it as some massive Therizinasaurid or Maniraptor
Yeah, same. I have that famous dinosaur book with the Luis Rey artwork, and in it Deinocherus is basically censored and they only show its claws and feet. At least they correctly classed it as an Ornithomimid. Also, many, many more dinosaur books are now obsolete for another different reason. RIP Troodon. F*ck Stenonychosaurus.
That's... pretty close for a guess actually...
I collected all those DK dinosaur books back in the 90s. I used to read them like it was a Pokedex. Lol
Cintrón Productions wow, troodon being defunct is news to me! I remember reading as a kid that troodon might have been one of the most intelligent dinosaurs. Thanks, for getting me up to date!
Cintrón Productions What Troodon??? What happened? I never heard this? So Troodon didn’t exist? Damn used to love that creature
I'm so grateful I lived to see this
I think it depends on the "sail". Some might be anchor points for big muscles, others for fat deposits, others for display... Don't fossils sometimes reveal that, like signs of ligament attachment?
It's hard to grasp that something like this ever lived, wow.
Thank you for letting me know this,You guys are awesome!
i wonder if some future species will do something like this for humans
"And we determined that these bones are human because of the fossilized Nokia phone we found nearby." - Future Species Paleontologists probably

This was extremely fascinating to watch. Keep up the amazing work 🐔 💓
Deinocheius is my favourite dino,and watching videos about him makes my heart feel warm
Next video should be on the biggest mystery in the PBS Eons world: who is Steve???
Yesss, my favo dinosaur!!! I think those extending "spines" on the hip where for a hump, since bisons have proportionally the same length of "spines" on their back, and tbey dont have a sail. It is also the plave where the hump is, its above the hip. So thats why i think it rather was a humb than a sail
Finally, after wondering for years (since I was a kid), now I know what a Deinocheirus looks like. The dinosaur cards collection I had before only have the illustration of a pair of claws. This video explains a lot info to me. Thanks PBS Eons...
Thank you so so much!!! I love dinosaurs and finding your channel was amazing.
I liked this episode, solving scientific cold cases gets me every time
Talk about the *Giant Crinoid Rafts of Holzmaden* !
PD: Awesome video
This!
I remember seeing just the arms being shone in dinosaur books when I was a kid and thinking it must have been a terrifying predator. It's certainly not what I expected it to look like.
Nice! I remember reading about this one as a kid when it was still poorly known
i think they used the sail to be cool. it works, as they are my favorite dinosaur
Love this episode; Deinocheirus is my second favorite dinosaur!
Eastern dinos are very different than their western cousins. Wonder what they will find next.
Wow I remember being a kid and always learning about those arms. I can look back in old dinosaur books of mine now and see how different it was drawn, when we only knew the arms!
I learned something. Previously to this video I thought Deinocheirus was a Therizinosaur, not an Ornithomimidae. Thanks for clearing up this mistaken idea I had!
When I was a kid, I pictured deinochirus being like a giant dromeosaur and shivered. Now I can just snicker at the poor thing.
On the plus side, it has the perfect face to make sock puppets out of.
Poor thing? It was a badass surviving in the midst of tarbosaurs! I think it looks exotic, original and dangerous.
I remember just walking around on Ark, turning around and seeing one of these charging at me, I almost died, in real life.
I think the sail on the backs of many of these dinosaurs was to allow such large animals to keep their shape properly without straining themselves too much, being so large there is a lot of weight falling forward when walking on two legs, having such a large back kept these animals healthy by allowing for more muscle to anchor to the bones.
This was such a fun watch!
I think you got the left and right between the picture and the arm/hand location on the creature mixed up.
It's right arm looks like it has claws and it's left doesn't.
Perhaps they flipped the photo.
@@pansepot1490 hummm... It's possible but that means the person who did the photo/video editing should have spotted it.
It's only a minor annoyance but something I felt the need to point out.
@@pansepot1490 I thought they must have flipped the photo too. I think they add pictures after writing the episode so it's more probable that the error is in the picture.
I think the sail may have helped it swim better or gain buoyancy. It could’ve been a semi-aquatic dinosaur, and the hand/claws would’ve helped it reach the riverbed easier. The feet being squared off could suggest it was a strong paddler
Very informative video! Deinocheirus was such an cool dinosaur!
Very interesting. Thank you!
