Has it been decided what the next dinosaur the show is going to feature? Based on the comments I've seen it appears to either be Ceratosaurus or Quetzocoatlus(even though Quetzocoatlus is a pterosaur). I think Megalosaurus should be on the show.
thegeekgroup I want you to make episode about the Jurassic Giant Predator" Torvosaurus"
Thnx
Wow, that's really rude. Complaining about something you get for free.
T. Rex: "I have the smallest arm to body size ratio."
Carnotaurus: *"Hold my beer, because I can't."*
Cough cough underrated cough cough
awesome
lol thats so funny

Underrated
carnatorus never skipped leg day but always skipped arm day
Light weight, baby!
Leg day is more important than arm day. Carnotaurus has thighs that save lives.
Who needs arm day when you can just have neck day instead?
Scientists suggest that Carnotaurus could squeeze its prey to death with its thighs.
HolyFurryFish1998 Sounds about right.
It's so weird, from a human's perspective, to think that _arms_ of all things could be vestigial. That they could literally be useless when they've been so crucial for our success and greatness.
Amanda Egeskov Hald Use your mouth
Amanda Egeskov Hald that’s why they are dead and we aren’t ! ;)
Think about us and tails.
for dolphins, rats, birds, dinosaurs, cats and more. They are a must. But we do fine without them.
Even tho it would be interesting.
Kiwi and emu have vestigial forelimbs also
well.. we were depending on them, without our arms the world would probably still be a normal natural place, instead of this toxic waste..
Oh God I just remembered I called this thing the "horny rex" when I was younger.
Probably because the Disney Carnotaurus DOES look blatantly like Tyrannosaurus.
Not wrong 🤤
I always found that the weirdest thing about Carnotaurus's arms was that it didn't have elbows, in fact it didn't have a radius or ulna at all, it appears to have just had a humerus with assorted hand bones on the end. Either the other arm bones and the joint just fused together or they disappeared entirely I'm not sure. But the whole thing is made weirder by having them attached to a scapula proportionally bigger than other dinos with much bigger arms.
Just odd.
The scaps were there for the neck, lats and pec muscles. Abelisaurs were tremendously muscular creatures.
I study palaeontology as a student and next month we are covering Abelisaurid arm morphologies. I have written a quick summary on Majungasaurus Crenatissimus and it is similar to what you state
Less arm muscles required leaves more room for others, so the arms just slowly shrunk
@Sean Closson nice profile picture is that a nanuqsaurus?
Thalidomide apparently older than we thought?😉😅
Hi, thank you so much for using my toy!!! It was well worth the wait as you did guys did a fantastic job, as always. I'm glad I was able to contribute in a small way to this tremendous channel!!! Well done, well done. Also I apologize for being impatient earlier :/
P.S. Your updated/corrected sketch of Carnotaurus is my new desktop photo!
:D Glad you liked it!
+Steven Bellettini Don't you give the toys back?
Yeah I already got it back, perfect condition
Hey Henry, are you still around? If so, could you please let me know what brand that toy is? I really like it. Thank you.
Carnotaurus has been and will continue to be my favourite Dinosaur since I was like 3 years old it's just so fascinating
The Carnotaurus vestigial arms stored inside its body is a headcanon that I personally believe. Is it scientifically accurate? Probably not. But I like it and that's enough. It's just a mouth with legs.
"This.. _blunt instrument_ of a head."
I am no paleontologist...but I look at toy dino's all the time and think
"This is so wrong and innacurate"!
Ikr! I have an allosaurus from my childhood in my closet, and it is an abomination. It is green, scaly, drags the tail, has no crests, and an almost dog like mouth.
I did a lot of reaserch and found out it does
I have a raptor thingy and the hands are pointing down not to the side and few other stuff
Toby 7557 Old reconstructions man, old reconstructions.
Not Carnotaurus
Carnotaurus has and will always be my favorite dinosaur.
The thing I like about this video is that, even though the figure is very close to accuracy (like you said, the most accurate you've gotten so far), you still manage to hit 20 minutes. It is a kind of great trade off, where you can either spend a lot of time 'fixing' a hilariously inaccurate toy (while also explaining a bit) or spend a lot of time explaining things about a very accurate toy. Can't wait for the next episode!
I know this isn't a very important detail, but I always prefer depictions of the carnotaurus with its arms tucked flush with its body, rather than sticking out like normal arms, because it feeds to the vestigial nature of them, and the fact that they had virtually no uses for their arms.
I love these drawings and animations. Perfectly visualize the point, look relatively simple and yet very good and compelling.
Those smiling Carnotaurus made my day :D
I had a McDonald’s happy meal toy, hand puppet, of the Carnotaurus from Disney’s Dinosaurs when I was super little and that thing terrified me. At the brave age of 5 I got to see a life (ish) sized statue in Orlando and I ran from it.
would be cool to see him do a break down of the Carnotaurs from the film Dinosaur since a lot of artistic liberty was taken with their design
I'm gonna send you guys a cryolophosaurus
Thanks! :)
Sounds cool!
+Jeffrey Gao yep!
+thegeekgroup I like the ending with the history of iguanodon reconstruction... Sad you deleted it. :c
Yay, Elvis dinosaur!
Mazzetta in 1998 which theorized inter-specific combat of the horns for predation. The paper claimed that due to the thickness of the skull and the neck, Canotaurus may have been able to use its skull as a battering ram and thus make it the first predator discovered to use these features as weapons. This is thanks to the thickness of the skull and the heavily muscled neck absorbing the shock of impact. Ramming prey would've stunned or killed smaller targets. In a way, this makes sense as a pursuit predator. If you look at a cheetah or a falcon, their main objective is to disable a target once it gets in range before finishing it off - cheetahs will often trip the leg of an antelope while falcons grab flying targets in dive bombs. Carnotaurus' style was unique, but was likely another skill in a long list of tactics seen in nature.
Modern science says _Carnotaurus_ couldn't hunt with its' horns for many reason: horns are too short, no predator had horns like _Carnotaurus_, and its' head is weaker than they look.
@animalman57 Actually, the horns would've been covered by a strong keratinous sheath. What size and length of these horns they would've been in real life is unknown. Now, I read the papers again and it turns out that the power is stored in the neck, whose vertebrae was large, thick, and heavily muscled - allowing this animal to absorb a large amount of force. The horns would've been able to distribute force. The head was also rather thick and covered with small osteoderms which would've helped keep its brain safe from collisions. In short, modern science involving combat use of the head shows that it was indeed possible for this animal to attack rivals AND prey.
Deadpool3E only issue is that it’s horns pointed upwards and to the side, making them basically useless as weapons. Also last I checked, modern research shows that it’s head wasn’t designed for high speed head smashing, it would break its skull and since it seemed suited for hunting smaller game(it shows adaptations in its jaw that seem to allow to unhinge its jaws somewhat and could likely use its top jaw like an axe like allosaurus) then it physically would’t be able to ram them at all.
The thing is, carnotaurus was adapted to hunting prey that was small to medium sized prey. The reason I bring this up is because of carnotaurus’ size. It seemed to around 3 metres tall and at most 9 metres long, why does this matter? Because I doubt it could swoop its head down while it’s running without falling over. It could maybe do that to medium sized prey, but that would still probably hurt the carno. It seems to be more likely that the horns were used for display, or slow pushing battles for males. They’d maybe slowly push each other during mating season until one male gives up.
James Athersmith maybe the horns were used to take out larger prey? It seems to be the most likely possibility if Carnataurus did use them for hunting.
Love it! Carnotaurus is an interesting creature, imo.
I'd love to see a critique of a Quetzalcoatlus toy sometime. Or perhaps a marine reptile, like Elasmosaurus!
cheetah of hell. Only on straight paths, though^^.
Bob and weave you'll be fine
Carnotaurus problems? Just walk around it bro.
I love the fact that you put citations in video! More Science channels should do this!
I always imagined Carnotaurus to use the horns over their eyes like Giraffes do to settle disputes; smacking each other with the sides of their heads.
what a cool channel!
Viral Killer definitely
I just realized, every animal and dinosaur do different things to thrive, it’s like they’re using different strategies for survival, carnotaurus “let’s try pure speed and nothing else”
T. Rex “bigger is better”
Humans “Knowledge is power”
And my personal favorite
Water bear “random resistances for no reason”
Tierzoo lol
Tardigrade is perfect organism.
I think it used it head as a stunning mechanism. What I mean by that is that it charges its prey, hits it with its head causing some damage and knocking the prey somewhat to the side, stunning it a bit, and then using its chance to start to bit the prey
isnt that a Papo sculpture? Would love to see you review their various dinosaurs. Beautiful sculpts with lots of details and nice paint jobs.
Completely inaccurate though
This is my new favorite channel for info on how to accurately draw dinosaurs, there's so much useful information here which i fully intend to utilize
Ay, kids aren't going to ask their mom for a dinosaur without arms, and they probably won't for one with sausage arms
I can just imagine Carno running next to a prey item and slamming one of it's horns sideways into it's preys neck or head, and tbh it probably could've done that because of the amount of muscle it had lol
Maybe not like a blade. I'd say maybe more like a bludgeon to knock its prey to the ground
I have this toy on my desk! This company makes some of the nicest dino toys. Even the ones that aren't that accurate are sculpted really well.
Whats crazy is The Isle (the game) really took the anatomy of the dinosaurs and applied it to their in game dinosaurs. For example, the part where he says the trade off with maneuverability and acceleration due to the structure of their tail muscle. The carnotaurus in game is the fastest dinosaur with the slowest turn radius in the game. I thought that was very cool
Brings back good memories of getting ambushed by Carnos and booking it to the forests to escape
You are one of the few people on TH-cam who posts the links to where they found the information, and for that I thank you.
OMG, I've found my people- dinosaur nerds!
SimplyEpicGaming
Yes you have, my friend!
GOD DAMN ALSO ME FAVORITE DINO!!!!
After spino.
My fav is utah-raptor and spinosaurus
Same
same
@@ItsARandomDragon i don't have a fav dinosaur I like all equally
when i play with my toy carno i always imagine it as headbutting the other toys
Ya same but I was a freak for accuracy like I would only play with Dino’s that would actually interact
Xd same
@@warasaurbuilds139 what dinos would interact if the time machine screwed up the timeline?
I think there was a documentary that speculated feathers on the nub-arms used for display. Unlikely, but cute.
I could listen to you talk about dinosaurs for hours. Somebody get this man into a university lecture hall! I'd love to take that class 🥺

SpaceTaco 101 oh hello the but i think you will never answer
I’VE JUST BEEN WITH THIS DINOSAUR (WALKING ON FOUR FEET) AND I KNOW IT’S A SPINOSAUR! I KNOW FROM YOU! PREHISTORIC HISTORY, NOW I’TS FACING ME...
Jack Armstrong what Dino? Carnotaurus? Is so it did not walk on four legs. It’s arms were too short.
@@jackarmstrong8790 I read this in the voice from the song and nearly choked while laughing so hard
Carnomi Fujiwasaurus
Speaking of Godzilla, I came across a Bag O' Dinosaurs containing a pretty accurate Godzilla in with the tail dagger dinosaurs.
I was right about to mention how accurate a toy on here was for once and you beat me to it 😂
Gorgosaurus is my favorite dino. I'd love to see him on this show. Wish I had a toy to send you though. I'll try to find one!
A new episode of YDAW? BEST DAY EVER!
I second that!!
YAY!!!! BionicleSaurus... YDAW??? This is my best day ever!
Please do another Dinosaur series like Dinosaur Island! I love ur channel Bioniclesaurus
omg you like this too i love your channel

It's just me guessing but I think their horns are used similar to how giraffe's use their ossicones.
Ossicones are skin covered club like weapons, and they use it by moving their neck in a whip like motion, swing the clubs to the target. Carnotaurus are probably doing the same thing
Instead of striking head on like how deers and moose do. Carnotaurus probably swing those horns. Maybe their goal is to sprint towards their prey, and as soon as they reach the head or the body of said prey, that's when they strike. And considering how sharp the horns are, it may not enter the body (which is better, you don't want your horns getting stuck in a running prey) but it probably can fracture bones, especially the rib cage, and cause trauma with the organs. Now that's freakin dope!
Kinda like a much faster, carnivorous sprinting Giraffe. Capable of swinging its head side to side while running.
As a french, when you speak of Bonaparte, I think to Napoléon, not to an archeologist XD
*paleontologist
*Paleontologist
Same thing I thought, though I am not french XD
Krankar Volund i to am a french
everyone does, even me, and im from the country next to argentina
Bonaparte is the Emperor of discovering dinosaurs!
I’m glad that carno is somewhat accurate, like I don’t need to rethink everything I know.
Carnotaurus: Armoured speed demon of the plains.
I've loved carnotaurus ever since I found out about it and it's one of my absolute favorite dinos. I just love the juxtaposition of its ferocious appearance and predatorial skill with its dinky little arms. (It always makes me sad when art or toys make the arms too big because that's what makes it so endearing to me)
The video game The Isle lets you play as a carnotaurus and I was actually super impressed by its accuracy considering the featherless rexes and raptors (though it definitely has the same problems with the foot scutes and possibly oversized calves the toy in the video does) And it's play style is exactly accurate to how you described it hunting, with amazing speed and stamina but an obnoxiously wide turn radius (which has the added effect of forcing the player to favor open terrain instead of forested areas just like the animal itself.)
I guess tl;dr is that I love carnotaurus and would recommend The Isle for other fans of this beautiful creature
Another great video!
Yeah, my biggest problems with this figure are the pose and the tail.
There needs to be a Secernosaur toy. Even the Field Museum keeps the holotype in storage even though there's a great mount at the Museo Argentino de Ciencias Naturalis Bernardo Rivadavia.
I like the thought of it attacking like a giraffe with it's big ol' head mace. Unfortunately, that seems like a waste of all that forward momentum, so perhaps more battle-axe. :P
carnotaurus is my favorite dinosaur
Thanks Man
Carnotaurus Ha ha good one
Your name is metriacanthosaurus nerd
You can tame one pretty easy in a game called ark that might excite you
Me too
18:51 And then they're one step closer to becoming Squigs! :D
What sucks is that all we know of the fauna of the Carnotaurus’s habitat is that “there were hadrosaurids” and “we found an ankylosaurid osteoderm” and that’s about it. We know there was another albelisaurid and a few other animals. I hope another expedition is done so we can get a better understanding of the other animals in the area.
There was also turtles, snakes, and other animals but I would like to know or see the more exact dinosaurian species in the area.
Wow, that's an amazing detailed little toy model. Great talk by Steve, thank you.
I love your videos on dinosaurs. You're super educated and informed about dinosaurs. Jurassic Park movies need you as it's consultant. I hope the Universal (the studio behind jurassic park movies) acknowledges your input on dinosaurs.
personally besides butting rivals and display i think its horns might have been used to mark territory by gouging notches in trees sort of like some species of deer do. also as for predation i could see them running parallel to there prey and swinging those horns into the legs of the prey to slow them down so it can get some strikes in with those jaws.
Akaryusan I Glinka if it did that, it might break the side of its head, or get trampled on
i can honestly say i love your vids. I am a soon to be paleontologist and everywhere i go i see the awful dinosaur toys out there. Often finding myself chuckling
Love your work! Keep up these amazing videos preaching people about, how Dinosaurs were.
moas and kiwis are actually the dinosaurs with the smallest forelimbs
You guys are amazing! Thanks for all your hard work!!
Thank you! :) We're glad you enjoy it!
I suggest getting the Rebor figure, named Crimson King. The only inaccuracies I can spot are the tail being too flexible and the width of the head. Perhaps you can spot more? Also, I was under the impression that Carnotaurus's fingers are fused together (which in the Rebor figure, they are not). I also doubt Carnotaurus had a blue tongue (which the Rebor figure does) but i guess we have no evidence to the contrary. Some extant reptiles today have blue tongues (such as the Blue Tongued Skink). The arms on the Rebor figure can rotate, which can allow you to place the arms either in an accurate or inaccurate position. The scales on Crimson King are deeply defined and the scutes are VERY defined and pointy. I wouldn't give it to a kid to play with. I also love the neck of the Rebor figure, which seems very accurate. He also comes with a crackled cooling lava base that doesn't represent the natural habitat of Carnotaurus but it accents him very well. Beware of possible warped legs, as Rebor seems not to put any packaging between the legs to prevent warping from being laid on its side for too long in its own packaging. The foam packaging they use, however, seem to be of rather high quality. I love Crimson King. I also reccomend watching Trey the Explainer's video about Carnotaurus.
If you think about it. Carnotaurus is an animal that has low mobility correct? When its pursuing prey wouldn't it probably be more effective for the animal to knock its prey to the ground and then make the kill to prevent its prey making sudden sharp turns? Perhaps it could have used its horns to simply aid in knocking small or medium sized prey to the ground
This is so helpful and entertaining to watch while drawing the dinosaur being talked about in the video.
Maybe the arms are only used during mating to stop the male slipping off, and claws to stop the female running away
I don't think they could move their elbows, though. So they weren't able to use their arms for anything.
Carnotaurus' arm sockets were ball-jointed and had an absurd rotation range compared to pretty much every other theropod. Clamping down on a partner would be more than possible.
Then what are the females using their arms for?
Jeffrey Gao Sexual dimorphism can only go so far. Men have nipples, but never use them.
A dolphin named Infernicus I have nipples. Could you milk me?
I only watch these videos because the animations are so satisfying.
YES!
Favorite Dino, baby!
Been waiting SO LONG for this! :D
Thanks Man
TVJUNK85 I KNOW
TVJUNK85 favorite dino huh why do you jave a cerato profile traitor just kidding
Awesome vid! Carnotaurus is a favorite of mine. Never encountered the idea of encasing the arms completely inside the body a la whale legs.
Everybody gangsta until the carnotaurus start runnin
Yes! I've been waiting for another episode from this series 😀
the neck muscle build in combo with the leg/tail build suggests that the carnotaurus did a lot of high speed shunting, as if to topple larger dinosaurs to expose their underbelly? the neck muscles are built for impact and leverage it seems and the more momentum you can slam into something the easier it is to topple. and looking at most of the herbivorous dinos it seems like getting up from laying on your side was a very vulnerable position to be in, it would also help the carno to avoid all the defences that other dinosaurs like the stego and kentosaurus had built up
That is a pretty DAPPER Dino you've got there!
This is the first of the videos I've seen by NSI, but I have to say I am amazed at this young man's depth of knowledge and obvious passion for his field.
IMHO, he should design and collaborate with some artists to put out a scientifically-accurate set of dinosaurs.
I would buy it. I would sell my good kidney to buy it.
Thank you!
Edit: My son just said, "Carnotaurus skipped 'Arm Day' (lifetime)." I'm dying.
I love this series!
OOOOW maybe that's why htey have such tiny arms... They literally lie down on the ground for an ambush and the arms help them adjust position before jumping up at their pray. Maybe like a crocodile but hiding in tall grass rather than water?!
great video as always...really love this series...and for once i actually learned alot in this installment....thanks as always for your super informative videos..may i suggest a species of plesiosaur for a future installment...yeah i know...technically not a "dinosaur"...would love to see your take on one anyway..
That was a very neat magic trick
I have that carno. Its really beautiful
Please do Dilophosaurus next!!!! :D
It's an oldie, but a goody! th-cam.com/video/28NbtPqHPI0/w-d-xo.html
+thegeekgroup can you do allosaurus please
He already did that
+thegeekgroup giganotosaurus
thegeekgroup Thanks!!! I guess I missed it when I was looking through their videos!
the visuals give me perspective as an artist, thank you!
I think the horns may be to small to ram effectively but used it in pursuit to disbalance the prey and a way to trip or cause it to stumble to help finish the prey off and stop the chase to a finish
yes! new episode!!! I love thys series and steve!!!!
The animation at 14:30 is pure comedy gold!
IM addicted to this channel
Something in my brain snapped when you made the head narrower
So.... Carnotaurus may potentially have headbutted prey that was almost as large if not even larger than himself into submission? That's kinda weird...
Bless TH-cam suggestions, kinda bummed I forgot to check for new episodes.
2:56 I guess it's closer to Albertosaurus, Hypacrosaurus, Tarbosaurus and Deinocheirus in age then ;)
carnotaurus be like: legs legs what's on the menu legs legs what's on the menu? legs!
with such a short mouth i would imagine it would be fairly difficult to grab hold of a running creature with a bite (which with its lack of grabbing arms it would need)
however with the fact its clearly a sprinter, its huge neck muscles and the large horns, could it have predated by effectivly charging its prey, slaming its horns into the side of back of the prey animal injuring it or knocking it down, and then biting onto it while its down?
"Running theme." Haha, get it, because Carnotaurus ran after prey- nevermind.
This is fascinating. Subbed and binge watching!!!
Ah, yes, the eternal Naruto runner.
I've waited for like ever for this!
17:52 carnotaurus is giving you a thumbs up
Carnotaurus: smallest arms for it's size but largest running muscles for it's size
He said something about Dinosaur arms that isn't true, Carnotaurus does not posses the smallest proportional arms of any dinosaur, that award goes to Mononykus.
Yay new episode!!! Steven do you have any thoughts on the theory that the arms could have been used for display? or were they pretty much non functional nubbins on their way out?
I have a theory here. Perhaps those huge, head-aiming neck muscles could have allowed carnotaurus to whip its head sideways like how giraffes fight. Why it would do that, I have no idea, but...
Been waiting so long for this
Love your content. Keep it up!
