I love the all yesterdays Therizinosaurus depiction. They had it heavily feathered, so that with its more upright stance, they seemed almost robed in black feathers, and they had given them a long prehensile tongue and that them stretching their heads and tongues up to feed on leaves. Stretching entirely with the neck instead of the theory some people had about its claws being used to pull branches.
Something I like to imagin the Therizinosaurus using its claws for was marking territory. If you look at lions, bears and other large predatory animals, they do this. I could see this animal using its claws for marking ones feeding grounds.
+Homer the Triceratops Surely you've seen hippopotamuses flicking dung about with their tails, or rhinoceroses practically hosing down areas with their urine, to mark their territories?
I don’t think it’s enough justification for those giant claws, but it’s certainly a possibility, just more of a cherry-on-top thing than anything else.

So, when you have a 2 year old steadily getting new dinos, and mastering their names and identifying them.....it behooves the parent to check out this guy ☝️who will let you know how to pronounce Therizinosaurus, as well as classify it with Therapods and maniraptors.....so the baby doesn't keep calling it a velociraptor when it's clearly not
Therizinosaur is what happens when T-rex's vegan cousin has had enough of its $#!t and was all "Oh yeah! well do you even lift bro?!" and so grew massive clawed arms to dunk on T-rex's mini ones.
I was always under the impression that Therizinosaurus had sloth-like claws without a sharp edge that used them to pull down high branches. It does make more sense that they weren't used for this because they have such a long neck. I always thought that the claws couldn't have reasonably been used for defense as they appear too big for this purpose, but now that I realize they weren't for the previously mentioned purpose, this seems to be the case. Maybe they really did use them like scythes to cut plant matter for food? maybe they used them for opening certain seeds? Therizinosaurus seems to be one of the most ambiguous dinosaurs as they defy the given laws for theropods (carnivorous, horizontal posture). I still feel like I don't quite understand this animal. I feel that there simply must be more that we have yet to learn about this animal. Thank you for displaying everything we currently know about this creature.
Agreed. I can't wait until we can get Bellettini-corrected dinosaur merchandise to go with it! (yes I know the 3D-printed ones are available on thegeekgroup.org, but I want full injection-molded-and-colored ones.)
Maybe, like sloths, it used those claws to climb up trees and it's posture could have allowed it to perhaps more comfortably climb up trees. I can't really imagine it climbing incredibly high, but maybe thats why it had a long neck, to reach good leaves while in trees. However I could be wayy off. Just a thought I had in mind.
This seems like it might be a really cool angle for generational (life stage?) niche partitioning, like baby Komodo dragons being arboreal until they grow too heavy. Little therizinosaurs clambering around in the branches with their baby claws.
Paleontologists: Okay so we've determined that all therapods held their bodies with the spines horizontally. Therizinosaurus: I'm gonna pull a sneaky on ya
Therizinosaurus: So, in about 66 million years, there is going to be this guy named Steve, and he is going to take dinosaur toys, and mention the posture is that the hip for theropods should be parallel to the ground, I'm going to change that Tarbosaurus, T-Rex, Allosaurus, Deinonychus, Velociraptor, Albertosaurus, and every other theropod: How? Therizinosaurus: My hip is going to be like a tripodal dinosaur toy. Tarbosaurus, T-Rex, Allosaurus, Deinonychus, Velociraptor, Albertosaurus, and every other theropod: BRILLIANT!!! *66 Million Years Later Safari limited gets it right/wrong, Steve is kind of surprised Fossilized Therizinosaurus, Tarbosaurus, T-Rex, Allosaurus, Deinonychus, Velociraptor, Albertosaurus, and every other theropod: Awwwwww.....
This is one of those creatures that you’d more expect to see on some distant world or another dimension. It looks so alien to anything we’ve come to understand about life.
These videos are amazing. I'm on a binge right now. Please do nodosaurus so you can talk about that unbelievable fossil that was unearthed a few years ago.
The case of Therizinosaurus and Deinocheirus as (probably) obligate herbivores descended from a very carnivore-aligned group is a very nice example of evolution. As the late cretaceous Mongolia lacked the large ceratopsians and titanosaurs that roamed Laramidia, Maniraptoriformes evolved into the now vacant niches. I wonder what differentiated the niche of Hadrosaurs from the ones the other local megaherbivores, as those can be found as very massive forms (Shantungosaurus in Asia, Edmontosaurus in NA) in both habitats. Has anyone done research on that matter? On an unrelated note, the feathers on the model connect to the third finger, while the arm feathers on theropods connect to the second finger.
I was thinking while watching this one about how to make a balanced bipedal theropod dinosaur toy and I thought about having a hollow within the tail and body of varying thickness to make the weights of each balance across the hip so that the toy would balance correctly. Not sure I'm conveying my meaning terribly well nor if that would actually help solve the problem. Separately, I think this is my second favourite video in this series so far and if you did do a video on the envelop meant of feathers I think that would take it's place, maybe even give old Dimetrodon a run for it's money (as that is my favourite of your series).
I like the way this guy rambles. Like he just knows a ton of stuff, and has to say things as he thinks of them, and "oh, yeah, I forgot to mention *THIS REALLY AWESOME THING*" I also want to see a committee meeting with this guy and some other paleontologists designing a dinosaur toy, with an artist drawing it on-the-fly. Then I want to buy that dinosaur toy, along with a copy of the debate transcript. THAT is the kind of TV I want to watch.
On the roosters, and puffing up their neck feathers, they do that mostly to intimidate other roosters, potentially to look larger and scarier. I see it all the time with my feathered treat eaters at home. If there's more than one rooster in a flock, one will sometimes be going up to bug the other one, and the other one is having none of it, so the fight display starts. Usually, that's all it takes to end the event, but once in awhile, there will be a bit of a scuffle. Then, the one that started the "argument" goes back to his little group, leaving the "boss" to go about his day in peace, again. When the display happens, though, they will puff out every single feather on their necks, from the ones long enough to "puff" right behind the skull all the way down to where the neck meets the body, itself, all the way around the neck. Their feathers stick straight out. Well, unless they're the heavier, longer pointed feathers (called the hackles or hackle feathers) that indicate that they're adult males, which go outward and then droop as they thin at the ends. They look ridiculous when they do it, to us humans around here, but they apparently say a lot to each other with the displays. As for display for mating, those feathers just don't really come into play for wooing the hens. They instead do this little dance, where they drop a shoulder and wing low, toward the hen, and do this little shuffle step sort of dance. Then they stop, look for something to offer her, like a piece of food, and make a little clicking sound that seems to say, "here you go, I got this just for you. Please enjoy it." It's amusing to watch. Even moreso when they do that dance to something that's not a hen of their species. I've even seen them do the dance to mammals like a dog or even one of us people! 😄 Our tom turkey's display is totally different, but I won't describe it here, since this is already really long. But this is my little offering of information on my own personal dinosaurs for anyone who might be interested!
Maniraptor wrists were an adaptation for climbing, as well as the long arms, finger claws, "terrible claws", flexible neck, splayed legs, et cetera. Basal maniraptors were arboreal, and possibly gliders. Later maniraptors developed into birds and larger ground dwelling forms.
I remember this toy! Safari Ltd's second attempt (MUCH better than the first, actually. I'm surprised that's not the one you're reviewing) I hope better ones come on the market. I want to say this one is from 2008. I think it mainly needs a better posture, more feathers, and a brighter paint job
I have the same model! I've collected a handful of these little guys (Giganotosaurus and Amargasaurus are a couple of my favorites) and it's interesting to see your critique 'cause I also thought the Theri looked a little weird - much less than the Velociraptor, but still weird.
Therizinosaurus is Mongolian, AND is the exception to the parallel to the ground rule? Well, all theropods had the hips parallel to the ground, EXCEPT FOR THE MONGOLS *But what about Tarbosaurus* EXCEPT SOME OF THE MONGOLS!
imagine how efficient it could have been, the mostly two leg walking style and the ability to stabilise with the strong arms aswell as use them as weapons, remember that elephant bears where also very good at moving giant rocks to build burrows, maybe this guy could do it too.
This has to be my new favorite dinosaur. I think the feathers and unique body shape made is stand out just as much as those massive claws. Plus it's an herbivore, which just takes the cake for a theropod.
I have an old dinosaur book somewhere, at the end it said something along the lines of "it could be a huge apex predator" or something.. the drawing was of like a forest, where we are exiting in first person, the firest to the side of us, and just grass down below, if I remember correctly.. there could have been a shadow or Im describing this wrong, if I find the book i'll update it.
Totally unrelated but megalodon lived in the Pleistocene right? Not the miocene? For some reason I feel like something in the back of my head says miocene but I'm like 90% sure it was the Pleistocene. Please correct me if I'm wrong
Just me but I think those claws serves something of a combination of Deer Antlers, Bird Wings, Hippo Open Mouth Intimidation, and/or Anteater Intimidation/Attack. For one, Deer Antlers coz maybe they use em for mating. To compete with other Males or to also Attract Females by maybe which competing Males can dish out the most damage or which one has the longest claws. Bird Wings coz maybe they attack by flapping or clapping opponents with it and using them similar to that of Anteaters. And they probably intimidate foes by opening it and making themselves look much larger similar to how Owls open their wings to intimidate. Kinda also similar to Hippos using their Mouth for intimidation by opening their mouth.
There are a lot of animals today that have ridiculously sized weapons that they use for competing for mates, like the antlers on deer. Many the claws were used similarly.
Puffing up the feathers could also be a threat display to make the animal look bigger and more intimidating. Imagine it splays out those big, clawed arms with the long filaments and it puffs out it’s neck and chest integument and then lets out a cry. That would certainly be intimadating to quite a few would-be predators, no?
The claws of therizinosaurus were only slightly curved at the tips so it used its claws to manipulate plants or to scare off predators like tarbosaurus.
its quite likely the claws were for both manipualting plant matter/dirt and for defence think of it like an anteaters claws, they are HUGE claws for an animal of its size, and they are used both for digging into ant/termite mounds, but also for slashing at any predator foolish enough to think it has a chance its not at all unreasonable to assume that as the animal evolved larger and larger claws for digging into trees or digging up roots, that it started to use these claws for defense as well and so lost its other forms of "defense" (such as running away) because with these huge claws it no longer needed them the idea of them being solely for defense makes little sense, as selection pressure would require the claws to come from somewhere first, if the animals predecesors used other methods of defence (again, like running away) it would have had no selection pressure for large claws, but if it was digging or breaking up food there would ahve been a pressure to get better at that, and so have bigger/sharper claws these bigger sharper claws which already had a selection pressure for gaining them, would then after the fact be used for defense and so in themselves be a selection pressure to lose the other (now unecesary) forms of defence so yeah, my money is it used the claws for digging up food, be it through actually digging or breaking apart trees or the like, and they just happened to be really good for defence as well
Toy company: All right, this guy has been complaining about how our dinosaurs don't stand up the right way, but I think we got him this ti- what... What... WHATWHATWHAT!?!

I think the claws had multiple uses
foraging, defense, marking territory, digging nests, and/or fighting over a mate
What about demolishing anthills , termite mounds or beehives?
They were obligate herbivores. They couldn’t eat insects. Plus they were too big for insects to make a difference

Imagine a Therizinosaurus, facing down a Tarbosaurus, it’s neck is thin and then bam! It’s really thick and fluffy. That would be awesome
Great stuff man. Thanks. First video of yours I've watched.
I’ve seen a more accurate Therozinosaurus recently I thought.
Ah yes, the Schliech Therozinosaurus.
I love the idea of therizinosaurus being a 10m pigeon 😍😍😍
So it's a floof monster with big claws. I shall call it, the murder chicken.
This has to be my new favorite dinosaur. I think the feathers and unique body shape made is stand out just as much as those massive claws. Plus it's an herbivore, which just takes the cake for a theropod.
I have an old dinosaur book somewhere, at the end it said something along the lines of "it could be a huge apex predator" or something.. the drawing was of like a forest, where we are exiting in first person, the firest to the side of us, and just grass down below, if I remember correctly.. there could have been a shadow or Im describing this wrong, if I find the book i'll update it.
"Don't discount the fluffiness." :D
Totally unrelated but megalodon lived in the Pleistocene right? Not the miocene? For some reason I feel like something in the back of my head says miocene but I'm like 90% sure it was the Pleistocene. Please correct me if I'm wrong
When he said it had to be a therizinosaurus I scream erikliosaurus lol
Now there's a man who has no idea what to with his arms. He knows his dinosaurs though!
Just me but I think those claws serves something of a combination of Deer Antlers, Bird Wings, Hippo Open Mouth Intimidation, and/or Anteater Intimidation/Attack.
For one, Deer Antlers coz maybe they use em for mating. To compete with other Males or to also Attract Females by maybe which competing Males can dish out the most damage or which one has the longest claws. Bird Wings coz maybe they attack by flapping or clapping opponents with it and using them similar to that of Anteaters. And they probably intimidate foes by opening it and making themselves look much larger similar to how Owls open their wings to intimidate. Kinda also similar to Hippos using their Mouth for intimidation by opening their mouth.
Talk about Deinocheirus!!
There are a lot of animals today that have ridiculously sized weapons that they use for competing for mates, like the antlers on deer. Many the claws were used similarly.
Puffing up the feathers could also be a threat display to make the animal look bigger and more intimidating. Imagine it splays out those big, clawed arms with the long filaments and it puffs out it’s neck and chest integument and then lets out a cry.
That would certainly be intimadating to quite a few would-be predators, no?
Oh! I was hoping to see coelophysis on your channel at some point! Granted, it's just an arm of one... Nonetheless favorite dinosaur right there 8:25
Bravo. I enjoyed this tremendously. Very educational.
The first dinosaur that actually walks upright
I found a therizinosaurus toy at my work yesterday that was completely without feathers and looked like the indo-raptor with giant claws.
The claws of therizinosaurus were only slightly curved at the tips so it used its claws to manipulate plants or to scare off predators like tarbosaurus.
This and plateosaurus would be in a different group as of the newer version of grouping for dinosaurs.
its quite likely the claws were for both manipualting plant matter/dirt and for defence
think of it like an anteaters claws, they are HUGE claws for an animal of its size, and they are used both for digging into ant/termite mounds, but also for slashing at any predator foolish enough to think it has a chance
its not at all unreasonable to assume that as the animal evolved larger and larger claws for digging into trees or digging up roots, that it started to use these claws for defense as well and so lost its other forms of "defense" (such as running away) because with these huge claws it no longer needed them
the idea of them being solely for defense makes little sense, as selection pressure would require the claws to come from somewhere first, if the animals predecesors used other methods of defence (again, like running away) it would have had no selection pressure for large claws, but if it was digging or breaking up food there would ahve been a pressure to get better at that, and so have bigger/sharper claws
these bigger sharper claws which already had a selection pressure for gaining them, would then after the fact be used for defense and so in themselves be a selection pressure to lose the other (now unecesary) forms of defence
so yeah, my money is it used the claws for digging up food, be it through actually digging or breaking apart trees or the like, and they just happened to be really good for defence as well
could you possible do an episode about feathers? I know you were half joking but, I would really enjoy it.
+Tony Crank We did! Episode 15 of this series.
