Well, two birds with one stone is much less impressive when compared to the mass extinction of the dinosaurs... that's a lot of birds with one rock

The Therizinosaurus really is the platypus of dinosaurs.

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!?!

"Don't discount the fluffiness" Words to live by.

i just recently discovered this wonderful man and i am 100% obsessed

I like how he pauses before he speaks. Shows how he really thinks before he says.

The irony that the one time they made it correctly parallel to the ground.... it was upright

I showed my little sisters that picture of the floofy Therizinosaurus and one of them said "It looks like a fat emu!" And I responded with "It kind of _was_ a fat emu XD"

This dinosaur is weird as shit, I love it. Also, THE FLOOF.

Speaking of a "giant ground sloth" niche, the therezinosaur Nothronychus actually means "sloth claw".

From now on I will also call 'Ground Sloths' 'Elephant Bears'. Such the best name.

the tickle chicken

YOU DID DANGER FLOOF! The bizarre group of really odd features slapped together into one animal makes Therizinosaurus one of my personal favorites.

You had me at the bit where you corrected "advanced" to "derived." Truly a man after my own heart.

that has to be the cutest entrance yet.

Who does the amazing animation?

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.

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.

You don’t know how confused I was when I was taming one in ark and it ate fruits 😂😂😂😂😂. Biggest wtf ever

Please do a whole episode on where feathers came from, and why, and when, and how.

I think the claws had multiple uses foraging, defense, marking territory, digging nests, and/or fighting over a mate

Please do the "whole episode on where [feathers] came from"!

Kill two birds in one stone? There's only one bird in your hand. Unless you want the T. Rex and Dakotaraptor in the bush... but it's not worth it...

I really don’t know how these videos are popular. This is the kind of content that KZfaq needs. It’s a masterpiece with wonderful detail and animations

Time flies when you're watching YDAW.

I could listen to this guy talk about dinosaurs all damn day

There is something really charming and kinda cute about him, is that just me? I like how they edit these in a way where we get to see his thought process, he’s very real and decisive in the way he speaks and articulates. The bloopers at the end are great 😂

"Anything that makes it more likely for a creature to mate gets passed down so... don't discount the fluffiness". Such a great sentence xDDD

Easily my favorite series on youtube!

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.

Love the show! I'd definitely love to see an episode on the evolution of feathers I think that would be great!

I would LOVE an episode all about the origin of feathers!!!

So calling Therizinosarus a, "Danger Floof" wouldn't be wrong?

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.

"I get to kill two birds with one stone." Cladistics puns! XD

0:59 oh I thought it was called Madeinchina

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

Love the reflection in the white board of the half empty bottle of Absolute.

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 am absolutely enjoying this series! Great job and I'm excited to see what comes in the future.

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.

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.

What a fantastic find! Some binge watching of this series is in order for me.

Therizinosaurus is one of my favorite dinosaurs, so seeing stuff like this is really cool. Thanks!

I love going back and rewatching these while waiting for the one new episode per year 😂

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.

13:50 ..why have I just imagined a therizinosaurus fully covered in Steven's hair i feel cursed now

love your series, i tell all my friends about it, keep making more you good thing you! :)

Talk about Deinocheirus!!

Great stuff man. Thanks. First video of yours I've watched.

This channel is the best thing happened on my feed

This thing probably looked like a big, gnarly Silkie Chicken😂💕

I have to say I'm impressed, you managed to teach me new things on a dinosaur which I've learned a lot about (due it being my favorite)

Subscribed. I am impressed with this my first of your videos. I see this is 2014. I hope you are still making them

So... Therizinosaurus is a big herbivore derived from a carnivorous lineage? Cretaceous floofy pandas.

Found this video since I play ark. Therizinos are one of favorite dinos in the game and boy they look a lot different than what you describe lol.

Thank you for uploading on my birthday

Bravo. I enjoyed this tremendously. Very educational.

I really like this show, for real. I learn a lot, but I think it would benefit from having a more developed script.

15:03 That is the cutest animal that could use its fingers to easily disembowel me that I've ever seen.

You're having way too much fun with that fire engine at the end

In have the same exact toy, I'm excited to see it picked apart

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 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.

Please do a video on carnotaurus, I have seen some really bad plastic models that do a bad job of portraying it... :(

Kind of interested to see what his thoughts are in the dinos in Ark

Your best episode. Please do one on integument. That would be really interesting.

0:57 More like 'kill two maniraptors with one video.' From this day forth, I'm extending bird to include all maniraptoriformes!

A star is born

Love your videos i learned a much

could you possible do an episode about feathers? I know you were half joking but, I would really enjoy it.

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.

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

Gosh! Detailed. A lot of knowledge.

This is one of my favorite dinos!

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!

Very nice Video ! Could you do a Video only about feather? Pls

This and plateosaurus would be in a different group as of the newer version of grouping for dinosaurs.

Wow! What an amazing toy.

I'd like to see the full episode on just feathers alone ^w^ sounds interesting

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.....

Recently got my hands on a Schleich Therizinosaurus figure and i was fun to come back to this video and follow along with it. It's head is definitely big by all accounts and has no cheeks, but it's posture and claws seem pretty accurate, yeah! Even cooler is that, it's seemingly/roughly to scale with my tyrannosaur also from Schleich.. xD

I love the idea of therizinosaurus being a 10m pigeon 😍😍😍

Yes please an episode all about feather

Super fun! My favorite dinosaur besides deinocheirus!!

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

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

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.

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!

The intros keep getting better 😂

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.

I know you already did Spinosaurus, but I would love to see Baryonix walkeri, please. It's my favourite!

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.

4:51 id love a video about eoraptor

Curious what you think of The Isle’s model of a Theri. The jumbo butt feathers is one of my favorite concept ideas for a Theri.

OMG, can you imagine a creature the size of an elephant doing a mating ritual like a prairie grouse???

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 used to have that toy when I was younger

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.

I'd love to see a special on either carcharadontosaurus or giganatosaurus
