In the next installment of the Jurassic World comparison series, we take a look at one of the most interesting and unique entries into the franchise: Therizinosaurus! Therizinosaurus has been one of the most heavily requested animals for me to do this kind of video on and I'm very happy with the final result. After the overwhelmingly positive reception of the last video on Giganotosaurus, I'm very happy to continue this series for all of you guys to enjoy. Let me know which animals featured in this video were your favorites! And like last time, for a chance to win a copy of Prehistoric Kingdom, comment #Therizinosaurus in the comments below. Next up on the list: Dilophosaurus!

Regardless of how accurate the design is, I really did like the depiction of Therizinosaurus as much more vicious and territorial than the other herbivores in the franchise. A much appreciated breath of fresh air if you ask me. Ngl, with its aggressive behaviour, blind eyes and creepy sound design, I actually found it scarier than any of the carnivores. How about a video on T. rex or Pyroraptor next, please?

I’ve been a dinosaur nerd my whole life and when I saw the Therizinosaurus finally on screen, it was really exciting. I also connected that it’s blindness and it’s “if it moves, it’s a threat” kind of behavior reminded me of the anteaters of South America, Jaguars don’t often mess with them as anteaters essentially swing their claws blindly at anything in their territory, they do a splayed stance as a warning and I like to think the Theri’ did this in life as well. Wonderful video! The animation work is beautiful and I can’t wait to see more.

The blindness of the Theri could also contribute to the aggressiveness of it, as the creature cannot see it cannot exactly know what's a threat or not, so everytime it hears something it would either think it's be stalked or something else is going on, which would make it's fight or flight instincts kick in and it would attack whatever the threat is, just a random thought

The Therizinosaurus in JWD may not have been the most accurate depiction of the animal, but I won’t lie that it was awesome to see this incredibly bizarre dinosaur appear in the JP franchise, as well as more mainstream recognition. I personally like both the feathered monstrous design from the movie and the accurate reconstruction, at the very least it’s better than the “Joker” monstrosity that was the Giganotosaurus.

I like that they gave some dinosaurs disabilities like there's a juvinile baryonyx with a prosthetic limb and the therizinosaurus is blind. It shows that they are real, mortal animals and not terrorfying movie monsters. Love your videos man, I hope you make videos on all the jurasic park/world dinosaurs and non dinosaurs In this spectacular franchise. Stay safe and have a wonderful day.

I like that the movie didn't portray Therizinosaurus as another harmless herbivore, but I think that might be because of its large claws and history of being mistaken for a carnivorous dinosaur. If it didn't have those huge claws, then the movie would've portrayed it like how they portrayed hadrosaurs, which is disappointing.

its interesting how most of the accurate dinosaurs look cooler than their film counterparts

It’s ironic to know that the #Therizinosaurus was once thought to be a sea turtle and to find that some of the clone’s genome has turtle dna within it

Really love the idea of the “Scythe Lizard Turtle” having turtle dna

In my opinion, I think the Therizenosaurus blindness could be a result of an infection, the genome being broken while it was being made, or a genetic defect of some sort, with the Echolocation of the animal being it adapting to its blindness. But, the DNA with birds using echolocation is a valid guess, and I could see it work out.

definitely enjoyed this one. only problem I had was that the audio seemed pretty quiet, like in your other videos, but I can always turn up the volume. I like how you have your own artwork and animations, unlike other YouTube channels that use artwork from whichever artist they find online, and clips from documentaries and films or tv shows. can't wait for the next one.

Your designs are impeccable as always. As for JWD’s Therizinosaurus, I’m in love with the vocalisations they have for it and Giga. The hollywood roars aside, the bellowing and so on along with that twitchy jaw movements looks super cool.

Don't forget to comment #Therizinosaurus for a chance to win a copy of Prehistoric Kingdom!

Thoroughly enjoyed this video! Love the work and dedication you put into them! :)

7:56 omg that baby therizinosaur is so cute! ❤ I love when people like you and the guys who made prehistoric planet make baby dinosaurs so dang adorable!

"Not the best for stabbing"... fantastic shade at dominion haha. I think it's funny how #Therizinosaurus has basically the same stance as oudated theropod reconstructions. Thanks for the video!

I’m so glad you finally got a sponsor! This is a really enjoyable video and seeing you improve with every upload brings joy to me and many others!

The reason why Therizinosaurus is my favourite herbivorous dinosaur ever is because it shows us that just because something’s a herbivore doesn’t make it any less dangerous. I mean we live in a world full of Hippos, Rhinos, Deer, Elephants & Buffaloes they’re all herbivores and they can down right dangerous when needed.

I'd like to point out that the Theri in JWD also had a more horizontal and generic-theropod-shaped body, and a longer tail than the real animal. Great video, as always.
