[@CrimsonAcro]

HELL YEAH! My favorite dinosaur of all time! It was an honor to narrate this and I can't wait for the next video!

[@MephilasSSeijin]

This was fun to animate in. Glad we were able to pull through and cook with this one !

[@SpinoDragonProductions]

I’m happy to have been involved with the creation for this video, and it was nice seeing how smooth the production was. Great job everyone!

[@joseluiscalixto5651]

The video turned out very well, you can see the dedication they have put into it. A big hug to all the people who collaborated 👋

[@Epoch_Now]

Thank you so much! 😊

[@Santagmk0]

Favorite dinosaur of all time right here, this video made it feel like a true king After watching this video: idk why but I cried at the end of the video, guess it goes to show just how majestic these beautiful creatures really were

[@Sauropodgaminggaming]

I love the soundtracks and the way it feels like a documentary.

[@theblazingredcomet1954]

Commenting for the algorithm, the high spined lizard needs high numbers. Amazing work from the team as always. Cant wait to see that video on dinosaurus 🤡

[@univerex-8061]

GOATrocanthosaurus

[@thedinosaurhunter3515]

Another fantastic video!

[@darkroom0716]

That FC5 music in the end is such a good track. Too bad the hymns on the game get all the attention because the more ambient guitar tracks really brought a serene mood to the game. As for the video, awesome. Love Acrocanthrosaurus, cool to see more on it!

[@melly_isjelly4001]

Slay love the video!

[@CrimsonAcro]

:D

[@DinoNerd208]

This was so amazing its very informative and put together really well and Acrocanthosaurs is such an amazing dinosaur! Some animals I would like to see would be maybe Torvosaurus Altispinax Miragaia or Titanoboa all of them would be awesome!

[@Epoch_Now]

Many of those are being considered as we speak! and thank you for the kind words!

[@DinoNerd208]

No Problem!

[@dagoodboy6424]

I live near acros old stomping grounds. I also found a dinosaur fossil last week.

[@rangogamer1386]

Happy to see it finally uploaded! Glad it's finally been uploaded!!!!

[@Tesod_]

Hi! Nice video I would be happy to see a video about Plateosaurus in your channel

[@Epoch_Now]

That’s a really good idea!

[@DavidWillisSLS]

Another awesome video!! Can you please do Dakosaurus!

[@straightupmurph559]

Based and Dakosaur pilled.

[@goldfishmentality]

Awesome vid bro! Gl with your dinotuber journey! Also asking for Sinotyrannus next lol

[@White-Fatalis]

Amazing video dude

[@maozilla9149]

nice

[@pedrogabrielduarte4544]

Do the ONLY Sauropod that Both lived and EVEN competed with tyrannosaurus rex: i'm talking of course about the TRUE king of dinosaurs:alamosaurus

[@BOEING--mh6xm]

[@CrimsonAcro]

This is the CrimsonAcro of Epoch Now, and my top 5 favorite dinosaurs would have to go in this order: 1. Acrocanthosaurus (c:) 2. Pachyrhinosaurus 3. Therizinosaurus 4. Giganotosaurus 5. Yutyrannus/Allosaurus

[@HassanMohamed-rm1cb]

Why don’t you also get to make a suggestion to create the KZbin Videos Shows about the Epicyon (“More Than A Dog”), the Bone-Crushing Dog on the next Epoch Now coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍

[@Epoch_Now]

Not a bad idea! However our next video will actually be about Amphicyon! The bear dog!

[@krishsankhe]

ARK reference???

[@bkjeong4302]

The second largest North American theropod and the one that attacked the largest prey, assuming that it was “only” going after subadult Sauroposeidon at most (which, with a sauropod that weighed around 40 tons as an adult, could still mean an 20 ton juvenile/subadult prey item.). Also, Deinonychus being solitary isn’t a given due to the studies arguing it couldn’t be social being based on inaccurate/outdated ideas about modern animal behaviour (to put it simply; no family groups =/= no social groups or no organized group hunting). That said Deinonychus could have been solitary-it’s just that the supposed evidence in favour of it is sketchy. And given how tiny it is compared to Acrocanthosaurus I doubt an adult Acro would regularly prey on it (why not attack a Tenontosaurus?)

[@theblazingredcomet1954]

You do realize that juveniles exist? They likely were faster than adults and consumed different prey. Sure Deinonychus wouldn't always be the best bet but it's not outside of the question. It's like a wolf hunting a fox, doesn't happen often but it does when times are tough or there's nothing else.

[@bkjeong4302]

@@theblazingredcomet1954 The video said adult Acrocanthosaurus would especially be prying on Deinonychus when the size difference is way too much to make that profitable; it would be the juveniles, not the adults, that would be a threat to Deinonychus.
