Reminds me of all the incredibly outdated books I had as a kid. Am I the only one a little bit sad that all that old paleomedia was wrong? It seemed like a relaxed, slow, peaceful world filled with foolish beasts and swamps.
If thyreosaurus’ plates were flat like in Joschua’s reconstruction, then maybe if they had a courtship dance that involved leaning forward and down or turning their back to potential mates and then (temporarily) rearing up. I think this because the way that thyreosaurus’ plates were positioned makes it so that these movements display as much of the plates as possible. I also believe that flat plate could also have been used for communication that isn’t for mating dances but using the plates this way is harder than with typical stegosaur plates so I think it’s perfectly plausible (warning: HEAVY speculation) that thyreosaurus’ plates had a keratin sheath that was structured to be iridescent make up for the awkward angle of the plates. This could go for other stegosaurus but I believe that their upright plate are tall enough to not require iridescence for low-reward interactions (such as telling another stegosaur that they snore too loudly).
Thyreosaurus: * exists * Old Stegosaurus reconstructions with its plates down: You could not live with your own failure. And where did that bring you? B a c k t o m e.
Aw yeah, EDGE is back and he brought a weird stegosaur! Great overview, especially the paleoart gallery with all the different armor interpretations. I'd love to see more videos on stegosaurs; they're one of my favorite dinosaur groups but kind of underrepresented on YT. Maybe revive that series about dinosaur appearance changing over time, and do an entry on Stegosaurus?
9:58 My theory is it could be the ancestor of both stegosaurus and ankylosaurus due to the armour like pelvis then over time they split into different species or it’s just a really unique stegosaurus species
Both of those groups emerged from early thyrepphorans like scelidosaurus. So, though there would be transitional forms between scelidosaur-like and stegosaur or ankylosaur-like forms, there wouldn't be any that showed stegosaurs evolving into ankylosaurs. In fact, nodosaurs were around when stegosaurus was.
You forgot Minmi. When I saw a cast of a fossil cranium years ago I thought if humans and dinos had lived together Minmi skulls would have made stylin' Dino de Laurentiis-esque helmets.
Of all the spiked dinosaurs, which had spikes that were the most intimidating where even the fiercest of predators would avoid? It seems like all of those pictured here had weaknesses in the armor, like exposed sides and the dinosaurs with spike tails, were they really effective in battle?
You know, talking about all these new southern armored dinosaurs reminds me of the time paleontologists thought that the sauropods were strictly a northern hemisphere group of dinosaurs as well after they mostly disappeared after the end of the Jurassic. But now we know that sauropods were everywhere and the largest were from the south. Seems like history is repeating itself.
Amazing, since this Stegosaur is a much more advanced Stegosaur, I wonder what other adaptions Thyreophorans got throught their evolution. I personally still remain skeptical on this hot topic of debate. Thyreosaurus may have had plates, but at the same time, the specimen doesn't show too much evidence for this. Looking at their anatomy is very effective, but if we look at their evolution, the answer can vary. Those are just my personal thoughts and opinions.
They actually found a rock mummy of a I believe ankylosaur (probably spelt wrong) so we have a fully preserved almost sculpture looking dino.. it was found in sea sediment so the theory is it washed out to sea! :D!! I will provide an article if wished but Lindsey Nicole also made a nice video on it! (Edit as I belive I’ve said the name right 😅)
Technically correct, but it's often lumped into all of africa when it comes to ancient biodiversity. It was much closer to the equator during the Cretaceous.

It's actually looks like the first reconstructions of stegosaurus.
You mean the gliding stegosaurus?
@@joseflores1734 no, the biped tortoise one
@@Mayl0-YT oh yeah the 1800s one? Looks weird.
funny how we are going back to it lel
Now we gonna get paleoart of more stegosaurs w the plates lyin down
Yay, can’t wait.
That’s why the name means “roofed lizard” because this was the original interpretation
@@Wolfie54545 u know what they say about art reflecting the real world. This case its kinda true.
Reminds me of all the incredibly outdated books I had as a kid. Am I the only one a little bit sad that all that old paleomedia was wrong? It seemed like a relaxed, slow, peaceful world filled with foolish beasts and swamps.
Yet still majestic.
Seems like some herbivores were probably a bit derpy though.
@@kennethsatria6607 but their lack of faculties made them prime subjects for climbing and riding, at least in this fantastical world.
I'm so happy that you're back, your paleo content was sorely missed!

I always like seeing new discoveries about Stegosaurs! For being such a popular dinosaur it's hard to find new info about it!
The thumbnail painting makes it look like an aetosaurus
That specific bit of royalty-free music at 2:25 takes me right back to the Vehicle Assembly Building in Kerbal Space Program.
11:20 WoW, I used to read the book with that illustration so much as a kid! Paleontology sure has come a long way just under my lifetime.
Thyreosaurus: * exists *
Old Stegosaurus reconstructions with its plates down:
You could not live with your own failure. And where did that bring you?
B a c k t o m e.
first we got ankylosaurs with spiked tails now we got armored stegosaurs

I think the weirdest one was the kaiju sized robot one that turns into a surfboard for a combiner robot

It was an advanced stegosaur.
Ah yes, finally, the roofed lizard has arrived.
good to see u back!
Good to see you back!
It'd be cool to see a transitional species between stegosaurs and anylosaurs.
Both of those groups emerged from early thyrepphorans like scelidosaurus. So, though there would be transitional forms between scelidosaur-like and stegosaur or ankylosaur-like forms, there wouldn't be any that showed stegosaurs evolving into ankylosaurs. In fact, nodosaurs were around when stegosaurus was.
If only we had DNA, then we would know for sure if Stegosaurs and Ankylosaurs are related or not…
Oh, for what it's worth, they "definitely" are.
To me, it seems like Mid-Jurassic North Africa is becoming more & more fleshed out with its dinosaur roster.
You forgot Minmi. When I saw a cast of a fossil cranium years ago I thought if humans and dinos had lived together Minmi skulls would have made stylin' Dino de Laurentiis-esque helmets.
Minmi is an ankylosaur
This animal might be the missing link between ankylosaurid and stegosaurids. (You can correct me)
It came many millions of years after the two groups split.
I mean, stranger things have happened at sea. And in evolutionarily short time periods too.
That sure is a weird thyreophor
When will the new diplodocus be re uploaded?
Of all the spiked dinosaurs, which had spikes that were the most intimidating where even the fiercest of predators would avoid? It seems like all of those pictured here had weaknesses in the armor, like exposed sides and the dinosaurs with spike tails, were they really effective in battle?
Wait how do you spell the final paleo artists name? The one who drew this one: 10:51
Nice choice of using a Spore song as a background music at the first 2 minutes.
You know, talking about all these new southern armored dinosaurs reminds me of the time paleontologists thought that the sauropods were strictly a northern hemisphere group of dinosaurs as well after they mostly disappeared after the end of the Jurassic. But now we know that sauropods were everywhere and the largest were from the south. Seems like history is repeating itself.
I may be wrong, though, but it's just something I sort of noticed
0:42 so we just gonna forget the ceratopsians

It looks like Ankylodocus from Jurassic World Evolution lol
spore music in the back grownd
At this point rate we might find stegosaurs at the very end of the Cretaceous.
Your voice is relaxing
I was watching this while I was running my 3d printer. The whistling in the background made me think my printer was malfunctioning. x_x
What whistling?
@@EDGEscience It's part of the background ambiance.
6:03 what kind of stegosaur species is this?
Thyreosaurus lol
Possible missing link specoey between Stegosaur and Ankylosaur???
No, this guy evolved tens of millions of years after the two groups had already split.
Extremely fascinated Congratulations our teacher for this great work. 🇲🇦🇲🇦🇲🇦 Proud of you professor OKASSOU 🇲🇦🇲🇦🇲🇦
How large were these
Specimen found was estimated at 6m long but it was likely not fully grown
Thyreosaurus atlasicus
Спасибо вам. Я узнал несколько новых и интресных видов стегозавров. Надеюсь тайны тереофоров будут раскрыты и новые виды будут известны нам.
So is this the missing link between stegosaurs and ankylosaurs?
This guy is an advanced stegosaur well after the common ancestor between ankys and stegos.
Ok
EDGE IS BACK!!! SOUND THE HORNS OF PALEONTOLOGY
Impecable 👏🏼👏🏼👏🏼
Morocco isn’t in the southern hemisphere genius.
Technically correct, but it's often lumped into all of africa when it comes to ancient biodiversity. It was much closer to the equator during the Cretaceous.
Got a few bones. Let's make up the rest of the animal. Sure why not?
It's like a flesh puzzle it's fun
I edge to edge
Ark stego realistic fr
How about correct latin name pronunciation? 😁
ಠ_ಠ
on the one hand, i dislike all the weird stuff, stop breaking my old person world view! on the other hand,,, GIVE ME MORE WEIRDOS!
I've seen weirder.
I don’t know look pretty normal to me.
