Stegosaurs were a lineage of armoured Thyreophoran Dinosaurs that thrived during the Jurassic Period. Possessing small narrow skulls, leaf shaped teeth and plated osteoderms running along their backs, these distinctive herbivores dwelt in Eurasia, North America and Africa. They were slow moving animals that used their spiked thagomizers to drive away predators. The group died out during the Early Cretaceous, likely due to a reduction in cycad plant diversity at this time.

Stegosaurus is and always will be my boy/girl. I don't know what drew me to Stegosaurus as a kid, whether it was the spikes, unmistakable profile, or feeling a connection because Stegosaurus never seemed to get any respect and neither did I. Had a bunch of Stegosaurus toys already, but the first Jurassic Park toy my mom ever bought me was a Stegosaurus that I held on to for 20 years. Inaccurate as it was even in '93, I wish I still had it. I had no idea Dravidosaurus wasn't a stegosaurid, or even a dinosaur anymore.

I love the ankylosaurs and all their kin, including the stegosaurs, because I have a thing about badass herbivores. Same reason I love giant ground sloths and glyptodonts from the mammalian age. There's the constant battle between predator and prey... and then there are these guys, who just go about their own business and don't prey on anybody except the vegetables. But heaven help you if you try to bother them -- you *will* regret it. They're great.

Crazy enough, the big Al survived that prehistoric, spiked, painful, groin shot. That would be a hilarious scene in the newest Jurassic World movie. Seeing insurance companies trying to figure out Dino damage, and a family trying to explain exactly what happened.

Recently visited the Natural History Museum in London, for the first time in many years. Sadly the Titanosaur display I went to see is now moving on, but there is a beautiful Stegosaurus skeleton reconstruction near one of the main entrances. There is also an impressive Tuojiangosaurus skeleton reconstruction in the main dinosaur hall. They put a lot of effort into making their displays interesting and visually appealing (the NHM I mean although maybe the stegosaurs did too!). There is also a brilliant animatronic reconstruction of two Deinonychus complete with feathers! And elsewhere an impressive Smilodon fatalis skeleton amongst many other prehistoric wonders. Excellent video presentation as always Dr Polaris, thank you!

@@carlosandleon that’s what I thought. But then I read about how when humans first showed up the large mammals die out. Whether we kill them or just outcompete the predators I don’t know. Like when humans got to the America’s the big things die. Something suggesting it’s true is that there is an island north or Russia where the wooly mammoths were alived when Jesus walked the earth. Long after the rest died out. It’s thought humans never got there til then. Also the island where huge reptiles lived like Komodo kept them big beasts cause humans didn’t show til few hundred years ago. It’s certainly not proven but the evidence ti me suggests that humans killed em off. Just as we mostly killed off the Neanderthal. Tho technically is European snow beasts have average a couple % Neanderthal so I guess in a way they are still here. At least some people… like Boxer Nikolai Valuev is pretty much one

Surprising that the enlarged rear legs were a derived feature. I always assumed that they were a holdover from being evolved from bipeds. So the only way to explain this feature is that they were tripedal browsers like giant ground sloths. Standing in a tripedal stance would however negate the effectiveness of the thagomizer so it’s unclear how this would work.

I was wondering about animals with sails and backplates, and I know current theory about them is that they're probably for cooling. But another thing they might've done is protect the animal from attacks from above by flying organisms, or much by larger predators that had to strike downward.

Wasn´t that "forefather of stegosaurids" a bit too "ankylosauriish"?

FUN FACT: stegosaurus is not stupid, its brain was actually bigger than a walnut

Colorado state fossil. They were pushed out of existence by the ankylosaurus branch.

phonetically DaSSentruros = Δάσος + Ουρά, Forest (dense vertical structures) for a tail/on a tail. Point being, it's read as an S and not a K. Yes, of course I'm Greek.

There’s sometimes so little artwork of the more obscure animals that I have use the resources that are available, even if it might not be 100% accurate.

@Naukumaija Mau-mau have you ever heard of David peters?

@Naukumaija Mau-mau nah it's cool. The issue is that people don't know him honestly but anyway. He's basically a crack pot artist who believes he is the one true source of accurate information even though he's never seen a fossil in person. He believes pterosaurs walked up right on two legs, that they were literally lizards, that mammals are lizards, and that pterosaurs had ridiculous structures. Look up his art sometime because it's a real shame how unironically talented that man is but his infor is just bad. Brian is that but for theropods. He believes that because birds are dinosaurs then that means every dinosaur had elaborate display structures and we're all neon. Unlike peters who just looks at blurry photos to justify his claims, Brian says that any soft tissue is possible in any extinct dinosaur even if evidence goes against it. He thinks that sauropods were neon blue and covered in quills and that mosasaurs swam like actual modern lizards rather than the aquatic predators they actually were.

@Naukumaija Mau-mau oh I'm fully aware but that's not the issue. The issue is that the scientific community has mostly denounced those reconstructions but those are the artists and reconstructions that are being put into museums

kids love dinosaurs but i find most have a fairly superficial understanding of the subject of paleontology, like they do of most things. therefore, to foster a joy of learning, they should be forced to memorise all known dinosaur names
