[knuppitalism-with-ue]

Some time ago we had the #PaleoZoo challenge on Discord, sponsored by Prehistoric Kingdom.

Goal was the creation of realistic zoo habitats that could hause extinct creatures. As examples I created a bunch of them over the course of a weekend.

Part three. A Shringasaurus temple, Archaeotherium getting brushed, Stegouros burrow, Plateosaurus hatchery, Wakaleo enclosure, Eryops colony, Lystrosaurus lookout, Giganthopithecus canopy walk, Australoraptor waterfalls, Numudotherium pond and the Erlikosaurus canyon.

71 million years ago as the sun sets before the subantarctic forests of what is now the Dorotea Formation of Chile, a pair of Gonkoken nanoi search the woods for flowers and leaves to eat from bushes while a Stegouros elengassen munches on a couple of ferns in the background.

VOTE STEGOUROS FOR DINOSAUR MARCH MADNESS 2023

art by Gabriel Ugueto

This is admittedly a really tough choice, but what is March Madness season for if not throwing your entire soul into campaigning against a random animal species for petty reasons? (disclaimer: this is from the guy who slandered Vaderlimulus for almost the entirety of Triassic March Madness before realizing that it never actually beat Atopodentatus in a poll)

I’ll try to keep this short since my previous Berthasaura propoganda post took a lot out of me and I actually respect Spicomellus as a contender /hj

A VOTE FOR STEGOUROS IS A VOTE FOR:

- an entirely new basal clade of ankylosaurs, only described less than two years ago, which survived until the Maastrichtian!

- the macuahuitl, which I believe is the first new type of thyreophoran tail-weaponry discovered in a long time

- asymmetrical, vaguely hourglass shaped teeth. what was it doing with those teeth? something cool, no doubt; I am a sucker for phylogenetic trends in feeding ecology 

- was apparently adapted for cursoriality, including with hoof-shaped claws? I didn’t even know thyreophorans could do that but yes please, all of that. Hello, new hyperfixation rabbithole

- south america! as far as I’m concerned, South American ecology has been Fabulous roughly since the Cretaceous and hasn’t stopped. Stegouros lived alongside unenlagiines! that’s really cool!

- a Little Guy™️. exhibit A, from wikipedia:

what a perfectly sized little guy. so precious and (comparatively) small, and this was a full-grown adult thyreophoran from the non-European Maastrichtian! As far as I know, Stegouros has no right to be that small. If it does, please tell me, as it will only make me love it more

- something known from a mostly-complete skeleton! so we actually have a good idea of what it looks like!

As much as I love Spicomellus for being so extra (osteoderms attached directly to the rib, first known african ankylosaur, earliest known ankylosaur, lived alongside a Stegosaur) it’s only known from a single rib bone. It is, admittedly, a really cool rib bone, but Stegouros also lots of really cool bones! And they all belong to the same skeleton! Spicomellus may come with some really interesting biogeography and ankylosaur evolution facts, but so does Stegouros! And Stegouros objectively has more neat anatomy than Spicomellus does, no matter how you slice it. Does Spicomellus really have anything to offer that Stegouros can’t offer just as well, if not better?

Vote Stegouros for the only remaining Cool Ankylosaur™️ with a remotely complete skeleton. For the only remaining definitely-a-thyreophoran with a remotely complete Skelton, for that matter.

Sunday 18/9/22 - Dinosaur Swords and Shields; Thyreophorans

Sauropelta - Sean Closson (twitter)

Apologies in advance if today's article is a bit more scatterbrained than some of my better blogposts in the past, but I've been procrastinating writing for a bit and need to get something out.

The larger group of Dinosauria is traditionally split into two main groups: The Saurischians (lizard hips) and Ornithischians (bird hips). The Saurischians include the Therapods (most meat eaters) and Sauropods (long necks), and have been the focus of a lot of my dinosaur discussion on this blog. So today, I wanna highlight a group from Ornithischia, the Thyreophorans.

Miragaia - TheDinosaurMann (twitter)

Thyreophora includes most of what the public would think of as "Armoured Dinosaurs", and much of the uniting anatomical traits are adapted for a thick set body, weight bearing limbs, powerful tails, and a general predator deterring lifestyle. The earliest and more primitive members of this group were more slender, and evolved from a bipedal common ancestor, but the most derived members were the heaviest, spikiest, and well armoured dinosaurs of their time.

Scutellosaurus, an early Thyreophoran

Gabriel Ugueto/Serpenillus (twitter)

One anatomical trait common to all Thyreophorans is the extensive covering of Osteoderms, bony skin protrusions that decorate and protect the backs, heads, and tails of many members. In the Ankylosaur division, this is mostly present as rounded studs and lumps all along the back and sides of the animal. In Stegosaurs, they present as spikes and plates along the back and tail of the animal. Before researching this topic, it never occurred to me that these were analogous structures, but it makes sense these features had ancestral roots.

To best demonstrate the diversity of Thyreophorans, I want to highlight three of the most recent discovered species from across the group.

Bashanosaurus

@ ttorrooo (on twitter)

This Stegosaur was recently found in China in 2015 and described in 2022. Its name means "Bashan-lizard" Bashan being an old name for Chongqing, where it was discovered. Current research places Bashanosaurus as a very primitive member of the Stegosaur clade, and it shares many traits common with Scelidosaurus, a Thyreophoran thought to have evolved before Stegosaurs and Ankylosaurs diverged.

In later Stegosaurs, the back spines had evolved into angular plates, thought to be primarily a display structure. But in Bashanosaurus, the back spines are still very spiky, and parts of its body still preserve rows of spikes on the side of the body, which were reduced to just one spike on the shoulder or lost altogether in later species. It still had the tail spikes, and this seems to be an ancestral trait. It represents a visual clue on how Stegosaurs evolved some of their more derived traits.

Stegouros

@adamworks (tumblr)

This dinosaur was a very derived Ankylosaur discovered in Chile in 2018, and described in 2021. It's name means "roofed tail". Ankylosaurs were traditionally split into two groups, Ankylosauridae, many of which had tail clubs, and Nodosauridae, which were often heavier built, and lacked tail clubs. These groups were mostly from northern continents, and Ankylosaurs from Australia and Antarctica were harder to classify.

The description of Stegouros prompted the creation of a new division within Ankylosauria; Parankylosauria, a group of Gondwana dinosaurs that diverged earlier, and Euankylosauria, which included the Nodosaurids and Ankylosaurids. While the Northern Continent Ankylosaurs were larger, and utilised clubs in their tail weaponry, Stegouros and its relatives were smaller, less bulky, and Stegouros had a sword on its tail. This tail was less mobile, the "sword" formed from several fused vertebrae, but it was still very dangerous.

Jakapil

Gabriel Diaz Yantén/ PaleoGDY (on twitter)

Video version linked here

This dinosaur was a basal Thyreophoran discovered in Argentina across the 2010s and described in 2022. Its name means "shield bearer" in the Puelchan language. Jakapil represents a lineage of dinosaurs that split off from the rest of Thyreophora before Stegosaurs and Ankylosaurs even split. But whereas most of the time you'd think "basal" or "primitive" means from an older time, Jakapil was from the Late Cretaceous, after most of the Stegosaur lineage had died out.

Thyreophorans were mostly heavy set animals, so quadrupeal locomotion was the norm, but Jakapil was an obligate biped; its arms were too small to walk on. It's well muscled jaw and unique skull shape has many palaeontologists theorising it was a basal Ceratopsian, but the advanced osteoderm armour/spikes on the neck, shoulders and down the back concluded it was a Thyreophoran. A very unique dinosaur indeed.

Thanks for Reading

Hi, if you haven't read any of my stuff before, thanks for reading this. This is sort of my dive into amateur journalism. This is not a dinosaur blog, but I do talk about dinosaurs a lot, so feel free to check out the links in my Pinned Post.

If you have a suggestion for something dinosaur to talk about, please inbox me, I am starved for creativity and would love the inspiration.

Painted a stegouros figure (bought from kayakasaurus) using my leopard gecko Cheeto as a color and pattern reference. I haven't gotten to do a dino figure re/paint in so long it was so nice to just chill out with music and paint again. I have a few other figures I can paint but they have serious seems going on and I keep putting off filling them :/ maybe 1 day.

UPDATE

it’s done!!

I’m pretty happy with how it came out, now that it’s done I realize that it looks a lot like the one from Kayakasaurus’ video (they’re also the person I bought the minis from) but I’m not complaining.

Hope the next one turns out just as good!

Dinosaur, Stegouros

Image © Luis Pérez López,  CC BY-SA 4.0. Accessed at Wikipedia here

[The scientific paper describing the dinosaur Stegouros elengassen was published December 1st, 2021. So my doing a stat block for it six months later might be some sort of record from publication to RPG incorporation of a monster. It’d be more impressive if this was a book, but w/e. The specific name, “elengassen”, is that of a Patagonian armored monster, which I covered under a slight name variation here]

Dinosaur, Stegouros CR 5 N Animal This dog-sized animal is low to the ground, with lean legs and a beaked mouth. Bony scutes grow from its body, especially along the tail. Its tail has a ridge of sharp bones on either side, giving it the appearance of a jagged sword.

The stegouros is a small, strange relative of the ankylosaurus. Unlike those living tanks, they are built less for hunkering down and trusting in strong armor than they are in making a speedy getaway, although their armor certainly helps them withstand attack. When threatened, they lash out with their stiff bladed tails, hacking instinctively at the feet and ankles of a predator. Such hobbled enemies have a difficult time pursuing the fleeing stegouros.

Stegouros live in rugged terrain. They are herbivores, feeding on bushes and shrubs and digging up roots and tubers. Because of the scattered vegetation in their environment, they usually live alone, wandering over great distances throughout the year in search of food. The young are precocial—they require and receive no parental care, simply hatching from a buried nest and making their way in the world from birth.

Elrohir glanced up smiling as his brave little stegouros hatchling got a sip from the small waterfall feeding rhe lake. Glorfindel balanced on the rocks near it watching the water carefully.

Glorfindel grinned as his sharp gaze caught the nearly camoflauged visage of the platypus as it swam swiftly to him. If one wasnt looking they would think it some wood caught in a current. Bending down slowly so as not to startle the hatching near him, he grabbed the brooch he tossed into the water.

"Very good little one! Your gaze has grown sharper and your speed more swift!"

The little platypus made a sosft pleased sound as the elf gave it a head pat. Unable to contain itself its tail slapped the water several times in its pleasure.

Elrohir winced looking to his hatchling who had been cautiously sniffing a frog on the rock. Honking in startled fear at the sound of the tsil slap it turned to run back to its elf.

Unfortunately it's tail swung wide smacking the back of Glorfindel's legs as he bent over the water. Elrohir watched as his uncle squeaked in a most unelven fashion and fell head first into the pond. He laughed as he lifted his cloak for his hatchling to scurry under shaking his head and offering soft reassurances.

The platchling dove down avoiding the elf landing on it, but quickly swam up beaking the golden mess of hair and grabbing a small chunk trying to drag him back to the rocks. Am save!!!!!!!!

CLUBSIDIAN (Rock) The obsidian bladed pokemon

CLUBSIDIAN (Club/Obsidian) Its body naturally produces obsidian shard that are as sharp as knives. Ancient civilizations would pick up this shards when they fell from their bodies and use them to make their tools and weapons., and when the pokemon died, they would use their tails and backs as clubs and shields.

CLUBSIDIAN is based on the Stegouros Elengassen, a recently discovered armored dinosaur from the order Ankylosauria , but instead of a club at the and of its tail it had a broad flat bladed tail that reminded me of the Macuahuitl, an aztec weapon that consisted of a large wooden club lined with obsidian blades, so I mixed both

Round Two: Stegouros vs Spicomellus

Stegouros elengassen

Artwork by Luis Enrique Pérez López, written by @zygodactylus

Name Meaning: Armored Creature with a Roofed Tail

Time: 74.9 to 71.7 million years ago (Campanian to Maastrichtian stages of the Late Cretaceous) 

Location: Dorotea Formation, Patagonia, Chile 

South America is just where the nonavian dinosaur party is happening these days! Stegouros is another recently described species from this continent, and another weird one - it was an Ankylosaur, but not a Nodosaur or an Ankylosaurid, and more to the point, instead of a tail club it had a series of vertebrae enclosed in osteoderms, in a shape that looked a lot like a macuahuitl - the tail was also very short, shorter than any other Thyreophoran, with flattened vertebrae coming together to form the strange and distinctive shape (similar short vertebrae are known from its relative, Antarctopelta). At around 2 meters long, it was very small for an Ankylosaur, though it had a head that was quite large for its body. It also had inward curving teeth, making them look vaguely hourglass-shaped, though they were also asymmetrical. It had many typical ankylosaur traits, but also some stegosaurian ones such as hollow sides to their vertebrae. Overall, it was very similar in proportions and appearance to Antarctopelta, indicating Antarctopelta may have looked more like Stegouros than previously thought. It had limb bones similar to cursorial Ankylosaurs, indicating Stegouros itself was a fast and efficient mover; and it even had claws shaped like hooves which may have enabled even more efficient running and locomotion. So, yeah. A short big headed ankylosaur built for running with a freaking ax on its tail. That’s normal! Living in the Dorotea Formation, Stegouros probably lived near the coast, alongside different sorts of mammals, fish, bivalves, amphibians, plesiosaurs, turtles, and unnamed dinosaurs such as opposite birds, megaraptors, Unenlagiines, and possible titanosaurs. 

Spicomellus afer

Artwork by @i-draws-dinosaurs, written by @zygodactylus

Name Meaning: African Collar of Spikes 

Time: 168 to 164 million years ago (Bathonian to Callovian stages of the Middle Jurassic) 

Location: Third Subunit, El Mers Group, Fès-Meknès, Morocco 

Spicomellus is the oldest known Ankylosaur, and also the first described Ankylosaur from North Africa! But that isn’t even the weirdest thing about it! Spicomellus had dermal spikes, fused to the bone, forming a collar (for which it was named) around its neck. Given that the spike were fused to the underlying bone - something no other ankylosaur does - it is probable that it wouldn’t have had a particularly flexible neck, or an easy time moving in general if the pattern continued throughout the body. It probably would have been around 3 meter long at the most, similar in size to other ankylosaurs from the Middle Jurassic. Coming from the El Mers Group, i tlived alongside Cetiosaurus, the stegosaur Adratiklit, megalosaurs, and teleosaurids. Spicomellus adds to a growing diversity of Jurassic Ankylosaurs, showing how Ankylosaurs and Stegosaurs lived alongside each other for a large period of time (the Middle and Late Jurassic epochs) and that the extinction of the Stegosaurs must have been due to a different, unrelated factor.

I’m bored, so GIVE ME JAVELIA + WAFFLES HEADCANONS!!!

Please? 🥺👉👈

Good morning this is a lovely thing to find in my ask box first thing when I wake up~ so I initially headcanoned that Javelia got a dog named mocha, and I wrote a fic on that. Now I’m considering to change it completely to the dinosaur named waffles IN MY HEAD.

Let’s see:

When Chiley come to take Waffles back to their dimension, Amelia is SOOOOOOO SAD. She doesn’t wanna let baby waffles go but Riley is like 😡 so she ultimately lets him go.

But waffles doesn’t wanna leave them and soooooooo *cue confetti* he jumps through the portal once again to disappear into nothingness. Amelia and Riley panic and Chase and Javi give them the “I told you so” look. Then they split up into groups to look for the baby Dino in whatever channels the wormhole leads to. It’s so chaotic and ultimately they don’t find Waffles ANYWHERE.

Finally, they’re tired, they’re sick of searching everywhere, so you have Javi inviting chase and Riley back home for some hot cocoa and marshmallows or whatever and the second they switch on the lights of the kitchen they find baby waffles eating a bunch of marshmallows from the tin. (How had he managed to open the tin you may ask? Let’s just say there was a very big hole in the top of it)

Amelia almost screamed, Riley almost had a panic attack, Chase and Javi were So HAPPY.

They decide to let baby waffles stay with Javelia. Chase promises he will handle Kendall’s ✨wrath✨ and WELP

So now Javelia are the proud parents of a little Stegouros. Waffles’s mom has been taught a way to Javelia’s place and she’s not pretty huge herself so yeah she visits from time to time. Waffles also knows his way around from one dimension to another— you’d think it’s hard to travel inter dimensionally, but seriously, how hard can it be if you’ve got me. FUcKiNg. Inter dimensional SUBWAYS.

Either way. They also visit the DC dimension when they need to visit the dinosaur vet. Everyone around them just casually knows they have a dinosaur, but somehow they haven’t been reported to the govt. authorities yet. It’s rangerverse, everything is weird.

And like you said, there is DEFINITELY a ranger-Instagram. (Gridstagram???) and you need your Morphin Grid Link to make an account (works for deactivated powers too. If you’re in Gosei’s database, you’re gonna get an account XD) best way for rangers to keep interacting.

Aiyon has a food blog on there, Javi and Amelia— while having their own accounts, also have a Baby Waffles page. Izzy and Fern have a sports page and Ollie has a tech page WHICH often collabs with Aiyon’s page where they just blow shit up in the kitchen.

Anyway so I think I strayed from the main point but They wuv their lil baby dino SO MUCH despite all the chaos he creates

And uh… he also brings them together when they break up angstily <3

[blizz4rd1203]

stego just refers to how they have some kinda shell or covering right

It usually refers to some kinda spike or weapon yeah

#stegosaurus and stegouros are technically related but only by virtue of stegosaurids developing into ankylosaurids #not through stegosaurus tho #stegosaurus is kinda not representative of stegosaurids as a whole
