Description
Rubidgea atrox gives the name to the Rubidgeinae subfamily, and is its largest member. In fact, it is not just the largest rubidgeine, but is also one of the largest gorgonopsians in general, rivaling only Inostrancevia. Although its skull may be comparable in length to its Russian relative, Rubidgea's was remarkably more robust.Check also the Rubidgeinae from South Africa, 7 gorgonopsids that lived throught the same time and place: fav.me/dcmepf7

This is what humans will have evolved into in about 175 million years!

that's terrifying, did it really have front facing eyes like that?
👍: 0 ⏩: 1
To some extent, yes . That portion of the skull is very wide, what may reinforce this impression.

These beasts looked way eerier than dinosaurs.

Excellently depicted. The details on the skin are very on point, and you did a great job at depicting this animal's sheer bulk.
Speaking of skin, what led you to depict Rubidgea as hairless? Wasn't it likely that Rubidgea had endothermy to some extent?

Many thanks!
Just a guess, I don't rule out fur untill we have good skin impressions. Here I thought that hair could be a more advanced feature, while gorgonopsians still have a long way to a "mammalized" anatomy and look (no labial muscles, no sensory whiskers, no ears, no erect limbs, more basal skeletal characteristics... so I took fur as a similarly derived trait yet to appear in synapsids). If I need to bet while we don't have more clues on the hair origin, I'd say it developed closer to cynodonts, because we see more mammalian traits on them, including the first sensory whiskers.
Regarding endothermy, I think it is hard to mandatorily associate it to hair. Taking dinosaurs as examples, depending of when their filaments appeared, they had a long time with warm blood and no fur, and if feathers are no basal to them, some groups never experienced any filament (not my preferred hyphotesis, I consider more plausible some kind of filaments to be basal for dinosaurs; in this case, some groups still would have lost them completely). Taking mammals, some also reduced/lost hair and do fine without them, so endothermy probably was not correlated to a pressure to evolve fur.
But, as said, just a guess. We need more clues for when hair appeared xP

You raise some fair points, and honestly I can totally see where you are coming from. However, gorgonopsians did in fact have erect hind limbs, so they were not completely sprawled. Their feet are also symmetrical, which are another adaptation indicative of a more erect posture. They were already very close to achieving the erect postures seen in cynodonts and mammals.

Oh sure, was referring to the semi-sprawled arms. Should have been specific
👍: 0 ⏩: 1
Yeah.
And after all, remember the hair remnants that were found in those Siberian coprolites? Those could have been from anybody.
👍: 0 ⏩: 1
Yup, I know, from the Vianiski site. It is from the Latest Permian, near the transiction to the Triassic, so would match synapsids more advanced than gorgons. There are possibly more in coprolites from the Karoo, which may match gorgons, but may also be from therocephalians.
Well, only if they reflect the origin of hair, what can be older than these coprolites, of course.
👍: 0 ⏩: 1
If not gorgons, I'd say that therocephalians would probably have it. Some of the more advanced taxa have foramina that indicate the presence of vibrissa.

Poor guy, he is only... exotically beautiful haha. And I'm glad you liked it

Without a doubt one of the best reconstructions of a gorgon. And probably the best of the few life restoration of this impressive taxon. Next, the Middle Permian dinocephalian Anteosaurus ? The first therapsid with a Tyrannosaurus-like skull but almost twice the size of Rubidgea. In this sense, we should rather say that it is Tyrannosaurus and Rubidgeinae that have an Anteosaurus-like skull.

Kindness from you, that's far from be the best rendition of the animal ^^
You know, I'm wanting to do Anteosaurus for some time. Maybe it will appear in my gallery soon

A fangless cartoony gorgonopsian with ears! Seriously though, what a character design haha

Its supposed to be Moses.

I like this so much!
The skull has an uncannily Tyrannosaurus-like face, and it's really scary!

I'm glad you do
Yeah, there are some interesting convergences, like these skull bosses.

It has such a sadistic look in its eyes, man...

This is unbelievably amazing! I love how you portrayed him. His face resembles a human in a way and I find that so scary. This is so cool

Thank you so much! Yeah, animal faces get creepy and scary when we see human traces hehe

But awesome work of him nonetheless!

That honestly was a rather rude way to ask, and not the first time you act like this. If you want to comment and opine, elaborate your point with sources, or if it is your personal view, don't try to impose it, but simply commission the artist to paint the subject in the way you want. It is the first and only time I'll ask that politeness to you for possible future comments, and recommend the same approach to interact with other people. It is not rare to me to pass throught paleoart in DA and see you pretty much demanding artists to do things how you want.
Anyway, on the question, I assume you have Mark Witton's post in mind about the fangs - I know and understood his text, which is great and definitely should be considered to reconstruct these animals. Here the canines are bared because they pass the dentary edge when the mouth is fully closed , condition that is seen in even more gorgons, btw. I also wonder how well lip pockets for saberteeth (which I assume that would need to be more elaborated than pockets to common/smaller teeth) could work for simple labial tissue without the mammalian complex muscles and mobility, so consider totally fine to restore even species of shorter sabers with the canines exposed.

Now imagine it with a skull bigger than that of a tiger! 45cm of basal length!

Caramba, lindo!!!
Tá tão natural!
Vc acha que eles não tinham nenhum pelo?
👍: 0 ⏩: 1
Muito obrigado, Camila! Que ótimo ler que ele ficou natural!
Talvez os pelos já tivessem aparecido neles (ou mesmo em grupos mais antigos), acho a possibilidade plausível. Um dos casos de "especulativo até descobrirmos mais" hehe. Por enquanto penso que eram sem pelos ou com pelagem escassa, e os pelos "dominaram" num ponto mais próximo dos terocefálios e cinodontes.
👍: 0 ⏩: 1
De nada! Realmente ficou incrível!
Hm...interessante. Pq acho que esses bichos sempre ficam mais legais só com alguns pelos, tipo bigode, saca? Mas é aquele lance, não sabemos quase nada sobre a real anatomia dos animais pré-históricos. Ficará em nossa imaginação
👍: 0 ⏩: 1
Acho bem provável que pelos tenham começado assim, dispersos e distribuídos como bigodes, mas inicialmente sem a função "sensível" deles (isso só apareceu em cinodontes, aparentemente). Vamos torcer pra um dia ser encontrado um fóssil desses animais com impressões da pele

Sim, pra mim os melhores fósseis são esses que preservam detalhes da pele :3

Rubidgea may just be the most robust of all gorgonopsids, period.
👍: 0 ⏩: 1
True! There are other robust rubidgeines, but Rubidgea itself is simply enormous.

Nice, it's like a mix between a Tyrannosaurus and a mammalian predator with that skull.
