Gorynychus: A Bone Crunching, Mammal-Like Predator From The Permian

- Gorynychus was a genus large, mammal-like predators from the Permian Period, long before the dinosaurs evolved. The genus included two species, Gorynychus masyutinae and Gorynychus sundyrensis. They belonged to Therocephalia, the sister clade to the Cynodontia, the ancestors of the true mammals. Gorynychus is significant for numerous reasons. Its fossils preserve evidence of behavior previously unknown in Therocephalia, it has helped to establish the global evolutionary trends of large Permian carnivores, and even helped to demonstrate that the evolutionary capabilities of large predators as a whole are far more expansive than once thought.

It's always interesting to hear that synapsids and diapsids really just switched roles after the two big mass extinctions. I bet most people just think think that mammals came from reptiles and became dominant after the dinosaurs when in fact it was a tug of war between our ancestors and those of modern reptiles. We just happen to live in a synapsid dominated time right now, but that might change with the next mass extinction, who knows?
I learned about this when i was young in Walking with Monsters. Suuuuper underrated doc and prolly the least known of the 4 Walking With series
@@hankskorpio5857 well it's way more known than the Walking with Cavemen series
next mass extinction may happens because of ourself
bird/or squamate takeover
Non-mammalian synapsids are one of those gems in prehistory that are so often passed over. Fact of the matter is that they're are our equivalent of the non-avian dinosaurs. The foundation for the many features we attribute to mammals started with them. Great video!
that is a phrase I am going to use now thanks
Therapsia is more our equivalent of Archosauria (both producing highly intelligent, upright, and warm blooded amniotes).
Gorynychus and Gorgonopsides "discovered" the Sabre teeth two hundred million years before the first metailuride
T-Rex: "I have the strongest bite of any animal!"
Gorynychus: "Hold my beer!"
T rex would definitely have a stronger bite...
The fact that someone made new paleoart specifically for this video is downright awesome, especially given the evolutionary significance of this therocephalian. Great job to Domenic Pennetta and great job to everyone who worked on this video!
This was a fun watch. I have to admit that I wasn't aware of these guys, my knowledge of permian animals is pretty limited because I've always been more interested in archosaurs, so it's cool to learn more about an area that I've sadly overlooked. The more I learn about how "advanced" a lot of permian animals were it really puts into focus that it might have just been a case of right place, right time that allowed the archosaurs to take over in the aftermath of the permian/triassic extinction. You can't help but wonder what the world would have been like had that event never occurred.
Now I'm just imagining bears the size of small housecats and a mink with a body the size of a very short legged giraffe
Love the Permian, more Middle to Late Permian fauna please. It will help you stand out from similar channels, where everyone seems to focus on covering similar genus/fauna.
The Mesozoic (especially the Jurassic and Cretaceous) and the Pleistocene to Holocene are very saturated with content. The Permian is a comparatively very uncolonised niche for palaeo-TH-camrs.
HELL FUCKING YES! Love that you took the suggestion and made a video on Gorynychus.
My next suggestions, if you decide to take them up, would be the potentially arboreal heterodontosaurid Manidens, the very basal archosauromorph Aenigmastropheus, and the uniquely well-preserved, frugivorous edaphosaurid Gordodon.
please do a video on Proborhyaena the largest sparassodont.
if the sebecids and phorurhacids were the equivalent of the larger theropod dinosaurs and sparassondonts to the dromaeosaurids, the Proborhyaena was the equivalent to Utahraptor.
Still far smaller than Barinasuchus, that was the equivalent of a Tyrannosaurid.
Really cool video, it's nice to see a video on something else than crocodylomorphs or dinosaurs from time to time, since I love the Permian in general. Only thing I suggest is if you have to mention many obscure animals with peculiar names it would be better to put the names so I can remember them and do some research after watching the video
This lineage illustrates beautifully how absolutely mind blowingly complex the development of ecosystems and evolution with said ecosystems is. Many like to think of these processes as either a single straight line of development, or one of branching routes, when in reality its much more like a constant scribbling web of repeating patterns and competition, and Gorynychus illustrates this perfectly! What an awesome video on such a neat genus! Great job as always mate!
Good video. I have heard of gorgonopsids but not of Gorynychus thanks for sharing this interesting info
Synapsids love evolving sabre teeth.
This was so epic and I love learning so much from this amazing channel :3
I find the shifting almost anagenetic evolution of Permian synapsid top predator clades confusing- this was a good entree though!
This is really interesting video! I didn't know that there was specialized bone crusher between Synapsids. And I didn't know, that Therocephalians were for some time dominant terrestrial predators. I always though that after extinction of Dinocephalianas Gorgonopsians took their place. Thanks for these informations!
This is possibly my favorite video of yours so far!
Thanks for the vid, even if its a synapsid this time.
;P
Cheers always good to hear about obscure critters of ages past.
2:08 Brutal Gorynychus does not even get a body in this picture, that is exactly the trick I use on that tricky species you just want to include in your scene, chuck in a big fat ole animal or some shrubberies. :P
Fantastic, thanks so much again for covering these fascinating and underrepresented species from this incredible era
One of your best videos yet! So informative!
I am glad you enjoyed it.
What a great video! I really enjoyed it, I've gotta say. 😁 Thanks for what you do, Chi, because you do these deep dives into stuff that generally isn't covered by other channels, and that's pretty bleeping cool!
Oooh, Permian synapsids? I remember making a comment on a previous video suggesting you take on something like this, very epic to see!
Just found your channel and am very impressed. You give full explanations of the diversity of species in each era including prey/plant life and the physical manifestations of that. I'm off to find another video of yours. You have a new subscriber :)
Thanks for this video. I didn't know about these animals.
Thank you so much for creating some great synapsid content. This group of animals fascinates me, but they are still not much talked about in paläo-media.
Thanks a lot for sharing this very informative interesting video!
Fantastic illustrations
💯
I am so FACINATED with these creatures!
Great video! Thank you for telling us about this interesting animal.
Nice work as usual, man! How about Anteosaurus next?
im hoping he does this one next because there are like multiple comments suggesting it and something I want as well
Great stuff thanks a bunch duggie
Overheard @The Society Of First True and Bonified Mammal Mothers meeting:
"They were nice enough, and all. But you know, and it's a shame, it is. Born just on the wrong side of the old evo thingy, and well, they're really not like us, being only "mammal-like", and all". ;)
Interesting video about a little know prehistoric species. Since you covered a lot of archosaurs before, would you mind covering obscure prehistoric birds in the future since they are also archosaurs? Some suggestions include elephant birds and pelagornids.
I actually I am already planning to cover the elephant birds in the distant(ish) future.
@@chimerasuchus Thanks!
Can you do a video on Anteosaurus next and also other dinocephalians like Titanosuchus
Moschops
Very interesting enjoying mote of the pre dinosaur periods that still had significant interesting creatures. Thank you
I didn't know about those reptiles. Thanks for teaching me about them.
not reptiles
do more on therapsids
Liked!
Greetings bibia
Another great video 😎 (sorry for being late, I moved from my old apartment)
Please could you do a video on your favourite hadrosaur
There could be another reason for the unusually worn down tooth.. Animals that are starving will eat almost anything in desperation- is it possible that the tooth came from a starving individual?
I suppose it is. Good point.

"Semi mammal like" how?
"Semi mammal like" is never said in the video so I am not sure what you are talking about.
on what physiology do you base your thoughts that they were not warm blooded. ?
with a bird like metabolism?
Therapsid bone histology has found traits typical of warm blooded animals and growth rates far above what ectotherms are capable of. However, their metabolisms were still not as high as modern mammals.
@@chimerasuchus So mesothermic
The actual pronunciation of the name is "Go-ri (like in "Gorilla") - ni - chus (like in "chilly")"
Excellent. Subbed.
Noc like I did .now I question myself .questions I've asked before ....
@9:50 what is this big Gorynychus called? It looks so cool.
It is Moschorhinus.
The "ch" in Nochnitsa is not a "k" sound. It's supposed to be pronounced like in "chair."
Great video
Thanks!
@@chimerasuchus your welcome
"Therocephalian" is pronounced "ther-owe-cef-A-lee-an. There is only one "i" in that word, the one that comes in the last two syllables, "li-an."
I wonder about the evolution of mammalian ears. When does itu develop into more than just a hole on the sides of the heads? Maybe a video about this??
It is tied to the migration of certain jaw bones into the inner ear.
Fascinating topic choice
I'm pretty sure the idea that large terrestrial carnivores cannot diversify in morphology (they obviously can in niche) is while they are big. There is no reason they cannot evolve to be small first.
Might as well be on a hostile alien planet.
Enjoyed. But probably too confusing to someone not have some basis in paleontology.
(of synapsids) "the distant relatives and ancestors of mammals"
- mammals are synapsids themselves!
Prehistoric life is just so cool
As an advocate for the synapsida clade, i approve
Are some (spelling?) Therosephalians poisonous?
I think Euchambersia was, and poison and venom are two different things, poison is applied after ingesting a part of or the entire animal, meanwhile venom is injected by the animal itself into it's target with fangs, claws, spikes, etc.
Commenting for Al Gore's rhythm.
mammals before mammals
no
do anteosaurus Next.
Why no ears? It's bothering me 😟
Anteosaurus/Eotriceratops next.
This I always wanted to see an in depth video on anteosaurus they were predators bigger than inostrancevia and I heard they were fast as well.
I would absolutely love information on Eotriceratops, this giant Ceratopsian, perhaps bigger than Triceratops itself always fascinated me, however, information on it is relatively scarce, especially in video form.
I wonder which other extinct creature you’ll talk about, maybe from another lesser known family
More like Cutienychus
always a teaching mistake to draw full body art when you do not have full body
skeleton . leg placement , under body or angled out very important and unknown. .
Plenty of other therocephalians limbs have been found. Combined with the Gorynychus limbs bones that have been found, it can be reasonably inferred that its legs were erect like its relatives.
R.O.U.S.'s 👀
How is 'gory' self explanatory? Those who named it did not speak English. Your pronunciation was so bad that I could not at all make out what this animal was named after. You also failed to tell us where these fossils were excavated. I heard something like "sundir assemblage' but could not find any trace of such a term online.
The use of "Gory" for that purpose was specifically cited in the paper and one of the two paleologists who named it, Christian F. Kammerer, is an American. Gorynychus sundyrensis is from the Sundyr Assemblage. I am not sure how "Sundyr" is produced (and not for lack of trying) but it is spelled correctly in the subtitles.
some of these pictures make them look like giant rats or R.O.U.S.

Don't narrate anymore
