The “cat-like” creodonts (oxyaenids) had dentition suited for crushing. While the “dog-like” creodonts (hyeanodonts) had dentition suited for slicing. The opposite trend generally applies for carnivorans. Pretty amazing.
Super weird, and super cool! Thanks! I am very much looking forward to the Orang Pendek, and any evidence that it is still out there, and the chances that it is an extant group of Homo Florensis.
@@dr.polaris6423 thank you Dr, another great video on a group I didnt know about. I always read about nimravids and Barbourofelids being the cat mimics haha. Great video!
To be pedantic for the sake of accuracy, but without any negative intent of implication. If they came before cats, doesn't that mean they were precursors, rather than mimics? Sorry, aspergers. Really learn a lot from you, thanks.
Nice and interesting, I just know about Sarkastodon and their size can be compared to Andrewsarchus mongoliensis. I am indonesian, I cant wait for your Orangpendek video from sumatra island, Indonesia :D
I looked up the temporal range of Sarkastodon and Hypercoryphodon, because the swamps of Mongolia at the end of the Eocene sounds really interesting. Hypercoryphodon lived 34-37 million years ago and Sarkastodon and Andrewsarchus lived roughly 37 to 44 million years ago. This is wikipedia of course, so I thought I'd check with an expert. Did all these creatures live together as you state in the video?
This reminds me how in Madagascar there is convergent evolution adaptations with the predator mongoose type creature that filed the cat type niche in the ecosystem. The Fossa
Actually, Sarkastadon's name is related to sarcasm. Sarcasm literally means to rip at the flesh in Greek (σαρκός is flesh), and Sarkastadon's name means fleshy tooth.
At one time the idea that Patriofelis was carnivorus was disputed with the claim that the wear on teeth was more consistent with an vegetarian lifestyle. An even earlier paper claimed a carnivorus diet with a Twitter-like lifestyle with the ability to climb. Just curious as to how these questions were resolved once again conclude Patriofelis is back to being a tree-living carnivorous oxyaenid?
That art's a good attempt, but it's wrong. Most of these Oxy-fangers (we called them Oxy-fangers back then) actually wore pants, at least most of the time. :) ...nobody actually knew where they got those things, though...
"it should be said that CATS are the ones that mimiced Creodents cause they where there far before cats and dogs" - no, both you and the title (vice versa) are wrong. You clearly don't understand mimicry - mimicry involves taxa coexisting and evolving alongside each other in the environment, not applicable here
So many of these carnivorous lines went extinct when the lone big cats and the wolfs came into existence. The first more powerful hunters as well as runner, while the second socially organized hunting groups and better runners. I think its Plantigrade hunters just weren't fast enough to compete. If the bears had developed a taste for plant food, they would have died out.
….no just no. The timeline in no way actually supports this. Oxyaenids went extinct too early to be outcompeted by large cats or pursuit-hunting canids, while hyaenodonts were digitigrade or semidigitigrade and actually managed to coexist with various large, hypercarnivorous carnivorans including the highly catlike nimravids and even some actual large-bodied cats. And cats are NOT good runners as predatory mammals go (with one big exception). They’re specialized for ambush hunting, and their digitigrade stance is likely an artefact of their ancestry-especially since some cats actually became less digitigrade over time (Smilodon for example had flatter feet than most digitigrade carnivorans, as did some other sabretoothed cats). Also, mustelids are plantigrade and do fine competing with small cats and small canids.
Sarkastodon. Nothing to do with 'sarcastic'? So you know your Ancient Greek, do you? Sarkastodon would mean 'flesh-tearing tooth'. Our adiective 'sarcastic' literally means 'flesh-tearing' but we use it a touch more figuratively than that. Why do biologists, botanists and medics not learn Greek? 90% of your terminology is Greek (with just a splash of Latin.) By the way, don't try and sound French when saying the Latin word 'genera' (sing: genus). Okay, off you go now.
Grizzlies which shouldn’t be very fast Actually run down ungulates. And catch them. It’s almost like the movie cliché of the shambling mummy always being able to catch people given how fast it looks like he movies. Given that bears given how there body holds lots of fat. They are able out stamina a lion.
This is the channel for obscure taxa. Amazing stuff
Thanks! My main aim is to give these obscure groups some wider recognition.
@@dr.polaris6423 isn't Cats themselves actually mimicked Creodonts themselves. they where there far before cats and dogs

I haven't heard about oxyaenids before, thank you for bringing this fascinating group to my attention!
No problem, glad I could spread the word!

So happy this popped up in my feed.
Glad you liked it!

Cheers, I’m looking forward to researching the Orang Pendek. One of the more plausible cryptids.
I like to visit this channel for relativly obscure group from past.
Thanks, that was always my aim with these videos.
Sarkastodon in a nutshell: CAT BEAR
@@kateaveryavery1342 mastodon: boobs tooth.
sarkastodon: meat eating tooth.
Always great to see someone covering more obscure ancient mammals.
Another great video
Thanks!
so glad I found this hidden gem of a channel! I love your content
Loved the video, so deep and informative. Definitely got yourself a new subscriber!!
Great video, with wonderful detail. Thanks for this!
What's the amazing music in the background? Getting serious Jungle book vibes haha
Yeah it really does sound like the Jungle Book! Look up Hozen theme and you’ll find it.
@@dr.polaris6423 thank you Dr, another great video on a group I didnt know about. I always read about nimravids and Barbourofelids being the cat mimics haha. Great video!
Man I love your intro so much
Spectacular work. Thanks
Yo keep up the good work
It certainly took carnivorous mammals a long time to develop effective claws for bringing down prey. Most of the early ones were bite-only.
Great stuff!
Great video and a great channel, keep it up! big fan from NZ
Cheers!
I'm loving your videos! Nice pace.
Dr. Polaris is what happens when you let the Polar Bear evolve another 20 million years.
They look like a cross between feliforms and and mustelids.
It cant get much scary then that. Hybrid cat-mustelid.. Two of the most terrible predators.

Yes you'd be correct there!
Fascinating! Great episode!
That looks like the cat Pepe' Le Pew fell in love with 😻
Great video as usual, we do need a figure of sarkastodon from papo collecta or safari Ltd.
New subscriber here. Your vids came up in my feed. Love them!! Keep up the good work!

Any idea when the orang pendek video will be up?
In exactly two weeks from today!
Could mustelids (weasels) develop sabre teeth like they did in the Future is Wild? It seems mammals keep evolving sabre teeth.
"With a name in no way related to sarcasm" 😉😉😄 My favourite line in this video! 🤣

Patrofelis had been the subject of an intense debate as to whether oPatrofelis was a vegetarian or carnivorous.
Did oxyaenids compete with sparassodont marsupials like Thylacosmilus in South America?
Nope, seeing as Oxyaenids were only native to Eurasia and North America.
@@dr.polaris6423 Ah, thank you! 😊👍
The panama land bridge was formed in Pleistocene only
Actually, Sarkastadon's name is related to sarcasm. Sarcasm literally means to rip at the flesh in Greek (σαρκός is flesh), and Sarkastadon's name means fleshy tooth.
Love this
I wonder if any of the Oxyaenids would've med good pets?
Well, technically there isn't any direct fossil evidence that Sarkastadon WASN'T sarcastic.
Creodonts were the best , they helped the carnivorans evolve and flourish by fighting the hooved predator's.

I always thought of sarkastrodon
Not hyanedont then
Oxyeanid
So... Not only from Nimravids, Cats also resembles Oxyaenids...
TIL
Expect they... not.
It's really called sarkatodon? Yeah,right, sure. That totally a real name.
Who are the mimics? The animal that lived first or the animal that exist today? I would say that the Cats mimic the Oxyaenids.
From what i have understood, the cat mimics were before and they evolved into true cats
[eyeroll] Oh, suuuure sarcastodon's name has nothing to do with sarcasm…
You sir have a sub👍🏽
Why didn't you upload last week?
did. you not see the thing abt how because of life stuff he's uploading twice a month now
I’ll be uploading every two weeks for a while due to extra work outside RUclips.
Evolution and Extinction is inevitable
It would be crazy if the tail was prehensile....
So it's not a cat?
Nope, not even Carnivorans either.

wow!
That art's a good attempt, but it's wrong.
Most of these Oxy-fangers (we called them Oxy-fangers back then) actually wore pants, at least most of the time. :)

Is that your actual voice??? Comedy right?
What if creodonts never went extinct? 🤔
Tenia forma felino
funny thing is. it should be said that CATS are the ones that mimiced Creodents cause they where there far before cats and dogs

INCREASE THE VOLUME!!!
The title is nonsense, there is no mimicry here.
Algorithm comment
The periodic showing of this rather stupid looking polar bear is very distracting and unnecessary. Your content is interesting but lose the bear.
Sorry you see it that way. Just my internet persona.
I just found my totem animal! Sarkastodon. Of course, extinct, which is just my luck!
