Tiarajudens: Saber-Toothed Permian Proto-Mammal
ฝัง
- เผยแพร่เมื่อ 17 มิ.ย. 2024
- Tiarajudens was a distant relative of mammals notable for its long, saber-teeth. Rather than hunt with them, as was done by saber-toothed cats such as the famous Smilodon, Tiarajudens is thought to have used its saber-teeth as display devices and to fight rivals of the same species. Indeed, unlike other prehistoric saber-toothed creatures, Tiarajudens was a herbivore. It lived in Brazil during the middle of the Permian Period, tens of millions of years before the rise of the dinosaurs, and when proto-mammals like it were the dominant terrestrial fauna.

Several of the pictures used in this video make these creatures look honestly quite cute.
Speaking of parareptiles, I think it would be a great topic for a long video. In world of obscure reptiles, the "near reptiles"/anapsids are forgotten 10 times over. Aside from the being the Gorgon's favorite food: Scutosaurus, no paleotuber has done a end to end rundown on them and nobody knows about them. They lived throughout the Triassic until the TJ extinction! They strongly influenced proto-mammal evolution.
Yasss! New video and original narrarator is back!
And the mispronunciations are back as well. 🤮
@@nathancomixproductions466 surely you could do better
@@posticusmaximus1739 How do you mean by that?
"How do you mean by that?" Bad grammar. 🤮
"Mispronounced" my brother in christ it's Latin it literally can not be Mispronounced
Thank you yet again for a fascinating video on an obscure prehistoric animal, one that just like the others, deserves much more of the limelight!
The obscurer the better!
Glad you're back✊️
This channel is what i wanted for a long time one that presents the weirdos of the permian and triassic and other weirdos that almost noone know abaut
I think many of us are imagining the displays/contests between male hippos. Which in my case leads me to wonder does this sort of contest leave evidence in hippo skeletons?
Permian stuff is always mind blowing for me
Evolution is crazy
I wana see what stuff we find on other planets. 😂
Been awhile Chimera, good to see you back. BTW nice Synapsid subject.
Although I've always loved dinosaurs I've been learning so much lately from your channel and from others. The suchian family was so much more diverse than I could ever have imagined. The Synapsids are just as varied and just as interesting. Well-paced narration and some beautiful images.
Glad you’re narrating again!
Good to have you back, my friend. I like both narrators.
Me too
More permian proto mamals please especially the predators!!
I'm gonna he honest, I really enjoy your narration a lot more than the others who've appeared on this channel. It's not world renowned or perfect, but it has a much better vibe imo
Synapsids love sabre teeth.
Now i know y nobody talks about it.
Its a rare herbivore.
Im glad u revowed it. I like to think it faught like a walrus.
That unmistakable voice.
Reminds me of that Sheldon character from that nerdy sciencey comedy a few years back. Big Bang Theory. I like it too. "Sheldon ASMR", lol...
I remember seeing these in a book when i was a kid i always assumed they were basel gorgonopsids cool to see they were theyre own thing great video👍
great to see this video... i enjoy hearing about proto-mammals
Thank you very much. Good material, thoroughly presented.
Missed you!! And you really should narrate your own videos
It's been a long time I've heard your own voice
Glad you’re narrating your own videos again!
Always good to be early! Great vid
Thanks
Fantastic video, as always, and fantastic to hear about species I have never previously heard of.
There's an infinite supply of that!
Наконец-то новое видео
Thanks a lot for providing this!
For the record, I actually prefer your own narration.
so good
Another interesting permian critter!
This was cool!
HEY I LOVE THE VOICE! HES BACK!
Great video
Great vídeo, just one note, the "j" on tiarajudens isnt pronunced like an "h" or "y" but a soft j sound, since that's the way it is in portuguese, the namesake is also pronounced "tee-ya-ra-j-oo" or "tee-ya-ra-shh-oo"
English speakers never seem to get our J right
Actually, the definitive answer is : pronounce it in the Latin way. Let's not forget Linnaean binomials as well as all taxa in systematics are Latin words. And in Latin, the "j", which doesn't exist as such in classical Latin", is pronounced like an "i". Those are the rules.
@@raminagrobis6112 I bet you don't call a velociraptor a "u-ē-lo-ki-ɾa-p-toɾ", Ego latinam languam studeo, sed basically no one pronunces taxonomical classification "correctly".
Moreover, not all taxonimcal names come from latin, with greek being just as used (if not more used) and a lot of words being borrowed from different languages aswell, like Tiarajú, that comes from the Guarani indian language.
In most cases the way you pronunce it comes from its namesake, the taxa is named after the Vila of Tiarajú on Santa Maria (famous for the formation of the same name) and a place I had the plesure of visting a couple of times.
Pronuncing with a "y" sound might not be wrong based on latin pronunciation, but it's still preferable to keep the original "ʤ" sound from the source of its name.
@@cabinessence_timely_hello I did 5 years of Latin myself. So you are still studying it? (You used the Present time ).
Anyway. Back to the pronunciation. You seem to be confounding the colloquial or vernacular pronunciation with the Latin one. All I was saying is that for the same reason the Linnaean binomials are still used for the purpose of international communication as a common standard in writing. When time comes to saying those names in Latin, one should stick to the Latin way to pronounce it, in principle.
Secondly, you seem to be dancing on one foot and then the other. You favor the Latin pronunciation when time comes to pronouncing the roted "j" (which is what I was saying!) instead of the Portuguese way.
By the way, I am NOT saying that one applies that principle in your everyday communications in biology. Especially nowadays, as fewer and fewer biologists have ever studied Latin. My point was simply that in matters of deciding which is the "right" way to say these binomials, ultimately, it IS the Latin way that prevails. Otherwise, some words originating from languages with which some cultures are less or not familiar might be unfairly massacred.
There is a reason for the standard nomenclature. I was answering the person who was advocating the use of the Portuguese pronunciation. It is a nice gesture if one means to please a Portuguese in the audience. But that's not that how Latin names are conceived.
Thirdly, the point you make about Greek is a moot one. Latin of course has heavily borrowed from Greek,well before Linnaeus coined his system. Romans did not keep the Greek way, and these words were then pronounced in the classical Latin manner.
Fourthly, no, I wouldn't say Velociraptor the way you suggested, if you mean in English. That's why I was referring when I mentioned the confusion.
In final analysis, I'd say: go with how the audience is mostly expecting one to say it. The 'principle' that names should be pronounced as Latin does is NOT currently enforced and I wouldn't,t even personally advocate it ROUTINELY. Again my point was to answer the person who asked you to pronounce it "à la Portugaise". I meant it to emphasize the fact that there is no "correct" way to pronounce Latin names other than to stick with Latin. It is the standard. In practice, one goes with the current. I hoped I was clearer.
@@raminagrobis6112 That's a impressively well written comment; I'm a biology graduate from the State where the fossil was discovered, and as I said, when pronuncing latin names colloquially is preferable to go with the original pronunciation regarding the namesake, since most wouldn't pronunce latin correctly to begin with. Maybe this assertion is not the stardard, but it is what I learned formely. In short, the correct latin pronuncation is with a "y" sound, however, colloquially we strive for the original namesake pronunciation.
About latin, I've been studying for a while at this point but I'm not completely fluent on the language yet, or I woudln't called myself 100% fluent, that's why I said "I study it", not "speak it", I don't feel I'm done with it yet.
My original comment wasn't about the latin pronunciation at all, but about the colloquial one, and how Chimerasuchus got confused and mixed portuguese with spanish and latin, and said both "tiarahu" and "tiarayu" in the video.
My second comment was on answer to your point of "the way it's pronunced in latin is the correct - those are the rules"; well, as you said yourself, there is no rule that says "always pronunce it on latin".
Personally, I always go with the latin pronunciation, only going colloquially when I have to explain to people who are unfamiliar with it or talking about taxa with commonly used names (like velociraptor).
Awww...it's like one of those fanged deer..
Cool content
Great narration
Thank you very much!🌹
Tiarajudens: first land walrus
Quite interesting !
Great video. Great voting choice by your members. I'm fascinated by the Permian era, with its protomammals and monstrous extinction event at the end. More of this please! ;)
Anomalocaris was the original sabertooth
???
i think those were like early pincers
It didn't even had sabertooth💀 Tf you smoking bruh☠️
Oh hey, the real CHimerasuchus is back narrating, cool!
It's like the vampire deer with long fangs
I remember in the old books these critters were always referred to as "mammal like reptiles."
Do you take suggestions? If not already? Can you do a video titled "The Bird Diet Mystery: Gastornis" about Gastornis and its debate of diet.
I think their sabers were used as a defensive weapon as a primary use. Like a stiletto snake, minus the venom. They look like they could easily stab anything that tries to grab them, especially swinging to the sides.
I’ve got some great ideas and some great suggestions for you to make TH-cam Videos Shows about some more Prehistoric Extinct Crocodilian Species, such as Lazarussuchus, Plesiosuchus, and Metriorynchus adding that to the episodes on the next Saturday on the next Chimerasuchus coming up next!!👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️
The Permian had very strange animals, like something from an alien planet, but that was Earth 250 million years ago.
Why do you have an issue with doing the narration yourself, I think you're quite a good narrator imo
Brazillian fauna mentioned
This reminds me of a kajiu call maguma
😮
woo
We're back, fellow sapiosuchuses 🐊
cute
It's always great to learn about another synapsid, what a bunch of weirdos!
Odd how the more mammal something is the smaller the tail..
Ekspecially he says
So you won't be uploading videos to TH-cam anymore?
I will. TH-cam Memberships is just TH-cam's equivalent of Patreon.
@@chimerasuchus oh, great. I was kinda worried for a second. 😅
@@mukhtaralbahlani5273 Yeah, the name "TH-cam Memeberships" is just a recipe for confusion.
i like this channel more when you pay someone else to do the voiceover.
my brother in christ you sound like Baldi
They are related to Dicynodont.

Does this mean that the function of tusks in Placerias (a smaller genus of dicynodonts) wasn't for digging burrows either? Digging is clearly the function attributed to the smaller, but homologous tusks in Placerias as shown in Walking with Dinosaurs (EP1). I'm not convinced by the elimination of that hypothetical role you do here.
Some dicyondonts do seemed to have used them for a burrowing lifestyle. However, the size of the tusks of Placerias were sexually dimorphic, so their function was likely for display/combat. Its "tusks" were actually an outgrowth of the maxilla which had replaced the tusks of its smaller ancestors, although some Placerias individuals still had vestigial remnants of the true tusks. In any event, Tiarajudens's sabers lack the tooth wear that would have been produced by regularly digging with them.
@@chimerasuchus Sexual dimorphism isn't incompatible with a dual role. One might even surmise that longer tusks might have been selected secondarily for combat. Thus, the female (if you believe longer tusks are poorly suited for burrowing) could have been the partner in a pair that was more specifically involved with digging tunnels. Evolution of dual roles is not uncommon, you know, in animal characteristics.
@@chimerasuchus I sort of recall you mentioned that only one partial cranium of a Tiarajudens had ever been found. Hardly a basis for sweeping generalizations, don't you think? Unless I misunderstood that sentence ...
It's pronounced (tea-AIR-uh-ZHOO-dens)
Preach, Grammar King, preach! Actually, it's "tie-ah-rah-jew-dense"
@@posticusmaximus1739 Either or.
Your animals are focused in closest to crocodiles, birds, and mammals?
All crocodiles are equally close to it.
All birds are equally close to it.
All mammals are equally close to it
Anomacephelus was just a female bruh
I really like your channel but please, don't call every not mammalian synapsid a "proto-mammals".
Synapsid was an evolutionary tree, mammals are just the result of one of its branch, mammals are never been the "final purpose" of synapsid evolution; if mammals are the only synapsids alive today is for a mere chance
For some reason I thought this about jews wearing tiaras.
Must be a terribly rAYyciss white supreme or something idk why you'd be thinking about the chosen people
Even though they were herbiverous proto-mammals I wouldn't pet one. Rather like cuddling an African buffalo, notorious for their cranky persona!lity
never use AI again.
I wasn't using AI before. It was just a different narrator.
Lol
