Tiarajudens: Saber-Toothed Permian Proto-Mammal

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.

[@cabinessence_timely_hello]

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"

[@danilodesouza6461]

English speakers never seem to get our J right

[@raminagrobis6112]

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.

[@cabinessence_timely_hello]

@@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.

[@raminagrobis6112]

@@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.

[@cabinessence_timely_hello]

@@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).

[@raminagrobis6112]

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.

[@chimerasuchus]

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.

[@raminagrobis6112]

@@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.
