Thylacosmilus: The Sabertooth With A Pouch

This carnivore had the fangs of a Sabertooth Cat, but the pouch of a Koala. It’s a bit of a weirdo. Support Animalogic & Paleologic by signing up for your FREE trial to Wondrium here: ow.ly/GXkW30sb73i Your brain will love it!

2:01 Macrauchenia is actually a meridiungulate, closer to Toxodon than to the llama. Otherwise, great vid! There's even a hypothesis that Thylie was an anteater-type animal, what are your thoughts on that? Can't wait to see what's next!

[@dondragmer2412]

Do you mean Thylacosmilus used those sabers to tear into ant nests, maybe also termite mounds? Seems to me claws would have been better suited for that.

People underestimate marsupials. Just cuz they have slow metabolisms doesn’t mean they aren’t capable of impressive explosive activity. One time I saw a possum blast out from under my house running faster than a rabbit. The Possum ran down a garbage truck going full speed and jumped 4 feet off the ground and landed in the back of the truck and started feasting it was crazy

[@kevinnorwood8782]

This sabretooth has always seemed so weird to me because of the sheaths for his sabers. Smilodon doesn't have those sheaths in its lower jaw, so I couldn't really picture how Thylacosmilus would be able to get those sabers into any prey items because I kept seeing those sheaths getting in the way.

[@sirsanti8408]

Why would the sheaths get in the way?

[@chir0pter]

They could open their jaws extraordinarily wide, even wider than smilodon. They probably opened wide and stabbed down with strong neck muscles

What if their tooth is entirely not for eating or hunting as it mentions that the teeth is fragile and have weak jaw power. What if it for display? Some of the largest canine nowdays is belong to herbivore animals such as hippopotamus and gelada baboon.

[@munstrumridcully]

Are the saber-toothed cat marsupials the ones that are also known as marsupial lion? Or was that a separate species that was also a cat-like marsupial?

[@elmono6299]

Separate species. Unlike the sabertooth marsupial, the marsupial lion had rodent like incisors (front teeth) similar to a rat, a rabbit, or a kangaroo in which gave them the advantage for a powerful bite that can break bone and chop flesh easily.

[@munstrumridcully]

@@elmono6299 thank you, I wasn't sure cuz I was like there really were two separate genus or species of marsupial cat like things? LOL I appreciate the info :-)

[@benbreeck3363]

4:06 While Machairodont Felids like Smilodon, Dinofelis, and Homotherium showed bare saberteeth, Barburofelids did position their sabers against their lower cheeks, just like Thylacosmilus.

[@fabricio-agrippa-zarate]

When I was a teenager, I was writing a light novel featuring humanized forms of most ice age animals: from smilodons, mammoths, and short-faced bears, to giant armadillos and sloths. The story is about how the empire of the smilodons, called Gaolyrs in the story, conquered the land that would correspond to South America, and the kingdoms and tribes from there, the most important being the kingdom of the Toxonites, which would correspond to the mixotoxidons. The Gaolyr empire brought within their forces other "peoples", like the Lupians (wolves) and Morlians (mammoths). I might continue with a trilogy at some point.

[@erichtomanek4739]

You are WRONG. Llamas/camels evolved in North America and were only able to invade South America when the Panama isthmus was formed about 3 million years ago. The picture you showed was Macrauchenia, a species of Litoptern once found only in South America.

[@sunnypeach1328]

I suggested Hummingbirds on a previous episode and a lot of people agreed! I'm surprised Animalogic hasn't done an episode on them yet; really hope you do! If you want to see it too you can suggest it too in the comments :)

[@fiberpoet6250]

Also some scientists think that sabertooth in cats is a gene that pops in cycles within felines. Sometimes house cats get very long front fangs and we make memes of vampire kitty with them lolz. Also I believe the clouded leopards are on the evolutionary path to become the next sabertooth cats

[@samrizzardi2213]

Excellent work on Thylacosmilus atrox (Marsupial Sabertooth cat) my friend! I read about it in my book called: National Geographic book of Prehistoric Mammals by Alan Turner, Illustrations by Marcio Antón and introduction by Richard L. Cifelli. Truly a one of a kind book too. And also one of the most deadliest marsupial predators in Prehistory.

[@kunalnandurkar2364]

Mam in video at the duration of 2.03 you said Lama's are twice the size of modern day relative but at someone's video I learnt that the prescribed animal having neck like camel and trunk like elephant is actually one of closest relative to Rhinos or Horses.

[@TunaFreeDolphinMeat]

Its markings look like The Thylacine (Thylacinus cynocephalus: dog-headed pouched-dog). Better known as the now extinct Tasmanian Tiger.

[@idraote]

Are we sure about the "canine pouches"? In time they would become very dirty and filled with debris that would cause inflammation and possibly infections.

[@jacklantern7479]

What a badass marsupial! Too bad we missed it by a few million years lol

[@flamencoprof]

To me, the main question is: "Why did they have the lower jaw extension to match the upper sabre teeth?".

[@seandewar47]

I saw an Art post from HodariNundu that suggested a Sloth Bear-like lifestyle and I honestly Adore this idea! It makes this already bizarre animal even more bizarre! And considering how large Sloth bears get, it's not impossible that a Thylacosmilus could sustain itself in this fashion.

[@bunnygirl2448]

You say their teeth were sheathed. Yet I don’t see how this would look in any of the illustrations. This leaves me a bit confused; were they sheathed inside the bone of the lower jaw, or in pouches of skin along the sides?

[@alceratops6853]

2:51 I'm gonna be honest, I thought the animal was taking a piss with how that blade of grass moved 😂😂😂😂

[@samwill7259]

It really does just blow my mind that we are basically living in the "last age" of the marsupials. Not that they're all going to die out anytime soon (hopefully). But I mean like, in a geological sense. This entire different category of mammals that used to be as diverse and omnipresent as the placental mammals just got widdled away and outcompeted a tiny bit at a time until only a single species of possum and the denizens of australia and surrounding islands remained. Like we as a species came in to see a snapshot of the tail end of a great biological dynasty.

[@beastephenson7970]

Can we do a crossover with second nature and palaeontology episode about the amount of animals that have evolved sabre teeth? I mean there have been so many random animals over pre history that have independently evolved this feature

[@krankarvolund7771]

I don't want to contest paleontologists, but.... how a scavenger find soft organs? That would be the first thing a predator eat, no? ^^'

[@krankarvolund7771]

[@tonyevans9999]

It would be interesting to explore what's known regarding the jaw articulation. It is difficult to picture the animal getting anything past those incisors without a considerable gape, hinted at in footage of the thylacine. The soft organ scavenger hypothesis is an attractive one.

[@dont-hurt-me2519]

How about an animal from the Palaeozoic Era such as the stem-mammal: Estemmenosuchus?

[@CJ-BZ]

2:00 pictured on the right is a Macrauchenia, a species of litopern nowhere even remotely related to llamas & camelids. Meridiungulates were there own very unique group of convergently evolved South American ungulates.

[@dondragmer2412]

Does she mean 15 centimeters (6 inches) long for the section extended outside of the skull? Counting the saber length inside the skull it looks about twice as long as that. Even the skull she holds looks like it has a saber longer than 6 inches.

2:04 -There might have been giant llamas, but that is a recreation of Macraurchenia to the right, wich was not related to llamas. 2:26 -The 'Great American Interchange' began 2.5 mya. 4:13 -We don't know if sabertoothed cats had displayed canines or had them in concealed by lips. 5:26 - Smilodon kind of famously had a relatively weak bite, compared to pantherines. Evidence suggests it used it's neck mucles to sink it's massive canines into the neck of it's pray.

[@Deeer69420]

Smilodon didn’t bite bones, their Sabre teeth were too fragile so they used them to slice instead

[@rjung_ch]

Love the drawings from Danielle

[@lauriepenner350]

The whole sheath arrangement seems super awkward though. It only works if your teeth are perfectly aligned. Any animals with an under or overbite would do themselves some serious damage.

Smilodon and its relatives had weak jaws too, and did not bite into bone.

[@briandigiovanni6159]

They have outward facing eyes and a postorbital bar which isn't typically found in carnivores. Is it possible they were actually herbivores or at least omnivores? And the long canines being more for defense?

[@caspion1647]

There was actually a really interesting article about this called: "Seeing through the eyes of the sabertooth Thylacosmilus atrox (Metatheria, Sparassodonta)" also isotopic analysis already showed that the animal definitely fed on notoungulates (and likely hunted them too).

[@dondragmer2412]

She must have made the mistake about Macrauchenia being a prehistoric llama relative because its original discoverers thought it actually was a type of llama or early camelid.

[@dondragmer2412]

True. It was actually in a separate, not closely related order known as the Litopterna. Convergent evolution.

The music is _always_ great on this channel, but there's something extra special about today's that caught my ear a few times- I even had to rewind to catch what had been said once because I had been listening to the music and didn't notice the narration pick back up again! That's my fault, though- the background music is appropriately subdued when the host speaks and only picks up between narrative points. To whoever chose and edited the music: very well done! 👏🏼👏🏼👏🏼😊

[@dondragmer2412]

At 2:02 to 2:04 there is an error on the prehistoric llama relative. That is not a prehistoric giant llama relative. It is a Macrauchenia, a notoungulate, not even in the same order as that in which llamas are as they are ungulates.

[@dondragmer2412]

Correcting myself, Macrauchenia was in the order Litopterna, within the superorder Meridiungulata, and related to the order Notoungulata, of which Toxodon was a member. All these taxa are a kind of hodgepodge, the superorder Meridiungulata being itself something of a mixed bag, so future fossil finds and anatomical research on them may result in some changes.
