I hard agree here

Everybody's gangster til the crocs start galloping.

Don't forget the giant boa that hunts the croc as well

They did one on it 3 years ago I’m pretty sure.

Quinkana, Megalania and Thylacoleo all filled different predatory niches. Thylacoleo = ambush hunter Quinkana = pursuit hunter Megalania = apex hunter

BEWARE the DROP BEARS!

Murderous Panda = Grizzly Bear. Bears are Carnivorans (the evolutionary order). Pandas are the herbivorous exception in that order.

@Sir Derpymister Someone's been watching Kung Fu Panda

Marsupial lions are actually more primitive than any living diprotodont.

There was this man whose leg was made see through by a rampaging panda

"I can't believe it's not a pouched mammal!"

"I c an't believe it's not bit me"

😂

Leo means lion. Thylaco probably means pouched. And carnifex is, of course, that pistol from the Mass Effect series.

Leo generally refers to all cats not just lions

Going on foot is better than going through the redwood in the air. *Casually flying* *And now I'm falling to the ground from a great height while simultaneously having my face clawed off* They're great mounts though

Drop bears are supposed to be a legend. So, there really used to be one.

@@HairyNumbNuts yup. I maintain that the drop bear story comes from Indigenous people having to deal with them and passing down the lore

not to be confused with the purlovia "death from below badger tank"

@@bronhaller is that Australian cryptid legend ?

Agreed Steve was my favorite

Where is steve?

I know!!! I think of him at the end of every video, hope he’s doing alright

Nice to know I wasn't the only one missing him.

@@AS-fi7hc - I know what you mean. I always mentally add his name at the end of every video.

@ninthRing - Even more appropriate!

Pretty cool taxonomic name, basically "the pouched lion executioner", gotta be the most badass marsupial in name at least. Wish we still had these guys in australia to continue to round out their ridiculous native fauna

As the most primitive of dinosaurs appear to all be carnivores or omnivores, all of your major dinosaur herbivores evolved from meat eaters.

The ones with the crazy long claws. Also… pandas went through the same thing. Bears turning herbivorous.

Please make a video of the hulitherium tomasetti aka marsupial panda it live in New Guinea .

It became vegan.

NO WAY I JUST WATCHED THEIR THERIZINOSAURS VIDEO

Mythical?!? My best friend was murdered by a drop bear! This was in Texas, and there were no other witnesses, but that's the story I'm sticking with.

The whole reason the 'drop bear' story came about is because people like you keep calling koalas "koala bears" when they aren't bears. They're koalas.

There is no such thing as a koala bear, they're just called koalas, koalas are diprotodonts, while bears are carnivorans.

Drop bears are the surviving apex predator.

@@unicornfoal I'm not going to stop calling sea horses sea horses just because they're fish.

Thycaleo can't look up. Bad for a tree climber. The aboriginal in North QLD still have oral history about them. Must been scary if 10,000 years later the story is still around.

Yes, I would like to see more on this topic.

yes! it is so hard to find decent videos and books to that topic

I don't know, man. If a rat was the size of a leopard I'm quite sure nobody would laugh if it came at them.

@@robinliesens7983 Who knows? When a dictator looks like Winnie the Pooh people still do laugh.

@@geekyprojects1353 Just on the Internet, not if they are standing infront of him and being at his mercy

Momentarily

Beavers easily chew through trees. Rodent like teeth on a large carnivore wouldn't be something I would take lightly.

The North American opossum looks rather fierce close up. From a distance, it does look like a large rat. Get up close and it is not Mickey anymore.

@@indridcold8433 Agreed -- I remember hearing someone online say how cute possums were and thinking, "Are you out of your mind?" It transpired they were in Australia, where they are kind of cuddly looking. Up here, you're absolutely right -- giant nightmare rats.

Tasmanian devils are also marsupials, so we still have some scary marsupials. Though, mind you, one of the scariest is the red kangaroo, which is capable of killing you with a kick. My parents were part of a tour group where the guides were attempting to keep a tourist away from kangaroos. Unfortunately they were calling him by the wrong name.

@@asmith8692 Imagine if kangaroos became apex predators what they would look like, what would they eat and the niche of which animals would fulfill maybe that predatory kangaroo would be a mix of a kangaroo, pangolin and wolverine and would be quadrupedal and would probably hunt a variety of prey and would be an ambush predator what do you think about it?

Scary marsupial? Have you ever tried to get a cornered opossum out of a bathroom while two beagles are going crazy?

I don't think that will happen, as apparently the eucalyptus leaves that are their exclusive diet have a natural soporific in them--the little guys are always stoned.

Never heard of Drop Bears ? LoL

@@khajiitkitten5679that’s why they haven’t killed us yet, if they sobered up we would be in big trouble

From the moment humans got here they started killing off species and will continue to do so for our entire existence.

I'd love to see them jump on their hind legs

Still survives in the phrase "one fell swoop" but that's about the only continued usage

"Fell Beast" is a term ive seen in books a lot

​@@kylemackinnon5696 especially fantasy fiction, haha

I read somewhere that aboriginal peoples only drew what they saw so it would be useful to know how old the paintings were reckoned to be.

Yes, I've heard that Australian rock paintings show several extinct species. They are also beautiful, by the way.

@@blixten2928 Yes; the aborigines caused a hell of a lot of extinctions.

the origins of the "drop bear" stories appears to be Aboriginal stories of the Thylacoeo hunting. Same with Yowies & Bunyips & all the rest - Aboriginal stories of real creatures now extinct, picked up on by whites

@@NoTaboos as have all humans. Also, that term is a slur. I understand you may not have known this but please try not to use it in future 😊

Or that one finch Darwin missed that drinks blood. The vampire ground finch. Not kidding.

​@@liammurphy2725 what's wrong?

Not a wide category for sure but still nice

@@Cornexium If you were to take an in-depth look at the Australian fossil record then you might possibly change your mind on the category size.

@@kenattwood8060 Australian fossil record is indeed big especially for more recent megafauna however you gotta put it into context. How much does prehistoric Australian mammals make up of the general species diversity of prehistoric Earth starting from the evolution of proto-mammals?

One of my favourite prehistoric mammals, PERIOD.

@@Cornexium This is actually irrelevant as prehistoric Australian fossils make up 100% of the general species diversity of prehistoric Australia.... We are discussing localised evolution after all.

too bad you think they are useless :( You guys have marsupials, and they keep your yard free of pests. yet, you treat them like rats.

Invite them in. Make snacks. Make a party of it. (avoid alcohol, opossums are pretty crazy when they drink.)

@@chaosgoettin you know little.

@@benpuljak2304 but more than you, it seems.

They were hypercarnivores. Wombats are herbivores. Carnivorous animals do really nasty poos.

On the other hand the lizards were the size of crocodiles

@@mikewilson858 Yes, megalania. 20 feet Komodo-like lizard.

Thilocine was definitely more dangerous than a dog, they can open there jaw 180 degreess

Hence venom?

@@mikewilson858 I know you’re talking about the giant Komodo dragon, but my brain could only look at this and go “… you mean like a crocodile” cause they have the salt water crocodile.

To be fair, there are other relatives of the Komodo dragon still around in Australia, we just call them goannas (monitor lizards). Wikipedia even tells me we have their sister taxon still around, the lace monitor, and they're also apex predators. So we probably don't need to go that far to recreate the biosphere of pre-Indigenous-inhabitation Australia 😛

@@PurpleShift42 But still, none of those are as big as the Komodo dragon or would be able to do the same stuff. And yeah, Komodo dragons are technically a type of goanna.

Personally if I binge-watch more than like 3 of these episodes I start to feel sleepy because of the calmness of their voices, which is why whenever I'm sick I take my meds and snuggle up in bed to binge-watch them until I fall asleep, it's become a tradition for me now to the point that even watching these videos makes me feel better even without me being sick lol

like wolverine being pinned against a bear?

"That could rip a man apart"!

And let's not forget the infamously baby-eating dingos (poor Lindy Chamberlain)

@@PurpleShift42 true, though dingos are almost never encountered in most suburban areas

nothing special really.

@@Circuit7Active How is a big cat sized marsupial, evolved from placid herbivores and capable of taking down large prey with it's front teeth not awesome ?

@@infinitemonkey917 - It is most definitely awsome!

Squirrels eat bird's eggs now. Maybe not a huge stretch.

​@@sneeringimperialist6667 well, as Ian Malcolm in Jurassic Park he once said "life finds a way".😉😉😉😉

Most rodent species are already omnivorous, so it won't be particularly difficult for at least one of them to transition into full carnivory at some point in the future anyway

@@ekosubandie2094 Already Dougal Dixon in 1981 with his Falanx: "Amphimorphodus cynomorphus" (descendants of the rats that cover the lifestyle of the wolves) had thought about it, I only made a variation with another type of rodent.

Does anyone know the example of a carnivore transitioning into a herbivore? 😅

Is there is something opposite of that, from a simple predator to a large dominant herbivore 😅

​@@tijanamilenkovic3425 Well... Sauropods

Thylacines are Dasyuromorphia. Thylacoleo are Vombatiformes.

Aye

Motion forwarded, motion carried. The aye's have it....

Dingos are considered small to medium sized. This was a video about large predators and in the time since the decline of the thyla, something should have taken it’s place as the apex large predator. But outside of humans, there are no large predators on Australia.

@@Ashtari large terrestrial predators that is - Australia does have large aquatic predators. Saltwater Crocodiles, various sharks and rays, cetaceans, various predatory fishes. But yes, modern Australia lacks large land predators, other than humans and the Dingo. I do wonder what will evolve in the future to fill this open niche - perhaps a giant dasyurid? or a predatory kangaroo? fully terrestrial crocodiles? or predatory emus?

@@fubberpish3614 As harsh as the Australian climate is combined with the appearance of modern humans, we may actually never see a large land predator take the niche. We are seeing this trend around the world, where large apex land predators are in decline where ever modern humans exist, unless said humans go out of their ways to bolster the populations. Or in the case of the Brown bear it's also a generalist that can survive on humanity's refuse.

Yeah! I know little bits and bobs about this but I'd love to know more. I think that would make a great episode.

This applies to ancient humans too! So "animals" works just fine here

This is a fantastic idea! Bring 'em on!

@@iamblackthorne who is laughing now, dolphins?

@@ralsim5308 oh definitely.

@@Kayclau also how about marsupial seal, marsupial whale, marsupial dolphin or marsupial sea cow just imagine a fully marine marsupial and so many opportunities this kind of animal would have for its lifestyle

ah nothing like symbolic recognition without any substantive change to real injustice

@@duskpede5146 yeah that’s true we still have a long way to go, 💕

would have been nice if they also recognised how connected to the eco-system the Indigenous people were & how they kept everything in perfect balance without other apex predators present! That's never been seen anywhere else in the world & presumably took a LOT of skill

​@Duskpede what is PBS eons supposed to do about centuries-spanning colonialism

@@duskpede5146 recognition is the first step lol we'll get there eventually

This is exactly it. I think people are still bothered by the fact that there could exist a place during that time that didn't have mammalian apex predators, which I think stems from this deeply held belief that mammals are somehow inherently superior to reptiles or birds. Thylacoleo is an impressive creature for sure, but it's not big enough to be the apex predator when the largest game are things like Diprotodon and gigantic Kangaroos. You know what was more than big enough though? The giant monitor lizard and blade toothed land crocodiles. It bugs me that people can conceive of Australia's isolation being the reason for something like the marsupial lion existing, but can't seem to truly conceive of it's isolation also meaning that mammals never reached the spot of top predator.

In fairness people do accept mammals aren't always the apex predator, that thinking apparently just ends with the dinosaurs. As though we somehow reached a point where mammals were too big to fail. Maybe we did, but Australian mammals clearly never got that far. That's the part people can't seem to wrap their heads around.

@@ZombieBarioth well said

@@seanmckelvey6618 yep!

@@seanmckelvey6618 I think it is simply because mammal's superior thermoregulatory ability means that they can be more active terrestrial hunters than reptiles. Although monitor's unique among lizards ability to breathe while running does mean they can be more active than other reptiles and marsupials do tend to have lower metabolisms, hence lower activity levels. But lizards and crocodiles generally eat less frequently and move around less than their mammalian equivalents. Australia losing its placental mammals does clearly change things, though. And reptiles may have beat mammals to many of those niches.

Its teeth would tell us that. Looks like it doesn’t really have crushing molars like most omnivores, only cutting teeth for eating meat

Totally wrong direction, absolutely a hypercarnivore.

Just remember, there are many local variants of the Mulleted Bogan. They really are quite common, e.g. in the Valley at 3am on Friday night/Saturday morning

Not really, wombats are more closely related to cuscuses and kangaroos than to marsupial lions.
