Litopterns: South American Horse Camels

South America's extinct megafauna really is fascinating and shame that they're all gone

[@CarlosHenriqueXavierEndo]

Like all bad things that happen in South America, this mass extinction was caused by the North.

[@rextexan4727]

That and Australia's too

[@Afrologist]

I'm just glad Africa's ecosystem has stayed mostly intact from the late Pleistocene. Would've been a shame to have zero perspective of what the world looked like during before the Younger Dryas.

[@MybeautifulandamazingPrincess]

That happened because Humanity had turned out so sinful and corrupted by Satan at that point, that God had to reset creation with the flood. That's why all those animals went extinct. Only animals we have today were in the Ark

[@Tsotha]

I've been fascinated by the topic ever since reading a Danish comic book from the 1970's about two private detectives, who in one story arc go to an undiscovered South American plateau to solve a case and there they encounter a lost world full of wildlife extinct elsewhere. Including a macrauchenia and a thylacosmilus. (the marsupial sabretooth cat!) The former is of course depicted with a short trunk.

[@hatsudopia5085]

Extinct mammals are so cool they deserve more love.

[@rl9217]

(Prehistoric South America) Macruechenia: I’m stuck in the middle of this island continent with those two! Oh, why must every 11 minutes of my life be filled with misery?! Why?! Doedicurus: Oh cheer up, Mac! It could be worse! Megatherium: Yeah, you could be bald and have a big nose! Macruechenia: …

1:55 - 2:02 Wasn't aware Alamosaurus survived into the Cenozoic. Jokes aside, I do enjoy videos on prehistoric animals I've never heard of, even though I'm a dinosaur guy.

[@dr.polaris6423]

Thanks, I brought up Alamosaurus as an example of the Late Cretaceous interchange with North America that continued into the Paleocene.

reminds me of how in English the first people to see giraffes called them 'camelopards' because they thought they were magic hybrids between a camel and a leopard

"Which is the only member of the clade to have images online" Imma need to change that

[@posticusmaximus1739]

Should do some series to cover the stem-bird maniraptorans to complement the early bird series you've done.

[@gattycroc8073]

besides Macrauchnia's appearing in Walking with Beast as well as a background character in the Ice Age movies Litopterns are very underrated in terms of pop culture appearances. sure, we had Theosodon in Life On are Planet but there are just such a fascinating group of herbivorous mammals. if only they survived long enough to get and Inca sculp like the ones you see of llamas in order for us to get a better picture of them.

[@DinoLover4242]

When will you do cryptid videos again?

[@UnwantedGhost1-anz25]

I don't want to imagine what would have happened to Australia if a land bridge was formed to connect Asia by Sumatra and Java during the Pliestocene. Like when Central America appeared.

[@CJ-BZ]

itd be like whats going on in modern times, but over millennia

[@ekosubandie2094]

The island of Sulawesi is the closest thing you can get that kind of scenario albeit on much lesser extent than what happened to South America

[@baneofbanes]

Australia would become dominated by Asian wildlife. There may be a few marsupials that hang on in certain niches, but most would’ve gone extinct.

[@TheFoshaMan]

4:35 Might be wrong but according to the wiki, they're called "Protolipterna" not "Prolipterna" tho... to be more specific "Protolipterna ellipsodontoides" I think Julia spelled the name wrong tho

I wonder if Colossal will somehow find ancient DNA from South America to try and "resurrecting" some extinct species later on?

[@bradenhoefert2109]

But what living species would you use to give birth to them? They have no living close relatives.

[@Ektor-yj4pu]

@bradenhoefert2109 Camels for the big camel-like herbivores of this video.

[@Ektor-yj4pu]

No, it would be populated by many "alien" species like Australia.

Macrauchenids and toxodons going extint at the end of the pleistocene by humans/climate change makes sense in my head. But what about Neolicaphrium? Shouldnt it have plenty of habitat in the south american holocene? Why did similar rodents and deer survive but not this boy? Damn, now i will be obsesed with this

[@Eye_Exist]

rafting hypothesis is the worst level of nonsense ever invented. it only proves these people have absolutely no idea how difficult ocean traveling is.

[@istvansipos9940]

life forms raft. Sadly, no 1000 mile test run possible in any lab. But we do know that they raft. Any better alternative? Based on something what we DO know?

[@Eye_Exist]

@@istvansipos9940 life is known to raft short distances. there's no reasonable evidence which suggests life could raft +1000 kilometers on any type of free floating body and survive. we DON'T know this and all the known oceanic travel facts speak against it thus dismissing it as a bad idea doesn't require an alternative hypothesis or evidence. ideas need to prove themselves to become considerable, not the other way around.

[@istvansipos9940]

@@Eye_Exist animals moved somehow. rafting is possible. you cannot test any extreme cases of rafting, and you don't even try to suggest any alternative. Your example shows perfectly and exactly why the current explanation is rafting. And it remains an explanation, unless mankind finds a better one. Or at least an equal one. IDM either way. Find an ancient animal teleporting machine, and I'll find it just as interesting as the current idea of extreme rafting. you NOT understanding this reasoning will not really affect anybody except you.

[@Eye_Exist]

@@istvansipos9940 choosing a bad explanation in the lack of any good explanations doesn't make it any better or plausible. a scientific mind is willing to admit this and declare that we simply do not know at the moment. pushing nonsense as considerable explanation in the obsession of having an explanation for everything and with the mentality that others must prove them wrong before them having to prove them right is just that, utter bollocks. if i'm the only one who sees this then i'll take it.

[@obiwahndagobah9543]

Well somehow there must be an explanation for the fact that hoatzins, monkeys and caviomorph rodents immigrated from Africa, but nothing else did. Somehow it has to do with traits of these animal groups that are not present in others. Or freak events like tsunamis transporting these rafts rather fast from one to the other side of the Atlantic, when it was much smaller.

[@RodisyourGodnow]

I love the ice age videos ❤

[@LoLMasterManiac]

I suspect that many of these animals went extinct due to human predation.
