I honestly still feel that the depiction at the end is somewhat inaccurate, Given that Phorusrhacids had evolved to become fierce intelligent predators in their own right it so unlikely that they’ve been outcompeted by mammalian carnivorous when the birds are more than capable of fending off against them or even as a group for that matter. And not to mention the fact that based on findings of smaller relatives surviving up to the later late Pleistocene, I feel that climate change had more to do with this then this outdated cliche. Terror birds depicted in the series in my opinion should deserve better than this.
You're almost certainly correct. Phorusrhacids crossed into North America and survived for millions of years with all the other large mammal predators. From California to Florida, coast to coast. Big mistake by the writers and editors. We still don't know a lot about terror birds; most of the fossils of the larger ones are incomplete and fragmentary. We still don't know for sure how they hunted and what they ate. They may not have been apex predators. They may have hunted smaller animals or had a niche role like scavenging so they wouldn't have to compete with the other large predators.
@@krismichael1633 Titanis was the largest predator of it's time and was really 4 times larger than Smilodon gracilis and it was also larger than homotherium and Xenosmilus , so Titanis was the apex predator of it's region , likely hunting horses, ground sloths and the smaller rodents which would have also lived there .
@@Xbox-with_extrasteps Based on what fossil evidence?
@@krismichael1633 Based on evidence found in the area where Titanis lived and also based on assumptions made from terror birds which lived in South America , and since those hunted ground sloths and notoungulate then Titanis was well equiped to take down these animals. And the part of it being an apex predator, well Titanis was larger and heavier than all the carnivores it shared it's area with and the only reason why they evolved larger sizes was because the phorusrachids went extinct and it wasn't the cause for their extinction .
@@Xbox-with_extrasteps What evidence in areas Titanis lived? You need to post links. What evidence they hunted sloths and notoungulates? It wasn't 'equipped' to take down those animals. It could kick large rodents and small litoperns. Then rip them apart with their beaks.
But this is all speculation. Even the idea that it hunted large rodents. It could have been a vegetarian, cracking nuts and fruits. Lots of animals killed by Homotherium and Smilodon have been found. No Titanis kill sites have been found. You're simply making up fan fiction.
Titanis wasn't the only 'Big Bird'. They lived on every continent right through the end of the Pleistocene on every continent. None were 'apex predators' although some were probably predatory. In Titanis' case we have the Big Bird but no dead Sunffaluffagus...
It annoys me the narrator doesn't say what kind of terror birds they are. I believe they are suppose to be Titanis but isn't stated in the episode
Well let’s be fair they’ve been calling them Terror Birds for years just because it’s easier this way I for one call them all Terror Birds
I was thinking Kelenken
@hueyfreeman2687 kelenken was
In South America 15 million years ago....
@@aurelsmarterazo8221 Idk everything
The behind-the-scenes featurettes confirm that they're TItanis.
I'm a huge bigcat fan, but Titanis coexisted with Smilodon gracilis which were not big enough to challenge adult terror birds. However at that time there was a bigger sabertooth cat known as Xenosmilus which may have killed both terror birds and S.gracilis.
they are way too small to that and birds are WAY more maneuverable in neck movements to be able to catch the only cats that it lived with
Xenosmilus would have been able to kill S. gracilis (and actually DID, based on Xenosmilus feeding sites where the kills dragged in included S. gracilis), but when Titanis was around it was still only around Jaguar-sized (with gracilis being leopard-sized). Once Titanis went extinct Xenosmilus got bigger (tiger-sized) and briefly replaced it, only for it to go extinct from the same causes shortly afterwards (not even half a million years later), allowing S. gracilis to take over (going from 55-60kg to 100+kg) and later become S. fatalis (250-300kg, the same size as Titanis used to be).
Titanis itself started out as a leopard-sized predator in the Early Pliocene when Amphimachairodus coloradensis was around. When that thing went extinct halfway through the Pliocene it came down to Titanis or one of the smaller sabretoothed cats to get big and replace it, and the bird managed to beat the cats to it. So there was a succession of tiger-sized land predators with neck-driven cutting bites dominating North America, dying out from climatic factors, and then being replaced by a leopard-sized or Jaguar-sized predator that got bigger to fill the gap (tiger-sized Amphimachairodus and leopard-sized Titanis and Megantereon => Amphimachairodus goes extinct, tiger-sized Titanis and leopard-sized Megantereon, which then evolved into the leopard-sized Smilodon gracilis and coexisted with the Jaguar-sized Xenosmilus => Titanis goes extinct, tiger-sized Xenosmilus and leopard-sized S. gracilis => Xenosmilus goes extinct, S. gracilis gets bigger and then gets even bigger when it evolved into S. fatalis => S. fatalis killed off when humans start to dominate in North America, especially since seeing as it was specialized for warmer forested habitats and thus would have benefitted from the end of the last glacial period)
No, Xenosmilus is smaller
@@knowncoralconsumer there’s also the fact that sabertooth cats were generally more heavily built than other cat species and therefore less agile, so it’s not like they’d be able to jump on a titanis back or throat in a direct confrontation (especially when you look at how tall a titanis is compared to a smilodon gracilis). There’s also the fact that terror birds have much denser bones than the majority of other birds, so they could probably take more of a beating. Then there’s the fact there necks were well built to withstand dorsoventral stress meaning they could jab downwards with extreme force. A single well aimed jab to the head or spine and the smilodon is either dead or paralysed. Sabertooth cats were likely mostly ambush predators to begin with.
@@theotheseaeagle true that
Ugh. Not the “Smilodon wiped out Terror birds” myth again.
Yup, your 100000000% ! Correct on that,
terror birds would be more than a Match for a smilodon.
The powerful robust recurved beak with strong neck muscles, it’s robustness and Cursorial build, and feet with sickle like toe claws much like a raptor such as the well known very large utahraptor, are very formidable tools at its disposal, and would do a a whole lot of.
The fact that terror birds actually EXPANDED their range when coming into contact with the northern fauna should be evidence enough that northern predators didn't wipe them out, but I guess not...
Not to mention on their intelligence, if anything hypothetically speaking in a speculative sort of way for all we know they could had maybe lived in a group like Harris Hawks for example. This series while cool is it is should had plan out more especially on accurate depictions
@@turboZ3 that its not even one of the reason giving that they lived toguether for a considerable ammount of time so its still wrong
You made that assumption. The documentation is only covering one part of the puzzle science never ruled out.
I’ll admit, I do like how instead of fighting already, they first do a sort of display
*Can Trixie and Katya review this?*
YES PLEASE!
Trixie would actually love this content, I agree
💯%!
Omg yes please!!!
Who are they?
Trixie and Katya should definitely review this!! Trixie in her bird-loving era, sure she would get a kick out of this!
she woudn't like it tho, the whole "terror birds died because smilodon!" narrative is a big myth, they went extinct because of climate change
Still, the terror bird could put up a good fight and in some instances even killed saber tooth cats. It's just that here one bird was taken by surprise and the other decided not help, since the death of a rival is beneficial for it.
I dont think theres any evidence for that
@@brandonkey181 I mean it seems logical, since Smilodon gracilis wasn't very large compared to Titanis.
@@brandonkey181 there absolutely is evidence that titanis was the dominant predator in its environment. The presence of Titanis in the ecosystem was most likely what stopped Smilodon Gracilis from getting larger and evolving into Populator, since they only started getting bigger once Titanis had disappeared
Terror bird 1: “This pond isn’t big enough for the two of us.”
Terror bird 2: “Oh yeah? I’ll dance to that you overgrown sparrow.”
Terror bird 1: “I’m as badass a Big Bird as you are.”
Smilodon 1: “Hey, come on, Bob. Chicken for lunch.”
meanwhile, in reality:
Terror Bird: MMMM DELICIOUS FELINE FLESH
😂😂😂😂
Smilodon 2: “Okay, Nigel.”
This sequence seems kind of nonsensical. No predator would turn sideways to a potential threat.
Cats do it
South America was even more dangerous back then until around 11,000 years ago. Especially before Central America's land bridge has formed.
I will give credit to the way the terror bird fight is depicted. Rather than being shown as two males pecking each other to death, the fight is, for the most part, a series of displays, meant to intimidate the rival without causing bloodshed. This is how infraspecific competition often occurs in the real world.
I know dinosaurs existed and we have fossils but how could people know they danced? Is their scientific record of this? Genuinely curious
It's more of an estimated guess. We compare extinct animal to living ones to fill in the blanks. In this case, birds. Some animals do leave tracks that give us an idea of what their dances were like. All this helps to a clearer picture of these animals' life styles.
We actually have fossil evidences of mating dances in non-avian theropods in the form of footprints. Pretty amazing
most info here is based on the shoebill.
@@draw-a-saurus Is that the machine gun bird? They do dances like this? Love your name btw.
Should have added in case you didn't know. These guys aren't 'dinosaur-dinosaurs'. The ones that were around with T-rex, stegosaurus and the rest. It's descended from the birds that survived the mass extinction that wiped out the rest. It's ancestors could fly but it grew so big it became flightless. Like an ostrich. It lived millions of years afterwards during the age of mammals. A hint is that sabre-tooth cats didn't co-exist with the non-bird dinosaurs.
The documentary may not be that good , but you can't deny that the animation is absolutely beautiful
Ok Morgan stop the phorusrhacid slander the Machairodontinae did not drive them to extinction 😒
"I like ya cut G"
"Eoowooooeeigh"
The Fight Dance Is Very Good
This feels like it was originally intended to be a _courtship_ ritual (because that's what birds who do the whole "synchronized dance" thing use it for) and then one of the higher ups changed the narrative at the last minute to make it more "badass." Which is then subverted by perpetuating the "sabre-tooths drove terror birds to extinction" myth.
Ok that looks alot like an raptor or something. That an freaking dinosaur!
This is a very interesting ritual.
This was written during the writers strike and was never fact checked. The idea could have been so much better and well executed...
Red raptor writes should review this documentary
All in due time my friend
Bring Trixie and katya back pls!!!
Man this documentary is filled with inacuracies , even the model of the terrorbird is wrong
All these people in here clearly didn't pay attention to the narration. The documentary doesn't say the smilodon was THEE only reason the terror birds went extinct, it said they were "one of the reasons" meaning there were multiple others.
Agreed
The problem is that smilodon was not involved in the extinction of the terror birds at all
Magnificent animals. We should bring them back.
No Are you crazy!?😡
The one birds like "see ya "😂
dinosaurs of that time
This was really well made and imagined
Always watch your back even when your beefing.
Can we all agree a 10 foot predatory bird that walks on the ground is Terrifying!
Omg trixie and katya has written all over this ahdhjfjff
The terror birds that had to deal those cats weighed twice as much as them an were very B I G an deadly why is it so small
Actually Titanis outweighted Smilodon gracilis, it's unlikely for the cat to target adult terrorist birds
You'd think if they could afford morgan freeman they'd have better cgi...maybe prehistoric planet spoiled us
BRO THE CGI IS ALRIGHT YES PRP DID SPOIL YOU
They look like unfinished assets, its not being spoiled is noticing the lack of quality
@@spinosaurusstrikerLooks just fine to me.
@@psychokinrazalon well i hope you don't work as a cgi supervisor sjjsjsj
@@spinosaurusstrikerDo you?
This is The embodiment of “who’s gonna tell him?”
(Assuming this is Titanis Walleri, that means it would more likely be The bird hunting The cat, lol)
wow that was fascinating, and terrifying!
“You speak like a poet but you punch like one too”. Willie the terror bird
It's like Jurassic Fight Club all over again.
Idk about this. Dancing instead of fighting seems highly unlikely. I wonder who came up with this
It’s more like showing off how fit they are without actually harming one another think like a cobra spreading its hood or gorilla pounding its chest .
Chocobo 👀
final fantasy chocobo real life
I don't know how accurate this feeling is; towards the end of their reign, this is what the mighty Tyrannosaurus Rex may have looked like. A twenty five foot long flightless bird of prey.
It’s a shame we missed out on seeing so many interesting and gigantic creatures. 😞
If we'd co-existed, you would've seen it right before it killed you, though.
@@FGC-ku4ez lol. Still be worth it to see it up close.
@@FGC-ku4ezTerror birds are only a couple steps up from cassowarys.
@@dannyhernandez265 I mean, I agree! Lol 😆
that's Chocobo from Final Fantasy
This cgi is really well done
Yea it is
Hello. Is it allowed to use these videos with Farsi voiceover to convey awareness and knowledge on TH-cam?
А lot of unnecessary attacks and shouting. Look at the battles of modern cassowaries: a couple of poses, a sharp throw, a series of exchanges of blows accompanied by a terrifying hiss, the loser quickly runs away, and that’s it
"The two begin a ritual display, assessing the others' strength while showing off their own."
Yeah, uh, that is pretty blatantly a MATING DANCE more than anything.
like a chocobu in final fantasy
Who's going to be the first to back down... Dude this is mating behavior not fighting
This is so stupid. Like saying a housecat can kill an eagle.
From the cartoonish roar animation to the visuals, this looks so unnatural / unrealistic to me 🤷🏽
Who wants Terror Birds in a JWE2 DLC?
How terrifying
Cool move
How do they know this ain't no way they did all that instead of just scraping it out
Last true dinosaur!
How do you know these hybrid eagle/ostrich is displaying to each other like that?
It looks better than the damn Flintstones but animation ain't there yet.
1:21 how do we know these creatures exhibited these particular behaviors?
They are related to modern tinamoas they exbit featured like this, so the creators just tried to adapt it
Average redwoods experience on ark
We're lucky they didn't notice us!
Birds of Prey (order Falconiformes) are a very large and diverse order of birds, filling many ecological niches, there are only nine extant families of birds of prey, Cariamidae (Seriemas), Sagittariidae (Secretarybird and Fossil Relatives), Aquilidae (Eagles), Accipitridae (Hawks, Buzzards, Harriers, and Kites), Pandionidae (Ospreys), Aegypiidae (Old World Vultures), Caracaridae (Caracaras), Falconidae (Falcons, Kestrels, Hobbies, Falconets, and Montanaguila), and Cathartidae (New World Vultures), there are also extinct families of birds of prey like the well known brontornithids (family Brontornithidae), the dromornithids (family Dromornithidae), the gastornithids (family Gastornithidae), the terror birds (family Phorusrhacidae), and the teratorns (family Teratornithidae).
But how do they know about the ritual? Who observed it happen?
Sometimes I think this whole series is a Remake or Reboot to ,,Walking with series''-trilogy
meu deus que realista esta ave do terror parabems pelo trabalho😱😱😱
My best is Mr Morgan
The newest scientific revelation says, they wore sailor suits while dancing.

That's a chocobo fr
Unbelievable to watch
The real Chocobo
Phorusrhacos Logissimus or Titanis Walleri?
terror birds are so big better than cassowary
Just a normal day in Britain
Have I found yoooooooou
Flightless biiiiiiiiiiiiiiiiiird
And they know how they act lol complete guess
how do they even know that though. like from the fossils
Bird behavior in modern times
In this particular case, it's looking at modern animals and filling in the gaps. Modern birds do elaborate displays for social interactions, so it's a logical conclusion that terror birds likely did the same, especially since terror birds are closely related to extent birds like Seriemia
@@OmegaPictures318 it one in Australia.. causuway I believe
Makes the exact same sound as the Doedicurus… how lazy do you have to be 🤦

Little credible.
so easy
Nonsense
You can tell for sure they didn’t hiss like that! Which bird does it??! 🙄
when do they hiss and what is your problem with it
Look up Cassowaries and their sounds.
@SwiftSwimmingShark: rubbish, that's just one point of view, and nothing more ....
Okay how much BS was that terror bird dance?
😎
Uggggh the title of the video, from millions from - terrible use of English, please fix this.
The title should be „How Terror Birds could have Fought for Territory“
Нелепая постановка)
proof?
how the f do you know this thing actualy existed and looked exact like this and did dancing
The dancing is just speculative, everything else is not that difficult because we have phisica evidence, still the model they used in this documentary is wrong
The dance is speculative . But there are specimens of phorusrachids which have been found . And somehow this horse shit documentary still gets the models wrong
