About 5 million years ago, a new predator made its way from the south and onto the coastal plains of North America. It was a giant, flightless, carnivorous bird and came to be known by one of the coolest and most richly earned nicknames in all of paleontology: the terror bird.
Correction! Thanks to Ben Creisler for pointing out that at 4:10, we mixed up the Paleogene Period with the Neogene Period. We regret the error and hope you still find these birds as terrifying as we do.
Thanks to Julio Lacerda and Studio 252mya for the Titanis illustration. You can find more of Julio's work here: 252mya.com/gallery/julio-lacerda

You were killed by a Lvl.150 Terror bird

Is Ark similar to The Stomping Lands game?
yes, kinda, but the stomping lands is dead and no longer exists.
pffft, trust me, when the new tlc pass arrives, im sure the terror bird will be amazing, and will even look better!

And when its not terror birds its probably Ichthyornis
The sole reason I generally avoid the boreal forest biomes.
Gotta love how popular these are for being vicious and scary killers - but put even a single feather on a raptor or t.rex and they're instantly "too fluffy and cute to be taken seriously"...
We can blame Hollywood for that.
@@@XMIR10C Well, to be perfectly accurate they had proto-feathers. Not hooked into a plane like most modern feathers, but fluff for keeping warm etc. Like ostriches!
And if you find Chinese variations of T-Rex with feathers then the American ones almost certainly had them too. All I need really is a sauropod with feathers and I'll be happy.
Man, I can't wait for the first movie to just go all out with this, after nearly a century of drably colored reptiles posing as dinosaurs in every movie. The more wrong paleontologists can make JP the better it is. Always hated that movie. Personally I think Steven Spielberg should receive a lifetime ban from making any movies with animals in them at all. Dude is clueless.
@@politicallycorrectredskin796 They had bones of the archaeopteryx. They had at least some idea that at least coelosaurian therapods had feathers. What did they do? Made them emaciated and scaly. I for one think raptors looked awesome with feathers, the way they slicked back and looked like they could cut you. JP is a cinematic masterpiece, but their dinosaur adaptations are a crime against humanity.
Fishslap 33
To be fair, evidence was less solid at the time, and the plot for the movie was that they were specifically modified to be more... “entertaining” to the public eye. So, more dragon like: no feathers, big teeth, you get the drill

Dinosaurs didn't give up quickly, just look at these guys.

KhaanMan66 lol.
Yeah these terror birds remind me forcibly of tyrannosauridae.
The way I see it, terror birds were dinosaurs that took over from the likes of Velociraptor and other meat eating theropods. The legs and feet alone are proof enough it was a dinosaur even if it itsn't explicitly called a dinosaur. But since it was one of the birds that are classified as Aves, and with the fact that all birds today are dinosaurs in mind, I consider the terror bird to be one as well.
@Cuzeg Spiked birds existed long before tyranosaurus rex, and long before tyranosauridea family.
This group of dinosaurs is one of the earliest.

The closest living relative to the terror bird is known as the seriema, it's pretty common in parts of Brazil, Paraguay and Argentina, and it has a crazy raptor-like claw in it's feet it uses to catch small animals, their singing can be listened more than 1km of distance!
How interesting! Thanks for the tip.
To hunt one would b cool or just spot it
I'm surprised you didn't mention the Terror Bird's biggest flaw when dealing with the new North American predators; it's huge eggs it laid on the ground that were very vulnerable to attack.
MRDLT00 I assume there were scavengers in South America as well?
Thank god for that !!
It was probably more the climate change causing colder temps the birds didn't like, and also causing floral turnover causing prey extinctions. Competition during stressful times could also have impacted them. Also, Harris's hawks hunt cooperatively.
Actually for its big size it laid tiny eggs the size of those of a hummingbird.

I remember reading about terror birds as a young kid and being fascinated by how they could hunt down mustangs, as well as their impressive beak
Shoutout to the show Prehistoric Park for teaching me about this well before i first played ARK
"Ark: Survival Evolved" has instilled in me a deep burning hatred for these oversized murder chickens.
They're interesting to learn about though.
I here you bud
Once, I had just spawned in and after less than a second a pack of terror birds instantly killed me. I then spawned in again, and the same thing happened.

Tierzoo missed a huge opportunity in not mentioning these in his "Dinosaur-like builds" video.
Love that channel!
The reason they weren't mentioned is because, like dinosaurs, they have been patched out of the game.
I remember playing as a Terror Bird when the game was in beta. On Windows 3.1
culwin i remember back to when the game was a text adventure with a purple screen. get the eons reference? ;)
Praise TierZoo! He's the greatest!
So were all Terror birds lone hunters, or did some travel in packs?
Justin Trudeau Latin Kings
Well it could go either way. Some films see them as loners while others like WWB see them more as a mixture. Its all speculation at this point and looking at their modern relatives.
Birds of a terror flock togerror.
Whle most birds are solitary hunters there are some exceptions. For example the Harris Hawk. No telling which way terror birds would have gone.
This is a good point. If we look at their closest living relatives, seriemas definite forage alone. But that's because they do not necessarily scavenge a lot and they focuses mainly on small prey. But if we turn our attention to their second closest cousins, some falcons - basically the caracaras - do cooperate to take down their prey; parrots, on the other hand, are extremely social animals. My guess is that most of them are solitary hunters for the sake of being small-game hunters, but can be quite social at a carcass similar to vultures today.
I’m pretty sure this was the first PBS Eons YT video I ever saw and then I subscribed. Yay
Great episode! The host was more relaxed than he has been in previous eps. A lot of fun! Terrorific!
I love the terror birds! I saw one at the field museum exactly a week ago. Thanks!
Was it dead?
geph c ha! Fortunately yes! She appears in my video. She was also a smaller one.
Cool!
I saw one in my local duck pond the other week. It had disguised itself as a Canadian goose, but I knew its game.
Egypt Guy You may saw secretary bird, which kinda looks like smaller terror bird
I've been curious to learn more information about terror/killer birds ever since I was a child. It seems we dont know too much about them other than small tidbits. That being said, this video was very informative as an introduction to someone new to the paleontology scene.
When I scramble eggs, I leave the window open, just so other birds can see what I am capable of.
Your comment was quite funny :D
60 million years ago! Are you sure about that, because I got killed by a level 150 terror bird yesterday

At LSU we had a $100 bet/reward for whoever could find a bone from T. Walleri in Louisiana. We knew of the fossils in Texas and Florida, but we had never found any as far as we knew.

Also, go mammals!

This channel, these people.... you are all so beautiful. Thank you for making these and being here!:)
I find this period of pre-history more fascinating than the time of the dinosaurs.
these were my favourite creatures from the walking with beasts series. They are so fierce and sassy i love it
Awesome as always. Oh, yeah, the Great American Biotic Interchange, one of the main reasons my home country Mexico ranks on the top 5 megadiverse countries on Earth, located right at the frontier between the Nearctic and Neotropical biogeographic regions!
I learned about the beak tooth from TierZoo. Small hitbox, high crit rate.
Excellent video thank you so much for sharing this incredible story
Very informative and entertaining, thank you.
I would love to see a video about ancient animal migratory paths, not just the Americas but maybe the whole world, as a Series maybe?
Ditto, and for plants as well even though they usually have less eventful stories behind them that the animals. It's fascinating to see how various chance opportunities at different points in history led to the distribution of life, and then to the diversity of life when the specific chance opportunity ended and the now separated lines of the specie evolved to survive in different circumstances (or died trying).
I like the fast pace of this video while keeping the story flowing well. Good job!
Dinosaurs were like, "An asteroid killed us off? How's a big...NOPE! We're BAAACK, with more feathers!"
Ty, you were very informational and not a 20 minute video. Good work, I appreciate.
Man, this channel was such an awesome find.
i love the use of maps! thank you for that. it allows me to visualize the whole thing.
Brontornis are my favorites of the bunch because its massive beaks! Absolute beasts!
That Titanis made it for three million years in North America and only went extinct when the Ice Age kicked off is fairly impressive, honestly, especially when you consider what a different ecosystem it walked into.
Imagine a tyrannosaur using its feet to kick it's pray to death.
They're so closely related to birds, I can actually see them doing that.
4:32 - whatever that sabertooth is doing, it looks...painful.
What’s up with it’s legs
It's doing a spin. I've seen lions do it too in documentaries.
I wish we still had terror birds. I want more gigantic bird species. I'd also like a chocobo like bird that we can ride for longer than an ostrich
How have I missed these videos!? Subscriber!!
Cheers from wonderful Panama! Always lovely to see our map featured on content this great, keep up the good work!
This is my favorite Scishow channel. More of these please!
Considering the T-Rex and the Velociraptor were among the closest dinosaurian relatives to birds, we can say Phorursacidae/"terror birds" were just continuing a "family tradition": in many ways they were the closest birds to their "theropodian" roots.
The Terror Birds beak would be like a pick axe coming down on you!
This channel is the best channel, thanks for the knowledge gang!
Very passionate about educating. I love the vids. Thanks chief
Terror birds migrated to ragnorok lmao
Ark reference
On the map I play on mobile they are on some beaches and in the red woods
I truly love PBS Eons, and am grateful for all you folks do. I have two small quibbles here, though. Somehow an extra "s" crept into the middle of your pronunciation of the obsolete term Phororhacos. It's like "Fo-Ro-Rackos". But what I really don't understand is the anatomy of the saber-toothed cat in the painting at 4:34. The body is supposedly falling, upside down, yet there's one hind limb depicted as if the back half of the animal were standing upright. I mean, cats are lithe, but not that much.
I love these videos. Every time I see one in my feed I feel happy.
But could you maybe speak a little slower please?
I sometimes have trouble processing everything you say.
You bet Riana. Other people have been saying that too, so I've been trying to slow down, and we're beginning to edit the videos so the pace is a little more easygoing. It'sjustthatsometimesigetsoexcitedaboutthisstuffican'twaittotelleveryone! I hope you understand.
I love the speed! Perhaps listeners who want a slower pace could try 0.75. But personally, I think what you have now is a great pace. Once you get used to this speed, you adapt fairly quickly. OP should try this video at 0.75 and they will probably will like it. I tried it quickly and it's probably what they want.
If they make it slower then I’ll have to set the speed to 1.25. I found the pace perfect.
Maybe not necessarily speak slower but at least keeping the commas and periods to let viewers process every sentence! Speak at a pace that feels natural to you, as if you were speaking to a person instead of rushing through your teleprompter!
Some studies suggest that the ideal pace for video lectures is between 200 and 250 words per minute. REF: Guo, P. J., Kim, J., & Rubin, R. (2014, March). How video production affects student engagement: An empirical study of mooc videos. In Proceedings of the first ACM conference on Learning@ scale conference (pp. 41-50). ACM.
PBS Eons You’re so lovely! Thanks for doing what you do and making the rest of us excited about this stuff too ☺️
I would love to see an episode on discussing different processes of fossilization, including what actually happens at the molecular level!
"their time here was so short" still much longer than us tho x)
these videos bring me life
That's amazing, I had never heard of these birds before!
There was also an Australian Terror bird that existed 15 million years ago, Bullockornis planei.
Otherwise known as
'The Demon Duck of Doom' or Thunderbird.
Archeology in Australia has only really taken off in the last half century or so, and field trips have taken full advantage of the development of the beer esky and portable refrigeration.
For further proof, there was the discovery of a 7 metre long extinct genus of snake in the riverleigh deposits related to the modern python. It was named Montypythonoides riverleighensis, or ......

The Monty Python.
Thank you for all the artwork of terror birds - it really helped me get an idea for how Axe Beaks would likely move. Not that I'm much of an artist. I've just got an idea in my head that I've got to try to get down on paper. lol
Another great video!

How long will human civilization be detectable in the fossil record and how long would it have lasted if humanity had of just died out at different points in its development?
Angel Samael sounds like a great idea.
I think that all infrastructure (buildings, roads, vehicles, etc) will all have completely disappeared in a million years, but all the metals in those things would become embedded in the Earth's crust, which could be detected by intelligence beings in the far future. And given that there are more than 7.5 billion people alive today, certainly someones remains will become fossilized (we've found fossils of soft bodied animals from before the Cambrian explosion 542 million years ago). I'm afraid I don't understand the second part of your question.
I've heard somewhere that our most permanently visible trace in the geologic record will actually be all the plastic we produced.
vermeer grange 👏 👏 👏 👏 👏 👏
Most construction material - concrete, wood, brick - will vanish quite quickly in the fossil record. Metals may or may not depending on the geology/hydrology of the particular region - though whether archaeologists of the future would be able to tell they used to be part of civilization rather than just some weird ore deposits is unclear IMO. Buried plastics will last quite a long time though probably not millions of years - again the carbon-rich layers they leave may or may not be enough to identify an advanced civilization.
There will definitely be human fossils but whether there will be enough to have a good chance at recovery millions of years in the future is unclear - sure there are 7.5 billion alive today but that has only been the case for a few decades, whereas most ancient fossil species we know of spanned hundreds of thousands to millions of years.
All that said four results of human civilisation will definitely be detectable in the fossil record:
1) mass extinction & migration of species - the sudden spread of small cats, dogs, rats, horses, and certain plants around the world combined with the sudden disappearance of so many other species and rapid depletion of large fish species will definitely be noticeable in the fossil record long after we are gone.
2) Changes in plant diversity & distribution related to our massive agriculture system will be recorded in pollen traces in sediments in nearly every freshwater system on the planet.
3) nuclear power/weapons - accidents from nuclear power stations and nuclear weapons testing has significantly increased background radiation levels (though the magnitude is small) and nuclear testing sites will have detectable increases in radiation & radioactive material for millennia (though magnitude will be small).
4) increase in atmospheric CO2 will be recorded in sediments all over the world. As will the changes in ecosystems as a response to warming climate.
Darkwing by Kenneth Oppel features a terror bird. It's a nice read. It's set 600 billion years ago with a lot of prehistoric animals featured.
Imagine being a cat with big teeth chilling and then a dinosaur comes running up on you and jumps you
Very enjoyable video about post-KT extinction dinosaurs.
Hey eons! I love your videos and am really happy you are making content about the history of the earth. I would love to see a video on how transitional species might be good as an explanatory idea, but don't really exist in the real world. Keep up the great work!
Blake's just so cool to listen to
I know it's a bit vain to admit, but I actually feel quite chuffed with myself that I spotted the time period mistake. Not in a smug way, at the presenter's expense. He's extremely wise and talented and eveyone makes mistakes sometimes. It's allowed.
But I felt chuffed because it made me feel that I am learning from these videos, rather than just letting random images and sounds wash over me and never really taking anything in.
So though the mistake appeared in this Eons clip, it's testimony to the quality of the whole rest of the Eons series that I had learned enough from them all to be able to spot it this time.
It's like student catching their teacher out. A mixture of pride in oneself and huge gratitude to them for getting you to that point.
Education is so sexy and empowering!
