Paleontologists have spent the better part of two decades debating whether Coelophysis ate its own kind. It turns out, the evidence that scientists have had to study in order to answer that question includes some of the strangest and grossest fossils that any expert would ever get to see.

How does one detect fossilized vomit?
"Here's an interesting rock."
"Dude, I made that same pattern at a party once."
Huh. Looks just like a Jackson Pollock.
@@ToddWrightthedrummer Nah that's semenlite.
Cariss preditory birds like Owls consume their prey whole then regurgitate a pellet of fur and bones. I would imagine these pellets fossilize quite well.
In the video it seems like the dinosaurs had thrown up in their mouths when they died, so the vomit would have fossilized when the animal was buried, vomit and all.
Lololololol
Imagine chilling with your bro, looking for some food, and he starts looking at you like a snack
That's just me when we're out of Cheetos.
Majungasaurus: I'm going to do what's called a pro hunter move
It's not just big brain time, it's big appetite time!
I love all of you
Then he just sucks the fart from your cheeks without asking smh 🤦♂️
"That meant that it probably hadn't exploded, which is nice!" -hank out of context 6:20
Incidentally, that is Kaplötke whenever he's in his lab.
So what you're telling me is that Simba ate all of the babies after he became King of Pride Rock?
Yep
Yes. And Nala was his sister

Which is why real lions exile male children when they come of age.
Cirrrrrcle......circle of life!
Right in the childhood!
The Triassic is definitely the most underrated geological time period
Tanystropheus, that long-necked piscivore, lived back then (oddly enough, Tany got into an episode of Spongebob Squarepants, "Lost and Found").
@Paulo Mendes sea not see.
I disagree, I do think it deserves credit as being the first in the Dinosaur trilogy (although they had a lot of unnecessary extra's that would be written out in the Jurassic) so they were working with some new ideas for sure. And without it we wouldn't have got part 2, the Jurassic, a tour de force of reptile action, so many cool characters and probably your best straight forward reptile on reptile action ever made to date. And without that we would never get the great conclusion either, the Cretaceous, where the directors really knew what they were doing with big names like the T-Rex and Triceratops et al, and the twist at the end with the meteor. Perfect. But the Triassic needed a relatable protagonist, a much much better villain than the Prestosuchidae, I mean come on, and a more dramatic ending too.
@@paulrussell1207 I disagree. It already had the Prosauropoda, as Plateosaurus, which were still young and not as experienced, but nonetheless versatile actors promising more.
But even greater was the underdog story of Eoraptor and his breath-taking rivalry with Herrerasaurus, and the shining grace of Staurikosaurus in the background.
And how could we forget the melancholy and gravitas given by the late great Cynodontia as they walk towards the biggest extinction period of the young Earth - a swan song of phenomenal proportions!
Granting the Rant nah, that’s the Cambrian
Started watching you guys a couple weeks ago, one of the best choices I've made in a while.
Agree.
I would binge watch damn near every episode if i were you !!! i know some days i rewatch some good ones bc they blow your mind! And make you think deep
Welcome! You're in luck.They have so many videos to catch up with.
@@edcrichton9457 I've been binging for a while, though with school starting back up I may not have as much time lol
They are fantastic. Have you seen their other stuff? SciShow and its spin-offs?
You're inside the PBS rabbithole aren't you? me too.
Could you do a video on parrots? I'd love to learn more about there genetics and if they were related to any other vocal learning ancestors
Maybe dinosaurs were smart and vocal like parrots. Or maybe they sang songs like song birds
@@SoulDelSol or maybe they didn't
I remember going to the city as a child, watching some birds being fed. A car pulled out, and one of the birds was run over. It's fellow birds walked over and started eating the remains.
What type of birds were they?
@@globin3477 probably pigeons, but as an ex-chicken owner i can confirm that chickens are cannibalistic, and will also just eat anything that moves in general, be it frogs, worms, rats, etc
Waste not, want not. Free protein is free...
@@rebevileovata6352
Blood on a chicken guarantees the flock will kill and eat it. Grew up on a farm. More to do with the confinement and stress if crowding than inate cruelty
I once saw a juvenile ibis eat the corpse of another juvenile ibis, probably its sibling. It's just nature I guess.
Hope you do one on Titanoboa and the animals from Cerrejón.
A video on post-Mesozoic giant reptiles in general would be really cool.
Stop turning me on..
I know they've mentioned the titanoboa in the past, but I'm not sure if it was a whole episode or not. That may have been scishow...
They’ve mentioned the post dinosaur reptile mega fauna before, so I wouldn’t say it’s out of the question
🙃
Any Carnivores will eat it’s own species if starving enough,.
Right up to and including
Humans.
Humans are omnivores, though I understand your point.
Mick C and some people do it cuz they like it: Jeffery Dahmer
And maybe environment that foster starvation also foster fossilisation, thus explaining the fossile record. Maybe.
You died of canibalism. The oregon train
there are indeed people who naturally eat people
Yikes, I even remember seeing that in Walking With Dinosaurs, but this is more explicitly graphic than the one depicted in the episode.
Invader Zim He could’ve watched re-runs on tv or on RUclips.
@@tacosalesman7544 Those usually go down on RUclips due to Discovery is tough on copyright.
Anne-droid is this a bad thing? even if they are young wouldn’t we want kids getting into paleontology and science, even though it may be gruesome?
My childhood spotted
@Big Boofman What does this even mean? Walking With Dinosaurs was my childhood. Have no idea what you're on about.
I just want you guys to know that I absolutely love your videos! Thanks for posting dope content for a (hopefully) future paleontologist (:
Avie Moreno I hope you chase your dream
Chase your dream. It'll be challenging but you can do it.
Also gonna try to become a paleontologist. Hoping to get into university next summer.
The key to it is to never give up, you got this!!
@@donteatthejellyfish that's pretty close. Good luck to you too ✌🏽
Yes you can...... just do it!
The Eons creators/producers/writers are fantastic. I was on the edge of my seat - is it or is it not a cannibal? They keep you guessing...
Hank hosting an episode of PBS Eons about dinosaurs. Perfect way to end a night.
A decade before you were born Hank, I loved reading Ned Colbert books. "Men and Dinosaurs" (1968) is probably my favorite of the many.
Killing everyone to limit competition?
I guess thanos was popular back then too
Actually, I kind of doubt that's what goes through the "mind" of a lizard eating smaller members of its tribe. AVOIDING eating a smaller member of one's own species would be indicative of some kind of discrimination taking place.
And who knows what goes through a lion who kills and maybe eats the cubs that were there before he came along? Maybe it's more that there's something about HIS cubs that causes him to refrain. We see how it impacts selection. We can see how such a gene would be passed on down the generations. But maybe those other cubs just have the stink of the old Pride Master on them. Or maybe he has to witness his own being born before there's any kind of bond.
Seriously, how do we get fossilized vomit!? Don't leave me hanging. Hank. Hank! Hank!....
Turns out that reading entrails can tell you more reliably about the past than the future :P
lol
I like that. A backwards kind of geomancy or osteomancy.
Anyone else remember this bad boy from Walking With Dinosaurs?
“I don’t know how, but you used the wrong formula and somehow got the right answer!”
-Edwin Colbert’s math professor, probably
Me doing anything calc and above. Feel like idk what I’m doing but it ends up being right
So that's your game PBS Eons, call them cannibals now that they can't defend themselves.
There is also proof of cannibalism in the Majungasaurus species
Yes, we talk about Majungasaurus in this episode! (BdeP)
I was going to say this too.
Majungasaurus is my favorite dinosaur.
@@eons Sorry, I didn't watch the whole video before commenting (obviously :-) ) what does BdeP mean?
@@yourstruly4817 Blake de Pastino's initials. That's the other male host's name on this channel. He was letting you know which of them was using the channel account to reply.
@@XoddamCXVII Thanks!
I just want to say I love this channel. There's so much incredible content that can help me learn about things in a fun and easy way for completely free. Thank you so much for making it and helping me understand how truly bizarre and wonderfully massive our planet and its history is.
Walking with Dinosaurs: New Blood (Episode 1)
‘Member?
I member.
Yea thats where i know this dino from XD
I saw the video title and immediately knew what they were talking about because of WWD.
@soldier_noscope Same

Hi PBS eons, Could you do a video on the progress of gravity and the atmosphere of the earth? Aprieciate your videos they are so great.
"Regurgitalites" Definitely my favorite word of the week, guess there is something to be said for prehistoric vomit after all.
We all just gonna forget the fact that chicken can also be cannibalistic or?
All carnivorous and omnivorous birds can become cannibals.
Chickens are brutal creatures, they remember when they used to be dinosaurs
@@celexia4 before they were bred for food chickens were bred for cockfighting.
I would like a video on how the Cave Bear’s lifestyle helped lead to its extinction.
Calling them fossils: ❌
Calling them earthghosts: ✅
Are you trance?
Yep I got hypnotized into being a girl
Fossil phantom. Rock wraith. Sediment spirit. Lich-lite. Dirt demon. Soil specter. Mineral manes.
@@vituperation Stony Boneys
I'm partial to biolith :P
Ive been binge watching you guys for about a week now
the moment I start watching a happy sounding song a notification about this appears......UHHHHHHHHHHHH?
Just let it happen
@@thereviewnetworks8244 Okay I'm a bit confused about what you mean...
@@Blue_Fire-Chibi Let It Happen
I love Paleontology!!
I love this Dino! I’m from New Mexico and I’ve seen these fossils in the museum of natural history!! I think this is our state dinosaur! I’m so happy that you covered something that focuses on the cool stuff New Mexico has, because most news covers the bad stuff. This is such a cool state!!
Anna C. Evanitz There are state dinosaurs?? Time to get googling 🤳🏼
Kelly Wolstenholme Yeah!! Missouri’s is Hypsibema! But our state fossil is a crinoid
If thousands of them were dead in the same area, it stands to reason that scavenging their own species for sustenance would have been as likely as cannibalism in that area.
I love this channel lol I’ve been watching it for years. I loved Dinosaurs and all the prehistoric periods since I was a kid, so having this channel to watch for fun (and knowledge!) sometimes is great.
I would like Eons to be shown during show intermissions on E or CBS.
Not only were they cannibals they also would borrow stuff and return it broken moths later.
And that's why the caterpillar population became extinct. I think.
Very intriguing stuff! As a plus, the track in this video is absolutely beautiful. Made me really contemplate life and existence as a whole
This music makes me feel like I'm lounging on a tropical island at sunset. I'm so here for it!
That moment when I get informed by my yt about new pbs eons video when I’m that tired I have a headache and yet I still decide to watch it! 😅❤️❤️❤️❤️
I would absolutely LOVE to see a video on speculative paleoart and how it assists in the progression of how we see dinosaurs and other ancient animals
A new eons video. Exactly what I need for my first day of school! ^^
Keep these videos up! Love the information!
Bone-ridden poop just makes me ask: Dinosaur hemorrhoids?
Man I love this channel, so interesting! Also Hank is the best host!
Majungasaurus was also a cannibal, but only when they were defending a carcass/young, they would just use them as extra food
As always a great production. I’d like to see one on the the disassembly of the junk taxon Insectivora.
Yes and no. The coelophysis discovered were shown to potentially be merely on top of each other, but cannibalism may have occurred.
Adymn Sani possibly due to lack of other food options, potentia scavenging and even imfanticide. Modern animals do that for the same purposes so why didn’t Dinosaurs?
They literally say all this in the video. Did you watch it or just respond to the headline?
skraddypoo yes to both
I've seen both the partial eatten remains of a chicken and goldfish both in an enclosure with their respective kind.
I saw 4 macaws and 1 cockatoo eat each other. The food had been tainted and 1 died and the rest ate him. They kept dying and the others would eat them and they all died
@@albenmurcia4716 seems impossible to me,considering macaws eat nuts and fruit
Nothing beats a classic dinosaur episode on Eons!
"Regurgitalites" a word that both surprises and delights me.
The phrasing of this is incredible and I need to remember this forever
Thanks! Well, it's taken me a few days, but I made it through all 98 episodes of Eons... and I want more!!! I can't wait for the next installment(s) to come out! Thank you so much for your great work - so far! 𝓡𝓲𝓴𝓴𝓲 𝓣𝓲𝓴𝓴𝓲.
I love Hank's voice 😊
I read the title and still thought it would be ok to eat while watching. Clearly I don't learn from my mistakes when Eons or SciShow pop up. 😝
Coelophysis fossils found in poop? One might say it was a Coelo-Feces Fossil...?
Just saying that when Coelophysis was named the intended pronunciation was seh-loh-fuh-sis, like in the word "physicist".
🦗
Very good sir. LOLOLOLOL
Uri Wolkowski k
FREAKING GENIUS
I love your videos so much! One of my favorite youTube channel. Can you maybe do an episode on penguins like evolution wise and why they live where they live etc. why are there penguins in Africa ? Never seen anything like this made about penguins. Could be fun. Just a suggestion. Keep up the awesome work.
Dinosaur: “yeah bro I ate like 20 of my kind”
*Cinnamon Toast Crunch: “HOLD MY MILK”*
It should be: hold my milk
LR Admirer :)
Excellent as always
Coelophysis: "Friends for dinner! I'm gonna have friends for dinner..."
Eons on a Wednesday! I’ll take it! Most of time a new episode is posted on Tuesday.
Man you are super articulate. The fossil reading thing is like forensic criminal investigating. You have to keep looking at the evidence
Interesting presentation. Thank you.👍
I just love the ukelele chill music that accompanies this cannibalism-themed video
WOULD YOU MAKE A VIDEO ABOUT TERRESTRIAL GONDWANIAN CROCODILOMORPHS????
"Yes!" now, science later.
That's how I approach this question.
Excellent video as always. While on the topic of dinosaurs though: With the recent description of Heracles inexpectatu, I would be curious to see something about parrot evolution (and not gonna lie, my interest in non-avian dinosaurs eventually lead me to getting parrots of mine). Though if that's too spase in terms of available data, a video on psittacopasserae
and their vocal abilities would be great. In terms of what we know about the evolution of parrots' and Passeriformes' ability to mimic speech and do complex vocalizations.
Love this channel
just realized Im looking at their last meals... trippy
What about Medusa evolution? They seem really far from other groups
Exploding Dinosaurs. Nothing like PBS Eons. Keep up the good work!!😁
Great show!
Well, yeah, that was a closer examination of poop than I anticipated seeing. Ever.
That's why I never ask for a colo light
Well done young man & very interesting !
You ever wonder if some dinosaurs were some what intelligent and buried their dead sometimes.
Honestly it crosses my mind a lot.
I can tell you from personal experience that chickens are cannibalistic. This may shed some light on the behavior of their ancestors (which I believe are the T-Rex).
It’s not just ceolophysis you have to think about here, you also have to think if other members of its family also did the same thing.
cracks me up everytime Eons casually mentions how T-Rex's are now pidgeons
I really wish I could know more about the speakers... They seem so knowledgable!!!
Bring on the blood!!! How about a video of all the strange and different ways fossilized animals showed they died!
What do we know, how do we know it, and how graphic can it get?!?!?!
Very little in nature dies of old age and I'm sure this is going to get crazy. Be a great Halloween special!
Will you do a video about the evolution of birds like penguins or hummingbirds? I think it would be very interesting :-) btw this video was also very interesting
Guys love your videos. It would be a nice idea to make a video about ice age megafauna of madagascar such the giant lemurs and the elephant bird.
Past midnight before an early rise: Oh PBS Eons just posted. I can live without sleep.
Keep making vids like this And my great great grandchildren will still be dino fans like me a 13 yr old dino expert
I live a few hours away from Ghost Ranch
Lilly Dragon ok
A few hours walk, or by car, or by train...maybe plane?
You guys do a great job
Excellent! Thanks.
why theres no quadrupedal bird species?
Because there hasn't yet been any selective or biological pressures to produce quadrapedal birds.
@@HenrythePaleoGuy There's also the constraint that most animals (arthropods and their relatives being fun exceptions) can't really have more than four limbs. It would be interesting to be proven wrong, though.
@ryan dika
There is one. It's clumsy, and it's bipedal as an adult, but it does use its wings as arms/legs when it's a baby
www.insidescience.org/news/baby-birds-use-wing-claws-climb-through-amazon
Because birds are avian theropod dinosaurs, and theropod dinosaurs are almost all bipedal. Plus, the theropods birds are most closely related to were bipedal, the paravian dinosaurs like microraptor and sinosauropteryx.
All of these videos are the most satisfying clickbait ever
huh this video isn't a clickbait tho
keep them coming!
Just wondering could you guys do an episode about the once massive Amblyrhiza inundata that lived on St Martin and Anguilla.
8 views wow. Yay new vid for my day off!!
So what I learned is to discard the bones. Got it.
CleanerBen - 😎
@@lestatangel hehehehe 💀
Cursed comments
Okay but the lil birdies at 1:58 might be the cutest things EVER
Yay Coelophysis! It’s our state fossil here in New Mexico
That's really interesting! I didn't know that.
They never thought those two were pregnant 🙄🙄
Great point!! That's like when children think babies grow in their mother's tummy or belly. It's womb not stomach
Also more likely to have skeletons from long term pregnancies then a brief meal
@@SoulDelSol I mean they were in the 15th century, those people were stupid, they're the reason why I have to study more 😤😤
I raised chickens years ago. I had a small group of about 10 Barred Rocks that roamed free on 1 acre. These were basically pets, and they were fed a high quality diet. One day a hen hurt her leg. I can't remember how, but it was a minor muscle injury. Once the other chickens saw this, they swarmed on her to eat her alive. I was able to grab her and put her in my garage for about an hour, until her leg seemed fine. When I put her back outside with the others, they 100% ignored her. I know these are not wild birds, and chickens are amongst the most domesticated of all animals, but that cannibalism gene probably existed in the original jungle fowl.
I yearn for the day we have enough fossils and/or advanced technology to get an idea of what dinosaurs actually looked, acted, and sounded like. I'm not going to hold my breath we'll ever actually get there, but I can dream.
Actually I was Fourth my appoligies
BIG CHUNGUS!!!
