Carnotaurus: The Ultimate Predator of the Late Cretaceous
Vložit
- čas přidán 12. 06. 2024
- Carnotaurus is a genus of theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 71 and 69 million years ago.
Carnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern landmasses of Gondwana during the late Cretaceous.

This channel really gets in depth of real evidence of what Dinosaurs looked like 👍🏽 Great job, I just subscribed 🔥
At 6:05 this is what I look like when people piss me off😂😂
Honestly, the Carnotaurus has been one of my favorite dinos since I was a kid, thanks largely to Disney's 2000 movie Dinosaur. Always cool to see such a well put-together viddeo about them!
Thank you very much for watching and appreciation!
This was really interesting! Thank you
Thank you very much! I am planning to make more such vids. The next is going to be about the Triassic period.
Love carnotaurus!! Like your video said, I also believe they must of had much larger horns than the bony core left behind.
Thanks for watching! Yeah, the thumbnail shows exactly what it was said in the video. I am even more impressed by the structure of those horns.
One of my fave dinos
Yeah, real monster with strong legs and nice horns
I have always been fascinated by dinosaurs and ancient animals
Then this channel is a good place for you. Enjoy more this month with the coming topics such as Spinosaurus, Triceratops and dinosaurs of Jurassic period.
I've always liked the carnotarus, but those "longhorn" reconstructions just look ridiculous. Is there any actual evidence their horns were that big?
They had a keratin sheath horn over the bone likely. Theoretically could be any shape
Maybe no evidence but it sure as shit looks awesome !
Many animals today have a similar pattern. For example, if you look at a ram skull, the bone part of the horn is relatively small, but supports a much larger keratin horn.
The point here is that only the bone part of the Carnotaurus horn was fossilised. The size of the actual horn is only speculation. There is no evidence it would be that large, but there is also zero reason to believe it would be limited to the size of the bone, as that is not how horns work.
Not like Jurassic Park is even close either
@@yan7314 WRONG.
The first species to develop a phobia of getting the check at lunch.
So many animals we never got to eat 😢
What I have recently noticed that many people wish to eat extraordinary animals they see on CZcams videos LOL
It's horns were obviously used to absorb lightning and power it's night vision
Giganotosaurus lived approximately 25 million years before carnotaurus so it's unlikely that they ever met.
Fantastic, thanks so much for putting this out there for us to enjoy and learn from
You are more than welcome🙏🏼 thanks for watching!
the horns probably shielded the eyes from the sun above and reflected light into the eyes at night. it was a sweet predator for sure
If it lived nowadays, we would definitely pet it.
@@CreatorOnline2.0 your right, it would probably end up with a saddle on it :)
"The Ultimate Predator of the Late Cretaceous"
T. rex is somewhere in a corner is spitting out his coffee right now to that title.
Double expresso is more for it
The horns look like they were used to sideswipe their prey and bleed them out.
Ramming each other doesn’t make sense at all!
so cool that napoleon discovered the carno
A more developed sense of smell, compared to its eyesight, like a vulture, points to scavenging being carnataurus' primary MO. Especially when considering the presence of larger and diverse theropod species. Horns then, could also be an adaptation for fending off competition from carcasses. Perhaps even giving Carnataurus an edge in harassing larger theropods like gigantogosaurus.
Not at all. Hunters need a good sense of smell, especially in the topographical terrain this animal lived in. All carnivores are both scavengers and hunters - they are opportunists, even the turkey vulture is so.
@@user-ek4iy5wp4hI stand by my analysis. The turkey vulture is an obligate scavenger. Like the carnotaurus, it has a highly refined olfactory bulb. In birds of prey, most generalist hunters like eagles and other acciptrifornes are less olfactory reliant and more visually reliant to find food.
A study of modern raptors, ( the associated article linked below) found that the olfactory sense in an obligate scavenger (the turkey vulture) did indeed play a much greater role in it's foraging compared to visual cues than it did for a generalist hunter (the southern caracara):
"In this study, we found clear evidence that both Turkey vultures and Southern caracaras can smell, and thus find, the hidden food. However, while it appeared that the sense of smell may be a primary foraging sense in vultures, at least in our experimental setup, this was not the case for the Southern caracaras."
Considering the obvious connection between dinosaurs and birds, and more specifically ancient theropods and modern raptors, it would seem abundantly evident that any carnivorus dinosaur showing evidence of a much more refined olfactory sense, compared to its sense of sight, would most likely have feeding habits heavily predicated on the use of that superior olfactory accuity: meaning it uses its sense of smell to find dead things to eat that it can not otherwise see, in much the same way modern turkey vultures do today in the forested areas they inhabit.
Considering these facts, it would seem obvious, given the make-up of it's brain, that carnotaurus was in fact an obligate scavenger, and not a generalist hunter at all.

Ever since I was a young kid, the Carnotaurus has been my favorite species of dinosaurs. I only wish there were more skeletons and fossils found of this species.
Although the single skeleton that was found and studied, who knows maybe it may have been possible for the Carnotaurus to have grown a little longer and heavier. I find it odd only one specimen has been unearthed from the deserts of Patagonia.
Who knows, maybe paleontologists will find more skeletons of it.
The specimen is an adult and it is likely that it is typical for all adults of the species.
I only know this Dino because of the Disney movie, dinosaur
2:06 The artists impression of a dead (what I assume) mosasaur is hilarious. Little pterosaurs living inside of the mouth of the mosasaur!! The carnotaurus is meant to be about 8 metres long and the mosasaur is around 15 metres long, yet in the video the carnotaurus is only half the length of its head! Also according to Wikipedia an adult carnotaurus weighs about 2 tons and the mosasaur weighs 10 tons or 5 times more, yet in the video the mosasaurs head would be more than 5 times the weight of the carnotaurus.
That was a baby carnotaurus who was being accompanied by his brothers, mother and father in the video.
This guy just regurgitates Wikipedia
I wonder if they also shed skin periodically like snakes or lizards…
I remember loving carnos.... Until one showed up outside my house and ate all my dodos and parasaurs 😢
What is the length of the largest fossil horns? In other words, is the depiction of the individual with long horns accurate?
Its size was around 15 cm, not sure how big are those shown in the image. It is more a paleoartist’s imagination.
Hello My Name is Braulio Darias I’M Deaf The Watch That Video Have A Great Thanks
So sorry that I can not make subtitles on my own since it is very time-consuming. But there thanks CZcams has auto-subtitles. Thank you very much for watching my video! 🙏🏼
Seems like their short lifespan contributed to the extinction
T.rex has read the title... it would like a word with this channel.
Giga
Tiny arms could be wings
So in the end , the horns does used as weapon?
Abelisaurs make me happy because it means descendants of my favorite dinosaur, Ceratosaurus, lived on.
What about Spinosaurus? My next video will be about it
Carnotarus was a great dinosaur but ultimate predator ? No far from
Makes sense carno has no signs of feathers, not every dinosaur has gonna have had feathers, you'd imagine, early, to late cretaceous species, mainly for raptors to have feathers. They had use for it. Same I would argue, Tyrannosaurus would have no feathers because it would have no use for them.
What's your argument of "not needing them" for the trex?
What's your argument for it needing them? @@LotharSB
@@luigiconder6113 Bruh i'm asking a question because i want to hear his argument? Not because i know better.
How do you know all stuff about the carn’s life cycle?
I did research, also if you have something to add or correct, go for it. I love learning new thing
I have no doubt you did your research. My problem stems from the initial premise. I can guarantee what you speculate on is considered fact by others. Fossils tell us a lot but they only tell so much.
Could you imagine the large sheets of dead skin when it did shed its skin?
I think the horns were for getting unwelcomed dinner guests thinking twice having a meal with one of those guys.
I have on good authority that the horns are a specific adaption for backscratching since the arms certainly weren't capable.
You meant to say you have IT on good authority - however, your authority has been taking LSD, and is not reliable.
Huh? I missed a JJ Mortimer release?
Seems like yes…
@@CreatorOnline2.0 ah. Carnotaurus was from 2 years ago. Didn't see that one before
you thought T rex had flimsy arms ^.^
Carnotarus naturo run origin
1:39 Its skin looks like the layout of a fortnite map🙋
Its cousins, Carnivalosaures, were a lot more fun.
so uncanny, with the little little arms, like a sausage with legs.
What’s this from? 0:01
If you are asking about the footage, then it is Julian Johnson Mortimer
@@CreatorOnline2.0 thx g
What is the comically vast Pliosaur all about ?
So those horns make no sense
Can you spot the huge green dinosaur at 0.11?
Given Carnotaurus' arm size, this gives a possibility that a Carnivore without arms and a huge neck may have existed
Specify: strong neck with lots of muscles
No.
Yes.
A lot of contradictions in the text. At one point you say it was the dominant predator, another that it lived with Giganotosaurus. At one point that it lived until 69 mya, at another 66 mya. Theres more. Plus, much of the artwork is ridiculously innaccurate.
They squat
What if a Maip macrothorax enter the Battlefield the Carno will die and cry 😂😂😂
So it ran like Naruto
I just skipped through your stuff and subscribed. I love your videos and I also think the new narrators are doing a fantastic job but I kind of feel you should switch back to your own voice to make them _really_ stand out. The accent especially lended your older videos a lot of character.
I also think that my own voice is fine, but I have limited time since I work full-time as a journalist and at the same time I learn coding. So, it is extremely hard to allocate time for all of these, but CZcams is my passion and I enjoy making videos.
Oh sure...I thought it might be that after I posted! That's indeed a _very_ valid reason. I'm probably a little biased because I have seen a bunch of youtubers resort to narrators out of shyness (and saying so) before.@@CreatorOnline2.0
imgine if evolution would have let them a few millions longer… we would have had the first dinosaurs without arms, like excetinct elephant birds
Maybe they existed and we haven’t found fossils yet. The fossils found of dinosaurs cover less than 2% of all dinosaurs that existed
Carnotaurus: My advice: Do a lot of leg work at the gym, arms are overrated.
Pretty much 💀 too bad man’s ain’t the strongest, smartest, or bulky
In general terms it was the same unknowable force that wiped them out which helped form our planet.
You're not a biologist are you!
Wrong!!!
"Ultimate predator of the late Cretaceous" looks like the ultimate Cretaceous clown with them giant horns. 😂
For a moment think about its leg muscles, intelligence and sense of smell. Definitely, not a clown.
@@CreatorOnline2.0 3 Tons, as fast and agile as a modern African Lion. Definitely a predator worthy of respect.
@@HeWhoMurksWithOneLeap That thing runnin right at you, imagine how terrifying. Even from way across a field with a valley. It would still catch you if you turned to run. You would hear it;s thumping feet getting closer and it;s steady breathing knowing it was focused on you. Hope someday someone makes a true horror dinosaur movie with brutal gore.
@@StevieSeagal If Hollywood does a scene with this dino I'm sure they'll butcher it. Lots of fake blood and a guy doing a wheelie on a motocross while a buxom blonde clings to his backside and the dino is just inches behind, at 60 mph.

Completely not! The Voiceover artist is from the USA and video editing is done by me.
