- Meet AAAS member Daniel Field and Yale Peabody Museum’s mascot Torosaurus, a frilled dinosaur that recently went through an identity crisis when it was argued it was actually just an adult Triceratops.

Congratulations your triceratops has evolved into torosaurs
Well this definitely settles the long question I’ve had about these two species. Triceratops and Torosaurus are two different ceratopsians.
Jack Horner: Nuh uh
Thank you, now I have a video to send to fellow paleontologists when they claim this goofy theory.
我很好奇為何以前的人會認為牛角龍是老了以後的三角龍 ? I am curious that why the people thought that a Torosaurus is an old Triceratops before ?
ua-cam.com/video/kQa11RMCeSI/v-deo.html this is a Ted talk by Jack horner, he cut open the bones and found out that the bone structure of juveniles triceratops are spongy but then he found out that the "adult" triceratops was also spongy. And he also cut open the bones of torosaurus and found out that it has a mature bone structure and there wasn't any juveniles torosaurus fossils found
And where are the Babys?
Torosaurus could have been a MALE triceratops, showing sexual dimorphism.
Or two different species, as you said.
But that the difference is because of age maturation is very unlikely, for the reasons you mentioned.
Either same species of different sex, or different species, but not different age.
Why would a male trike have literal HOLES in its frill while the female dosent? Hmmmm
Ceratopsian dont need holed to make their frills pretty
@@Koremel1 "Pretty" is a subjective human concept. Display for sexual purposes generally show healthy features. In the case of chasmosaurines, a holed frill could make the skull lighter and thus easier to wield in duels. As for the your questions in general, the answer is NO ONE KNOWS, that is why we study fossil reccords and try to theorize the most probable ways they looked and behaved. When you build a TIME MACHINE and go visit them in the past so you can see for real how they looked and behaved, then you can come back and explain to us all about them. Until then, feel free to have your own opinion like the rest, which is just that, an opinion, and all the truth you are going to get for the momment.
No, there's no evidence of such extreme sexual dimorphism in any large Ceratopsians...
Well the issue with that theory is within some specimens of Triceratops Horridus (Including the one displayed at the science museum of Minnesota) have small puncture wounds and holes that were inflicted by the same species in combat. No specimen of Torosaurus has ever been found like this. Having the idea of Torosaurus being a male variation of Triceratops by sexual dimorphism is lower than predicted to be and is more towards the evidence of both being entirely different species.
Nevermind that the Triceratops is bigger (6.5 tons vs 10 tons maximum sizes)
Maybe it's just a gender thing?
Even if this was the case, wouldn’t Torosaurus be discredited as invalid?
For consideration: have male and female fossils been found of both species?
If not, another hypotheses would be that these ARE the same species but rather than being at different levels of maturity, they are separate genders. What if, for the sake of defending their young, the females grew larger and had shorter/tougher frills, while the males had larger, possibly colorful frills in order to attract mates?
A fantastic summary very approachable by the way man. Used this a few times while giving field trip talks to older crowds. Really nice to have considering some other videos on this subject are Jack Horner echo chambers.
Jack Horner has really fallen from grace. It seems these days he’s saying controversial things just to get attention.
You know I read up on the paleontology world every now and then, and last time I decided to read up, I heard about Triceratops and Torosaurus supposedly being the same species, now I see this.
I guess that's just a testament to the fact that we'll never know the full truth behind these animals, been dead for ages to the point where only reconstructions exist. And skeletons at most are around only 98% complete. But it's always fun to learn more about them, they're magnificent creatures.
It's a little sad in a way
TOROSAURUS
Thank you for uploading this. I don't know what people postulating this theory were thinking. The skulls look so radically different even if we focus only on the frills. Hard to imagine how (or why) a frill would change so much over an animal's life. The two skulls shown in this video look to be of very similar size except for the frills. So, unless there was marked sexual dimorphism which would be the only other explanation, these specimens are definitely two separate genera.
Sexual dimorphism was what sprang to my mind specifically with torosaurus being the male. I believe its been found that the frill and horns go through the biggest changes during peak maturity which would suggest that they play a role in reproduction so males having a larger frill as a display would make sense. Also the holes in the frill could have been used in dominance combat where instead of males goring each other they could "lock up" in attempt to out leverage an opponent much like deer do today with antlers.
@@BubbleZBlofish it's a outdates theory
@@BubbleZBlofish triceratops are largest of its kind we have new evidemce
@@BubbleZBlofish and triceratops had healing Mark on its frill why females will fight
@@BubbleZBlofish The "holes" would've been covered in skin. If they were marks to "lock up" they would've been pierced constantly and infected.
Why ain't I surprised....
Greetings bibia.
Ps I had to look this up... I saw an video from Denver Museum of Nature & Science in which a scientist thought torosaur (Tiny) was just an adult triceratops... And I was goblesmacked, I could imagine torosaur being male and triceratops being a female... But torosaur being a adult triceratops seems ridiculous!
I heard Torosaurus was a bit more common than triceratops. I don't know if that's actually true.
Wrong, Its Triceratops was more common
@@amn2760 oh ok
@@usmanya5110 Thats why there werent any juvenile Torosaurus has been discovered
@@amn2760 I wonder how they might behave apart from each other. My theory is that one of them is a social animal like previous ceratopsians and the other one is solitary. I think toro is the most likely one to be social due to its weaker frill. Triceratops can also be social but once they reach adulthood they become solitary. If im remember... there was evidence of juvenile trikes together from the badlands. But then again that's just a theory I can't be sure about that.
Triceratops were more common and inhabited most of the northen territories, meanwhile Torosaurus inhabited the southwest and was lower in numbers
Or, as I like to put it, since 2016, the number of chasmosaurines with names not ending in -ceratops has doubled from 2 to 4, not tripled from 1 to 3.
Torosaurus, Chasmosaurus, Einiosaurus and… Idk what the other one is
@@hunter133official Einiosaurus is a centrosaurine, specifically a pachyrhinosaurin. The other 2 are Spiclypeus and Terminocavus.
@@VWftw82 I have never heard of those 2 no wonder why
Also, yes I made my mistake
Yes finally someone debunks this dumass theory. And to me saying that triceratops and torosaurus are the same species is like saying that elks and deer are the same species
Where are the Babys?
Or is this a bias, what if we discovered torosaurus before triceratops, the would we believe that triceratops was a juvenile?
Now we need to apply this to pachycepholosaurs and tyrannosaurs.
It’s possible all of them could have been separate species instead of different growth stages
It is for T-Rex, Nanotyrannus in the end is a juvenile Tyrannosaurus
Torosaurus is full grown Triceratops. Get over it and move on.
cope and deal with the facts
Wrong Torosaurus and triceratops belongs to the same family but different genus
So youre saying that the smaller genus is the mature form of the larger one? 😂
