A few ways to explain away the size of the centra is A) That it belonged to a Sauropod B) That the animal it belonged to had fewer tail vertebrae than other carcharodontosaurs, making each one longer on average to increase rigidity and balance C) That the fragmentary nature of it indicates it could be misidentified as a middle caudal centra and instead be one closer to the hips and therefore longer. 16.8 meters does sound pretty outrageous and unlikely. Though isolated elements have broadened our understanding of what was possible in species size before, such as the big old Temnodontosaur bones that put the 10 meter size into question. Sometimes though, there are just too many unknowns, this case seems to be one of those.

After seeing the hype around other Carcharodontosaurids that were "bigger than T-Rex", I'm afraid that with enough research it's size will be estimated to be not bigger than T-Rex. Still, Giganotosaurus is pretty much as big as T-Rex, but less thick. So may it be with any other Carcharodontosaur, I think. Maybe the speed of neural impulse(15 m/s) limits the size of the efective predator to 12 meters and 8-10 tons.

Plot twist: it’s another fragmentary massive Megalosauridae I mean we atleast know of 3 giant specimens and 2 likely genus’s bigger than even the biggest Saurophaganax’s and Torvosaurus’s: Megalosaurus Ingens, Giant French Megalosaurid (nicknamed most commonly Francovenator), Unnamed Spanish Megalosaur. Granted these later 2 likely are the same as a new giant Megalosaurid, meanwhile Megalosaurus Ingens (Uruguay, Tanzania) though seen as being Torvosaurus has the issue that it’s in the wrong time and Torvosaurus never made it to Gondwana yet Megalosaurids ruled there (likely a new genus by logic.)
Probably a fragment of a Sauropod or something: [Exists] Jack Horners Existence: [Rubbing Hands together] MY CHILDREN, WE SHALL ATTACK ONCE MORE!! THEROPODIZE IT! [Insert Rex battling the claims of a 20 TON CARNIVORE]
Man i can't belive it, I SO HAPPY that my country probaly have the biggest theropod( still i belive something larger have lived here) but for sure i don't thing it is like 20 tons, if i could think i think its a carcharadontosaurid, or its the carcharadontosaurus sp or a Giganotosaurus
Absolutely impossible For real though these remains are garbage, which is why I included so many disclaimers saying that this is not whatsoever a reliable specimen and that we have no actual idea of its size. Don't trust these estimates
Though I agree that 20 tonnes is laughably exaggerated, there is still a possibility that a a predator rivaling T-Rex and Gigantosaurus in length (and maybe weight) isn't that big of a stretch. After all, this is the land of the titanosaurus
03:00 Maybe already discovered super gigantic Megaraptora from Anacleto Fm. I found some blogs about this specimen size 13.6m / 8.9t from the anterior dorsal vertebra (MCF-PVPH 418), And the largest Theropod footprint is 115cm from Bolivia 80 Ma. Both were probably the largest Theropods??? (maybe Megaraptora???). Can you recap this please (I'm not sure about that) Ref. in comments

The giganotosaurus from Dino Crisis 2 is becoming more and more real XD (although in this case it is not known which family it is from, since it is only 1 bone)
Arguably, charcharodontosaurs could ill-afford record-breaking restrictions on their agility. How would a crocodile-brained ambush predator lug 20 metric tons into a pell-mell? Scattering a herd of colossal quadrupeds with little more than a gang of disorganized rivals, sidling up beside the nearest straggler, peeling off a worthwhile strip of flesh, turning tail, and navigating the gauntlet of fugitives ALL BEFORE drawing either a kick or a tail lash from any direction would have required nimble footwork as much as it would decent peripheral vision.
Caudal vertebrae is 45% longer than Acrocanthosaurus, so extrapolate to say that the entire theropod is 45% longer than acrocanthosaurus. Then by square cubed law, a 45% increase in length yields a 200% increase in volume, and since density is basically the same for all animals, 200% increase in mass. Acrocathosaurus is thought to be around 6 tons, so a 200% increase would be roughly 18 tons. The obvious problem is assuming that this new theropod and acrocanthosaurs have the same dimensions. There is no reason to believe this given the fact that we only have a caudal vertebrae and we aren't even sure if we have a carcharodontosaurid. But it's not an idiotic estimate, its pretty reasonable given our lack of information currently.
While I believe 20 tons is too much, I can see some sort of weight corelation here. Maybe T-Rex is the limit for Theropods, where they get heavier rather than longer? Which is why it gets so much heavier rather than longer? I mean T-Rex is possibly 12 tons, which is ENORMOUS
Il existe plus theropode qui aurait une taille supérieure a 12 m donc le t.rex n’est pas une limite de plus tyrannosaurus rex ne vivait pas avec beaucoup de sauropode géant contrairement aux theropode qui vivait plus aux sud comme ( en Afrique, Amérique du sud et en Asie du sud) il me semble logique que les plus grands et gros theropode apparaissent dans ces régions. Et pas dans le nord
I would name it Megacuadalsaurus rex, translated to Big Tail Lizard King. Love you videos. Im currently try to use other therapods like carcharodontosaurids and megaraptora and 2 other genera tyrannosaurus for lols, and saurophaganax (my favourite along side Ceratosuchops and deinocherius) cuase of it possibly an ancestor to Carcharodontosaurs
Probably the only reason I watch these channels is because I know you are the kind of nerd that will directly take a look at the study and not just relay the click bait news from whatever garbage and clickbaity paleonews we usually get elsewhere. Thanks you for doing that.
@@BrendonjacobDedaceI honestly never heard of that. I heard claims about Velociraptor being considered intelligent but back then the assumption is that most big predators are doo doo brain
Any 20 ton therapod is going to be next to immobile unfortunately. The T Rex is already shown to have been struggling at around 10 tons, IMAGINE DOUBLE THAT.
I'm from Brazil and I live in the Northeast. It would be a great surprise that one of the largest known theropods lived here, unfortunately my country does not invest properly in paleontology field research, it is a shame.
1.Basically I am not convinced by the estimate that based on fragmentary material. Although if said creature was really a Carcharodontosaurid,I would like to name the species after Incan deities. It would more thrilling if the fragmentary material came from a Megaraptora. Edit: 2. As some replies here wanted to name the dinosaur after Godzilla,I am curious about Vividen’s thoughts on Kenneth Carpenter’s thought experiment in 1998,in which he tried to classify Godzilla as some Abelisaur or Ceratosaur “Had Godzilla was a species of Theropod dinosaur.”
Many of the dinosaurs that we found were killed in events such flash floods or died in tar pits.... Meaning that many or most of the dinosaurs we found died prematurely ..... Knowing that many of them kept growing for their whole life, we could assume that certain specimens, that had a longer life than those who died prematurely, would eventually reach bigger size and may never be discovered....
as soon as I saw the length of the bone compared to acro I audibly went "0 percent chance this is a carcharodontosaurid". I refuse to get my hopes up about this shit, COMPLETELY personal stance on this is that I do not at all think this will end up being a theropod, but it would be cool if it was
it should be called Lustianisaurus after the fact that Portuguese is called lingua Lusitania in Latin, but also because of the giant ship called the Lusitania that is also the lesser known forgotten giant ship tragedy
I don't find it super surprising if there were T. rex and beyond sized theropods throughout history, what with the size of some of their prey. Anyways I'd name it Jeff
If it is indeed a carcharodontosaurid, I would guess it is in the same size range as Mapusaurus and Giganotosaurus, so probably a 40 foot animal. Massive, but not astronomically huge.
If this does somehow end up being accurite, I can't wait for the universe the adibly bend and creak just to spawn a 21 ton trex skeleton as it seems to do every time anything bigger is found

@@laseriedeladilophosaure9246Je suis d'accord avec vous, le Giganotosaurus est plus gros que le T-rex, car lorsque le Giganotosaurus a été découvert, il a immédiatement surpassé plusieurs spécimens de Tyrannosaurus rex, si je ne me trompe pas, le T-rex moyen mesure 11,2-12 mètres et 8- 9 tonnes et les plus grandes mesurent 12,1 à 12,6 mètres de long et les condoléances 11,5 à 12,4 tonnes. Le premier spécimen de Giganotosaurus mesure 12,8 mètres, il a surpassé tous les Tyrannosaures, c'est-à-dire que le premier spécimen de Giganotosaurus n'est pas encore le plus grand, le deuxième spécimen de Giganotosaurus est plus grand que le premier, avec 13,2 ou 13,6 mètres de long, et certains estiment le la seconde mesurait 14 mètres de long. En plus du Spinosaurus et du Giganotosaurus, y en a-t-il d'autres qui peuvent être plus gros que le T-rex ? Comme Mapussaurus, Carcharadontosaurus, Tirannotitan, Acrocantosaurus et autres ?

Someone suggests that 20 ton theropod could exist and everybody loses their minds.

Btw i calculated the height and is 7.4m tall 💀
Não duvido ser um megaraptoriano quadrúpede gigante. Megaraptores tem patas dianteiras muito longas, e poderiam ser quadrúpedes facultativos.
Então um Megaraptoriano totalmente quadrúpede não é tão estranho, e isso explicaria o peso deste espécime.

I honestly think the size of whatever that thing is, is more likely to be 9-10 tons but I might be just stupid
If it ends up being the winner as biggest theropod, then they should call it Connorsaurus Immortra after the character Connor MacLeod from the film Highlander (1986), due to the famous line:
*There Can Be Only One!*
I would name it
Brasilosaurus Impavidus
In reference to the "impávido colosso" part of the Brazilian anthem
Apenas Impavidus Colossus, já seria um bom nome.
Until more material is out, I won't believe it then. Im gonna hedge my bets on it being a long boi. That mass would be too detrimental.
16 meters long and twenty tons? Sounds like a Vastatosaurus Rex from Skull Island.
Ironically V.rex's canon weight is 8-10 tons despite being 40-50 feet (12-15 meters)

Hey I Watched Your Video If Real Life T Rex Was In Skull Island
Plot twist: it’s another fragmentary massive Megalosauridae I mean we atleast know of 3 giant specimens and 2 likely genus’s bigger than even the biggest Saurophaganax’s and Torvosaurus’s:
Megalosaurus Ingens, Giant French Megalosaurid (nicknamed most commonly Francovenator), Unnamed Spanish Megalosaur. Granted these later 2 likely are the same as a new giant Megalosaurid, meanwhile Megalosaurus Ingens (Uruguay, Tanzania) though seen as being Torvosaurus has the issue that it’s in the wrong time and Torvosaurus never made it to Gondwana yet Megalosaurids ruled there (likely a new genus by logic.)
Probably a fragment of a Sauropod or something: [Exists]

[Insert Rex battling the claims of a 20 TON CARNIVORE]
Meanwhile, there are other Carcharodontosauridae in Brazil
I only know about the new ichthyosaurs arguably the biggest marine reptile ever lived
A video on those is in the works!
Man i can't belive it, I SO HAPPY that my country probaly have the biggest theropod( still i belive something larger have lived here) but for sure i don't thing it is like 20 tons, if i could think i think its a carcharadontosaurid, or its the carcharadontosaurus sp or a Giganotosaurus
I strongly doubt it's 20 tonnes, but whatever it was it was definitely big! How big, we can't tell for sure since it's so fragmentary
I would use the word probably sparingly in this case.
I hope we find something like that kaimeren aquatic megaraptoran monarch.
Vividen try not to overhype the most fragmentary remains ever challenge (impossible):
Absolutely impossible
For real though these remains are garbage, which is why I included so many disclaimers saying that this is not whatsoever a reliable specimen and that we have no actual idea of its size. Don't trust these estimates
Though I agree that 20 tonnes is laughably exaggerated, there is still a possibility that a a predator rivaling T-Rex and Gigantosaurus in length (and maybe weight) isn't that big of a stretch. After all, this is the land of the titanosaurus
03:00 Maybe already discovered super gigantic Megaraptora from Anacleto Fm. I found some blogs about this specimen size 13.6m / 8.9t from the anterior dorsal vertebra (MCF-PVPH 418), And the largest Theropod footprint is 115cm from Bolivia 80 Ma.
Both were probably the largest Theropods??? (maybe Megaraptora???).
Can you recap this please (I'm not sure about that)

The giganotosaurus from Dino Crisis 2 is becoming more and more real XD (although in this case it is not known which family it is from, since it is only 1 bone)
Arguably, charcharodontosaurs could ill-afford record-breaking restrictions on their agility. How would a crocodile-brained ambush predator lug 20 metric tons into a pell-mell? Scattering a herd of colossal quadrupeds with little more than a gang of disorganized rivals, sidling up beside the nearest straggler, peeling off a worthwhile strip of flesh, turning tail, and navigating the gauntlet of fugitives ALL BEFORE drawing either a kick or a tail lash from any direction would have required nimble footwork as much as it would decent peripheral vision.
What kind of idiotic estimate is 20 tons? Wth?
Caudal vertebrae is 45% longer than Acrocanthosaurus, so extrapolate to say that the entire theropod is 45% longer than acrocanthosaurus. Then by square cubed law, a 45% increase in length yields a 200% increase in volume, and since density is basically the same for all animals, 200% increase in mass. Acrocathosaurus is thought to be around 6 tons, so a 200% increase would be roughly 18 tons.
The obvious problem is assuming that this new theropod and acrocanthosaurs have the same dimensions. There is no reason to believe this given the fact that we only have a caudal vertebrae and we aren't even sure if we have a carcharodontosaurid. But it's not an idiotic estimate, its pretty reasonable given our lack of information currently.

>20 tons
Yeah that seems pretty fucking extreme.
T rex=hater😂
If this does turn out true, the dino crisis 2 giga does have a irl counterpart
"Usurpator" would make the best genus name
While I believe 20 tons is too much, I can see some sort of weight corelation here. Maybe T-Rex is the limit for Theropods, where they get heavier rather than longer? Which is why it gets so much heavier rather than longer? I mean T-Rex is possibly 12 tons, which is ENORMOUS
Il existe plus theropode qui aurait une taille supérieure a 12 m donc le t.rex n’est pas une limite de plus tyrannosaurus rex ne vivait pas avec beaucoup de sauropode géant contrairement aux theropode qui vivait plus aux sud comme ( en Afrique, Amérique du sud et en Asie du sud) il me semble logique que les plus grands et gros theropode apparaissent dans ces régions. Et pas dans le nord

I would name it Megacuadalsaurus rex, translated to Big Tail Lizard King. Love you videos. Im currently try to use other therapods like carcharodontosaurids and megaraptora and 2 other genera tyrannosaurus for lols, and saurophaganax (my favourite along side Ceratosuchops and deinocherius) cuase of it possibly an ancestor to Carcharodontosaurs
Baryoreios (Bary = heavy, oreios = mountain) would be a cool name. Even if it isn't a Megatheropod
20 tonnes is soooooo much bigger than the max current understanding for this body type after all these years, it just isn’t realistic
Lembre-se meus manos e manas, esse fóssil é fragmentário, essa criatura pode ou não ser desse tamanho. E é mais provável que não.
Probably the only reason I watch these channels is because I know you are the kind of nerd that will directly take a look at the study and not just relay the click bait news from whatever garbage and clickbaity paleonews we usually get elsewhere.
Thanks you for doing that.
I remember when Spino and Giga were 20 tons.
and when giga were the most intelligent of the giant theropod
@@BrendonjacobDedaceI honestly never heard of that. I heard claims about Velociraptor being considered intelligent but back then the assumption is that most big predators are doo doo brain
Any 20 ton therapod is going to be next to immobile unfortunately. The T Rex is already shown to have been struggling at around 10 tons, IMAGINE DOUBLE THAT.
Giga never was 20 tons, only Spinosaurus fanboys were obsessed with such nonsense.
@@myusername3689 and the T Rex is on the bulkier side. Other mega theropods like Gigantosaurus or Carachodontosaurus are much skinnier
So if this were any other type of theropod; what do you think the size assessments would be for it like if it were say an Abelisaur or a Megaraptoran?
Gomez works. It's in the long tradition of giving giant theropods the most unintimidating names possible and I love that trend.
Wise words, Dr. T!
Lol yeah, but no usually Brazil and Argentina give cool names to their dinosaurs, it's Chile the one that gives the most horrible names
I'm from Brazil and I live in the Northeast. It would be a great surprise that one of the largest known theropods lived here, unfortunately my country does not invest properly in paleontology field research, it is a shame.
But the t rex is the biggest
Doesn't Bahariasaurus have longer dorsal vertebrae than Sue as well so maybe it's similar to that?
I'd probably name it Invictus Rex interfectorem: the undefeatable king of the killers.
Terribly edgy name for a bone fragment
@@PastaCool That's only assuming it's an actual carnivorous therapod dinosaur.
They should name it Neoedsonraptor Rex in honor to the king Pele. Sorry, could not resist.
1.Basically I am not convinced by the estimate that based on fragmentary material. Although if said creature was really a Carcharodontosaurid,I would like to name the species after Incan deities. It would more thrilling if the fragmentary material came from a Megaraptora.
Edit:
2. As some replies here wanted to name the dinosaur after Godzilla,I am curious about Vividen’s thoughts on Kenneth Carpenter’s thought experiment in 1998,in which he tried to classify Godzilla as some Abelisaur or Ceratosaur “Had Godzilla was a species of Theropod dinosaur.”
Many of the dinosaurs that we found were killed in events such flash floods or died in tar pits.... Meaning that many or most of the dinosaurs we found died prematurely ..... Knowing that many of them kept growing for their whole life, we could assume that certain specimens, that had a longer life than those who died prematurely, would eventually reach bigger size and may never be discovered....
I doubt the 20 tones, especially since we don’t even freaking know what it is.🤣
as soon as I saw the length of the bone compared to acro I audibly went "0 percent chance this is a carcharodontosaurid".
I refuse to get my hopes up about this shit, COMPLETELY personal stance on this is that I do not at all think this will end up being a theropod, but it would be cool if it was
Ah shit, here we go again
Brazil mentioned???????
" the biggest carnivore the world has ever seen "
Thats fossil is to fragmentary, they don't even know what it is. I,d take that with a huge grain of salt 😂
Agreed
What if there's a giant mammals lived with dinosaurs
Well, I had coffee with Gomez the other day, and I can totally confirm he was not a giant!
it should be called Lustianisaurus after the fact that Portuguese is called lingua Lusitania in Latin, but also because of the giant ship called the Lusitania that is also the lesser known forgotten giant ship tragedy
I believe in the potential 16.8 meter length of this theropod, by calculation!
I would totally name it Savrasaurus (respective to the giant tail verterbrae discovered) its name meaning High vertebrae lizard
I don't find it super surprising if there were T. rex and beyond sized theropods throughout history, what with the size of some of their prey.
Anyways I'd name it Jeff
I remember this is a big deal and everyone is talking about it, and its been 7 months
Imagine what is buried in the untouched regions of south America
Did this new theropod live at the same time as tyrannotitan? Just curious. Mike
If it is indeed a carcharodontosaurid, I would guess it is in the same size range as Mapusaurus and Giganotosaurus, so probably a 40 foot animal. Massive, but not astronomically huge.
Probably bigger than both Mapusaurus & Giganotosaurus. So it's in the 50-55 ft range & 15+ tons
Keeping in mind that the skeleton is fragmentary, I just love gigantic dinosaurs, both theropods and herbivores.
_pressing X to doubt_
Me too bro
Brazil mentioned.

This is how I feel about this estimate. (But I would pleasantly surprised if it was even over 15 tons.)
If this does somehow end up being accurite, I can't wait for the universe the adibly bend and creak just to spawn a 21 ton trex skeleton as it seems to do every time anything bigger is found
