This Brazilian Theropod May Have Been The Biggest Ever... If It Was A Theropod At All

  • It seems like every few years the news cycle explodes with another new giant theropod set on dethroning Tyrannosaurus. The 90s were full of giant carcharodontosaurid hype and the early 2000s had Spinosaurus as their sweetheart. In 2024, Tyrannosaurus appears to be the reigning champion with its biggest representatives at 10-12 tonnes--but a new challenger approaches, this time from the Early Cretaceous of Brazil. Will the tyrant lizard king’s claim to the throne last?

  • @The_Story_Of_Us
    @The_Story_Of_Us 6 หลายเดือนก่อน +70

    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.

    There are also some random isolated toe bones of T.Rex that ought to have belonged to stupidly large, far bigger than anything else we have, BUT again, way too fragmentary.

    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.

    Ah, yes! Another contender for the "Overhyped biggest theropod who turns out a lot smaller in real-life" awards. Spinosaurus was hyped as the T-Rex killer in JP3, then turned out to be Crocoduck a couple of decades later. Giganotosaurus was hyped to be double the size if T-Rex in the Ark games, just for it to be discovered that T-Rex is bulkier/heavier than it.

      En fait les deux premiers spécimens giganotosaurus sont plus grands et plus lourd que les deux premières spécimens de tyrannosaurus rex donc il est encore possible que si ont fait plus de recherches sur giganotosaurus et sa formation d’origine et qu’ont découvert plus spécimens il pourrait s’avérée que giganotosaurus soit belle et bien plus grand et plus lourd que tyrannosaurus et même choses pour spinosaurus car la représentation crocoduck soit en faite plus semble a un Suchominus avec une queue particulière et une voile a 1/4 de sa longueur faite avec une basé musculaires donc se que je veut dire par la c’est qu’il n’est pas complètement sur que tyrannosaurus rex soit le plus grand theropode et il est donc possible qu’il existaient un theropode plus grands plus massif que t.rex

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 ?

    • @neptuneai8168
      @neptuneai8168 6 หลายเดือนก่อน +41

      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.
