10 Ton Theropod! New Study Breaks Dinosaur Size Limits
Vložit
- čas přidán 27. 08. 2024
- Giant theropod dinosaurs like Tyrannosaurus rex and Spinosaurus have always captivated the imagination of paleontologists and the public. A new study on dinosaur size, Larramendi et al (2020), indicates that previous size estimates of extinct animals, including theropod dinosaurs, may have been too low due to errors in the measurement of specific gravity. This video explains the meaning of specific gravity, how it affects dinosaur size, and if a 10 ton theropod is physically possible. Spinosaurus, Tyrannosaurus, and other megatheropods like Carcharodontosaurus, Giganotosaurus, Tyrannotitan, Deinocheirus, and Mapusaurus are all bigger than previously thought!

Also, yeah, I've also discovered that Mapusaurus was surprisingly long and heavy. It was bigger than Giganotosaurus.
It stunned me to research how Mapusaurus had gotten buffed when I got back from my mission! Carcharodontosaurids are monsters.
@@TheVividen Agreed . There's a reason why they're sometimes called "Allosaurus on steroids" ;)
How big is mapusaurus now?
@@nosimpsallowed1566 Most sources nowadays say that Mapusaurus was 12.6 meters long. This is based on a fibula (MCF-PVPH-108.202). I've obtained 15.0 meters for that specimen when comparing it to Tyrannotitan. This is my measurement, so take it with a grain of salt. If you want a source for the 12.6-meter estimate, the most recent paper giving it is Canale et al., (2014) (Figure 1). Mapusaurus also had a wider pubis than Giganotosaurus, which would've made it heavier. Basically, take the highest weight given to Giganotosaurus and multiply it times 2.

@@Bullboy_Adventures Especially not with my new paddle tail!
@@Bullboy_Adventures when there are more chances of Spino on land (Carcharo with the bite on that spino sail fossil says hi) than T-rex in water.
@@ammonitetheseaserpent3761 T-Rex "Oh yeah? How's leg day treating ya?"
@@Nature_is_metal Explain how Spinosaurus has a higher chance to win on land than T. rex in water. Literally T. rex and Spinosaurus both exploit each other via out-flanking in a similar ratio in speed in land/water. If Spinosaurus starts tearing at a T. rex, it first needs to avoid its jaws. A T. rex would be restricted to a doggy paddle, but a strong thrash could possibly muscle that grip from Spinosaurus off or thrash in a position to swim and crunch a vital area of Spinosaurus in an in-line angle.
As for the Spinosaurus withstanding the bite of the Carcharodontosaurus, there are some things to mention...
1. The spine was broken. This would have done some lethal damage to Spinosaurus’ spine. Being a predator, Spinosaurus likely retreated after withstanding such an injury to heal the wound off. See, the application of a fight like that would result in the predator instinctively retreating to heal the wound so it wouldn’t die. Combine that with the fact that Carcharodontosaurus had serrated teeth made for bleeding + slashing and tearing off flesh, and that just rather supports why the Spinosaurus likely was the one to retreat in that fight because of blood loss.
2. Position
Considering the fact that the Carcharodontosaurus was biting the enlarged spine, it clearly represents that Carcharodontosaurus was the one in control in that fight. The Carcharodontosaurus seemed to have out-flanked Spinosaurus’ claws in order to bite the spine. During which, the evidence shows that Carcharodontosaurus was being superior in that fight.
3. If a T. rex would bite the Spinosaurus’ spine in that position, those bones wouldn’t have merely been broken. No, those bones would have been crushed into a shattered, non-healable, and gory pulp.
On land, T. rex can literally do 3 things to end the battle right then and there...
1. Rear up and crush Spinosaurus’ skull.
It’s as simple as it sounds. The T. rex just needs to rear up and clamp down on the skull of Spinosaurus. This act would likely be instinctual since T. rexes are known for face biting. If this happens, the Spinosaurus’ skull bones will essentially be crushed as it will die.
2. Rear up and crush Spinosaurus’ neck
This is almost the same as the previous entry. All the T. rex needs to do it rear up and bite the Spinosaurus’ neck. This position (Assuming a clamp just under the skull or in the middle of the neck) would leave T. rex’s neck out of reach for Spinosaurus’ claws (Claws supported by arms that are limited in articulation, mind you). Even if the T. rex clamps down on the Spinosaurus’ neck where the neck is in clawing range, the T. rex will likely only sustain a claw or two. The claws are strong, but the immense muscles and bulk of T. rex’s neck could withstand at least one claw to the jugular, and probably a good amount of claws to the sides of the neck (Areas away from the jugular). Oh yeah, and this is assuming that the Spinosaurus is alive to achieve such lucky claws when the T. rex bites down. If the T. rex bites down, it will be over quickly. I wouldn’t be too surprised if the bite was too sudden for it to even be alive to claw T. rex quick enough.
3. Out-flanking Spinosaurus
In this scenario, the T. rex essentially can maneuver around the Spinosaurus to access the side of the neck. Thanks to Snively et al. (2018), Tyrannosaurids, Tyrannosaurus rex included, were concluded to have the agility and maneuverability of a smaller Theropod of half their size. A T. rex of the 8 - 9 metric ton range could maneuver like a smaller Theropod of 4 - 4.5 metric tons. T. rex would be very capable of out-flanking Spinosaurus, especially if the Spinosaurus is in a reared up position which really hinders its already limited mobility to an even worse extent. T. rex can swiftly maneuver around the claws and to the neck where it can clamp down + pulverize bones. T. rex has an overwhelming winning majority of chances on land.
The Trex at that size would of truly been terrifying, it would of made deep humming sounds in the night as it slowly hunts its prey.
Probably some real nasty roars as well.
@@Xenosaurian

@@vesuvius115 ur comparing plants to dinosaurs😂 do u think of that
This is what I love about paleontology. Just when we think we contently know something for sure, a single new discovery can come along and re-write a major portion of the entire subject, if not the whole thing, demonstrating how life from the past is likely well unlike all of our expectations and current beliefs. Give it another few decades, and I expect dinosaurs will change even more wildly than they have from the 1990's until now.

One of the coolest theropods!
I'm not surprised! If you compare the cavities of all theropods based on the skeleton (rib cage and hip width) alone, T-Rex is the most hefty boi. One guy even argued with me that Spinosaurus is heavier because it doesn't have hollow bones unlike most theropods.
That guy is in denial of the fact that having more mass in your bones don't help if the T-Rex is literally a lot wider than it (most of the Rex's weight is not on the bones. Not to mention that proportionately, hollow bones only consist of 7-8% of an animal's total weight as compared to 15% for those with bone marrow.
I hope that guy shows up in my comment!
@@tnb4509 Tbf, if Nizar finally found a Spinosaur fossil that exceeds the Record T-Rex in size and is at least 50% complete, then I'll respect it a lot more. Not that I hate it to begin with, just the hype around it. Sorry for sounding rude, I just got overexcited over this news. I still have no hard feelings towards you. Can't say the same over the other fanboys.
We don't have any complete adult Spinosaurus aegyptiacus specimens. We have 3 fragmentary specimens which depending on how they are interpreted weigh from 8 to 14 tons. Whether Spinosaurus is heavier than Tyrannosaurus is still unsure because of the fragmentary nature of the former.
@@tnb4509 Well you can say T. rex is the largest well understood theropod, but yeah I think crowning Tyrannosaurus as the king is a bit preemptive.
@@tnb4509 "I'll defend any dinosaur that's being underestimated"
There is nothing underestimated about the Spino, there is just facts, and the fact is that TRex was heavier and stronger, and would defeat Spino in a fight.
"it's just that T Rex is usually the one being OVERESTIMATED."
Again, facts don't care about your feelings, the TRex is the heaviest and strongest theropod up to date, if hearing that hurts your fragile ego then there's no reason for you to learn anymore.

What about Small dinosaurs?
Well using the size difference of sue and Scotty (408 kg) and the new mass and density (801 kg boost) Scotty is really 12.258 tons ! And well there’s a new T. rex in the block, Victoria the T. rex and she could be bigger than Scotty
Wait Scotty is 408 kg heavier than sue + the new mass/density boost = 1,209 kg so if we add that to sue’s weight ( getting Scotty’s true size) = 11,120 kg… if this is wrong then please tell me. Unless we probably have a 12.258 ton T. rex on our hands.🦖📏🤯 and sorry I kinda said this again 😕
Mind you, Franoys' MSNM V4047 is not based on the new reconstruction, so I think it might challenge Mapusaurus for second place once the new tail and other mass differences are accounted for
It has the potential to exceed Mapusaurus. One of the 2020 authors stated Spinosaurus was likely much heavier than 6 tonnes. Stay tuned.

Wasn't Ibrahim himself have had said that the Mass estimates about Spinosaurus are highly under calculated ?
From what I understand, in a tweet he mentioned a 10-12 ton mass for Spinosaurus and said that methodologies for estimating theropod masses usually result in underestimations. However, the model he used (Ibrahim 2020) has been criticized for being unnaturally bulky, while GDI is widely regarded as a more accurate method of volumetric estimation. The dust is still settling on that particular debate, but for now it's more parsimonious to accept GDI estimates since their model is so controversial.
@@TheVividen Alright I looked it up appearently he mentioned it thought a question asked via Reddit (on his official page)
I looked it up and the 10 to 12 he gave those estimations as the maximum however, he made apparent that the Spinosaurus could attain 8 to 9 tons
However its agreeable that 5 to 6 tons is (at least for now) are rather underweight as based on the latest consensus
@@thedoruk6324 Yep, with the new densities the biggest specimens exceed 7000 kilograms. And given the paucity of complete specimens, I wouldn't be surprised if Spinosaurus pushed 8000 kilograms with 9000 for an exceptionally massive individual.

Wonder if they could apply to marine reptiles probably not. But I got a question for Hadrosaurs, what NSG are they?
Great question! On page 34 of the study, the authors wrote "the SG of most ornithischians should have been comparable to extant mammals because of their absence of skeletal pneumaticity, contrary to Paul (1997, 2016) who applied a 0.95 NSG to the group. In general, species lacking armor would possess an NSG very close to 1.0." So ornithopods would fall into that group.

I'd say the best title would be dinosaurs getting heavier, people would think "bigger" as taller and longer, and the thumbnail doesnt help at all
Mapusaurus is larger than Giganotosaurus on this chart probably because they are not taking in consideration the mucpv-95 Giganotosaurus specimen, I know it is basically a jaw fragment and it could just be some centimeters longer but the smaller mass estimate would be larger than the previous for Mapusaurus, besides the 13,2 meters long Giganotosaurus is still plausible and in this case it certainly would be much heavier.
Because ONE fossil fragment isn't enough to draw any conclusive estimates because specimens of the same genus and similar size will often have varying bone sizes from each other.
I know that with that few material is difficult to make size estimates but for what I saw it’s still would be a larger individual.
@@marcosabbade5665 What you saw is a single lower jaw fragment, so there is technically zero evidence that it was bigger. Like I said, individuals of a similar size can still have certain bones that are bigger or smaller than the other. Heck, I’m a good 5 inches taller than my dad, so I basically tower over him, but he has a bigger head than me.

Mapusaurus- 12.5m
Tarbosaurus-11m
Etc
Length is far from being size

I don’t think Scotty is the largest T. rex Victoria the T. rex is bigger
I was only impressed by the theropod boosts, because I think sauropods were way heavier! Ex: Giraffatitan can reach 65 tonnes!
Neutral Specific Gravity - Did Einstein invent that? :)
Next we'll get the Theory of Tyrannosaurian Relativity: Whenever a megatheropod's mass estimate increases, T.rex automatically receives a new study that buffs it proportionally.
@@TheVividen You lost me with the technical specificosities - but I'm still excited!
The isle t rex
Lets see if they find another specimen for my boy Carcha, I always saw Carcha bigger than the rest charcharodontosaurids. Also what about Ibrahim's new weight estimates about Spinosaurus that go up to 12 tons?
Carcharodontosaurus while big was surpassed by giganotosaurus and mapusaurus in size
There isn't! Ibrahim's a well-renowned Paleontologist but that "12-Ton" specimen isn't even properly researched yet. As far as I know, it's still an unsubstantiated claim to hype up his discovery. Don't forget that when Spinosaurus, Giganotosaurus and Carcharodontosaurus remains are discovered, those who discovered them are quick to claim that said animals are "bigger than T-Rex", "new king of dinosaurs", "largest meat-eater", etc... despite lacking as many fossil samples as Rexes.
I wouldn't blame them though! Fanboys all over the worlds are itching to have the T-Rex dethroned as the largest theropod. If I ever discovered a similar-sized dino as a T-Rex, I'd make the same claims. Easy marketing!
@@mstr293 Exactly! Spino fans are itching for the day when TRex is dethroned, and that day will unfortunately never come for them..
