- What are the limits of terrestrial animal size, and did sauropod dinosaurs reach those limits? was the biggest land animal ever? While it was likely a sauropod dinosaur, is there a way to determine how big it was? This video combines months of research and assistance from sauropod paleontologists and biophysicists to calculate the size limits of sauropod dinosaurs, the biggest land animals in the history of the world. The biggest living thing, when it comes to land animals, would have been a sauropod dinosaur as big as a whale. Giant sauropods like Patagotitan, Argentinosaurus, Brachiosaurus, and the lost giants Fangorn and Maraapunisaurus are analyzed. Thank you to Arianna Harrington, Brian Curtice, Ray Wilhite, Mike Taylor, Matt Wedel, Brooks Britt, Rod Scheetz, Carrie Leavitt-Bussian, and Justin McKee for helping out with this months-long project.

When your reference list is an essay of it's own.
Well done man! Referencing stuff already is very annoying and a lot of TH-camrs don't do that. You are doing incredible job going the extra mile
how big would a theoretical Sauropod have to be to feed from a Giant Sequoia?
Your reference list far outdoes my TH-cam videos. Nice job with everything. Mike
Interesting and informative video! One thing I am curious about is whether the Argentinosaurus specimens currently available are full grown or subadults. If they were subadults, would it be possible to then use known growth rates of other sauropods to estimate how much growing the specimens had left and therefore how big they would have been fully grown?

Best part is, that name is fully possible.

That size is ♾️
The largest sauropod, whatever it was, would've been a walking mountain among the walking mountains that are sauropods. Would literally be a real life kaiju. Great video and calculations!
We know it bruh it argent
@@pierre-samuelroux9364 argentinosaurus is the largest we KNOW of, there could be way larger ones we have not discovered yet, Sauropods don't fossilize well from what we can tell.
@@Turkeynuggies oh
keep in mind that brachiosaurus displayed both around chicago and other places is a sub adult...and so is the Berlin specimen...isolated bones could reach 7ft in larger specimens and there photos to show this...
@@pierre-samuelroux9364argentinosaurus is the largest defined species that we KNOW OF
Now this puts the "Titan" in "Titanosaurs". I don't think we will ever be able to comprehend how gigantic a max sized sauropod could possibly have been
Until we invent time travel
We just need to get more reasearch and find more skeletons
You could never get that off of fossils , remember they are rare and you would be lucky to get a creature in the top 70%
The fossilisation bias usually means that most fossils would be of smaller and younger animals.
I think a more accurate size can be obtained if we determined how big of a sauropod can an environment support.
50 ton sauropods can live in herds.
But truly gigantic sauropods would be solitary as no force on earth would be able to hunt them.
Like even if humans existed they couldn't harm large sauropods until the late feudal age.
@@loowick4074 I mean pitfalls exist, and for such a large animal to lose its footing or stumble and fall down would be a death sentence although due to their immense size I doubt early humans would actually try messing with adults.
Really interesting research. Can’t wait to watch the EDGE version of this next week.
It'll have the exact same transcript but only slightly altered
@@RandomCrapIUpload lol fr
It'll just be plagiarized
This might be an unpopular opinion but I think Sauroposeidon is criminally underrated. The tallest noodle neck of them all. 🦕
Also the coolest name of any dinosaur.
highest estimate for it was 65ft height 100ft long...some lower estimates put it at 50ft high ...
@@jackstraw4222 Really? The highest I saw was 67ft high and 112ft long.
It's extremely difficult to know exactly how tall a given sauropod was, given how heavily that relies on neck posture. The idea that it was the tallest is based on a vertical head posture like Brachiosaurus, but we don't know for sure which sauropods were capable of that or not. In addition, even with a less angled head posture, the absolute largest megasauropods may have been taller. We just can't know for sure.
It will never cease to amaze me how these creatures actually existed. It feels like a fantastical group of creatures and they are but, to just imagine their existence boggles my mind sometimes on the scale and success of these animals.
I want to be a paleontologist so bad… I’ve wanted to ever since I was a child, but I’m now 30 and never went to college (couldn’t afford it) and pretty much barely made it out of highschool
I am sorry for you man
Its the same for me.
Become a paleoartist. It's basically being a paleontologist minus the mandatory degree!
Volunteering at the right place can get you almost there.
Very familiar
As years pass, we discover even more stuff that show how successful dinosaurs and other prehistoric animals can be. Who knows what we will discover about Sauropods in the future, but that will be ready to grace us with more information about these titans. What a great video!
Imagine how thicc a hypothetical 600 ton creature would be.
Look up "broome titanosaur".
GODZILLA is about 800 Tons‼️
@@treystephens6166 Depends which version, and likely what is depicted in the movies, even Minus One, would weigh a lot more than that. The square cube law is brutal, I'm not sure who estimated 800 tons, because he'd need to be a lot heavier than that.
@@mikerude5073 I think He was supposed to be 800 Tons in GODZILLA (1984) 🇯🇵
modern godzillas are in the double digits of thousands of tons, but I wouldn't be surprised if one godzilla was 800
nice video, would be insane to find a sauropod one day that is over 200 tons, i have a question, do you believe aust colossus could be a real genus of ichthyosaur?
The aust colossus is objectively a real genus of ichthyosaur (or species of an already existing genus). The size is just uncertain.
yooo congrats on presenting this at the conference that’s gigantic and amazing feat
Love these type of videos!
Been waiting for your next video. Thanks for what you do. Mike from Prehistoric Magazine
Thank you, Mike!
@TheVividen hi 👋,why in restorations big sauropods and other dinosaurs include tyrannosaurus no Robert Wadlow? either tallest human ever is too big or theropod and other dinosaurs won't seem big anymore.
1:57, that is incredible!
Fascinating video. Megasauropods are a fascinating subject and your discussion of biomechanics, evolution and ecosystem limits present an interesting look at sauropod sizes.
No matter how large those estimates are, i don't think any animal will beat the weight of the 33m blue whales from the 20th century, 250 tonnes.
Truly great work.
Really amazing research! That was interesting to hear theoretically that sauropods could grow that large!
A 600 ton sauropod would be extremely shocking yet totally bs
150 tonnes is the maximum estimated weight of any land creature. Seismosaurus, Maarapunisaurus, Bruhathkayosaurus estimations are even larger than Argentinasaurus.
I'm sure we said the same thing when we discovered the first sauropods.
"It is not possible that something so heavy could walk on land. Surely everyone walked in swamps to be able to carry their weight."
We certainly do not fully understand the biological limits for size in animals every time we think that yes, something changes that thought.
@@BaldianOfIbelinyou also like to say similar about technology, right? And about physics too?
You'd love to say statement like:
"We thought flying is impossible " ... huh?
I'm sick of comings across members of general public keep disclaiming that , like its a natural flow of humans to wrong , only then right...
Melodrama....
Yes, there are things that changed our initial prediction. BUT there are much more things that stay as laws of nature.
We've come so far in our observational capabilities and equipments that theorising something wrong is becoming more and more slim. Not like we'll never fail to realised a true nature of something. Of cuz misinterpretation and etc. could happen thru the future. But not like it's happening all the time. We literally put couple giant telescopes at the lagrange point, and we've built a town sized particle accelerator too!
Please don't tell me you believe we will one day able to push matters into faster than light speed ... PLEASE im begging you.
Also id like to ask one thing: what is the probability of us human realising the true nature of something at initial observation/ experiment/ field test/ etc. ?
Or do you out right believe truth itself is changing !!?? 😮😮
O my
@@thureintun1687 Obviously there are limits to everything, I never said there wouldn't be one.

Awesome video as always good sir.
Very interesting. Thank You
Amazing. Sauropods are fascinating animals that lived millions of years ago and got to VERY LARGE sizes. The estimates in the video (Based on what I think) are very believable (For now, anything can change). I have been trying to calculate the size for Sauropods for around a year (I'm not a Paleontologist yet, but, I can still do stuff like this), I personally think people should also consider the fact that Sauropods might have gotten so large due to other Sauropods competing. This doesn't apply to all Sauropods, but it's still possible, Theropods and other non-Sauropod Dinosurs are mainly the reason why Sauropods grew to these sizes. Finally, I love your work and I hope you have a good day.
I'd like to imagine the upper sizes of the largest birds and crocodile and compared to their average species sizes would be just about as close to the proportional maximums for dinosaur genera, so I'm referring to proportions like that of Gustave compared to an average Nile crodile being possible for any dinosaurs given perfect conditions.
Anyways, your video was amazing, the presentation and explanations were great and easy to understand, 10/10 video, would watch again
incredible video
Thank you for this video. I absolutley love sauropods
I wish I could give you money, so much hard work for a 7:24 minute video. Sadly all I can give is my appreciation and watching the ads, so thank you

@@yissibiiyte the T. rex is the maximum limit of the large theropods.
@@rodrigopinto6676 according to which studies? I'm sure a charcharodontosaurid could theoretically evolve to become bulkier. Gven it's already taller and longer than a rex, if it bulked up it could become heavier.
Interesting 😮
Someone named a Sauropod Fangorn! Yes!
Imagine the farts from such an animal. Probably enough to knock you down and make you deaf.
Speaking of Camarasaurs I got to view some of their trackways this weekend. Diplodocus and Allosaurus as well. It was rad. I have a lot of cool morrison foundation sites near me.
Why hasn’t there been a Kaiju movie that uses Sauropods as the main stars. It seems like a massive missed opportunity.
to be fair godzilla moggs even 600 tons sauropods, he weight about 100 000 tons
to be fair godzilla moggs even 600 tons sauropods, he weight about 100 000 tons
Could you do a video about how much would dinosaurs weigh if they were as massive as mammals??? That's quite an unexplored topic
Any news on the Bertha Rex? I like my C H O N K E R Tyrannosaurus. Also, I saw the size difference between the ‘Leviathan’ Saurophaganax size an the average Snax. I then applied the same logic to a Tyrannosaurus (doubling weight estimates) and found that at the very least, using this method gives you an animal around 15-16 tones. But if you double the bigger estimates, you can get a 20+ tonne animal. How cool is that? A tyrannosaurus that rivals paleoloxodon in size!
The bigger estimates are the larger than average animals.
There was literally a paper last year that makes it clear T.Rex maximum theoretical is around 15-16 tons.
Still huge.
Amazing, I personally believe that Tyrannosaurus Rex (Maybe even the whole Tyrannosarus genus since THERE HAD TO BE another species of Tyrannosaurus) could have reached a maximum size of 13 or so tonnes. I got these results by looking at previous Tyrannosaurus estimates, then looking at the anatomy of Tyrannosaurus. I also looked at Tyrannosauru's ecology, I then looked at many Tyrannosaurus Rex specimen's femur circumference. @r.k845 "T.Rex maximum theoretical is around 15-16 tons" is a amazing response since bipeds like Theropods can only support so much weight, while quadrupeds like most Sauropods and Elephantidae, can support their weight thanks to their four legs and many more reasons. @SamuRhino2023, I'm not saying your wrong, I'm just sharing my personal thoughts and opinions, you did something good.
@r.k845 “Theoretical maximum”. Like he says in this video, it’s foolish to think we’ve found the largest specimens of any extinct taxon.
@@SamuRhino2023 The common Rex is around 9 tons. The largest discovered is 12 tons. The largest in theory is 16.
Makes sense.
@r.k845 I know, and it does. But theropod sizes can be questioned a lot more lately mainly because of a Saurophaganax specimen that was double the size it was supposed to be. So a Rex bigger than 16 tons is likely I’d say, but not common. And a Rex that big likely would have different proportions and would lack in speed and agility in comparison to the smaller estimates. Most Rexes were between 8-10 tons yes, but the larger sizes are not only fun to think about, but very well a possibility. I’m not saying they could get Argentinosaurus sized, lol that’s just silly.
I want a video about the theoretical maximum height from ground to head for the tallest sauropods
Could you not fit a Gaussian or skewed distribution to the mammals at least and use that to find the 1:1000 specimen or whatever standard deviation you pick as likely to have occurred? I don’t know the distribution so maybe there is something difficult with a power law tail or something
👍🏼👍🏼👍🏼good for you!!! 🎉
Love James Gurney, but look up Todd Marshall for some great Paleo-Art!
What body plan would a 600 tonne land animal use? Something slug like, with many culumnar legs underneath?
Cool.
if fangorn specimen was as large as the higher bound estimates, then i think it would be "possible" to get somewhat close to that 600 t mark though probably not quite reaching it. We have limited resources though, unfortunately. This is not only a problem with extinct animals though, even MODERN animals we are limited on what we know as the max size for them. Many "max" accounts for modern animals are unreliable records, making doing the same for extinct animals even worse.
Also only 0,1% or less of all animals including sauropods and other living organisms ever existed can be discovered
Any news about Bertha?
sorry i am quite late so my question is if the largest hypothetical mass for a land animal is 600 tonnes what would be the largest hypothetical size for a sea creature i dont know something like 1000 tonnes ?

@TheVividen what is your thoughts about the infamous indian sauropod called Bruhathkayosaurus. There were news about it that could suprass even argentinasaurus itself. Is that true ? Or possible ?
He already discussed this
Is true because Molina Perez and Paul estimate that average mass body of bruhathkayosaurus is 110-130 tons,while average body mass of argentinosaurus is 75 tons
@@user-rw4yi2xw5i thanks!
An off-shoot of this question: How big could a sauropod get ecologically speaking? As in what would the size limit be before the animal starts starving to death
I guess it also depends on terrains and food source, but I would guess the maximum upper limit would be around less than 70 meters and approximately 90 metric ton. Go higher than that and I think the poor dino would collapse under its own weight (square cube law) before it could even starve to death
I don't know how much such a creature would need to eat, but let's say it is 5% of its body mass per day. Now, a 600 ton animal would need to eat 30 tons. Assuming a density of 1 ton per cubic meter (basically water), the upper bound for the volume of food would be 30 cubic meters. Or let's make it an even 27, such that it would be a 3x3x3 m cube of food.
Now, that sounds like a lot, but if you have ever removed weeds from a garden, you will find you will easily remove a cubic meter per 2-3 weeks from even a small garden.
I think the problem would not really be the available biomass, but it would more likely be the required time to chew and swallow 30 cubic meters of vegetation
per day. You would be eating non stop, I guess.
Interesting, great and patient work, thank you.
I am no palaeontology expert, however... I think it is not unreasonable to assume that the biggest Sauropod specimens could reach 100 tons. Which is stil staggering.
but things can be heavier in the ocean no matter how big they get on land...thats why i still am holding out for even bigger marine reptiles to be found....im aware of the huge 3m long pliosaur skull in oxford...

@@k7l3rworkman97 I'm not talking about how large they did get, but how large they could get. So, before their muscles, bones, or wings aren't strong enough to keep them up, or to take off from the ground. The theoretical, physiological limit.
The large azdharchids like quetzalcoatlus and hatzegopteryx seem to already be at the limit. Any larger and they would need larger muscles to take off, which would make them heavier, which would require more muscles, and the domino effect continues.
@@yissibiiyte I'd think the limit was more, considering that domino effect is the reason they walk (and take off) with their wings.

We may not have dragons, but what we have, or what he once have, is equally as cool, lol.
If we did find sauropods that big then maybe theropods in that area would have been bigger to. Mike

Dreadnoughtus is overhyped/overrated, maybe because it's skeleton is more complete.
we will probably never see the skeleton of those larger sauropods with a some sort of hormone defect that caused it to grow big enough to cause organ failure
Skeptical. What would it even eat and it probably wouldn’t be able to afford to stop eating. Has anyone ever looked at its calorie requirement?
But could it defeat the Shapeshifting Spinosaurus?
All we need mext is a real life Godzilla💀💀
The largest African elephant weighed 12 tonnes and would have easily taken out a T-rex with little effort so yeah...by that logic we could indeed have a 140-ton Argentinosaurus freak specimen.
You high?
Bro do you know that might have a will might have a large pouch
An elephant weighs 5000 kg and eats 150 kg of food per day and it takes 18 hours ( every waking minute) to eat this amount
A saurpod weighs ten times as much.
That's the only type of dinosaur I don't believe existed. Because scaling up it should need *minimum* 800 kg of food per day and take 8 times longer to eat (so 144 hours in a 24 period ) to eat this
Unlike a whale which has a gigantic mouth and can sieve huge amounts of plankton at a time, also the water is supporting its bulk, cutting down drastically on calories needed to move .
A saurpod has a tiny head and is eating green leafy foliage which isn't nutrient rich.
Not only this but a saurpod lived in a herd among other gigantic saurpods also needing 850 kg of food per day.
A herd of these guys (even if it were possible to eat this amount which it isn't)
Would absolutely devastate the flora everywhere in a huge radius. Causing mass starvation to every other hebervore out there. Which would then also begin to affect the carnivores in a month or two.
I just don't believe saurpods exist and haven't seen anything to convince me otherwise.
And arguments like "saurpods had an efficient digestion" while it's purely hypothetical, even if it were true... Ut may bcut it down slightly. But its going to need to reduce its required food by way more than ONE FIFTH!!
And even then it would still not be able to sleep for eating and there would still be the problem of absolutely wrecking the habitat as it migrated causing havoc for the rest of the fauna.
Sorry but i don't see them scientifically existing
Maybe there was a lost food source in the past that could help the sauropods to exist in their gigantism.
There were many sauropod fossils found scince over 100 years, so it is clear that those creatures existed.

@@spongebombepicpants1073 so your logic is. "Well they existed and that's that. So there must have been a magic food"
Except we are in reality here. Not avatar or star wars
THERE'S NO PLANTS THAT CONTAIN THE SAME NUTRIENTS AS PLANTS ONE TENTH THEIR SIZE.
PERIOD.
Plants evolved to be MORE nutritious after the dinosaurs. NOT LESS. There is now fruit and vegetable biodiversity after the dinosaurs died out. Flirting the Cretaceous it was pre dominantly FERNS. Very low nutrients.
It isn't scientific to say well saurpods existed they were 100 tons so now all biology and all facts face to be twisted and forced to support that.
B.s.
And btw. Saurpods have the most fragmented incomplete skeletons of any dinosaur.
Their head was comparitively TINY COMPARED TO THEIR BODY
Most of the neck and tail bones eye missing.
It's therefore more logical to conclude they were smaller than they think. That instead think. Well gee there must have been a super mario magic mushroom and they only needed a few of them.
Total horse shi.t
An elephant spends 18 hours a day eating. That's how much food that large animal needs. Google it. Ask Alexa.
A UNIVERSAL FACT WITH HERBIVORES is that the bigger they are. The more INEFFICIENT. Their sustainability is.
A rabbit might only. Need to spend 30 minutes eating. A pig 2 hours. A cow 5 hours an elephant 18 hours a saurpod which I calculated mathematically based on weight needs 144 HOURS PER 24 HOUR PERIOD!!
and WITH TINY HEADS FOR THEIR SIZE
If you think we'll there must have been a super food which cuts down their food intake to like 10% that amount. That's Disney fictional garbage.
I believe all dinosaurs EXCEPT saurpods are possible
❤
*Input Gigachad theme song:*
To fight Godzilla that’s why
Dont ever stop talking about biggerer sauropods
personally i believe the true maximum size of sauropod still less heavy than the largest blue whale
The death of such a beast would be comparable to whalefalls!
Anyone remember Amphicoelias ?
Maarapunisaurus
So just a below average sized Argentinian sauropod?
If I had to choose the name of a sauropod that exceeds 100 tons, I would choose the name "Thronusargon giganteus", which means "Legitimate King of the Throne of Giants"
I m just like nature,because only nature can make truly titanic size objects,and no one man made object or another conception cannot reach to those titanic scales to which only nature can reach
I thought that GODZILLA is the BIGGEST ⁉️
Too bad nobody took pictures of the dinosaurs when they were around.
Damn boi he thicc
I think lumping genders to ignore sexual dimorphism is going to skew your results. When you use a species which is highly sexually dimorphic as an example, it's maximum to average ratio is going to be much higher because the maximum is for one gender (the larger one) while the average is pulled dramatically down by using both genders
I really hope that we eventually discover a sauropod genus that averages 100 metric tonnes.
0:51 oh my science!!! Peer reviewed studies back up this!!! Oh my fauci
The biggest land animal that we know of is the argentinosaurus huinculensis they got up to 30meters long and up to 84 metric tons thats more than 80 allosaurs
Magyrosaurus is one of the smallest sauropods ever getting up to 20 feet long and 2200 pounds making it around the size of an average allosaurus these dudes coexisted with the largest animal to ever fly Hatzegopteryx Thambema yes its bigger than quetzocoatlus funny how hatzegopteryx stood up to 10 feet tall and weighed as much as a brown bear
This is a magnificent, albeit brief, presentation
It's light years ahead of the typical TH-cam¹ video
The adherence to scientific methods and analyses is stunning and incomparable
This ranks among the top 5 pieces I have observed in 10 years visiting TH-cam
Extremely well-done, young man
For the record, I hold 2 REAL undergrad degrees in Chemistry and Physics
And a REAL graduate degree in Abstract Mathematics
