" Barosaurus was an enormous animal, with some adults measuring more than 26 meters (85 feet) in length and weighing more than 20 metric tons (22 short tons).[2] There are some indications of even larger individuals, probably over 50 meters long and with a mass around 100 tonnes making it possibly the largest known dinosaur.[3] Barosaurus was differently proportioned than its close relative Diplodocus, with a longer neck and shorter tail, but was about the same length overall. It was longer than Apatosaurus, but its skeleton was less robust.[4]"

Thus Barosaurus seemed to be built like an diplodocus: very long body but light frame.

Argentinosaurus would have been 35 meters long and weighed 80 tons. Bruhathkayosaurus 34 meters long and 90 tons. Built like the apatosaurus they seemed to be more robust animals. Other dinosaurs seemed to enjoy the same frame: brachiosaurus, paralititan, sauroposeidon... Als were titanosauridae.

I know that, mostly of you don't like wikipedia but we are just speculating from a few bones discovered. Thus no reason to get excited about them and drag some definitiv judgments.

Diplodocus was a "slight" sauropod, but if he could use its tail like a whip, the blow could be fatal for any predator. If I say that for a diplodocus, as concerns the bigger sauropods it was even more true. I truly think that adult sauropods couldn't fear any predator, except perhaps if they hunted in pride, but even so they should have prefered to attack a juvenile one or a wounded adult...

I personally think those robust sauropods are much heavier than gracile sauropods such as diplodocids. It's like comparing elephants to giraffes.

Not quite. Barosaurus and Supersaurus are 'gracile' sauropods, and they are pretty big (35-40 and 100 tons)

@Spalea 
Well, not quite. Mamenchisaurus is actually quite a robust animal; it weighs about 3.5 times as much as Diplodocus at length parity, and in fact outweighs a 34-37 meter Argentinosaurus by 2 tons (35 meters, 75 tons). So yes, I think we can put it as robust

OK, if you want... I only see that accoding the sources, the data and conclusions are quite different. In short nothing definitive yet. Reply

I'm very surprised about this, but it seems Mamenchisaurus sinocanadorum might not be Asia's largest dinosaur after all. That title may go to Ruyangosaurus giganteus, which is 31-36 meters and 100 plus tons (source)! Maybe even bigger than Barosaurus!

Good post about the ruyangosaurus but why do you conclude with these final words: " Let's see T rex fanboys try and beat this! " ?

Quite irrelevant and it isn't the first time you taunt the t-rex. Do you have a metaphysical or existential problem with the t-rex ? Is it a teenager's toothache ? Reply

Could be one of the most massive dinosaur on Earth, but the last remark regarding Tyrannosaurus rex isn't necessary and have nothing to do with sauropods. Reply

No, I have no problem with Tyrannosaurus rex.
The fanboys on the other hand are a HUGE aggravation. Spend some time on any versus topic involving T-rex and you'll see exactly what I mean; they try to pass off the largest T rexes as average, they downplay other dinosaurs, and I even heard one say in a serious scientific debate that Tyrannosaurus rex practically DESERVES its reputation and would win the vast majority of the time against a same sized Giganotosaurus.
Some of the worst fanboys of all, are in Quora and YouTube comments (to them, T rex is 15-16 tons on average and it beats Spinosaurus in deep water due to stronger bite force).

So long story short, T rex is fantastic. But the same can NOT be said for the fanboys.

Anyway......

Here's Xingjiangtitan at 32 meters and probably about 50-60 tons based on relatives

There are complete morons everywhere... Don't try to be as stupid as they are even If I know you can make it.

There's a very, very large unnamed titanosaur from France informally called the French Monster. This is how big it's thought to be based on relatives

Turiasaurus riodevensis. At 30 meters and 50 tonnes, it is Europe's largest dinosaur and one of the largest non-neosauropods, tied with Xinjiangtitan and surpassed only by 75 tonne Mamenchisaurus sinocanadorum. It's pretty bulky too!

Just some food for thought regarding the gigantic (as in REALLY gigantic, 37 meters and 100 plus tonnes) Apatosaurus OMNH 1670 and OMNH 1331: They might have had more than just their size for defense.

So you have these animals over 100 tonnes that also have what are essentially spiky clubs at their disposal. Immense AND well-armed! Reply

Some more stuff on the giant BYU 9024 Barosaurus: https://thesauropodomorphlair.wordpress.com/2019/08/31/did-supergiant-barosaurus-necks-scale-with-positive-allometry/

I think we can be fairly confident in a very large sauropod here. This is in fact about 36 percent more massive than Argentinosaurus! Reply

An other discovery: The titan of Patagonia !

" Patagotitan, the Biggest Dinosaur Ever Found ?

This is Patagotitan's femur next to researcher Pablo Puerta. ?
Patagotitan is a genus of titanosaurian sauropod from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from multiple individuals: Patagotitan mayorum, first announced in 2014 and then validly named in 2017 by José Carballido, Diego Pol and colleagues.
Scientific name: Patagotitan
Rank: Genus
Suborder: †Sauropodomorpha
Higher classification: Lognkosauria
The researchers who described the animal stated:
Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth. "

Just noticed your posts regarding the masses of Notocolossus and Dreadnoughtus, and I think there's some stuff you may like to know.

About Dreadnoughtus: It's actually pretty good-sized; probably larger than the Bates estimate. SVPOW gives a volume of 57 square meters for the skeletal the discoverers put together (here). At a density of 0.85, this gives us a mass of 48.45 tonnes. Still a fairly large animal, by any standard. And seeing as the holotype seems to have been a juvenile, I think the aduit may have been in the territory of the really, really big 70 plus tonne sauropods like Argentinosaurus and Mamenchisaurus.

About Notocolossus: Assuming similar proportions to relatives (lognkosaurian titanosaurs and close relatives), 45-76 tonnes may actually hold up. Scaling from a 30 meter and 50 tonne Futalognkosaurus with a 1.56 meter humerus gives 71.8 tonnes, scaling from Paleo King's 90 plus tonne Argentinosaurus with a ~2.2 meter humerus estimated gives 46 plus tonnes, scaling from a 48.45 tonne Dreadnoughtus with a 1.6 meter humerus gives 64.48 tonnes, and scaling from a 53 tonne Patagotitan with a 1.65 meter humerus gives 64.32 tonnes.

I come just to discover that:

As the biggest one is a dinosaurus, I put this video here. Reply
