There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

2.Bruhathkayosaurus- Bruhathkayosaurus malteyi  might have been between 40–44 m (131–144 ft) in length and “175–220” greater than blue whale tonnes in weight according to some estimates. Its remains found in our country India. This might also be the biggest animal ever. The skeleton lost when floods occurred and assumptions are there that some bones might be fossilized wood. The scientist who put the estimate then said that the estimates are inaccurate afterwards and weight may be somewhat less. The skeleton remains lost during floods. It’s not clear that it’s a real animal, as the few remains we had of it were washed away in a monsoon flood, leaving only some unclear line drawings which could show fragments of sauropod bones or could show petrified wood. At any rate, even if it’s a real animal, it might have been slightly longer than a blue whale but would have been a lot less massive, since a sauropod’s length is mostly long thin neck and tail.
Mickey Mortimer said Bruhathkayosaurus could have been 175–220 tonnes heavy in 2001, but he later changed his opinion and said these numbers are inaccurate but didn’t provide a new mass estimate.

Any animals, other than these that rival blue whale friends? post your findings... :)

Looks like to be some measurements here, which aren´t confirmed at all. Or where can I find confirmation for Amphicoelias fragillimus? Not from that site, which is here as source, I think. Some other figures seems to be more or less uncertain (?). Can you give sources for these dinosaur measurements? it would be interesting to see.

When you put measurements like this here, I think, that sources for anyone to check should be also there. Now you have big figures for dinosaurs and then for instance for blue whale understatement as far as I know. I mean if you put here longest possible estimations of some animal, then fair way to compare is to put same measurements for other animals too. 

Anyway, put some more sources, please. The one you have here seemed to just tell, that Amphicoelias fragillimus size is very questionable. That makes whole posting a bit questionable, sorry to say that.

1 - Bruhathkayosaurus matleyi is lost and there are serious dobts about IF it was a real dinosaur after all.

Check the entire article: http://paleoking.blogspot.com/2012/01/gi...-your.html

Also check this: http://dinogoss.blogspot.com/2011/12/bru...8906512563

2 - About Amphicoelias fragillimus, new studies suggest that was not the "big" beast reported. A new study of Dr Carpenter in 2018 shows that its morphology was not the one of a Diplodocid but just like a rebbachusaurid like Limaysaurus. Even the name changed, is now Maraapunisaurus fragillimus. Check the paper of this study (attached document).

Finally, a comparative image of that document:

So, non of them are real giants, and did not surpassed Argentinosaurus and other giant sauropods.

Other two posts about how big was Maraapunisaurus fragillimus, older than the new study of Dr Carpenter, by the way:
https://www.deviantart.com/palaeozoologist/journal/Amphicoelias-fragillimus-smaller-than-you-think-424759499  - from January 4 2014.
https://www.deviantart.com/palaeozoologist/journal/Was-Amphicoelias-a-rebbachisaur-440611550 - from March 15 2014.

It seems that Maraapunisaurus fragillimus was about 30 meters long and about 80 tonnes.

About Barosaurus and Mamenchisaurus, the estimations taht I have saw are still not quite clear and are highly speculative, but will be interesting to see those results.

3 - Finally, about Shonisaurus sikanniensis, previously clasified as Shastasaurus, was probably about 21 meters long, still a giant but not near the blue whale.

Check this link:http://www.tyrrellmuseum.com/exhibits/triassic_giant.htm

There is a new specimen reported in 2018 of a new Ichthyosaurus estimated at up to 26 meters long.


More images of this giant:

A real monster and was amazingly found "in situ", which is incredible.


However the report itself had assuptions, for example: "We compared our jawbone to that of Shonisaurus sikanniensis, the largest ichthyosaur previously known, with an estimated length of up to 21 meters," Massare told Newsweek. "Our bone was about 25 percent deeper. The estimate assumes that the two animals had a similar shape for this bone, as neither specimen preserves the entire bone."

If there were differences between the new species and the Shonisaurus sikanniensis, the estimation will be invalid, but even then the animal was huge.

So, for the moment, it seems that the largest sauropods are still about 30 or maybe up to 40 meters long but still don't surpass the 90 tons. Whales are still on the top and the blue whale is still the biggest animal ever, or not???

Biggest animals (whales) known to mankind. Then elephants. Fake dinosaurs cannot be considered as biggest animals.

We can't talk about the largest animals ever without mention the true king of beast (by size and weight), the blue whale!

Why you say "fake"? What do you mean with that?

Some time in the past, I watched a documentary on dinosaurs which told of water displacement to receive very near-accurate weights of animals. According to this documentary, if a person can create an accurate model of the animal made perfectly to scale, he can then use water displacement to acquire its weight. You have a container with a precise amount of water in it right up to the rim. then, when you submerge the model, the displaced water can be weighed. Of course, this requires a mathematician.
