Giganotosaurus and Tyrannosaurus: which is the biggest?

That's why I think UCMP is something possibly similar to Sue, not necessarily larger, nor smaller.

Scotty is possibly bigger than Sue.

Scotty was certainly a big one(at least comparable to Sue)...

From Campione et al. 2014,

RSM P2523.8 is Scotty.

Compared with other large theropods body mass data :

You understand why I give a slight edge to Tyrannosaurus, even if it's more a matter of specimens compared with specimens rather than species with species.

Note that MUCPv-95 has not been used in that least, presumably because it's a very fragmentary specimen, so less reliable.

Peter Larson told me in an email that Stan was quite large actually(at over 12 meters long), while Wikipedia says it was much smaller(10.9 meters). Stan seems hard to read(if that makes sense). The holotype was 11.9 meters long, Scotty is 12 meters long, MOR 008 was 12 meters(according to Carnosaur), and AMNH 5027/Wankel Rex are both about 11.6 meters long.

After looking through the specimen list for T.rex on the Theropod Database, I've concluded that they give ridiculously strange sizes. For example...

Stan is listed at 12.4 meters long and 3.7 tons

Sue is listed at 12.8 meters long and 5.654 tons

AMNH 5027 is listed at 12.4 meters long and 5.7 tons

MOR 008 is listed at 13.8 meters long and no weight is given

Here's the link...

Yeah, uh, I don't get it.

Yeah, that makes no sense.

Actually, ghe only point against MUPCv-95 being larger is a proportionally larger jaw. T.rex's large specimens are even less reliable, for the motivations I've already stated. 

Kom, most of the paleontologist - like Holtz - usually take in account MUPCv-95, while ignoring larger-than-Sue specimens. That slight edge you're talking about is the size of largest Tyrannosaurus, wich are 2-3; most of the specimens aren't bigger at all, so, if only 2-3 specimens of over 30 specimens are larger, the size must be about the same. 

Gigadino, yes MUCPv-95, being more documented, is naturally taken into account more than the fragmentary, not yet pubished Tyrannosaurus specimens.

But that's not always the case : http://carnivoraforum.com/single/?p=8704127&t=9327489

You see that Scotty here is stated bigger than Sue and CM9380 is bigger than Giga's holotype. 

This clearly suggests a slight edge for Tyrannosaurus.

How do you know that only 2-3 specimens on 30 specimens are larger ? Have you all the data about the 30 specimens individually ?

It is wrong to ignore larger the due specimens just because they are not trusted. P.s carnosaur, kom, and giga Go check the largest theropod thread.

Another large T.rex specimen is one nicknamed King Kong. It's an estimated 12 meters in length.

All the 30 specimens are all estimated to be between 10 (B-rex) and 12 (Stan) meters long. Only large specimens exceeded 12 m.

It's the fourth (fifth?) time that you repeat that Scotty is larger; I've understood, but you are giving a slighty edge based on a few specimens, wich are the biggest. Based on know specimens, both the taxa reached a equal size. We can say that T.rex has the largest confirmed size, even by a slighty margin, but only a few specimens reached that size - most of them are actually as big or smaller.

Gigadino, yes, and how much are estimated to weigh each of these individuals ?

http://carnivoraforum.com/single/?p=8704127&t=9327489

CM9380 is heavier than Giga's holotype.

Note that MUCPv-95 is not listed, presumably because it's a small fragmentary based specimen.

Agreed with the remaining part, that's why I don't say Tyrannosaurus is the biggest, I give it a slight edge given the available data. But several specimens appear heavier than the larger Giga specimen and even more are heaver than Giga's holotype.

MUPCv-ch1 was likely outsized by MUPCv-95, wich is 7-8 t (as it's 2,2-6,5 % larger), so it ouweighted some T.rex specimens.

No i'm not on carnivora.

Fair enough for your last post Gigadino.

I agree with all informations you typed, but did you know that actually sue is slightly taller and bigger than giganotosaurus holotype which is just a little bit longer?
