Scott Hartman is known for his dinosaur skeletals. I found two that are quite interesting. They both deal with Giganotosaurus and Tyrannosaurus...

 

 

 

In both instances, Giganotosaurus is seen to be outweighed by T.rex(quite substantially in fact). 

 

I just figured I'd share these with you all. Personally, I agree with Hartman that T.rex outweighed Giganotosauurs.

Well I disagree, I say they were even in weight. Though thanks for posting this.

REX FAN 684 - How very neat! I've always been on the fence with regards to the weight issue. However, I'm of the opinion that Tyrannosaurus likely outweighed Giganotosaurus due to muscle mass. Out of curiosity, how much taller was Giganotosaurus than Tyrannosaurus? The disparity does not seem to be that drastic. These images are extremely interesting to observe! Thank you so much for sharing them! :)

Nice post, though I still think Giganotosaurus is larger. Dinosaurs like Sue and Celeste were on the larger size of a T-Rex, an average Giganotosaurus was about the size of Sue. In my opinion Sue is not a good specimen to use as an estimate for the size of an AVERAGE T-Rex. Also Celeste left very little bones behind so we can't know its true size, Scott even puts a ? after it.

@ SOMETHING REAL, For the most part, Tyrannosaurus. Also depends on what you take for height. At hip height, T. rex probably takes it with a VERY small difference. Like about .15 to .7 of a meter. At head height, easily Tyrannosaurus. Tyrannosaurus' head could reach (on maximum sized specimens) 6- 6.5 meters in the air. Tyrannosaurus was probably all around bigger at large to maximum sizes.

PRIMAL KING - Thank you ever so much for this information! It certainly helps to fill in a few gaps in the understanding I possessed concerning these animals! Very compelling! :)

the 'average' tyrannosaurus is a lot easier to discern then in giganotosaurus sheerly because we have many more individuals (40+ vs 2) now, i did the math on this waaaayyy long ago. but, here goes; the smallest rex individual “black beauty” measured ~10.6 meters. “Bucky” is a close second. "sue" is the largest confirmed described specimen at 12.3 meters. from this, we can safely ascert T.rex had an average length greater then 10.5 meters. saving y'all from the boring math & listing of mature T.rex specimens, i arrived at an 'average' of 11.3-11.8 m (taking various measurements from multiple sources. weight was trickier, but i got 6.3 - 7.2 tons for an average rex. again, taking multiple sources into consideration. giga it's harder to claim an average. the holotype was ~12.4 meters & the paratype has a lower jaw fragment from an animal 6.5% larger then the holotype. this would put it at a length of ~13 meters. weight estimates for this species vary greatly, but i've estimated the giga holotype at 6.8 tons and the paratype at 7.5 tons. based on this, giga & rex were roughly the same size on average, while rex was larger based on the largest specimens we have(8.3 vs 7.5). my methods are a bit conservative but overall parellel to Hartman's. I'd also like to stress the above results only show the greater population sample of T. rex and i have severe doubts G. carlinii's paratype was the largest we will find of the specie.

Wouldn't be surprised if Rex weighed more than Giga.

@SOMETHING REAL.

Sure!!!!  Just let me know of you have any more questions!

@Carnosaur,

Not sure if we'll find another larger specimen, but the holotype you're baskng off is a little too large. :)

PRIMAL KING - Certainly! Thank you ever so much! :)

CARNOSAUR - Wow! That was a very insightful collection of data you presented! Very neat! :)

The difference is very small. 200 kg are nothing in two big animals like T.rex and Giganotosaurus, and intraspecific variations make that difference meaningless. Plus, if we're comparing the largest, why not comparing the smallest? Now, wich is bigger, B.rex or MUCPv-ch1? We cannot compare those two animals, we've got just 2 Gig specimens, while we have 30 + T.rex specimens. From what we have, they both reached the same size, or ~8 t.

MemberCompsognathusDec-17-2014 10:44 AM

@PK, ermm...no. Do you have a source for that claim?

Mucvp-ch1 has always been estimated at ~12.4 meters.

I just noticed S.hartman estimateos it at 12.4 meters too....neat.

Ok, I'd like to add some things...

First off a consideration that hasn't been made is the fact that the avergae Tyrannosaurus specimens are about the same size as the smallest giga, about 6.5-7 tons and 11.5 meteres to  the average Tyrannosaur, the smallest giga we have messures about 12.4 meteres and around 6.8 tons.

 

Also the height issue, erm no T-rex is not much if any taller then giga... At hip or head.

Size

Also Giga has taller vertibra then T. rex, which means more room for muscle attachments, which would gove giga some extra weight, also I'm pretty sure (not 100% certen so take this with a grain of salt) that Giga has a deeper rib cage which would most likly give it a weight advantage.
