Interesting Skeletals by Scott Hartman

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! :)

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.

@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.

I've seen these before but they are still cool

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.

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.

Thanks for sharing this with us! :)
