So I decided to pull information from a number of sites, books, and documentaries to try and determine how T.rex weight was distributed. Here's what I came up with...

 

Body/Torso-

 

T.rex had an immense body. The ribcage was huge and could house a lot of organs and muscle. The bones themselves were also quite heavy. Overall, the torso probably weighed a good 3-4 tons on it's own.

 

Head/Neck-

 

The head and T.rex were enormous. The skull alone weighs a good 600 pounds. Factor in the muscle that would have been there when the animal was alive, the head region would weigh well over 1,000 pounds.

 

Legs-

 

The legs of T.rex were actually the longest proportianally of all the giant theropods. The bones were huge, as were the muscles. Together, both legs weighed some 3-4 tons!

 

Tail-

 

The tail of T.rex was huge(some 15-20 ft long) and needed to counter it's huge head. With it's large bones and immense muscles, the tail alone could weigh some 1,000 to 2,000 pounds!

 

So, all in all, that adds up to around 7-9.5 tons of weight. That's right in line with many modern estimates on T.rex's overall weight. Just figured I'd share that with you all :)

REX FAN 684 - That was very fascinating! The overall amount of information you provided really helped me put the animal's physiology into persepective without being overly complex. Excellent work! Thank you very much for sharing this with us! :)

How did you estimate that weight? 

I did some math, and I came up at 8 t, by scaling from Tarbosaurus. You must consider that Tarbosaurus is a bit skinnier than T.rex, so I'd add 200-300 kg, but still between 8 and 8.5 t.

What do you mean? I just added up the weights of different areas of a T.rex and got the overall weight. And, technically, your 8-8.5 ton estimate falls in the 7-9.5 ton estimate I came up with.

I meant how did you estimate the weight of the various parts of the body?

I didn't estimate anything myself. I just remember reading/hearing these weights thrown around on different sites, in books, and a documentary or two here and there. I just added them all up and it made sense to me.
