A mathematical analysis on Giganotosaurus mass.
First of all, the results:


Conclussions , methodology, and anatomical references: 
For those who don't know which method was used, I recommend reading the previous journal entry, about a mathematical anaylsis on Spinosaurus mass , another legendary carnivorous dinosaur; and this excelent post by SVPOW. https://svpow.com/2011/01/20/tutorial-11-graphic-double-integration-or-weighing-dinosaurs-on-the-cheap/
Overall the method intends to construct a simplified 3D model of the animal by building eliptical cross sections and adding them up, given two views of each of it's body sections. The analysis is performed by a matlab mathematical script with pixel accuracy.
The skeletal used is my own bet on the animal. Sadly, and despite more than 22 years having passed since the animal was first (and very briefly) described, most of it's material is not described in detail, specially the axia

Tyrannosaurus rex size.
Introduction:
As Chritopher Brochu once noted in his osteological study on Tyrannosaurus: "Nothing evokes prehistory more than Tyrannosaurus rex. Nearly any five-year-old in the industrialized world knows what it is, and to many, Tyrannosaurus is the quintessential predatory dinosaur-as Paul (1988:344) stated, "this is the theropod." It is the only nonavian dinosaur (and one of the few organisms) popularly known by the specific rather than generic name-"T. rex" is as common in the popular media as "Tyrannosaurus."
As well as:

“Tyrannosaurids are no more relevant to phylogenetics or comparative biology than any other group of organisms, but they are extremely popular. When we do science with Tyrannosaurus, we do it with a broader audience than if it were done with almost any other animal.”

Along with the biggest fame, come the greatest hyperboles, and the highest numbers of fanatics, as well as the most intense of them. However so do the most har

A mathematical analysis on Tyrannotitan mass.
The results first:


Here you have the previous calculations made with the method used; graphical double integration, a type of vollumetric estimation.


The method consists in constructing a simplified 3D model of the animal mathematically, by building eliptical cross sections and adding them up, given two views of each of it's body sections. The analysis is performed by a matlab mathematical script with pixel accuracy. More information about the method itselft here:

Some discussing about Tyrannotitan size and overall proportions:

The skeletal used was made by me from scratch, using mainly the information (figures, measurements, and descriptions) in Novas (2005) and Canale , Novas (2014); using Sereno 1996, Coria 1995, and Currie and Carpenter 2000 to fil

A mathematical analysis on Spinosaurus mass.
Description of the method:
Graphical double integration performed by Matblab program.
We calculated the mass of the North african theropod dinosaur Spinosaurus aegyptiacus, using a graphical double integration method. We believe GDI is in itself, and without a doubt, one of the best methods to calculatte the mass of extint organisms, and the best that can be used using a multi views silhouette from the animal. The method averages a big amount of eliptical sections to aproximate the volume of a complex 3D object. The more eliptical sections, the more accurate the result will be, when a number of slices made is surpassed the result will be almost real life-like.
This matlab program utilizes digital image processing technology to analize two silhouettes from different views. It counts the number of non white pixels in every pixel-wide column from the image, and produces one slice per pixel. In response, the program is extremely sensitive to irregularities in the silho

Mucpv 95 vs FMNH PR2081 'Sue'

not much more to say really.

UCMP 118742 v.s 'Sue'
a size comparison between UCMP 118742 and 'Sue'

CM 9380 has a 69.5 cm maxilla compared to the 81 cm maxilla of UCMP 118742 it would be approximately 13.85 meters long and 11.9 tonnes if it had the same proportions as CM 9380. 

UCMP 118742`s size here is derived from CM 9380, this is not factual only a possibility.

Skeletal`s are made by franoys.deviantart.com/

(This is why scaling is unreliable)

update 5/26/2017 down sized UCMP 118742 from 14.9 meters and 15.18 tonnes to a much more reasonable 13.85 meters long and 11.9 tonnes. (its only 16 years old after all)

Word of advice to you, kirkseven, I'd ignore this guy. If you really want Chagas out of your hair then block him. I'm tired of him spreading slander is all.

he was never a problem to me so far.

I might block him, but only if he does something block-worthy.

Typical of him. He just say what he thinks but does not justufy it. Like "X is true and that is it". He even made it clear that he is that kind of person that says "YOU should block this guy because I do not like him".

Now I see that Sekley is also brainwashing you. He said I spammed TyrantTR, when in fact I just pointed things that mey be innacuracies on his model. Having in mind what Sekley said, correcting paleoart mistakes is spam.

Also notice that I was being respectful towards Jake.
