What I found

I was looking through the Internet and found a skeletal comparison of T. rex and Giganotosaurus. [img]http://www.mrugala.net/Nature/Animaux/Dinosaures/Giganotosaurus%20&%20Tyrannosaurus%20(02).jpg[/img] I found it interesting that the skeletons have similar bone sizes, (I just learned about this in science class) the ones of Giganotosaurus are slightly smaller, but barely. Especially the legs. They are about the same width, so they probably carried the same weight. There is no way that T. rex could be 8-9 tons at 42 feet long while Giganotosaurus only pushes 8 tons. At least based on this. I will find more pictures like this, so expect a revision.
