For instance, MCF-PVPH-108.202 is 12.2 meters, so yes the exact sizes do vary. A pubic shaft of that (MCF-PVPH-108.145) size would've been indicative of a larger animal, but one within the 12 plus meter size range
2: 10 ton Rex is also impossible - in fact, no theropod would have been over 9 tons save for Spinosaurus. That's beyond the biped weight limit
However, most carcharodontosaurids are fairly poorly known, so we're extrapolating from other dinos. As I said, an 8.5 ton Mapu seems perfectly reasonable to me going by that

Mapusaurus is "larger" than Giganotosaurus, but that is probably just because it was more robust, but even then, the animal seems to be no longer than Giganotosaurus. All the measurements presented and the calculations of Franoys lead to an animals of similar size of Giganotosaurus although heavier, but not close to the large weight of Tyrannosaurus.

Why you think that a 10 ton T. rex is impossible? Many calculations suggest that it could reach that weight. From my point of view I think that a T. rex of 9 tons in the "maximum", but who knows...

Spinosaurus was not ever near to 8 tons, it was long but light in built, so not a challenge for the large Carcharodontosaurids or T. rex. Reply
