However, no matter how much more heavily built it is, in no way is an 8-14 tonne ceratopsian larger than a 69 tonne titanosaur, and it's similar here. Spinosaurus and the giant carcharodontosaurids, despite the fact that they seem to be quite larger than Tyrannosaurus, are less robust than it. Simple as that.

That comparison is not even logic. We do know that those bones are NOT of the same length and not from similarly build animals. So your example is based in simple eye-sight with no information and that is not the case with T. rex and the Carcharodontosaurids. We DO KNOW the length of the long bones of T. rex and Giganotosaurus and those of T. rex are more robust, in fact the entire skeleton is more robust. The comparison with Spinosaurus is similar, but with the entire skeleton and side by side T. rex is far more massive. In this case, Giganotosaurus is a best second place for the heaviest land carnivore dinosaur, Spinosaurus is an aquatic animal based in the evidence.

This massivenes can't be compared with any other carnivore dinosaur:
