Tyrannosaurus rex

[Spalea]

@DinoFan83 : I just repeat what you told at #163 in this topic:

" I agree with you on that. Tyrannosaurus' skull, torso, and limb bones do seem to be a good bit more chunky and robust relative to their dimensions than those of Giganotosaurus.

Speed should be similar for both. "

You wrote that by seeing two photos showing each one of these predators. Clearly the T-rex's bones show that it was the most powerful predator, and this by far. Giganatosaurus and carcharondotosaurus could be longer but their bones structure were clearly slender. I'm just considering what I see by saying that.

As concerns the spinosaurus, if this animal was a 100% aquatic predator, this question is from now on irrelevant. The spinosaurus's ribs and bones don't need to be as robust as the t-rex's and we saw it was quite the case (see at #110 of this topic). Comparing t-rex and spinosaurus becomes as irrelevant as comparing a t-rex and a marine reptile, even though the spinosaurus is indeed the longest and this by far.

I'm agree with @GuateGojira , T-rex having appeared a long time after Giganatosaurus and Spinosaurus was the terminal form of the big dinosaurs predators, thus the most evolved and performing one, before their brutal extinction. Reply
