Well it's not just that. In comparison to predators of a similar size, Spinosaurus was feather weight. It's bones and musculature weren't as dense as say Charcheirodontosaurus or Giganotosaurus, which was beneficial, having dense bone and muscle would've made it much harder for an amphibious animal like spinosaurus to swim. In muck and mud of the swamp, it kept spinosaur mobile. T Rex on the other hand, it was a living war machine. It's bone was thick, it's muscle was meety as a fuck. It was built to hunt prey animals that fought back, shit like Torosaurus, Triceratops, and maybe even an Ankylosaur. It could take a beating and it could deal eat armor piercing bites.

In a direct duel like what happened in JP3, Spinosaur should've been overwhelmed by the Rex's sheer tankiness.
