Spinosaurus may have been bigger than Tyrannosaur Rex, but Tyrannosaurus may have been able to outrun Spinosaurus due to it's smaller size. Although Spinosaurus's jaws would had been able to pin a predator down, the biting force of Tyrannosaurus Rex should be not underestimate due to its ability to crush bone. Tyrannosaurus Rex's intelligent would be enough to outwit Spinosaurus, and defeat its opponent. This is the reason why my vote goes to Tyrannosaurus Rex.
