That, and it helped that the T.Rex featured in JPIII was believed to be a sub-adult. Since Rexy was capable of slamming the I.Rex around like a chew toy after she got to her feet again, it's presumed that a full-grown T.Rex would be able to beat a Spinosaur, especially with its bite force alone.

Thus, I think the I.Rex would easily be able to best a Spinosaur. Besides having the intelligence of a raptor and strength of a T.Rex, I'm sure she also had a similar bite force to the T.Rex as well.
