Here is some info on the T.Rex/Spinosaurus situation. Jack Horner a well known paleontologist was a paleontology consultant to make things fairly accurate for the third Jurassic Park film. Horner is well known for his (somewhat ridiculous) theory of Tyrannosaurus being a major scavenger instead of an animal that primarily hunts for it's food. He is known for his dislike of tyrannosaurus and for the films he was always urging the crew to show the Rex as more of a scavenger. So when Spinosaurus got the lead role as antagonist and the T.Rex vs Spino was given and thus that caused a lot discontent and resentment in the dinosaur fandom. What really made people upset was that Horner supported Spinosaurus being an uber predator and tried to make T.Rex a scavenger. Now on the VS. situation while Spinosaurus had a size advantage recent reports show Tyrannosaurus could get bigger than previously thought. So if the two were to live in the same environment they'd most likely avoid eachother and I highly doubt a Spinosaurus could kill a Tyrannosaurus as easily it did in the film. Both have the tools to seriously woulnd or kill eachother.
