Spinosaurus fossils are dated to between 112 and 97 million years ago. They probably died out around 97 million years ago.
A spinosaurus died out because all the food it normally ate died out and the rivers dried out.
While its not really known, it is a widely accepted theory that since Spinosaurus relied so much on the rivers and the shallow seas, as the environment around it changed, it got drier and slowly these environments of water dried out, thus completely devastating its main food source.

There is no evidence of cannibalism in Spinosaurus. However, many reptiles are cannibalistic on occasion, and there is a chance that Spinosaurus was, too. If it were, however, the only cases of cannibalism would be when large Spinosaurus killed and ate the young offspring of other Spinosaurus.
Missouri is a state - it is not a living thing so it cannot go extinct.
It is impossible to know for sure since both animals are extinct and they both lived during different times and in different places. T-Rex's bite force was much stronger, but a good bite from Spinosaurus could also kill. Spinosaurus was larger and had powerful forearms, but T-rex was more muscular and heavily built. A lot of people have their opinions, but the true answer is the winner is whichever dinosaur attacks first.
