Spinosaurus were mostly fish eaters, although they would occasionally scavenge on large dinosaurs or hunt small dinosaurs. Their lifespan is unknown, but paleontologists believe that most large theropods, or meat eating dinosaurs, only lived around 30 years. Their fossils have been found dating between 112 and 97 million years old, so they probably died out around 97 million years ago.
