How did Spinosaurus hunt?
Spinosaurus likely hunted by using its jaws to capture prey. It possessed adaptations for capturing fish, including a long narrow skull, and straight, conical teeth. However, teeth classified as coming from spinosaurids (that is, a member of the dinosaur family Spinosauridae) have been found embedded in pterosaur bones, Spinosaurus was also likely to have hunted terrestrial prey.
