UnDisciplined: Dense bones allowed the Spinosaurus to hunt under water

Large two legged carnivorous dinosaurs – such as the Spinosaurus – have been presumed to be land based species with occasional waiting habits for a long time. But the bone density of newly discovered fossil evidence suggests that they may have been subaqueous foragers, which means they pursued prey underwater. This has big implications for what life was really like for theropod predators in the Early Cretaceous.
