Spinosaurus

Spinosaurus is a species of spinosaurid that lived around 112-95 million years ago. This dinosaur was specially adapted to its environment since it hunted fish unlike the other dinosaurs (Cacharodontosaurus, Bahariasaurus, Deltadromeus and Sarcosuchus). Those dinosaurs hunted the lands limited prey items while Spinosaurus ate the fish that lived in the rivers. Many people suggest that Spinosaurus was a quadruped but if fish was hard to get Spinosaurus would hunt the herbivores in the region.
