Spinosaurus lived during the Late Cretaceous Period in North Africa, inhabiting environments such as tidal flats, mangrove forests, and riverbeds. These regions were characterized by a mix of aquatic and terrestrial landscapes, providing opportunities for both water-based and land-based activities. Periodic droughts during the hottest times of the year often dried up lakes and rivers, potentially forcing Spinosaurus to adapt by hunting or scavenging on land. 

While its exact lifestyle remains debated, some paleontologists suggest it was primarily aquatic, while others propose it was a versatile predator capable of thriving on both land and in water.
