How did spinosaurus live on earth millions years ago?

Spinosaurus lived during the Late Cretaceous period, around 100 to 93 million years ago, in what is now North Africa. It was a large, semi-aquatic dinosaur, adapted to both terrestrial and aquatic environments, featuring a long, crocodile-like snout and conical teeth suited for catching fish. Its distinctive sail-like structure on its back may have been used for thermoregulation or display. Spinosaurus likely inhabited river systems and coastal areas, using its adaptations to hunt in water and on land.
