Spinosaurus

Spinosaurus was one of the largest carnivorous dinosaurs, living during the Late Cretaceous period about 99–93 million years ago. It is famous for its distinctive sail-like structure on its back, formed by elongated neural spines, which may have been used for display, thermoregulation, or storing fat. Spinosaurus could reach lengths of up to 50–59 feet (15–18 meters), making it even longer than Tyrannosaurus rex.

Unlike most theropods, Spinosaurus was semi-aquatic, adapted for life in rivers and swamps. It had a long, crocodile-like snout filled with conical teeth, perfect for catching fish. Fossils have been found in North Africa, particularly in Egypt and Morocco.
