Spinosaurus was a colossal theropod dinosaur that lived during the Cretaceous period, approximately 112 to 93 million years ago. It is one of the largest carnivorous dinosaurs known, reaching lengths of up to 50 feet and weighing as much as 20 tons. Spinosaurus is renowned for its distinctive sail-like structure, formed by elongated neural spines on its back, which could have been used for display, thermoregulation, or storage of fat. Another unique feature of Spinosaurus was its crocodile-like skull, equipped with conical teeth well-suited for catching fish, indicating a semi-aquatic lifestyle. Its elongated, muscular forelimbs, equipped with large claws, suggest it was adept at catching and handling prey. Fossils of Spinosaurus have been found in North Africa, particularly in Egypt and Morocco, painting a picture of a versatile and formidable predator that thrived in both terrestrial and aquatic environments.
