Spinosaurus is a large theropod dinosaur with a body length comparable to that of Tyrannosaurus Rex and Southern Megalosaurus. There is currently only one valid species in the genus Spinosaurus, namely the Egyptian Spinosaurus, named by German paleontologist Stromer in 1915. Due to its unique appearance and massive size, Spinosaurus has received no less attention than Tyrannosaurus rex. Unfortunately, the holotype specimen of Spinosaurus was destroyed during World War II. In recent years, new fossil specimens and quantitative studies have shown that Spinosaurus had a highly specialized body structure and was a highly aquatic dinosaur. Spinosaurus is one of the longest carnivorous dinosaurs. Spinosaurus is 10 to 15 meters long and weighs 3 to 10 tons. The World of Animals
