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. For a long time, paleontologists' understanding of Spinosaurus has only been limited to photos of holotype specimens and a few fossil fragments. With the gradual increase of fossil evidence in recent years, the true image of Spinosaurus has emerged.
