Spinosaurus, meaning "lizard with thorns", is the star of Spinosaurus family and the largest carnivorous dinosaur in the world. Its body length has reached 18 meters, and even the sail on its back is as high as 2 meters, which is very spectacular. As the largest carnivorous dinosaur, it is reasonable to say that it can rely on its huge body to defeat all its opponents.
Spinosaurus has obvious long spines on its back, which are formed by extending the nerve spines of the spine, and the length can reach 1.69 meters. It is inferred that there are skin connections between the long spines, forming a huge sail. However, some scientists believe that these long spines are covered by muscles, forming a hump or back.

Historical evolution of the discovery of Spinosaurus;
1, 19 10, a nobleman named Ernst Stemmer from Bavaria entered the Sahara desert in the Egyptian hinterland. The team led by Stemmer met with many difficulties. Under such difficult conditions, Stemmer discovered 45 kinds of fossils of dinosaurs, crocodiles, turtles and fish.
Among many fossils, one group is numbered IPHG? 19 12VIII？ 19 fossils are particularly striking. This group of fossils includes 75 cm long incomplete odontoid bone, 19 teeth, 2 incomplete cervical vertebrae, 7 vertebrae (19 to 20 cm), dorsal rib, abdominal rib and 8 coccygeal vertebrae, in which the length of dorsal nerve spine reaches 1.69 m. ..
2. 19 15 years, Stemo officially named the giant carnivorous dinosaur he discovered Spinosaurus, which means "lizard with long spines", derived from its long dorsal nerve spines. The model species of Spinosaurus was named Spinosaurus aegypti, representing Egypt where fossils were found.
3.1On April 27th, 944, nearly a thousand American heavy bombers took off from Britain, aiming at Munich. In the fierce bombing, the museum was in ruins, and a large number of paleontological fossils in the museum, including spinosaurus fossils, were blown to ashes.
