1. First draw a lying M-shape to form the mouth of Spinosaurus.
2. Then, draw the head of Spinosaurus with two curves connecting the M-shape, and draw the eyes on the head. Draw teeth in your mouth.
3. Hand-painted Spinosaurus under your head.
4. Draw the back and abdomen of Spinosaurus with three curves of different lengths.
5. Draw the foot of Spinosaurus at the end of abdomen.
6. Draw the tail of Spinosaurus with two curves.
7. Draw an inverted U-shape on the back of Spinosaurus with compact wavy lines to form a long thorn on the back of Spinosaurus.
8. Draw some lines of different lengths on the long spine to highlight the details of the back.
Knowledge expansion
Tyrannosaurus rex belongs to Tyrannosaurus rex, the only species under it. It was described and named in 1905 by Henry Osborne, an American paleontologist and academician of American College of Arts and Sciences. If we refer to other translation formats of dinosaur names, it would be more appropriate to translate their names into Tyrannosaurus rex. Adult Tyrannosaurus rex is about 12 meters long and weighs about 7 tons. It is one of the largest land predators in the history of the earth.
Tyrannosaurus Rex is a famous dinosaur with a huge collection of specimens, of which dozens of specimens have reached a very high degree of integrity, which makes paleontologists study Tyrannosaurus Rex not only in the classical morphological description, but also in its individual development, biomechanics, population biology and so on.
For example, the biomechanical study of Tyrannosaurus Rex's skull shows that it has the bite force to crush bones, the three-dimensional reconstruction of its skull shows that Tyrannosaurus Rex has excellent vision and smell, and the study of Tyrannosaurus Rex's individual development sequence shows that Tyrannosaurus Rex grows very fast. Many research methods that cannot be implemented in other dinosaur species or other paleontology can be tried with Tyrannosaurus Rex.
In terms of scientific research, Tyrannosaurus Rex has its own review papers in the top international academic journal Science, and various related studies will also frequently appear in top academic journals such as Nature and Science.
Although the size of Tyrannosaurus Rex has been challenged by large Allosaurus and Spinosaurus, it is still a veritable king of dinosaurs in terms of comprehensive research depth and cultural influence.
Early studies showed that Tyrannosaurus rex and Allosaurus were closely related. At present, the mainstream view is that the whole Tyrannosaurus belongs to osteophyte and is a relatively progressive branch of Stegosaurus. Compared with Allosaurus, Tyrannosaurus rex was more closely related to birds.
Within Tyrannosaurus rex, Tyrannosaurus rex belongs to Tyrannosaurus rex subfamily, which is closely related to Tyrannosaurus mongolicus and Tyrannosaurus rex in Zhucheng, China. There used to be some views that Tyrannosaurus Warriors was another species under Tyrannosaurus Rex, but the more mainstream view was that Tyrannosaurus Rex was a genus independent of Tyrannosaurus Rex.
