The morphological characteristics of the dinosaur model, the skeleton of the dinosaur has some derivative adaptations, which can distinguish them from the original main dragon ancestors. In later dinosaurs, these characteristics have undergone more evolutionary changes.

Most dinosaurs have some common characteristics, but because they appear in other main dragons, or do not exist in early dinosaurs, they are not listed as common dinosaur derivatives. Dinosaurs have an upright gait, similar to most modern mammals, while most other reptiles have a gait that extends to the sides. The dinosaur’s hip socket faces both sides, and the fourth trochanter of the femur faces inward. The two fit together. The femoral head is perpendicular to the femoral shaft, producing an upright gait.

Dinosaurs are very large overall. Taking dinosaurs as a standard, the sauropods are among the giants. In the long dinosaur era, even small sauropods were larger than other animals in their habitat, and sauropods were several orders of magnitude larger than any animal that appeared on the surface.
