According to manufacturing process, simulation dinosaurs can be divided into two kinds:

The first kind is using of steel skeleton as a dinosaur stent, making three-dimensional processing of muscle with sponge or foam and shaping the cortex with silica gel. If you need more vivid, such as: swinging head, opening mouth, shaking front paws, swinging tail and making a horrible voice, you should install motor parts inside to control program and supply power.

The second kind of simulation dinosaurs is sculpture dinosaur, which is mainly made of fiberglass (FRP). It can be used for ornamental and stay outdoor for a long time. The manufacturing process also is made up of steel as skeleton, then skin by fiberglass, cement sculpture. The dinosaurs can be made different postures, look vivid, but can’t do mechanical motion.
