"Dinosaur Resurrection": Dinosaur Skeleton

Dinosaur "resurrection" origin
Dinosaur ancient creatures, although extinct for a long time, have successfully replicated simulated dinosaur models, dinosaur specimens, and "living dinosaurs" that will make a sound by using modern science and technology. Zigong City, Sichuan Province is the largest and world-famous research and development base for simulated dinosaurs and simulated animals. Zigong City is a world-famous dinosaur town. The simulated dinosaurs and other artificial animal models produced here are exported to the world.
In the technology research and development of “resurrection” simulation dinosaurs, Zigong industry has invested a large number of scientific research personnel, production and production personnel and research and development funds, combined with archaeology, paleontology, geology and other professionals, since the 1980s began research and production. Simulated dinosaur Zigong City has formed a scaled simulation dinosaur and simulation culture industry chain, and has become one of the pillar industries of Zigong local economy.
In the last century, in 1972, the dinosaur fossils of Dashanpu in Zigong City were first discovered. After studying by experts and scholars in Beijing, Chengdu, Chongqing and Zigong, these specimens only identified 12 genus and 12 species of dinosaur fossils, of which 9 There are 12 new species in the new genus. This is the world famous Dashanpu dinosaur fauna. Since then, Zigong has been studying the production process and production methods of artificial dinosaurs.
A large number of dinosaur fossil sites have been discovered in the Dashanpu dinosaur fossil site, and 18 genus such as dinosaur fish, amphibians, turtles, crocodiles, pterosaurs, and mammalian reptiles have been studied. 21 species. The dinosaur fossil group in Dashanpu, Zigong City has a large collection of fossils, complete categories, burial and preservation.
These complete fossil specimens provide a lot of reference data for simulating the design and use of dinosaurs, measuring fossil skeletons and site data, and deriving different types of dinosaur body characteristics, food characteristics, age, distribution and so on. Referring to these fossil specimens, scientists and technicians produced a model of the simulated dinosaur skeleton.
First, the dinosaur skeleton mold is squared and wrapped with a plastic film to prevent subsequent contamination by clay.

Second, carefully press the piece of clay flat around the skull and wipe the clay surface with a damp sponge to smooth the entire clay contour. The clay will be replaced by synthetic resin, leaving some space for the liquid resin.
Third, insert a pipe in the middle of the clay model, which is used to pour the pouring port for the resin.
Fourth, you need to make a solid shell for the clay mold: the glass fiber is coated with polyester resin, and then laid on the clay, placed for one night, the resin glass fiber will become a hard shell on the clay.
5. After removing the hard shell by about 24 hours, repeat the above steps to get the second identical hard shell. After the two hard shells are facing each other and fixed with screws, the silicone can be poured into the previously reserved pouring port, so that the silica gel can perfectly fill the gap between the real skull and the upper hard shell (also Remember the clay? At this time, the bottom of the skull is clay.) After the silicone is solidified, turn it over and remove the previous clay and repeat the above steps. (When pouring, the silicone is solidified under the skull. ), you can get another layer of skull silicone mold. The gap between the two silicone molds is the skeleton of a dinosaur.
6. After the mold is placed, the plexiglass fiber is attached to the rotary table together with the silicone mold, and the mold is filled with polyurethane, and then the rotary bed is rotated at a set speed, so that the resin is evenly distributed throughout the mold and filled up. The outline of the entire dinosaur skeleton volume.
7. After the resin has hardened, a replica of the dinosaur skeleton can be taken out of the mold.
Eight, after the roughing of the scraping and trimming, it is also necessary to compare the outline of the finely polished replica of the simulated dinosaur skeleton mold.
Nine, then use acrylic to paint a skull replica to achieve the true skull color.
Ten, after fixing the simulated dinosaur skeleton, a replica of the real dinosaur skeleton model has been completed.
