Dinosaur skeleton repair work. The primary task of repair work is to sculpt unexposed fossils from the surrounding rock without damage, and stick the broken fossils to complete, so as to restore the true face of the dinosaur skeleton and facilitate the research by experts. Personnel engaged in repair work should have a certain knowledge of dinosaur bones. At least they can identify which part of the dinosaur’s body the exposed bones are, such as the skull, spine, and limb bones.
(1) Mechanical repair method. Although repair tools have improved considerably in recent years, the most commonly used are hammers and chisels. When using these tools, be sure to put the fossils in the sand table, and some need to use sand pillows of different sizes in different places to maintain stability. When repairing, a hammer and a chisel must be carried out purposefully. Be very careful not to damage the fossils. If the surrounding rock is very hard, you can use an electric engraving machine or a dental doctor’s straight or high-speed molar for drilling or filling. A pneumatic engraving machine or a pen-type pneumatic drill can also be used as required.
