1. Repair with glue: If part of the bone model is broken cleanly and completely, try to repair it with suitable glue. Pay attention to choose the glue with suitable material and apply it on the fracture surface, then align the two fracture parts and press until the glue is dry. Ensure that the repaired connection is firm and avoid breakage.
2. Seek professional repair: If the bone model fracture is complicated or needs fine repair, it is recommended to seek the help of a professional repair master. Professional restorers have rich experience and suitable tools, which can repair the model more accurately and keep the original appearance of the model as much as possible. You can consult local museums, dinosaur exhibition centers or art restoration agencies to find out whether they provide related restoration services. The model, with the help of physical or virtual representation through subjective consciousness, constitutes an object that objectively expounds the morphological structure and expresses the purpose (object is not equal to object, not limited to entity and virtual, plane and three-dimensional).
