Cracking, crumbling, non-pleasant smell and changing bone color during and after bone preservation are the most common issues in the former skeleton models' preparation.This qualitative-experimental project presents a new technique by mixing between a number of the old techniques of preservation of the skeleton models via the below four main steps: First, boiling the bones with tap water and degreasing with a detergent. Then, drying naturally under sunlight. Afterward, boiling with 3% hydrogen peroxide. Finally, re-attaching and installation of the final skeleton model on a wooden plate.The vertebrae was articulated with each other in their main anatomical positions. The ribs were fixed with the thoracic vertebrae. The mandible was attached to the skull, and the skull was installed into the vertebral column. The fore-and hind-limbs were assembled; the scapula was attached with the ribs and the femur with the pelvic bone at the acetabulum. Finally, the carpal, tarsus, patella, and sesamoid bones were assembled and fixed in their main anatomical positions. The final installed skeleton formed with desirable white color, with no foul smell, no crack and crumble and highly tolerable to cold and hot temperature.The present study Proposed that prepared sheep skeleton model can be used to promote the veterinary students' comprehension for the anatomy courses since the method has been used in this study resulted in a high-quality skeleton model in its color, texture and tolerability with no irritant foul smell.
