In the production of skull specimens, found a case of cranial cavity with free bone chips .In 1985 Tongliao City, Inner Mongolia will cemetery before the 60s designated as the national cemetery.Part of the tomb no owner claims, after we collected, the specimen is the unearthed unearthed From the size of the pubic corner and the degree of absorption of alveolar bone judgment, the bone is a male old, full of skull, no traces of trauma, the gap tight, hard, feel heavier than the skull. In doing specimens, shaking the skull can hear the sound of the brain cavity which has a hard object impacting the cranial wall.From the occipital foramen to the intracranial observation, there is a can move freely flaky hard objects, the outer diameter than the occipital hole Big, can not be completely removed. So they will put his finger into the hard stamping, carefully pour out the collection, the color yellow or gray bone fragments will spread out, and try to reset according to their original cross-section to show the overall in the cranial cavity The original view of the restored bone fragments in the overall view of the dome-like shape, an area of about 12 × 10cm ~ (2). Peripheral thin irregular local mild curly middle thick. Convex overall view of the surface smooth, local was hilly Ups and downs, resembles the pouring of molten iron condensate
