|Bust of unidentified remains|
If the tissue is decomposed, then the skeleton is turned over to a forensic anthropologist who will study the remains further, by removing the tissue with boiled water or using a colony of dermestid beetles. The bones are allowed to dry and then are examined for signs of trauma. Sex, age, height and race can be determined just by bones. Sex by the pelvis (only if it is an adult) and race by the skull. Previous fractures, signs of diseases, help narrow down the identity. Hip replacements and breast implants yield identities because of the serial numbers.
