means the injury that had occurred on a deceased individual's living tissue which is inflicted by an external force or mechanism regardless of intentional or incidental means. Analysing trauma provides insight in detecting and explaining the lesions on the deceased individual or a respective population. By associating the relationship between trauma and the demographic information derived from the skeleton, the relationship between them facilitates the process of interpreting the socio- cultural variables that inflicted the trauma. Trauma analysis is conducted with the cooperation between forensic pathologists and anthropologists to establish the reason and manner of death. The occurrence of trauma is dissected into three stages which are ante- mortem, peri- mortem and post- mortem trauma. While peri- and post- mortem trauma that occurred simultaneously cannot provide hints for forensic pathologists and anthropologists, post- mortem trauma that occurred after the decomposition stage reveals the distinction between damage inflicted on dried and de- fleshed bones. Age Skeletal age estimation is written in the format of ranges because an individual's chronological age does not necessarily parallel his or her biological age. Individual health, family genetics and environmental stressors affect the skeleton age. Hence, the range format is written in the aim of combining the estimation of the skeleton's chronological age and individual variability. To avoid biased examinations in skeletal age estimation, at least more than one indicators is required. In order to investigate if there is an evidence of growth and development on the skeletons, the evolving pattern and fusion of ossification centers can be used to determine that the skeletons are developed. Thus, this means the skeletons are proven to be entering the stage of maturation. Preservation Skeletons should be carefully managed and protected in order to retain their original state for further research purposes in any circumstances, for instance: educational, archaeological, forensic research. Applying the same case for animal skeletons, there are procedures to follow in the aim of ensuring the skeletal remains are reserved carefully for research purposes in the future. There are various possible sizes of collections that researchers might want to reserve for future investigation. For smaller sizes of bones collections which will be commonly applied to any researchers who retain them for archaeological or zoological educational purposes, it is suggested to organise those bones into categories, for instance: age group, tribal or ethnicity group, or sex. The storage method of such small and sophisticated types of bones
