 Given that the microscopic pattern of nonhuman bones is plexiform or fibrolamellar if the primary osteon has the linear arrangement of rows or bands, analysing the microscopic anatomy of large mammalian bone fragments enables the forensic anthropologists to distinguish large mammals.This does not mean that microscopic methods can be applied in identifying human bones.Protein radioimmunoassay is a biomolecular method that identifies human bones and eliminates any nonhuman bones.
