Estimation of age-at-death is more difficult than the attribution of sex from skeletal material as there are only two options for sex, whilst ageing is a continuous process. This means that it is virtually impossible to age individuals, especially adults, with a great deal of precision. A further problem for the estimation of age-at-death is that an individual’s biological age may not reflect their chronological or actual age. This is because the relationship between the degree of skeletal development or degeneration and the actual age of an individual is not linear.1
