Final answer:
To determine the age at death from skeletal remains, traditional paleodemographic age-estimation methods and transition analysis may be used, with transition analysis providing a more accurate estimation for older adults.
Step-by-step explanation:
Two methods to determine the age at death of an individual using skeletal remains are traditional paleodemographic age-estimation methods and transition analysis. Traditional methods rely on morphological changes in the pelvis and skull to categorize remains into age stages; however, they tend to underestimate older adult ages. Transition analysis overcomes this by using Bayes's theorem and data from known-age reference samples to more accurately estimate age, even distinguishing between older adults with different morbidity and mortality profiles.
