الملخص	Osteological age and sex estimation is the foundational bioarchaeological procedure for building a biological profile from human skeletal remains: estimating how old an individual was at death and determining their biological sex. The skeleton changes in patterned ways across life — teeth form and erupt, growth plates fuse, and joint surfaces and bone microstructure gradually degenerate — and these changes are scored against reference standards to bracket age, while sexually dimorphic features of the pelvis and skull indicate sex. The standardized recording protocols compiled by Jane Buikstra and Douglas Ubelaker provide the discipline's shared methodology, ensuring that age and sex estimates are comparable across analysts and collections. Because the relationship between skeletal change and chronological age is variable, the method emphasizes multiple indicators and explicit uncertainty.	Stable isotope paleodiet and mobility analysis is the methodology by which bioarchaeologists turn the isotopic chemistry of bone and tooth into quantitative statements about what people ate and where they lived. It rests on a chain of disciplined procedures rather than a single measurement: screening extracted collagen for diagenetic integrity using carbon-to-nitrogen atomic ratios, anchoring human values to a locally measured faunal baseline, quantifying trophic position from nitrogen-15 spacing, partitioning C3 versus C4 and marine carbon sources using the offset between collagen and apatite, and reconstructing residential mobility from biologically available strontium isotopes in tooth enamel. Bentley's review of strontium in the archaeological skeleton and Evershed's account of the biomarker revolution together frame the geochemical and analytical principles that make these inferences defensible.
