Microcomputed tomography (laboratory and synchrotron) of intact archeological human second metacarpal bones and age at death

摘要: Laboratory microcomputed tomography (microCT) and synchrotron microCT imaged intact human second metacarpal bones (mc2) from two UK archeological sites: Ancaster (3rd to 4th century CE) and Wharram Percy (11th to 14th century CE). Two female mc2 were studied from each of three age at death cohorts (young, 18–29 years; middle, 30–49 years; old ≥50 years) along with a modern control mc2. The present investigation is complementary with an X‐ray scattering study of the same mc2 where the authors found no age‐at‐death‐related changes in carbonated apatite lattice parameters and found collagen D‐period peaks in the small angle regime in a minority of the mc2. This led the present authors to ask whether microCT could assign mc2 to the age cohort estimated by dental wear and whether material between bioerosion porosity and apparently free of diagenetic changes correlated with presence …
