Abstract

This study aimed to examine the degradation of juvenile skeletal remains with respect to adult counterparts from different burial settings in Milan, Italy. A multiscale and multimodal approach was applied to investigate bone diagenesis by combining chemical and mineralogical analyses with synchrotron radiation-based virtual histology. Certain differences could be observed between child and adult skeletal remains; juvenile bones exhibited (i) poorer histological conservation, with prominent general re-organisation of the observed three-dimensional original microstructure, resulting in denser structures with low porosity; (ii) bioapatites with low defective structures, with chemical compositions highly site-sensitive, exhibiting variation even within a single bone; (iii) organic matter highly variable in terms of quality, quantity, and arrangement, even within a single bone sample. Conversely, organic decay results in similar enrichment in calcium content both in juveniles and in adults. In conclusion, the present work points out high intra-individual skeletal preservation in archaeological juvenile bones with respect to adults, thus suggesting that immature and mature bone tissues deteriorate at different rates, foremost as a function of their intrinsic features (shape, porosity, histological structures, etc.), and secondarily under the influence of the burial environment.
