Summary
Dental hard tissues contain periodic incremental markings that can be used as an absolute temporal archive to reconstruct their growth and can incorporate trace elements into their chemical structure during formation that reflect diet, the environment, metabolism, and health. The growth history can be recovered from teeth using virtual tooth histology to resolve a continuous record of trace element composition within each of the mineralized dental tissues, to further our understanding of past life history events in extant and extinct taxa. While acellular cementum forms slowly and regularly and is ideal for recording annual increments, compensatory cellular cementum can mirror this regular growth through gradual physiological changes in anterior tooth inclination. Here, we document this growth through microstructural elemental mapping using non-destructive synchrotron x-ray fluorescence on chimpanzee dental thin sections. We evidence clear seasonal mineral fluctuations, and match the narrower, brighter incremental markings visible in TLM with peaks in mineral concentration in zinc and strontium.
