The study of tooth morphology provides eco-indicators providing information on the mechanical capacities of teeth, reflecting the natural selection of dental phenotypes which has been active over a long period (of the order of 1 million years).
Once the tooth is worn out, the eco-indicators of this dental morphology potentially provide information on the nature of the bolus.
