Talonid crests expression at the enamel–dentine junction of hominin lower permanent and deciduous molars

The application of microtomography (mCT) to dental morphological studies has unveileda new source of palaeobiological information, particularly in the analysis of the internalstructures of teeth. In this study, we assess the expression of talonid crests at the enameland dentine surfaces in lower per...
