| Sumario: | 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 permanent and second deciduous molars (M2and dm2) ofH. sapiens, H. neanderthalensis and Atapuerca-Sima de los Huesos (SH) hominins. In modernhumans, talonid crests are described exclusively in the deciduous teeth (Korenhof, 1982)and interpreted as a primitive mammalian remnant of the talonid attachment to the trigo-nid. Here we report for the first time the expression of talonid crests of deciduous andpermanent molars in H. sapiens, H. neanderthalensis and Middle Pleistocene hominins. Wediscuss possible evolutionary interpretations and suggest the importance of recording thisfeature in future studies. |
