Preliminary analysis of M1 of Late Pleistocene and Recent populations of Terricola savii from Italy (Arvicolidae, Rodentia)
No full textThe main object of this research is the study of the variability degree of the first lower molar in Late Pleistocene and living populations of Terricola savii in Italy (whose conspecificity has been proved by genetic analyses) and its comparison with that of fossil populations (assigned to T. savii on a morphological basis) in order to find a way to attribute isolated fossil remains to specific systematic groups. On this basis, we attempted to establish, through different analyses and direct observations on the occlusal dental surface morphology, the relationships that exists between fossil and living populations, and to verify the existence of a temporal and/or geographic cline
