Abstract
A study of the third lower molar and the second and third upper molars of Gazellospira torticornis found in the Villafranchian (Quaternary) deposit of Saint-Vallier (Drome, France) is presented. Comparison with specimens from Spain indicates a size decrease. Spain and France were two distinct climatic provinces during the Villafranchian, with similar faunas differing from each other only in the frequency of species.
