| Abstract: | The study of Plaissan rodent fauna and the discoveryof a new fossiliferous locality, 〈Nouvelle Faculté Médecine〉, allow us to contribute to a more accurate biochronological mammalian scale, for the Bas-Languedoc Lower Miocene. Nouvelle Faculté Médecine, contemporaneous of La Paillade or slighthy older has a Aquitanian age; Plaissan, equivalent to Paulhiac, ist older than the oldest known interbedded marine level in the Languedocian marine Aquitanian (Les Cévennes); it should be contemporaneous with the ante-stratotypic Aquitanian of Carry-le-Rouet. |
