Le levantin de Joanina (Épire,Grèce): Observations stratigraphiques et paléontologiques

Within the Joannina serie, the molluscan fauna are found at two levels. An evolution has been observed within the Paludina group, but with lesser morphological development than those observed at Slavonia (Yougoslavia) and in the Island of Kos (Greece). Moreover, the gyrogonites, pollens and ostracodes demonstrate an increase in salinity during deposition and also give an Upper Pliocene age to this lacustrine serie.
