La faune malacologique des calcaires éocènes de la région de Sabarat (Pyrénées ariégeoises)

Limestone beds included in the «Poudingue dePalassou around Sabarat (Ariège) contain a Gasteropod fauna known since J.-B. Noulet's works (1857). The systematic inventory of the different localities and the paleontological study of the material collected prove that two successive and clearly different Mollusc faunas existed. The bartonian fauna with Ischurostoma formosum minutum (Noulet) and Biomphalaria vasseuri (Roman) is preceded by a lower lutetian fauna with Biomphalaria pseudoammonius (Scholtheim): in the latter, two paleoecological groups are opposed according to the sheltered channels of two kinds in which limestones beds have been built. Besides, the chronostratigraphic consequences imply that the middle part of the «Poudingue de Palassou has been formed from Lower Lutetian to Bartonian.     

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.
