Palaeontological investigation of the Pliocene Tahria and Slama formations in the Lower Chelif Basin (NW Algeria) led us to collect significant gastropod assemblages for taxonomic and taphonomic purposes. There is presently a very complete inventory list of Pliocene gastropods from Algeria, with 16 species from the Zanclean Tahria Formation and 54...

The Miocene Paratethys Sea is frequently depicted as junction between the Proto-Mediterranean Sea and the Indian Ocean. Herein, we elucidate the biogeographic character of this large epicontinental Miocene sea based on its speciose gastropod fauna. We debunk the persistent myth that there was a connection between these marine realms during Langhian...

Gourmya belongs to a group of molluscs, which originated during the Paleogene in the Western Tethys and along the Eastern Atlantic coast but then established in the IWP Region during the Neogene. Similar patterns have been observed by Harzhauser et al. (2007, 2008) for tridacnine bivalves and certain strombids. In this paper we describe an extremel...

The Miocene Climate Optimum (MCO, ~ 17-14 Ma) was a time of extraordinary marine biodiversity in the Circum-Mediterranean Region. This boom is best recorded in the deposits of the vanished Central Paratethys Sea, which covered large parts of central to southeastern Europe. This sea harbored an extraordinary tropical to subtropical biotic diversity....

The Miocene mollusc fauna of Karaman basin is highly diverse and excellently preserved. The Tırtar formation was dated to late Serravalian age using integrated biostratigraphical data of benthic gastropods, pteropods, nannoplanktons and foraminifers (Janssen, R. 1993; Janssen A.W., 1999; Coric et al. 2012; Landau et al. 2013). The gastropod assembl...

We describe the first shallow marine and hard-ground associated gastropod assemblage from the Ottnangian (Early Miocene) of the Central Paratethys Sea. In many cases, the poor and usually fragmentary preservation as casts and moulds does not allow a definitive identification. Nevertheless, the small assemblage – comprising 32 species-level taxa – s...

Zeidora ligustica Bellardi, 1878, and Bogia labronica (Bogi, 1984) are added to the list of gastropods known from the Pliocene of the Estepona Basin.
