Harzhauser et al., 2002, p. 117:

  • "A second Impact on Proto-Mediterranean-Atlantic mollusc faunas was the Messinian salinity crisis in the Late Miocene, when the marine Fauna of the Mediterranean basins was strongly impoverished (Hsü et al., 1978). The gastropod Fauna of the Mediterranean basins probably vanished completely - except for some supposed shelters such as the ´Andalusian sanctuary´ (see Demarcq, 1987) - due to desiccation throughout the Mediterranean. The Fauna of the Eastern Atlantic coasts was less affected. After the salinity crisis the deep-water Fauna was distinctly impoverished (Raffi and Taviani, 1984), but it had not such a catastrophic effect on shallow marine molluscs (Sabelli and Taviani, 1984), which recolonised the Mediterranean basins from the Atlantic. Nevertheless, the Messinian salinity crisis caused a turnover in composition of the nearshore Fauna. Post-Messinian gastropod faunas lack characteristic Miocene taxa, such as Terebralia bidentata (Defrance), Melongena cornuta (Agassiz), Polinices redempta (Michelotti) or Perrona jouanetti (Desmoulins). In fact, many of the conids, turrids and turritellids of the Proto-Mediterranean-Atlantic Region became extinct (cf. Dermitzakis and Georgiades-Dikeoulia, 1987). Hence, the post-Messinian gastropod fauna represents rather the ancestral, warm-water stock of the modern Mediterranean-Atlantic Region."
