“…Orszag-Sperber 2006; Roveri et al 2008a). In this low-salinity environment, some evidence of the permanence of the Atlantic connections is given by the occurrence of marine fish (Carnevale et al 2008) and alkenons (Mezger 2012). The return to normal marine conditions is sudden and marks the base of the Zanclean at 5.33 Ma, and is usually interpreted as being related to a catastrophic re-opening of the Atlantic connections.…”

A general agreement on what actually happened during the Messinian salinity crisis (MSC) has been reached in the minds of most geologists but, in the deepest settings of the Mediterranean Basin, the picture is still far from being finalized and several different scenarios for the crisis have been proposed, with different significant implications for hydrocarbon exploration. The currently accepted MSC paradigm of the 'shallow-water deep-basin' model, which implies high-amplitude sea-level oscillations (> 1500 m) of the Mediterranean up to its desiccation, is usually considered as fact. As a consequence, it is on this model that the implications of the MSC events on the Mediterranean petroleum systems are commonly based.In fact, an alternative, deep-water, non-desiccated scenario of the MSC is possible: it (i) implies the permanence of a large water body in the Mediterranean throughout the entire Messinian salinity crisis, but with strongly reduced Atlantic connections; and (ii) envisages a genetic link between Messinian erosion of the Mediterranean margins and deep brine development.In this work, we focus on the strong implications of an assessment of the petroleum systems of the Mediterranean and adjoining areas (e.g. the Black Sea Basin) that can be based on such a non-desiccated MSC scenario. In particular, the near-full basin model delivers a more realistic definition of Messinian source-rock generation and distribution, as well as of the magnitude of water-unloading processes and their effects on hydrocarbon accumulation.

“…According to the traditional interpretation, the Mediterranean basin previously desiccated during the Salinity Crisis, would have been refilled with fresh and brackish water of Parathethyan origin (Cita et al 1978;McCulloch & De Dekker 1989;Krijgsman et al 1999) up to the normal marine conditions were restored at the beginning of the Pliocene with the Zanclean flooding. Nonetheless, the occurrence of marine stenohaline fishes (Carnevale et al 2006a, b) and the geochemical data from fish otholiths and other fossils from some localities of central Italy (Carnevale et al 2008) indicate that at least at the end of the Messinian the Mediterranean basin was already characterized by normal marine conditions. The Messinian deposits are therefore overlain by the Zanclean deposits of the Argille Azzurre Formation consisting of marine shales and marls (Dela Pierre et al 2007;Mosca et al 2010).…”

“…Even so, this epoch was warmer than today, even if it had a less or equal p CO2 compared to pre-industrial levels (≤ 390 ppm) [5]. During the Miocene several major important climatic events took place: the Miocene Climatic Optimum (MCO) [6,8,9], the beginning of the Arctic glacia-tion [4,10], the two European washhouse events [11,12] and the Messinian Salinity Crisis [13][14][15][16][17][18]. All these events induced changes in European climate, and the MCO appears as the first Neogene climate event with potential to be used as a climate analogue for future climate projections.…”

A review of the entire Neogene climate in Europe is a useful tool for climate researchers, synthesizing present day knowledge on a variety of past warmer climate modes thus facilitating the debate regarding possible future climate scenarios in the Old Continent. This work centres on the European scenario, debating possible future projections and describing the Miocene and Pliocene climate in the Old Continent. With present evidences of a global warming scenario, it is highly important that we look at past climatic events in order to better predict future climate changes impact in biodiversity. The review presented here synthesizes the literature regarding climate, faunal and floral evolution for the European Neogene, and aims to help palaeoclimatic researchers and climatologists to characterize some of the boundary conditions for modelling possible analogous of IPPC climate scenarios. If the future climate projections come to be true, it is shown that the Pliocene, and particularly the Mid Piacenzian Warm Period, should be considered as the best analogue for the impact of a warming climate in Europe.
