“…Throughout the Neogene, the family Melanopsidae was very dominant and even increased its number of species over time. Particularly in the long-lived Lake Pannon, Lake Dacia, and the lakes of the Dinaride Lake System it played an important role and formed several independent endemic lineages (e.g., Geary, 1990;Glaubrecht, 1993Glaubrecht, , 1996Bandel, 2000;Geary et al, 2002;Neubauer et al, 2011Neubauer et al, , 2013b. The high relative abundance of up to 16.9% contrasts the present pattern with only 18 species for the whole of Europe (1.7%).…”

For the first time a palaeobiogeographic framework is proposed for European Neogene freshwater systems. The distribution of 2226 species-group taxa of freshwater gastropods from over 2700 Miocene and Pliocene localities was evaluated. The localities were grouped into palaeo-freshwater systems based on latest palaeogeographic reconstructions. Cluster analyses were computed for four time slices, i.e., Early Miocene, Middle Miocene, Late Miocene, and Pliocene. The analyses demonstrate a generally high degree of provincialism for the Neogene freshwater systems and allow the definition of biogeographic units. The delimitations are based on the cluster analyses, the degree of endemicity, and geographical coherence. The Early Miocene is characterised by a relatively low degree of provincialism suggesting the distinction of three regions. Coinciding with the development of many endemic systems on the Dinarian-Anatolian Island and in central Europe, the Middle Miocene demonstrates a higher degree of provincialism, allowing the definition of six biogeographic regions. With the onset of the Late Miocene the retreat of the Central Paratethys and development of the huge Lake Pannon massively shaped faunal evolution and palaeobiogeography in general. The formation of the 'Lago-mare' environment fringing the Mediterranean Basin as well as the development of several restricted freshwater systems in western Europe additionally promoted biogeographic division. The increasing provincialism allowed the delimitation of six biogeographic regions, three of which could be subdivided into seven dominions. With the disappearance of Lake Pannon and the decline of western European and Mediterranean faunas at the Miocene-Pliocene boundary, biodiversity hotspots shifted towards eastern and southeastern Europe. For the Pliocene, four biogeographic regions, five dominions, and four provinces were defined. Most of the here proposed biogeographic units and faunal differences are governed by the varied existence of large, long-lived systems. Because of their prolonged duration they immensely influenced the community composition on the family level, differences of the relative species richnesses per biogeographic region, and the rising rate of endemicity. The underlying mechanism for this pattern is the ongoing continentalization of Europe triggered by the Alpidic orogenesis and the simultaneous retreat of the Paratethys Sea. The continuing restriction of this huge intracontinental sea from the Mediterranean promoted the evolution of endemic freshwater faunas. The arising long-lived systems like Lake Pannon, Lake Dacia or Lake Slavonia persisted over several millions of years and stimulated the evolution of highly diverse and endemic faunas.

Stable isotope composition of the Miocene Dinaride Lake System deduced from its endemic mollusc fauna

The aragonite shells of 55 mollusc specimens from the late Early and early Middle Miocene of two palaeolakes of the Dinaride Lake System (DLS) are analysed for their d 18 O and d 13 C signatures. The data set has a bimodal distribution with a prominent peak between -3 and -4% for both isotopes and a second much weaker peak at more depleted values of c. -9 to -7%. Taxa with 'heavy' values are interpreted to represent the inhabitants of the shores or shallow areas of the lake. Depleted values are attributed to species preferring freshwater habitats of springs or small rivulets, thus representing the freshwater end-member. The overall rather high values in both stable isotopes result from a combination of evaporation effects and the influx of already isotopically heavy freshwater from the karstic catchment area. Thus, the DLS is interpreted as a closed freshwater system without marine influence but with enough contribution of freshwater to keep the oxygen values close to -5%. Mean lake surface water temperatures, based on the d 18 O shell values, excluding the freshwater end-member taxa, range around roughly 19-21°C. Despite the problems in calculating these temperatures, the values are in agreement with mean annual air temperatures deduced from the palaeobotanic record by applying the Coexistence Approach method. The seasonal range was around 10-11°C and is mainly recorded in shells from lake settings. Taxa with freshwater end-member signatures lack this range due to the more stable temperature regime and less fluctuating dissolved inorganic carbon (DIC) pool. Congeneric species from the same stratigraphic horizon often display discrete but different isotope signatures. This fact suggests habitat segregation and might be a major factor for sympatric speciation and the endemic radiation within the mollusc fauna of the DLS.

“…This iterative action has been documented in numerous fossil groups (Aubry, 1988;Haas, 1942;Geary et al, 2002), but was obscured by the relatively simple morphology of these microfossils. Detailed stratigraphic investigation has clarified a number of inconsistencies within current Eiffellithus biostratigraphic datums, and suggests potential steps to reconcile these issues.…”
