“…On the other hand, the new stable isotope data differ distinctly from Miocene marine and brackish isotope signatures of adjacent systems. A large amount of stable isotope data on mollusc aragonite from the Central Paratethys has been published by Latal et al (2004Latal et al ( , 2005Latal et al ( , 2006 and Harzhauser et al (2007b). Data on Lake Pannon were provided by Geary et al (2002), Mátyás et al (1996) and Harzhauser et al (2007a, b).…”

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.

Sixty-seven spe cies of ben thic and twenty-one spe cies of plank tonic foraminifers are re corded in the 12-m-thick sec tion of the M³yny bore hole. Ben thic as sem blages are char ac ter ized by the dom i nance of Bulimina and Uvigerina while plank tonic as sem blages are com posed mainly by warm-wa ter orbulinids and Globigerinoides spp. in the lower part of the M³yny sec tion and by tem per ate-cold wa ter Globigerina spp. in the up per part of the M³yny sec tion as well as the Leszcze and Borków sec tions. The tax o nomic com po si tion of foraminiferal as sem blages makes it pos si ble to dis tin guish two foraminiferal zones in the M³yny bore hole: the Orbulina suturalis and Uvigerina costai zones, and only the lat ter zone is ac ces si ble at Leszcze and Borków.

“…The rapid changes in relative sea−level combined with the tectonic activity in an active back−arc/ fore−arc basins system may have led to a series of separations and reconnections of shallow marine faunas. Large scale sepa− rations of the north−eastern branch of the Paratethys (e.g., Pol− ish−Carpathian Foredeep) and the southern parts (Pannonian basins complex) also had significant impact on the stable iso− tope composition of the sea−water (Latal et al 2006). Thus, the geographic isolation of populations might have had a strong impact on speciation as already documented for some nas− sariid gastropods (Harzhauser and Kowalke 2004).…”
