Fossil remains of the extinct boine snake Bavarioboa, thus far known exclusively from several localities of western and central Europe, are reported for the first time outside Europe. The new fossil record is from the Mendikdere Formation in easternmost Turkey, dated Late Oligocene to Early Miocene. The finding provides strong evidence of links connecting ophidian faunas of Europe and southwestern Asia in the past, and confirms the supposition that Anatolia may have had close terrestrial connections with Europe around the Oligocene/Miocene boundary.

We describe the first record of a late Oligocene or early Miocene freshwater gastropod fauna from the Susuz Formation of the Oltu-Narman Basin in northeastern Anatolia. The assemblage consists of only six species, indicating the presence of a well-oxygenated lake, pond or anabranch rich in vegetation. Only two of the taxa are related to European Oligo-Miocene species. The fauna might be the first indication of a yet undocumented Eastern Anatolian freshwater biogeographic region, characterized by high endemism and minor influence from the coeval Peri-Paratethyan and Aegean–Anatolian regions in the west. The biostratigraphic value of the assemblage is low but might rather point to a Miocene age of the upper part of the Susuz Formation. Theodoxus susuzianus, Bithynia erzurumensis, and Valvata koehleri are described as new species.
