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.
The following forms have been recognized in the Upper Pliocene fauna from the karstic deposits near Działoszyn: Mioproteus wezei sp. n. (Proteidae), Palaeobatrachus sp. and Pliobatrachus cf. langhae (Palaeobatrachidae), Pelobates fuscus (Pelobatidae), Bufo bufo (Bufonidae), Rana sp. (Ranidae), Emys orbicularis antiqua (Emydidae), Ophisaurus pannonius and Anguis cf. fragilis (Anguidae), Lacerta cf. viridis and Lacerta sp. (Lacertidae), Elaphe paralongissima and Natrix cf. longivertebrata (Colubridae). The majority of the recognized taxa, including living forms (e.g. Bufo bufo, Emys orbicularis, Anguis fragilis) as well as extinct ones (Pliobatrachus langhae, Natrix longivertebrata), were widespread in the European Neogene and (eventually) Pleistocene.
