Article history: Abstract Manuscript received September 02, 2015 Middle Miocene deposits at the Dubravica locality in SW Medvednica Mt. (N Croatia) contain Revised manuscript accepted March 03, 2016 various marine fossils, including one tooth of the surgeonfish (Acanthuridae). This is the first Available online May 16, 2016 such record in Croatia and the second in the wider region, besides the Vienna Basin. The appearance of surgeonfishes in the Paratethys coincides with the Miocene thermal maximum. Their Keywords: Central Paratethys, Medvednica Mt., distribution was probably controlled by available reef habitat and their palaeobiogeography and Miocene, Badenian, Acanthuridae migration routes are yet to be studied.
