N2 - Three different ammonoid assemblages of Anisian age are described from the Anisian Bulog Group of the Kovčezi sectionin the Durmitor Mountain (northern Montenegro/Dinarides). The Illyrian is represented by a succession belongingto the Komarani and Bulog Formations, together approximately 50 m thick. The Komarani Formation of late Illyrian ageconsists predominanty of oligomictic breccias and mass-transport deposits that contain redeposited Bulog Limestoneblocks with Pelsonian ammonoids. Within the late Illyrian Bulog Formation above the Komarani Formation, two distinctcondensed nodular limestone levels contain rich ammonoid faunas. In total 36 taxa could be determined, belonging to24 genera of the Aplococeras avisianum and Nevadites secedensis zones. Ptychites rugifer (Oppel), Megaphyllites obolusMojsisovics, Parakellnerites rothpletzi (Salomon), Apleuroceras decrescens (Hauer), Proteusites labiatus (Hauer), Tropigastriteslahontanus Smith, Proarcestes pannonicus (Mojsisovics) and Proarcestes subtridentinus (Mojsisovics), and the genus Aristoptychitesare for the first time described from Montenegro (south Central Europe).
