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