Abstract: The Milivojevica Kamenjar section in Druzetic (NW Serbia) is the most diverse Carbonifer-
 ous ammonoid occurrence on the Balkan Peninsula.  It contains two faunal complexes, an early Late
 Visean and a fauna from the Visean-Serpukhovian boundary. The early Late Visean assemblage is simi-
 lar to time equivalent occurrences of the North Variscides and north-western Africa. lt is integrated in a
 cosmopolitan ammonoid distribution of this time interval.  The Visean-Serpukhovian boundary assem-
 blage is very different to its time equivalents from the North Variscides and as a result indicates provin-
 cialism; it belongs to the South Variscan-North Gondwanan faunal realm and is closely related to the
 occurrences in the Cantabrian Mountains of Spain and the South Urals.
