Upper Permian ostracode assemblage from the Jadar Block (Vardar zone, NW Serbia)

Ostracodes from the Changhsingian (latest Permian age) in the uppermost part of the “Bituminous Limestone” Formation of the Komiri Section in NW Serbia (Jadar Block, Vardar Zone) are described and illustrated. Three new species of ostracodes are introduced: Basslerella jadarensis n. sp., Acratia serbianella n. sp., and Knoxiella vardarensis n. sp. The ostracode assemblage, together with conodonts and foraminifers, is the first record of the youngest Late Permian age microfaunas from Serbia and from the central part of the Balkan Peninsula.
