The description of an ammonite fauna from the "Oolithe de Balin" allows to partly revise the taxa described in the last century by WAAGEN, NEUMAYR, UHLIG, TEISSEYRE and SIEMIRADZKI in this famous Middle Jurassic formation of Southern Poland. The recognized taxa belong to the genera Phlycticeras, Paroxycerites, Paroeocotraustes, Alcidellus, Clydoniceras, Homoeoplanulites, Bullatimorphites and Macrocephalites. The stratigraphic range of their species concerns a Late Bathonian (Retrocostatum Zone and Discus Zone) to Early Callovian (Herveyi Zone, Koenigi Zone and Calloviense Zone pars.) interval, possibly also the base of the Middle Callovian. The comparison between this fauna and the Western Europe ones, especially those recently described from the Swabian and Franconian Jura in South Western Germany, allows to reconsider the validity of several taxa; the taxonomic status of Macrocephalites jacquoti (H. DOUVILLÉ), which must be considered as a nomen oblitum, is especially discussed. The ferrugineous deposits of Balin are condensed and reworked (partly by the quaternary periglacial effects), and located at the Bathonian - Callovian boundary; the ammonite fauna has a typically submediterranean composition.
