Abstract: The Hungarian occurrence of the late Valanginian to earliest Hauterivian ammonite genus Oosterella is reviewed. Earlier descriptions indicated only the presence of O. cultrata in the Gerecse Mts. Recent observations proved that the genus is present also in the southern part of the Transdanubian Central Range, in the Bakony Mts. Oosterella cultrata, O. cultrataeformis, O. gaudryi, O. vilanovae, O. fascigera, O. ondulata, O. begatsrensis and a possible new species, described here as Oosterella. sp. 1, were documented in the Hungarian collections. Some specimens have a stratigraphic control, coming from bed-by-bed collected cephalopod assemblages. The majority of the Hungarian Oosterellidae was found in the Late Valanginian Peregrinus Zone, and a single species was described form the Uppermost Valanginian Furcillata Zone, while beds assigned to the Lower Hauterivian yielded no oosterellids.
