The data on the taxonomic composition and stratigraphic distribution of ammonites of the families Perisphinctidae and Parkinsoniidae from the Bajocian and Lower Bathonian of the Kuban-Urup interfluve are summarized. The age of Infragarantiana primitiva (Wetzel), the oldest species of Perisphinctoidea in the Northern Caucasus originating from the Lower Bajocian Humphriesianum Zone, is clarified.
