Abstract ---The youngest Late Famennian ammonoid assemblage from Russia is described from the Kiya Formation in the Orenburg Region. It contains wocklumeriids and parawocklumeriids, taxa relatively common in Western Europe but scarce in the Urals. The ammonoid community of that age inhabited the relatively deep zones of the western realms of the Uralian Ocean (near the eastern coast of Baltica) and was formed during the progressive reduction of connections between the Uralian Ocean and basins of the Subvariscan Realm. By the end of the Famennian, the diversity and abundance of ammonoids in this territory was significantly reduced. The terminal Famennian assemblages contain clymeniids with barrel-shaped, spheroconic, and triangular shells. The new species  Synwocklumeria elata  Nikolaeva sp. nov. is a member of the rarely found genus  Synwocklumeria with a triangularly coiled inflated shell at all growth stages.
