摘要：

Ammonites of a new genus, Kislovodskoceras gen. nov., with the type species K. kislovodskense sp. nov. (fam. Desmoceratidae), are described from the Middle Aptian of the vicinity of Kislovodsk. The shell shape and sutural ontogeny are discussed. Findings of the new taxon are confined to the middle part of the Epicheloniceras subnodosocostatum Zone, for which the position of the lower boundary in sections of the vicinity of Kislovodsk is revised.
