Abstract

Ammonites of subfamily Leptosphinctinae, ancestral to Perisphinctoidea, are revised based on the study of new collections from the lower part of the Upper Djangura Subformation (beds with Orthogarantiana humilis of the Upper Bajocian Strenoceras niortense zone) at the village of Krasnogorskaya on the Kuban River (Russia, Karachay-Cherkessia). The macroconchs of Leptosphinctes (Leptosphinctes) kardonikensis (Kakhadze et Zessashwili) and L. (L.) stephanoceratoides (Kakhadze et Zessashwili), associated with the microconchs L. (Kubanoceras) asinus (Zatwornitzky) and L. (K.) paucicosta (Kakhadze et Zessashwili), are described. These taxa are earliest representatives of the genus Leptosphinctes known from the modern territory of Russia.
