Gastropoden aus dem oberen Callovium (Lamberti-Zone) der Tongrube Dubki bei Saratov, Rusische Plattform

Abstract

Nineteen gastropod species are discribed from the Lamberti zone (Upper Callovian) from Dubki/ Russia; seven species and one genus (Gerasimovcyclus n. gen.) are new. Close relationships exist between the fauna from Dubki and contemporaneous faunas from Middle and Western Europe (occurrence of identical or closely related species).
