Cleoniceras sp, Parona and Bonarelli 1897 (ammonite)
Cephalopoda - Ammonitida - Cleoniceratidae
Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls.
