Silicified ammonite (Cleoniceras sp) (side B)

3D ModelNoAI

Locality: Madagascar

No.: 2113 (B)

Size: 13 x 10 x 1.6 cm

Description: This specimen represents one polished side of Cleoniceras ammonite. 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. These ammonites present impressive mineralization, both in their outer shell and in their chambers and internal structure. The mineralization is represented by chalcedony, jasper, and quartz.
