Description

Ammonite Cleoniceras sp.sectioned and polished.
This atypical black color of this ammonite specimen is due to the presence of Manganese pergola inside the rock after the fossilization of the shell.
Coming from the province of Mahajanga in Madagascar, this ammonite has been cut and polished, exposing its beautiful chambers, in some of which crystallizations of quartz can be seen.
