Family Clydoniceratidae

The geographical distribution of this group extends from Madagascar to Europe, while passing by Arabic peninsula and North Africa. It is well confined in the middle Jurassic (Bathonian). Rather rare in the lower bathonian deposits, with only one genus, Micromphalites, it is more frequent, at the top of this stage, with the genus Clydoniceras and the sub-genus Delecticeras.

Genus Micromphalites

This ammonite is more often found in Saudi Arabia than in France, but it has been recognized in the lower Bathonian of the department Nièvre.

It is an involute ammonite with a circumumbilical bulge and thick ribs. A tall keel crosses the venter. This picture shows a damaged specimen.
