背面描述 The reverse features a large, naturalistic depiction of an ammonite fossil set into the coin's field, with the actual black ammonite specimen embedded within the design. The intricate spiral chambered shell of the ammonite is rendered in fine detail, showcasing the characteristic logarithmic coiling and suture patterns of the cephalopod. The fossil insert is dark in color, contrasting with the antique silver finish of the surrounding field. The overall composition emphasizes the prehistoric organic specimen as the central artistic and collectible element of the issue.

附加信息

Burkina Faso has no mint of its own; its commemorative issues are struck under contract, typically at the Monnaie de Paris or through private minting houses in Europe. The ammonite series to which this piece belongs targets the natural history collector market rather than any domestic monetary purpose — these coins are legal tender in name only, issued at face values a fraction of their actual cost.

Ammonites became extinct at the K-Pg boundary roughly 66 million years ago, the same event that ended non-avian dinosaurs.
