8.5" Split Fossil Ammonite Pair - Agatized

Here is an large, 8.5" wide, cut and polished Cleoniceras ammonite fossil from the Cretaceous of Madagascar. It exhibits gorgeous mineralization within the chambers, each separated by white calcite scepta (divisions). The reverse side has a very beautiful, mother of pearl look to it. This highly polished, exotic ammonite makes a superb display piece with tremendous historical appeal. Most of the chambers in this specimen have been preserved as deep, crystal lined pockets, making it almost like a fossil geode.

This is an exceptional pair as these ammonites rarely reach this size and when they do typically are not preserved this exquisitely. It comes with a pair of display stands.

Ammonites are an extinct group of marine invertebrate animals which died out at the end of the Cretaceous period. These mollusks are more closely related to living coleoids (i.e. octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species.
