Here is a unique piece of jewelry featuring a real cut and polished ammonite fossil from Madagascar. The 1 inch wide ammonite approximately 110 million years old and from the genus Desmoceras.
Ammonitesare 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.
