The Ammonoidea were a huge group of mollusks, mostly with coiled shells, that lived in the seas and oceans. They started to establish themselves in the Early to Mid Devonian Period, from about 400-390 million years ago. Different subgroups came and went, some becoming incredibly numerous and widespread, until the end of the Cretaceous Period, some 330 million years later. Ammonoid subgroups included goniaties and ceratites and the ammonites. Together with belemnoids and nautiloids, as well as squid, octopuses and cuttlefish, the ammonoids are included in the major cephalopod, or ‘head-foot’, group of mollusks.To the right; black/white Goniatite wired in silver with lava stone beads, pewter chain and spacers.
Fossils are always fun to learn about and exceptional pieces to work with in jewelry. I’ve been able to wire work many pieces, including Ammonites and Goniatites. Visit our website for these and other fossil jewelry designs.
