Nipponites

phylum	Mollusca	Nipponites ("stone of Nippon") is an extinct genus of heteromorph ammonites. The species of Nipponites (primarily N. mirabilis) are famous for the way their shells form "ox-bow" bends, resulting in some of the most bizarre shapes ever seen among ammonites. The ecology of Nipponites, as with many other nostoceratids, is subject to much speculation. For more information, visit the Wikipedia entry. Get back to Ammonites
